▼ Australian First World War historiography tends to focus on the ordinary soldier: his background, character and involvement in the war. This is a legacy left by Charles Bean who, following the history from below approach, believed in the need for soldiers’ stories to be told. On the other end of the spectrum, attention is given to political leaders and the British high command. British commanders and, by extension, other Allied commanders are too often portrayed as poor leaders who were reluctant to adapt to modern warfare, and did not demonstrate a sense of responsibility for the men under their command. The evidence shows that this perception is not accurate. A comprehensive understanding of the progression of Australian forces on the Western Front cannot be gained without investigating the progression of those in command.This thesis examines the brigade commanders of the Australian Imperial Force who held that level of command for a substantial period while on the Western Front. These commanders challenge preconceived notions of First World War commanders, as they continually developed tactics and adapted to modern warfare as it evolved. They embraced new technology and ensured that their formations were able to effectively work with it. As the war progressed, they gained an appreciation of the importance of collaborating with other formations and ensuring effective communication, and demonstrated an understanding of the challenges of war on the Western Front. By 1918, the brigade commanders were effective leaders who undoubtedly played a significant role in the success of the Australian forces.

Sedative and analgesic effects of detomidine or

▼ There are approximately forty two million
donkeys in
the world. All developing countries have an expanding population of
donkeys, which are used for the provision of various services. The
most commonly performed procedures in
donkeys are castrations,
tumour removals, foot care and dental treatments. All of these
procedures can be performed in standing
donkeys provided sufficient
analgesia and sedation are provided. The donkey should be
recognised and treated in its own light. Very few analgesics
relieve pain without producing side effects. The ideal analgesic
would provide good analgesia and sedation without any side effects.
Combined with sedation, analgesia aids in the handling of animals
and reduces the danger to attendants. Neuroleptanalgesia provides a
more potent sedative and analgesic allowing more procedures to be
performed. A marked synergistic effect between opioids and alpha2
adrenergic agonists is reported. Detomidine-butorphanol is used
extensively for equine sedation and analgesia in the United States
of America and Europe. Currently there is limited information
available on effective sedative and analgesic drugs or drug
combinations in
donkeys. Detomidine and xylazine, which belong to
the alpha2 adrenergic agonist group, have been described for use in
donkeys. No information exists on the use of opioid drugs or
opioid-sedative combinations in
donkeys. Detomidine produces
sedation and analgesia of a greater magnitude and a longer duration
than xylazine. Detomidine has been used to sedate horses for
diagnostic, therapeutic or minor surgical procedures and as part of
a premedication or an intravenous anaesthetic protocol. Detomidine
is a good analgesic. The duration of sedation and analgesia is dose
dependent. The sedation produced by detomidine alone is not always
satisfactory and some horses will respond to noxious stimuli with
well-directed kicks. For this reason, detomidine and butorphanol
are very often combined. Butorphanol is a synthetic mixed
agonist-antagonist opioid. The detomidine is given five minutes
before the administration of butorphanol or the butorphanol can
follow the detomidine. Sedation is easily extended by additional
doses of detomidine and/or butorphanol. This combination produces
profound sedation in which horses are apparently unaffected by
sounds, tactile stimuli and surrounding activity. It has been
suggested that
donkeys require a higher dose of detomidine for
sedation than horses. The recommended dose for
donkeys is 20-40
µg/kg. The degree and length of analgesia and sedation is dose
dependent. A dose of 5-10 µg /kg was found effective for sedation
and a dose of 20 µg /kg was effective for sedation and analgesia.
No recommended doses for butorphanol in
donkeys exist. Twelve
healthy male
donkeys were randomly divided into two groups. One
group received 10 µg/kg of detomidine while the other group
received 10 µg /kg of detomidine and 25 µg /kg of butorphanol.
Sedation was evaluated by a scoring system and characterised by
lowering of the head, relaxation of the upper eyelids,…

▼ The aim of this study was to investigate the
viability of laparoscopic testicular artery ligation as an
alternative to the more conventional castration methods in equids.
Twelve intact male
donkeys varying in age from 5 months to 13 years
were used in this study. Two of these
donkeys were castrated by
means of an open technique. The remaining
donkeys underwent
testicular artery ligation under laparoscopic guidance. Ligation of
the testicular artery was achieved by application of Filshie clips
under laparoscopic visualisation. This was performed with the
donkeys standing in stocks and sedated with a combination of
detomidine hydrochloride and butorphanol tartrate. The ten
donkeys
which underwent testicular artery ligation were unilaterally
castrated using an acceptable open castration technique on two
separate occasions. The first testes were removed at a specific
time period after testicular artery ligation, while the second
testes were all removed on the same day 9 months after the first
group of
donkeys underwent laparoscopic assisted testicular artery
ligation. The remaining two
donkeys which acted as controls
underwent a standard open bilateral castration procedure both
testes being removed on the same day. All the testes removed,
excluding one testis lost to the study, were evaluated
histologically. Four testes were used as controls. Thirteen testes
showed histological signs of ischaemic necrosis, degeneration
and/or atrophy. Three testes showed histological tubular
degeneration and atrophy as well as the presence of some normal
tissue. The remaining three testes were histologically unchanged.
One of the testes was accidentally misplaced at post mortem due to
human error. Avascular necrosis of the testicular tissue was not
successful in all the subjects. This technique shows promise but
further research is required.

▼ Abstract
Objective: to assess the effectiveness of the muzzle twitch in
donkeys
Animals: five
donkeys serving as their own controls
Procedures: painful stimuli were applied to a donkey with and without use of a muzzle twitch. Effectiveness was measured by use of behavioural, cardiovasculair (HR, HRV) and hormonal (ACTH, cortisol and ß-endorphins) parameters.
Results:
donkeys responded less to painful stimuli under influence of the twitch compared to the control group. Mean HR was significantly increased during the twitch procedure after applying the twitch. Administration of painful stimuli in the twitch procedure did not further increase mean HR. Mean HR during the procedure without the twitch significantly increased after applying painful stimuli. The use of the twitch resulted in a significant increase in mean plasma ACTH concentration.
The use of the twitch did not result in significant differences in mean plasma ß-endorphin concentrations.
Conclusions and clinical relevance: although twitching of
donkeys led mainly to a hormonal stress response without concurrent increases in ß-endorphin concentration, the response to painful stimuli was clearly less. Therefore, it is advisable to use a twitch for restraining
donkeys when to perform mildly painful and/or brief procedures.

