▼ The impact of reduced mobility score on the fertility was assessed in 130 cows on a split-calving pasture-based New Zealand farm. For this research the 130 cow autumn-calving herd was analyzed. The breeding season of 9 weeks consisted of 6 weeks AI followed by 3 weeks of natural mating. Forty cows had a locomotion score (LCS) of 2 or 3 for more than 2 times during the prebreeding period. Nineteen of these cows did not get pregnant in the breeding season.
There was found a significant relation between average LCS and not getting pregnant in the breeding season and there was found also a significant relation between more than 2 times LCS 2 or 3 during the prebreeding period and not getting pregnant in the breeding season. There was found no significant relation between more than 4 times LCS 2 or 3 during the prebreeding period and not getting pregnant in the breeding season.

▼ Lameness is one of the three most important causes of
economic loss inwestern European and North American dairy farms (Weaver,
1986). The current trend towards intensive dairy farming and the
importation of exotic breeds of cattle in Kenya's small-scale farms may
be accompanied by similar lameness problems. Since these small-scale
farms are collectively the largest dairy producers inthe country (Stotz,
1983), dairy cattle lameness would result in a significant reduction in
the national dairy output. A prospective study was therefore carried out
to estimate the incidence and to investigate the risk factors of dairy
cattle lameness in these farms.
One hundred farms were selected at random from the registers of
three Dairy Societies. Out of these, 78 participated in the study. The
farms were visited twice; first in March and then in June, 1993. During
the farm visits, all cattle in the farm were examined for clinical
lameness and digital lesions. Data on housing, management, nutrition and
signalment of cattle were collected through questionnaires administered
during the visits.
Farm, individual animal, and digit factors were assessed for their
association with lameness using logistic regression. The housing system
and the type and condition of the floor were considered at herd level;
while age, breed, heart girth, parity, reproductive status and stage of
lactation were considered at the individual animal level. The site (fore
or hind; left or right; medial or lateral) and conformation of the digits
were considered at the digit level.
The incidence of lameness during March to June 1993 was estimated
at 1.46% per month. The incidence increased with increased confinement
of cattle. It was 0.76% per month in cattle kept in pasture 24 hours a
day, 1.46% in cattle kept in pastures during daytime and 2.14% in those
housed 24 hours a day.
Interdigital cleft lesions (wounds, necrobacillosis, fibromas and
dermatitis) had the highest incidence (4.54%) followed by heel erosion
(4.43%) and loss of solear concavity (flat soles, 1.63%). Interdigital
lesions (wounds and necrobacillosis) comprised 51.5% of clinical lameness
cases while hoof overgrowth comprised 15.2%. Other, less frequent types
of clinical lameness were sandcracks (6%), digital sepsis (6%) and sole
ulcers (3%). Hind limbs were involved in 63.6% while fore limbs were
involved in 18.2% of the clinically lame cattle. However, all the digits
were simultaneously affected with heel erosion in 91.9%, flat sole in