▼ (1) Rate of increase was measured for feral donkey
populations in parts of northern Australia as the average
exponential rate of increase, r, in a population subjected
to substantial reduction.
(2) The annual rate of increase was estimated to be r =
0.21. This estimate was compared with the exponential rate
of increase in another recovering donkey population and
found to be in close agreement.
(3) Ultimate and proximate factors regulating the
abundance of feral donkey populations were examined by
monitoring and sampling two populations; one at or close to
equilibrium density, the other below equilibrium density and
recovering from reduction.
(4) The size of the population at equilibrium density
remained stable over the 12 months of monitoring while the
size of the recovering population increased by 20 percent
(r = 0.18/yr).
(5) Growth and body condition were significantly
depressed in the population at equilibrium density
suggesting that donkey populations are limited by the food
resources available to them.
(6) Breeding occured over a discrete season, with
births occurring between September and February.
11
(7) Fecundity was high, with more than 75 percent of
mature females breeding in each year, and was independent of
population density.
(8) Adult and juvenile mortality were density
dependent, with mortality over the first six months of life
the most important demographic factor influencing rate of
increase in donkey populations, and hence population
abundance.
(9) Implications of the estimated rate of population
increase for the cost of long-term control of feral donkey
populations were examined by constructing numerical models
predicting the relative cost of ongoing control.
(10) These models were constructed using functions to
describe density dependent variation in population
productivity and the cost per donkey removed.
(11) The cost of removing donkeys at various population
densities was estimated using predator-prey theory. The
cost, measured in hours of helicopter time per removal, was
found theoretically and empirically to take the form of an
inverted functional response curve, with cost saturated at
high donkey densities.
(12) The utility of models predicting the cost of
continuing pest control is illustrated by comparing the
relative costs of two potential strategies for feral donkey
control.

▼ The study was conducted to establish the type and severity of
Trypanasoma congolense infection in donkeys, particularly the clinical picture,
and to correlate this with the effects on draught power and the role these
animals play in the perpetuation of the disease. Five mature donkeys were
subcutaneously inoculated with 7.5 x 106 blood stream forms of T. congolense,
strain IL 3575. Three donkeys in adjacent fly proof stalls were kept as controls.
The donkeys were monitored clinically on daily basis for a period of three
months. Blood was collected from the jugular vein twice a week for
haematology and once a fortnight for serum biochemistry. Blood from the
marginal ear vein was drawn into heparinized capillary tubes for diagnostic
purpose. Thin buffy coat smears were made, stained in 1:5 Giemsa for 15 - 20
minutes and observed under oil-immersion for the presence or absence of
trypanosomes. Subinoculations into mice and sheep were done to verify whether
the trypanosomes observed in donkeys were viable and patho~enic. The degree
of anaemia in sheep and the rapidity at which mice died was the measure of
pathogenicity. Donkeys were euthanized after three months and thorough post
mortem examinations done. Samples were collected from the lymphoid organs,
heart, lungs, skeletal muscles, kidneys, gastrointestinal-tract, brain and glandular
organs whether showing gross lesions or not. They were fixed in ten per cent
formalin, embedded in paraffin wax, sectioned at thickness of 6pm and stained
with haematoxylin and eosin ( H & E).
The infection had a prepatent period of 29 - 41 days in donkeys. The
clinical picture indicated a subclinical infection with no signs but a positive
diagnosis was made using thin stained buffy coat smears. Pyrexia peaks
accompanying parasitaemic phases in ruminants and horses were lacking. The
respiratory and heart rates were elevated during the third month of infection
when pounding heart beats were picked on auscultation, and the mucus
membranes were pale. Attempts to quantify the parasites in blood using a
haemocytometer were unsuccessful because they were low in numbers and
appeared sporadically. These trypanosomes were morphologically similar to
those inoculated into the donkeys.
The results showed red blood cells to decrease by 46.7% ; the packed
cell volume by 41.6% haemoglobin concentration by 41.4% in the infected
donkeys. In the control group, the red blood cells decreased by 28.6%; the
packed cell volume by 22.2% and the haemoglobin concentration by 26.8%.
This indicated that a decrease of 18.1%, 19.4% and 14.6% in the red blood cell
count, packed cell volume and haemoglobin concentration, respectively in
infected animals was attributed to T. congolense infection. Mean corpuscular
volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin
concentration increased over pre-infection values by 15.8%, 30.1% and 6.3%,
respectively in infected animals. Thus the anaemia observed could
morphologically be classified as normochromic, macrocytic.…

▼ There are approximately forty two million
donkeys in the
world. All developing countries have an expanding population of
donkeys, which are used for the provision of various services. The
most commonly performed procedures in
donkeys are castrations,
tumour removals, foot care and dental treatments. All of these
procedures can be performed in standing
donkeys provided sufficient
analgesia and sedation are provided. The donkey should be
recognised and treated in its own light. Very few analgesics
relieve pain without producing side effects. The ideal analgesic
would provide good analgesia and sedation without any side effects.
Combined with sedation, analgesia aids in the handling of animals
and reduces the danger to attendants. Neuroleptanalgesia provides a
more potent sedative and analgesic allowing more procedures to be
performed. A marked synergistic effect between opioids and alpha2
adrenergic agonists is reported. Detomidine-butorphanol is used
extensively for equine sedation and analgesia in the United States
of America and Europe. Currently there is limited information
available on effective sedative and analgesic drugs or drug
combinations in
donkeys. Detomidine and xylazine, which belong to
the alpha2 adrenergic agonist group, have been described for use in
donkeys. No information exists on the use of opioid drugs or
opioid-sedative combinations in
donkeys. Detomidine produces
sedation and analgesia of a greater magnitude and a longer duration
than xylazine. Detomidine has been used to sedate horses for
diagnostic, therapeutic or minor surgical procedures and as part of
a premedication or an intravenous anaesthetic protocol. Detomidine
is a good analgesic. The duration of sedation and analgesia is dose
dependent. The sedation produced by detomidine alone is not always
satisfactory and some horses will respond to noxious stimuli with
well-directed kicks. For this reason, detomidine and butorphanol
are very often combined. Butorphanol is a synthetic mixed
agonist-antagonist opioid. The detomidine is given five minutes
before the administration of butorphanol or the butorphanol can
follow the detomidine. Sedation is easily extended by additional
doses of detomidine and/or butorphanol. This combination produces
profound sedation in which horses are apparently unaffected by
sounds, tactile stimuli and surrounding activity. It has been
suggested that
donkeys require a higher dose of detomidine for
sedation than horses. The recommended dose for
donkeys is 20-40
µg/kg. The degree and length of analgesia and sedation is dose
dependent. A dose of 5-10 µg /kg was found effective for sedation
and a dose of 20 µg /kg was effective for sedation and analgesia.
No recommended doses for butorphanol in
donkeys exist. Twelve
healthy male
donkeys were randomly divided into two groups. One
group received 10 µg/kg of detomidine while the other group
received 10 µg /kg of detomidine and 25 µg /kg of butorphanol.
Sedation was evaluated by a scoring system and characterised by
lowering of the head, relaxation of the upper eyelids,…

▼ Tese especialmente elaborada para obtenção do grau de Doutor em Ciências Veterinárias na Especialidade de Sanidade Animal
Em Portugal os equídeos apresentam um parasitismo caracterizado por cargas parasitárias e
biodiversidade helmíntica elevadas, fatores potencialmente muito patogénicos para os seus
hospedeiros. Considerando o reduzido efetivo de asininos existente no nosso país e a escassa
informação disponível sobre o seu parasitismo, foi considerado este estudo epidemiológico
com o objetivo geral de contribuir para o estudo e proteção do gado asinino em Portugal, e em
particular da Raça Asinina de Miranda no Planalto Mirandês. Assim, com este trabalho
pretendeu-se observar o estatuto parasitológico desta população de asininos de forma a
contribuir para um melhor conhecimento do parasitismo gastrointestinal envolvido, em
particular os estrongilídeos, e da adoção de medidas terapêuticas adequadas.
Considerando a realização de técnicas parasitárias adequadas para o estudo epidemiológico do
parasitismo gastrointestinal em equídeos, este trabalho pretendeu observar o nível de infeção e
biodiversidade parasitária no hospedeiro assim como observar a contaminação ambiental.
Durante cinco anos procedeu-se à monitorização de uma população de 62 asininos sujeitos ao
controlo seletivo, no solar da Raça Asinina de Miranda.
O estudo observou uma diminuição da taxa de prevalência média anual de infeção por
estrongilídeos gastrointestinais, de 35,1% para 23,0%, evidenciando uma distribuição do tipo
binominal negativa dos estrongilídeos parasitas de asininos sujeitos ao controlo antihelmíntico
seletivo. A taxa de prevalência de infeção foi superior nas fêmeas (39,5%), em
animais com idade inferior a quatro anos (46,7%) e com menor condição corporal (40,8%).
Ocorreu maior excreção de ovos nos jovens (901,6 OPG) e nas fêmeas (779,9 OPG) assim
como maior média da frequência de novas infeções nas fêmeas (6,9). Durante o estudo,
observou-se um número médio de desparasitações maior mas fêmeas (3,3) do que em machos
(2,7) e intervalos médios entre desparasitações de 16,2 meses (fêmeas) e de 22,4 meses
(machos).
Este estudo evidenciou o papel dos lameiros e da influência climática na epidemiologia da
estrongilidose asinina no Planalto Mirandês e permitiu observar a curva anual de excreção de
ovos de estrongilídeos parasitas de asininos desta região transmontana, verificando-se um
aumento progressivo de dezembro até junho, mês que se atinge um pico máximo na
eliminação de ovos, decrescendo depois progressivamente até dezembro.
Foi observada uma baixa biodiversidade de parasitas gastrointestinais, sendo Cyathostomum
sensu lato o género mais prevalente com ocorrência dos morfotipos A (35,0 a 85,7%) e D
(15,6 a 30,8%), C (15,7 a 15,2%), G (11,0 a 12,1%) e B (8,7 a 9,1%), E (2,2 a 1,5%), F (2,2 a
1,6%) e H (0,8%). Strongylus vulgaris (2,0%) foi o estrongilíneo mais observado.
Trichostrongylus axei (0,8%) e Parascaris sp. (0,8%) foram outros dos nematodes observados.
Em súmula, verificou-se uma elevada prevalência de parasitismo por…

▼ Existem poucos protocolos para a contenção e sedação de jumentos . Os agonistas alfa-2 são os fármacos mais amplamente administrados e é sabido que essa classe de fármacos pode produzir alguns efeitos deletérios no sistema cardiorrespiratório do animal. Os fármacos da classe dos opioides vêem ganhando espaço na prática anestésica com asininos, pois esses fármacos são utilizados como uma alternativa para a sedação desses animais. Além de produzirem certo grau de sedação, possuem característica analgésica, sem promover efeitos adversos. Na literatura pesquisada não foi encontrado, nenhum estudo sobre o uso associado de xilazina em infusão contínua com meperidina e seus efeitos hemodinâmicos nos muares. Diante deste exposto, objetivou-se estudar os efeitos da associação da infusão contínua da xilazina com bollus intramuscular de meperidina como protocolo de sedação em jumentos. Para tal, foram utilizados seis jumentos, SRD, sendo um macho e cinco fêmeas, com peso médio de 141±23 kg. Os animais foram submetidos a três protocolos experimentais dividos em três grupos, Grupo A: infusão contínua intravenosa de 1,1 mg/kg/hora de xilazina a solução salina por via intramuscular; Grupo B: infusão contínua intravenosa de 0,8 mg/kg/hora de xilazina e solução salina por via intramuscular e Grupo C: infusão contínua intravenosa de 0,8 mg/kg/hora de xilazina e 4 mg/kg de meperidina por via intramuscular. Foi observado redução na frequência respiratória, pressão arterial sistólica nos animais do grupo A e C, diminuição da pressão arterial diastólica e média em todos os grupos. Foi observada redução na altura da cabeça em todos os grupos. A associação da meperidina com xilazina em infusão contínua não provocou alterações cardiorrespiratórias significativas e produziu grau de sedação satisfatório
To the present, there has been few descriptions of anesthetic protocol for restraint and sedation in donkey (Equus asinus). Alpha-2-agonists are widely administered class of drugs. Known to produce some deleterious effects over the cardiopulmonary system. The use of opioids in donkeys has sained popularity anesthetic practicioners, since these drugs are used as an alternative sedative with analgesic characteristics with minimal side effects. To our knowledge, there has not been study evaluating the effects of the association of continuous rate infusion of xilazine with meperidine given intramuscularly over the cardiovascular parameters of donkeys. Therefore, the objective of our study evaluate was to the capacity of sedation and the cardiorespiratory implications of the anesthetic association in donkeys. In order to performe the study, six mixed breed, one male and five females, were used. The average weight has 141 ± 23 kg. The animals were subjected to three experimental protocols. Group A: Continuous intravenous infusion of 1.1 mg / kg / hour of xylazine and saline solution intramuscularly; Group B: Continuous intravenous infusion of 0.8 mg / kg / hour of xylazine and saline solution intramuscularly and Group C: continuous intravenous…

▼ Esta dissertação compreende quatro experimentos. Experimento1: Este estudo descreve algumas características do comportamento sexual de jumentos quando uma égua em estro foi usada para a coleta de sêmen. Foram usados neste estudo seis jumentos (J: 1, 2, 3, 4, 5, 6) da raça Pêga, com idade variando de 3,5 a 16 anos e pesando de 230 a 330 kg. Os animais foram previamente condicionados em um haras comercial de produção de muares localizado em Guaraciaba, Minas Gerais, Brasil. Para a colheita de sêmen, as éguas tiveram seu estro confirmado com o uso de um garanhão. As coletas foram realizadas com vagina artificial (modelo Botucatu), com água aquecida a 51C, pelo mesmo médico veterinário e preferencialmente distante de outros asininos. As coletas foram realizadas em intervalos de 48 a 72 horas, totalizando 180 coletas (17 a 40 coletas/reprodutor). Os parâmetros físicos e morfológicos do sêmen foram avaliados empregando-se um microscópio óptico comum, e a fração gel e a fração livre de gel foram mensuradas e avaliadas separadamente. Os dados de comportamento sexual foram analisados com uso do teste de KruskalWallis (P <0.05), com o Programa de Análises Estatísticas e Genéticas SAEG 9,1 (UFV, 2007). Os parâmetros seminais foram: motilidade total 84.2 6.0%, motilidade progressiva 74.5 7.1%, vigor 3.9 0.5, volume sêmen 47.3 28.7 mL e a fração gel de 71.7 54.8 mL. A fração gelatinosa esteve presente em 90 das 180 coletas, e para J1 39/40 (relação total de coletas), porém J4 e J5 não apresentaram essa fração. As características do comportamento sexual foram: tempo de reação 18.3 17.6 minutos; tempo de monta 5.1 3.5 segundos; time de ejaculação 25.4 7.7 segundos; número de montas sem ereção 1.1 1.3 e número de resposta de Flehmen 7.4 5.8. Os jumentos adultos (J1, J2, J3) apresentaram menor tempo de reação em relação aos demais e menor número de montas sem ereção. Não foram observadas diferenças significativas entre jumentos no seu comportamento (P>0.05),porém foi observada diferenças entre grupos quanto ao tempo de reação. Todas as coletas de sêmen foram iniciadas com investigação olfativa do genital externo das éguas. O tempo de ejaculação, resposta de Flehmen e montas sem ereção foram similares ao descrito em monta natural usando jumentas. Entretanto, não foi observado comportamento mastigatório exibido por alguns reprodutores na presença de jumentas. O uso de égua em estro para coleta de sêmen pode ser feito eficientemente sem afetar significativamente o comportamento sexual. Experimento 2: Este experimento foi conduzido com seis jumentos reprodutores da raça Pêga, com peso médio de 272 34,97 (231 326 kg), sendo subdivididos em adultos (J1, J2 e J3, 16,14 e 15 respectivamente) e jovens (J4, J5 e J6, média 3,5 anos). Os reprodutores apresentavam histórico de fertilidade normal à monta natural, e após realização de exame andrológico foram classificados como aptos à reprodução. Foram realizadas 180 coletas de sêmen, tendo os reprodutores apresentado parâmetros seminais considerados normais para a espécie. De agosto/2006 a…

▼ The aim of this study was to elucidate aspects of asinine behavior from the description of various collections using an artificial vagina and relate this behavior with the seminal parameters. We evaluated also the availability of the formulation of the diluent T2-94 plus dimethylformamide in the protection of sperm cells during cryopreservation of semen from the Pêga breed donkeys; examined the effect of the reintroduction of seminal plasma (SP) after thawing in protection against osmotic stress of that semen, and also the effect of dilution with Botu-Semen (BTU), evaluating the effects on parameters of sperm viability assessments by "in vitro", described in Chapter 2. Used in this study were three Pêga donkeys. At first, the samples were taken only for sexual behavior of animals: Number of Flehmen Reflexes (FR), numbers of mounts without erection (MWE) and reaction time (RT), besides the evaluation of fresh semen is not diluted. The results showed that the animals were, on average, FR 3.9, MWE 1.4 and finishing the service about 24.8 min. The mean ejaculate volume was 53 mL. The motility was 77%, and the force of 3.7 0.3. The sperm concentration ranged from 683 to 710 million sperm per mL of semen ejaculated. In morphology, the average was 12% of viable cells in the ejaculate. It was found that the greater the reaction time and the number of mounts without erection, the greater number of ejaculations in the presence of gel. The best adequacy of management to be employed under the conditions of the study, the proportion depends on knowledge about the sexual behavior of animals used. In a second step, semen was collected from those animals intended for freezing, using the diluent T2-94, plus the cryoprotectant dimethyl formamide. On thawing, the samples were diluted SP or BTU and observed for two hours, during the heat resistance test (HRT). Samples were removed for evaluation of frozen-thawed semen, the morphology and hypoosmotic stress test in three treatments (control, SP and BTU). The results showed that the motility was greater in SP treatment (55.9%) compared with the control group (50.6%). The mean of the spermatic was 3.4 with addition of SP and BTU after freezing. The number of cells reactive to supravital test, and the percentage of total defects observed in sperm morphology did not differ between treatments. In hypoosmotic test, the number of reactive cells was higher in treatment with the addition of PS (43.5%). During the HRT, motility was kept higher within 2 hours after thawing with addition of PS or with addition of BTU (25.2 10.6 and 23.4 13.1, respectively). The same occurred with the spermatic in T4 showed that 2.8 0.4 in the treatment with the addition of SP, and 2.4 0.6 with the addition of BTU. The evaluation means 94 + T2-dimethylformamide to asses semen were positive, showing be able to preserve sperm motility after cryopreservation. The reintroduction of SP showed improvement in semen parameters and remained seminal acceptable standard tests "in vitro".

▼ Animal breeding and therefore the progress of the livestock industry is closely related with the genetic variability of animal species. Thus, the loss of this variability may limit the unpredicted options for animal improvement. The study of diversity and genetic variability of donkeys can assist in the decision making about what populations should be included in a conservation program, when financial resources are scarce, avoiding the duplication of efforts in maintaining the samples. Similarly, the study of diversity can ensure that stocks of the same breed, which have particular characteristics, are not discarded during the conservation process. This work aimed to optimize the genotyping systems based on the fluorescent detection of microsatellite polymorphisms for donkeys with which will be analyzed the genetic variability within and between three donkey breeds raised in Brazil. With the use of microsatellite markers it was possible to assemble an efficient panel of markers for tests of exclusion of paternity. There were a total of 91 alleles for all studied loci. Estimates of allele frequencies of different microsatellite markers and indices of diversity reveal valuable information that will allow to monitor, maintain and genetically characterize donkey genetic resources. The Northeastern breed had the highest number of alleles, however the higher inbreeding estimate. The lowest rate of inbreeding was detected in the Brazilian breed. The highest genetic distances were observed between the Brazilian and the Northeastern breeds (0.2197), whereas the lowest distances were observed between the Pega and Northeastern donkeys (0.0868). By sequencing and analyzing 596bp of the control region of mitochondrial DNA it could be observed that with the exception of the Brazilian breed, the other breeds of xv donkeys studied have high nucleotide diversity. The donkey breeds from Brazil have haplotypes in common with Asian and European donkey breeds, originally from the somaliensis cluster. It was also observed the existence of a subdivision in the somaliensis cluster, suggesting either the existence of two distinct haplogroups or more centers of domestication.
O melhoramento genético e, por conseguinte, o progresso da pecuária está intimamente correlacionado com a variabilidade genética das espécies animais. Desta forma, a perda dessa variabilidade poderá restringir as opções, não previstas, para os trabalhos de melhoramento animal. O estudo da diversidade e da variabilidade genética da espécie asinina poderá auxiliar nas tomadas de decisão a respeito de quais populações devem ou não ser conservadas, quando os recursos são escassos, evitando a duplicação de esforços na manutenção das amostras. Da mesma forma, poderá ainda evitar que populações de uma mesma raça, que possuam características particulares, sejam descartadas durante o processo de conservação. Este trabalho teve como objetivo estimar a variabilidade genética, entre e dentro, de três raças asininas mais comuns no Brasil visando à obtenção de um panorama geral da…

▼ 24 serum constituents were dosed from 102 Brazilian donkeys, to compare with values obtained for other authors to other races of equines and to verify if the age and the sex influence in these values. Of the animals, 77 were male and 25 females; It had been also grouped by age: 0-6 months (38 animals), 7-12 months (29 animals), 13-18 months (28 animals) and more than 18 months (13 animals). After the dosages, were made the statistical analysis by the test of Tukey 5% and compared the values of the different groups. The majority of the values was in accordance with the results considered for other authors, few differences had been found. Statistical differences between males and females had been found, only for magnesium, GGT (gamma glutamiltransferase) and urea; however, in relation to the age, significant differences for the majority of the constituent had been found, mainly for the young, enclosed animals in the age band of 0 the 6 months. Amongst the 24 analyzed constituent, the only ones that they had not presented variations related to the age had been the urea and the ionized calcium. The results that were different from the other authors can be related to the race, ambient influences, amongst others. The values of the sanguine constituent had not been differed significantly between the sex; however, it is noticed that the age intervenes considerably with the values of total proteins, albumen, globulin, relation albumen: globulin, creatinine, urates, cholesterol, triglicéris, match, total calcium, relation calcium: match, Mg (magnesium), chlorides, sodium, potassium, AST (aspartate aminotransferase), ALT (alanine aminotransferase), GGT and CK (creatine kinase). The observed variations are given that they can serve of base for accomplishment of new research involving Brazilian donkeys and contribute for the creation of exclusive values of reference to this race.

▼ The objective of these studies was to develop near-infrared reflectance spectroscopy calibration equations from diet-fecal pair datasets to predict the diet quality and intake of
donkeys. One hundred-forty diet-fecal pair samples were generated from two independent in vivo feeding trials conducted in the United States (N = 100) and Africa (N = 40). At each site, ten female
donkeys were fed mixed diets blended from 25 forage and crop residues. The modified partial least square model (MPLS) was used to develop calibration equations for crude protein (CP), digestible organic matter (DOM), dry matter digestibility (DDM) and organic matter digestibility (OMD), for the US, Africa and US/Africa combined datasets, and dry matter (DM) and organic matter (OM) intake calibrations from the US datasets. Crude protein (CP) equations were developed with standard error of calibration (SEC) < 1.0 and coefficient of determination (R2) > 0.90, (SEL = 0.5). The US, US/Africa and Africa CP equations had SEC value of 0.77, 0.97 and 0.88 with corresponding R2 of 0.97, 0.95 and 0.88, respectively. Validation of the US CP equation resulted in a standard error of prediction (SEP) of 1.79 with corresponding coefficient of correlation (r2) of 0.82 and slope of 0.84 indicating high accuracy of prediction. In vivo derived DOM equations were also developed for the US, Africa and US/Africa datasets with SEC values of 2.58, 4.91 and 3.52, and R2 of 0.60, 0.81 and 0.84, respectively. In addition, the SEC and R2 values were 3.25 and 0.72 for US OMD, 3.28 and 0.79 for US DDM, and 4.2 and 0.85 for US/Africa OMD, and 4.3 and 0.87 for US/Africa DDM equation, respectively. Calibration equations for predicting DMI and OMI have resulted in SEC values of 3.45 and 3.21 (g/kgw0.75) and R2 values of 0.89 and 0.84, respectively. The present study explored the relationship between DMI and diet quality attributes. Crude protein and digestible organic matter to crude protein ration (DOM/CP) with r2 values of 0.60 and 0.39, respectively, have shown good correlations with intake. The present studies have confirmed the potential for the fecal NIRS profiling for predicting CP, DOM, DDM, OMD, DMI and OMI of
donkeys. Both calibration and validation results have indicated that the present donkey equations were comparable to previously developed equations for ruminants; they have the capability for accurate prediction of diet quality and intake, and can be a useful tool for monitoring the nutritional well-being of
donkeys with acceptable accuracy. Research works to further expand the present calibration equations with additional diet-fecal samples particularly from Africa that did not meet the required accuracy level is recommended.

▼ The present study was conducted with the aim of identifying the internal parasites in
donkeys in Kiambu District of Kenya, determining their seasonal prevalence, and elucidating
the pathological lesions associated with them.
For a period of one year ( from August 1994 - August 1995), donkeys of varying ages and
sexes were examined for parasites and pathological lesions. Age and the weight of each
donkey was recorded. Fecal samples for parasite egg counts were collected once a fortnight.
In total, 353 donkeys were considered.
Six mature donkeys of mixed sexes (two, during each of the months of April, June, and
August 1995), which had not been dewormed, were purchased from the study area. They
were kept indoors and fed on hay for 14 days. They were then starved for another three days
after which they were sacrificed. A full postmortem examination was conducted on each
animal and the various portions of the gut meticulously examined for parasites . The affected
organs were identified, the gross pathological lesions recorded and tissues for histopathology
taken and processed routinely.
In the determination of the degree of infestation, it was observed that there was a statistical
significance in the difference in egg per gram counts observed between the short dry season
I and the long rain one, the long rain season and the short rain one, the long dry season and the
short rain season, the long rain season and the long dry one as well as between the various
age groups. However, there were no differences in egg counts either between the short dry
season and the short rain one or between the sexes.
Several species of helminths were identified. These were, Dictyocaulus arnfieldi which were
encountered in 100% ( 6/6 ) of the necropsied donkeys, Strongylus vulgaris, Strongylus
edentatus in 100% of the donkeys, Cylicocyclus radiatus and Strongylus equinus in 83%
and 67% respectively, Triodontophorus serratus and Cyathostomum catinutum each in 50%
of the Donkeys, Cyathostomum coronatum, Paranoplocephala mamillana, Anoplocephala
perfoliata, Gasterophilus intestinalis and Anoplocephala perfoliata each encountered in
33% of the donkeys. Habronema muscae, Triodontophorus tenuicollis, Cylicocyclus
auriculature, Cretorestom acuticalator, Trichostrongylus axei, Cylicocyclus ultrasectum,
Trichonema tetracum, and Parascaris equorum, all appeared in 17% of the necropsied
donkeys.
All the six donkeys necropsied were unthrifty and had rough hair coats and the mucous
membranes were pale. There were nodules as well as small hemorrhages throughout the wall
of the intestines and an infiltration of lymphocytes, neutrophils and eosinophils in all the
donkeys. In some cases, adult tapeworm, Anoplocephala perfoliata, were attached to the
caecal mucosa whereas other adult worms (mainly Strongylus species) were collected from
the intestines.
The lungs, in all the necropsied donkeys, were oedematous and pale and were predominantly
infiltrated with leukocytes. The ,bronchioles as well as the bronchi contained mature…

▼ The veterinary anaesthetist is called upon to deal with a number of
species of animals which exhibit great variation in size and temperament as
well as in anatomical and physiological development. Apart from differing
response of each species to the various anaesthetic agents, there is often
marked variation in response between breeds within each particular species
(Hall and Clarke, 1983).
The sedative and anaesthetic effects of xylazine hydrochloride not only
show considerable variation from species to species but, the variation is also
exhibited among individual animals of the same species (Neophytou, 1982).
Although the use of xylazine hydrochloride and ketamine
hydrochloride independently or in combination in various animal species
has been reported (Lindley, 1980; Byagagaire, 1982; Mbiuki, 1982; Allen et al.,
1986; White et al. 1987) very- little has been reported about their use in
donkeys. This project was designed toevaluate the use of xylazine, ketamine
and atropine for general anaesthesia in donkeys.
A total of 30 experiments were carried out on 30 donkeys, 25 being
males and 5 females. They were aged between 2 to 11 years and weighed
between 80 and 200 kg. The donkeys were divided into 6 groups of 5 animals
each.
Anaesthetic trials were carried out using xylazine hydrochloride,
ketamine hydrochloride and atropine sulphate. Xylazine was used at a dosage
of 2.0mg/kg body weight, ketarnine at 4.4 mg/kg body weight and atropine at
a total dose of 25 mg. Atropine was injected subcutaneously, and the other
drugs intramuscularly.
(xii)
Anaesthetic times were recorded from the time the trial drug(s)
was/were injected until 2 hours were over. The anaesthetic parameters
monitored were weak time, recumbency time, down time, attempt to rise
time, standing time, unconsciousness time, muscle relaxation, reflexes, pain
sensation and other behavioural changes attributed to the injected drugfs).
The other physical parameters including the heart rate and respiratory
rate were recorded every 5 minutes during the experiment and the rectal
temperature every 15 minutes.
A jugular-blood sample for routine hematology was taken 10 minutes
before injection of the trial drugts), 1 hour and 5 hours after injection of the
trial drug(s). A great deal of variation in reaction to the drugs was seen
within groups and between groups.
The drug combinations achieved weak time earlier. Atropine-
Ketarnine-Xylazine combination achieved weak time in 5.20±1.30mins while
xylazine alone attained it in 10.00±2.12mins and ketamine alone in 6.00±1.58
mins. Ketamine alone and ketamine-xylaxine combinations made donkeys
go into recumbency. The drug combinations ketamine-xylazine and atropineketamine-
xylaxine made the donkeys stay in recumbency for 24.80±13.80
mins and 46.60±17.86mins respectively .. This was longer than for ketamine
alone and atropine-ketamine whose times were 18.80±9.41 and 10.00±11.55
mins respectively. Recovery was much faster in 'donkeys. injected with
ketamine alone (124.00±9.61 mins)…

▼ This study utilises a variety of research methods in order to investigate aspects often overlooked within Scottish film criticism, and indeed film studies more generally, namely: pre-production, production experiences, marketing and distribution, and reception. To date, Scottish film criticism has exhibited a preoccupation with questions of nation, national identity and national cinema, and overwhelmingly scholars have privileged almost exclusive analysis of the film text. Spurred by Jonathan Murray’s (2007, 2011, 2012) questioning of the continued relevance of the national framework, this thesis goes beyond the frame of the film text in order to consider new ways in which a national framework might be of relevance when analysing Scotland’s cinematic output. Concurrently, the chosen case study is also used as a means of critiquing existing literature on collective identity and national cinema.
As the title of this thesis suggests, analysis centres on the Dogma-inspired Advance Party initiative and its resulting films, Red Road (Arnold, 2006) and Donkeys (McKinnon, 2010). Devised by Glasgow-based Sigma Films and Denmark’s Zentropa, the cross border collaborative dimension of the Advance Party framework initially appears to challenge the appropriateness of the national framework. As this thesis demonstrates however, such a simplistic conclusion is reductive and overlooks the complexities of the film industry. Throughout this thesis, questions as to the intended and eventual function of the Advance Party framework arise, and these are revisited by means of the thesis Conclusion.
Subjects/Keywords: Scottish cinema; British cinema; production studies; film marketing; film finance; film reception; production experiences; Red Road; Donkeys; Advance Party; Motion pictures Scotland; Motion picture industry Scotland; Film critisism Scotland

▼ A raça Asinina de Miranda é uma raça autóctone portuguesa em vias de extinção que tem sido beneficiada pela evolução da área de cosmética em Portugal. Havendo interesse na sua conservação e caracterização, têm sido desenvolvidos diversos estudos sobre alguns aspectos reprodutivos carecendo de investigação na área de produção de leite.
A crescente demanda do mercado consumidor por produtos alimentares de alta qualidade estimula a utilização de novas tecnologias que garantam a segurança microbiológica na produção, que aumentem a vida útil dos alimentos, e que provoquem poucas alterações na qualidade sensorial e nutricional do produto final. A radiação ultravioleta foi recentemente considerada como um novo tratamento não térmico para o tratamento do leite.
O objetivo deste estudo foi analisar o efeito da radiação ultravioleta nos microrganismos aeróbios totais no leite da raça Asinina de Miranda, proporcionando uma reflexão sobre a possibilidade da sua utilização por empresas do sector.
Os resultados obtidos permitiram concluir que a radiação ultravioleta é uma tecnologia eficiente na redução do valor microbiano do leite que pode ser utilizada como alternativa aos tratamentos térmicos tradicionais, ou ser usada em associação com estes, dependendo do destino final do leite.
The Asinina de Miranda breed is a Portuguese autochthonous breed that is undergoing extinction and has been benefited by the evolution of the cosmetic production in Portugal. In the interest of its conservation and characterization, several studies have been developed on some reproductive aspects however there is a lack of research regarding the milk production.
The increasing consumer demand for high quality food products stimulates the use of new technologies that ensure microbiological safety in the production process, increase the shelf life of food products and cause reduced changes in the sensory and nutritional quality of the final product. Ultraviolet radiation was recently considered as a new non-thermal treatment for the treatment of milk.
The objective of the current study was to analyze the effect of ultraviolet radiation on the total aerobic microorganisms in Asinina de Miranda’s milk, providing a reflection on the possibility of its use by companies in the sector.
The results obtained allowed us to conclude that ultraviolet radiation is an efficient technology in reducing the microbial value of milk that can be used as an alternative to traditional thermal treatments or be used in association depending on the final destination of the milk.

▼ A Naturasin® é uma empresa que comercializa cosméticos provenientes de leite
de burra. O seu efectivo é constituído pela Raça Asinina de Miranda, em que o seu efectivo
é reduzido em Portugal.
Considerando o maneio que esta empresa efectua no seu efectivo, estudou-se qual
a eficácia dos desparasitantes doramectina em regime extensivo e eprinomectina em regime
semi-intensivo em parasitas gastrointestinais.
Durante 5 meses efectuaram-se recolhas de fezes para estudos parasitológicos
com a aplicação das técnicas de McMaster modificada, Willis, sedimentação e coprocultura.
O efectivo estudado era composto por 18 burras das quais 11 estavam em regime extensivo
e desparasitadas com doramectina, grupo D1 e 8 em regime semi-intensivo e
desparasitadas com eprinomectina, grupo D2.
O estudo observou uma diminuição de 66 vezes o OPG no grupo das burras D1,
sendo comprovada a eficácia da doramectina neste grupo em regime extensivo. No grupo
das burras aleitantes D2, a diminuição do OPG após aplicação da eprinomectina foi de
apenas 1,2 vezes, comprovando a não eficácia deste desparasitante neste grupo. Foi
observada uma prevalência de 100% de Cyathostomum nas coproculturas.
Conclui-se a elevada prevalência de Cyathostomum em asininos associados a estes
desparasitantes com os respectivos regimes. Recomenda-se mais estudos nesta área.
Naturasin® is a company that sells cosmetics derived from donkey's milk. Its cash is
made up of the Race Assina de Miranda, in which its cash is reduced in Portugal.
Considering the management that this company does in its herd, we studied the
efficacy of desparasitizer, doramectin in an extensive regimen and eprinomectin in a semiintensive
regimen in grastaintestins parasites.
In 5 months, stool samples were collected for parasitological studies with the
application of the modified McMaster, Willis test, sedimentation and coproculture techniques.
The studied population consisted in 18 donkeys, of which 11 were in extensive regimen and
dewormed with doramectin, group D1 and 8 in semi-intensive regime and dewormed with
eprinomectin, group D2.
The study observed a 66-fold decrease in OPG in the D1 donkey group, and the
efficacy of doramectin in this extensive group was demonstrated. In the group of D2 motile
dams, the decrease in OPG after application of eprinomectin was only 1,2 fold,
demonstrating the non-efficacy of this deparasite in this semi-intensive group. A prevalence
of 100% of Cyathostomum in coprocultures was observed.
The high prevalence of Cyathostomum in asinines associated with these dewormer
with the respective regimens is connived. Further studies in this area are recommended.

▼ The forces exerted by a rider on a horse have a direct influence on the mechanical load experienced by the horse and consequently on its motion pattern. The aim of this thesis is to explore the biomechanical interaction between rider, saddle and horse in order to get insight in the loading of the horse and to identify potential opportunities to reduce load-related injuries. The influence of man on the horse is mediated trough tack, which functions as an interface between the horse and the human being(s) using it. The tack is often connected to both horse and rider and is therefore well-positioned to incorporate measuring devices that can record the forces between horse and rider. So-called saddle-pressure measuring devices have been used to evaluate saddle-fit and could also be a useful tool to study the interaction between horse and rider. However, not much was known thus far about the validity, reliability and usability of these devices for this purpose. Therefore, the first studies in this thesis focussed on this topic. The FSA system was only reliable in highly standardised circumstances. The Pliance system provided reliable and repeatable results and can be used indeed to study the interaction between horse and rider. In this thesis it was used to evaluate the effect of rider position on the force distribution beneath the saddle and to study the signals given by the rider to the horse performing lateral movements in dressage. One of the important physical properties of the rider that influences the horse is the rider’s weight. The effect of tack and weight on the movements of the horse was therefore studied. The introduction of a mass with considerable weight on the horse’s back induced an overall extension that might contribute to back injuries. During trot, the rider can either rise from the saddle during every stride (rising trot), or remain seated (sitting trot). The back movement during rising trot showed characteristics of both sitting trot and the unloaded condition, with a higher degree of extension during the sitting phase and less extension in the standing phase. In the standing phase peak force on the stirrups is higher, but the overall vertical peak force on the back of the horse is less. This supports the general assumption that rising trot is less demanding for the horse than sitting trot. Three spring-(damper-)mass models were constructed to evaluate the biomechanical requirements the rider has to comply with during sitting trot, when using the modern riding technique adopted by jockeys during racing, and in rising trot. The models demonstrate which combinations of rider mass, spring stiffness and damping coefficient will result in these riding modes. Optimization to minimize the peak force of the rider and to minimize the work of the horse resulted in an “extreme” modern jockey technique, which is not adopted by actual riders. The incorporation of an active spring system for the leg of the rider, was needed to simulate the rising trot. The general…

▼ The evolution of the horse in America and Europe was discussed, and the author's ideas on the origin of the present draught horses in Holland and Belgium were presented on the basis of measurements by him and others on excavated skulls. In the older layers of the mounds ('terpen') in Friesland horse skulls were of the slender Oriental type, probably akin to Equus Przewalski, introduced by the northern streams of the Celts, and probably identical with the Helvetian-Gallic horse. In more recent layers remains were of the heavier Eq. robustus , probably introduced by the Teutons during the tribal migrations. Finds from still more recent layers indicate that these two types were crossed, probably giving rise also to the Friesian horse. In Belgium the two types seemed to have occurred also first separately. There they became mixed before the Christian era. During the great tribal migrations the Teutons again introduced an Eq. robustus -type to Belgium causing new mixing, but possibly less in the Ardennes. This could explain the more slender Ardennes horse and the heavier Brabançons, which were spreading further in Belgium. Dutch Draft horse breeding was much improved by the large quantity of first- class breeding material, transferred for safety from Belgium during the First World War. The blood line of Indigène du Fosteau had played a very important role.

▼ Genetic variation contributing to the phenotypic variation was utilized in this thesis to understand the genetic background of a complex trait IBH, and to understand genetic diversity and relationships between various horse populations. IBH is the most common skin allergic disorder in horses, caused by bites of midges, predominantly
Culicoides species. It affects various horse breeds worldwide. With no effective treatment, IBH degrades horse health and causes economic loss. In this thesis, we used genome-wide SNPs to identify regions contributing to genetic variance of IBH susceptibility. We also investigated influence of increased number of horses and dense SNPs on identification of genomic regions associated to IBH susceptibility. Multiple genomic regions with small effects were observed in Studies I-III. Interesting genomic regions in the Icelandic horse population across the studies I and II, was observed on chromosomes 1, 7, 10, 15 and 17. The percentage of the genetic variance explained by top ten windows increased from 3.07% (Study I) to 6.56% (Study II). Novel genomic regions were identified when number of Icelandic horses was increased in Study II. Using dense SNPs on the Exmoor pony population we identified novel genomic regions, on chr 8, associated to IBH susceptibility, though with borderline significance. In Study IV, pre-conceived understanding about evolutionary history of horse populations matched obtained results from investigation of genetic relationships within Dutch warmblood populations (pairwise mean FST ≤ 0.070), and within pony-like populations (pairwise mean FST ≤ 0.078). Horse populations with similar genetic background might share similar genetic components for IBH susceptibility. The Friesian horse population had lowest diversity (mean inbreeding coefficients: <em>fi</em>: 30.4%, <em>fi</em>ROH= 22.2%) in Study IV and was genetically distinct (FST ranged from 0.13 to 0.17). This might be a result of a history of several population bottlenecks and selection on a closed breeding scheme. Low diversity in immunity related genes, observed in the Friesian horse population, might have led to increased prevalence of IBH. Similarly, low susceptibility of IBH in a warmblood population, KWPN sport horse population might be due to high genetic diversity ( =-6.9%). High genetic diversity in KWPN sport horse population might be a result of an open breeding scheme and interbreeding with other warmblood populations.

▼ AInsect Bite Hypersensitivity (IBH) is the most common skin allergy in horses and involves a Type I (IgE mediated) hypersensitivity reaction against bites of insects, mainly of the
Culicoides species. Welfare of affected horses is seriously reduced and no fully curative treatment is yet available. Furthermore, current diagnostic tests are unreliable because of their low sensitivity and specificity. Aim of our research was to increase the understanding of immunological aspects of IBH, with special attention to improving diagnosis by the characterization and production of recombinant allergens. Whole body extracts (WBE) of three
Culicoides species:
C. obsoletus C. nubeculosus and
C. sonorensis were evaluated for their applicability for diagnosis of IBH in horses in The Netherlands. They were tested for IgE binding by ELISA and Western blotting and for their capacity to degranulate basophils in a histamine release test. For all tests, best results were obtained with
C. obsoletus. The ELISA was further evaluated using
C. obsoletus extract on approximately 200 IBH affected and healthy horses, which demonstrated high test sensitivity and specificity.
C. obsoletus-specific IgE serum levels were found to be the same in the IBH season and off season, suggesting that the test can be used to diagnose horses in winter when clincial symptoms are absent. Since
C. obsoletus was found to be the most important species for diagnosis of IBH in The Netherlands, mRNA of this
Culicoides species was sequenced and assembled to create a transcriptome. Using the sequences from in literature described allergens from
C. nubeculosus and
C. sonorensis, similarity searches were performed on this transcriptome,. This resulted in the identification of seven allergens from
C. obsoletus. These allergens were cloned and expressed as recombinant proteins in
E. coli and named Cul o 1 – Cul o 7. The frequency of positive test results by ELISA within IBH affected horses ranged from 38 % to 67 %. The capability of the allergens to induce Type I hypersensitivity reaction in IBH affected horses was demonstrated by an intradermal test. The applicability of the 7
C. obsoletus derived recombinant allergens was further evaluated and compared with
C. obsoletus WBE in an IgE ELISA using a large number of horses.The highest test accuracy was obtained with WBE, followed by Cul o 2, 3 and 5. Two ELISA’s with a combination of recombinant allergens, combi-1 (Cul o 3, 5 and 7) and combi-2 (Cul o 1, 2, 5 and 7) were additionally performed and both resulted in high test accuracies close to that obtained with WBE. Both combi-1 and combi-2 resulted in a lower test sensitivity with samples collected in winter compared to samples collected in IBH season, but most IBH affected horses could still also be correctly diagnosed in winter. The association between several factors and IgE levels against <em>C.…

▼ Summary The general goal of this thesis was to provide information useful for the breeding programme of the Royal Dutch Warmblood Studbook (KWPN) in relation with the ongoing specialisation of the population. Data provided by KWPN consisted of records from studbook-first inspection, competition performance on dressage and show-jumping, and pedigree information. Firstly, the effect of specialisation was studied on the connectedness between the subpopulations of dressage and show-jumping horses, using the pedigree information. Results indicated that relatedness between horses in the two subpopulations has been reduced to a low level, while relatedness within both subpopulations has been increasing consistently. A reduction in the number of influential ancestors in both subpopulations was observed. Secondly, it was analysed whether the specialisation for either dressage or show jumping has affected genetic parameters of traits recorded in the two subpopulations. Traits recorded at studbook-entry inspection were defined as a dressage trait or a show-jumping trait according to the type of horse that received the inspection. Bivariate analyses were performed to estimate the genetic correlation between the two traits. Results indicated that the specialisation process has resulted in a difference in mean trait values between dressage and show-jumping horses. However, differences in heritabilities for traits defined as dressage or show-jumping did not differ significantly, and the genetic correlations between them were not different from one considering their posterior standard deviation. Thirdly, the model to analyse performance in competition of dressage and show-jumping was studied. Results showed that performance in competition for dressage and show-jumping is a heritable trait (h2 ~ 0.11-0.13), and that it is important to account for the effect of rider in the genetic analysis. Fourthly, it was estimated the genetic correlation between the performance of horses in dressage and show-jumping competition, and the genetic correlations between traits measured early in life and performance in competition in each of the disciplines. Results showed that the genetic correlation between performance of horses in dressage and show-jumping was slightly unfavourable (-0.12). The genetic correlation between dressage and show-jumping tended to become more unfavourable over time, but this trend was not reflected in changes in the correlations between competition traits and traits recorded in the studbook-entry inspection. From this study it can be concluded that no extra benefit is to be expected from definition of a combined breeding goal. However, entirely separated breeding programmes for both disciplines are therefore not advisable. Constructing separate selection indexes would allow for optimal weighting of information sources such as studbook-entry inspection traits in accordance to the breeding goal of each sports discipline.

▼ The aims of this study were 1) to determine the role of test results of young horses in selection for sport performance, 2) to assess the genetic diversity of a closed horse breed and 3) the consequences of inbreeding for male reproduction. The study was performed using existing databases containing records collected on young horses during inspections, which were linked to databases containing records on sport performance. Multivariate animal models were applied in estimation of genetic parameters. Heritability estimates of movement and free-jumping traits collected at Studbook Entry and at First Stallion Inspection were moderate to high. Free-jumping traits collected at both inspections showed high to very high positive genetic correlations to show-jumping in competition. Movement traits collected at both inspections showed favourably genetic correlations to dressage in competition. Subsequently, the effect of limb and foot conformation, in particular the trait uneven feet, as assessed at Studbook Entry Inspection on performance and length of sport career have been analysed. Limb and foot conformation had only weak to moderate genetic correlation to sport performance. Some foot conformation traits could be identified as risk factors for early retirement from sports; e.g. occurrence of uneven feet shortened the competitive life at elite level of jumping. The development of genetic diversity in a closed breed have been studied using the pedigree structure of the Friesian horse breed. Considerable loss of genetic diversity have taken place during the history of the studbook, corresponding to an average inbreeding rate of 1.3% per generation. Loss of genetic diversity was mainly due to drift from small effective population size during several generations. In a subsequent analysis the relation of inbreeding with semen quality of young Friesian stallions was investigated. It was concluded that low semen quality in Friesian stallions could not be attributed to inbreeding. Heritability estimates for semen quality traits were moderate to high and had substantial variation. Selection can be used to improve semen quality. Finally, opportunities for improvement of the breeding program have been discussed. Selection potentials are calculated to gain insight in the relative importance of each of the young horse tests to the breeding program. Additional opportunities to increase selection response have been discussed.

▼ Insect bite hypersensitivity (IBH) is the most common allergic skin disease in horses and is caused by bites of
Culicoides spp. IBH reduces welfare of affected horses and at present no effective preventive measure or cure exists. Aim of our research was to increase knowledge of the genetic background of IBH in horse populations and to explore opportunities to reduce IBH prevalence through selection and breeding. Data on Shetland pony and Friesian horse mares were gathered at obligatory inspections. IBH prevalence was 7.5% in Shetland pony mares and 18.2% in Friesian horse mares. Data were analyzed to identify risk factors. Combined effect of month and year of IBH scoring, region within the Netherlands and inspector were associated with IBH in both breeds. IBH prevalence significantly differed with coat colour and withers height category in Shetland pony mares. Moreover, prevalence was higher in Shetland pony mares with high body condition score (9.4%). Quantitative genetic analyses revealed substantial genetic variation for IBH in both breeds. Heritability on the observed scale and on the underlying scale was 0.08 and 0.24 respectively in Shetland pony mares, 0.07 and 0.16 respectively in Friesian horse mares. Therefore, IBH is a heritable phenotype in both breeds. Repeatability was 0.30 in Shetland pony mares and 0.89 in Friesian horse mares. Maternal effect (0.17) was estimated in Friesian horse mares only. To identify genomic regions contributing to the genetic variance, Shetland pony mares and Icelandic horses were selected according to a matched case-control design. Odds ratios of allele substitution effects of the unfavourable allele were between 1.94 and 5.95. Also, 13 and 28% of genetic variance was explained by all SNPs in respectively Shetland pony mares and Icelandic horses. Significant associated genomic regions across breeds suggest interesting candidate regions on ECA3, 7, 11, 20 and 23 contributing to genetic variance. Results support that ELA class II region on ECA20 is involved in IBH etiology, although follow-up studies are needed to confirm this and to identify genes in the other regions. The general discussion explored possibilities to reduce IBH prevalence through breeding and discussed implications of using clinical symptoms or diagnostic test results. Simulated selection was based on EBV, which included own performance, progeny performance or genomic data. Selection on IBH clinical symptoms should be based on testing at least 10 but preferably more progeny, accompanying strict selection in sires to achieve reasonable genetic gain. Expected genetic gain per year in genomic selection outperformed other strategies, although implementation of genomic selection requires a considerable investment in a reference population. A diagnostic test for IBH (yet unfeasible to perform on a large sample) has the potential to increase genetic gain
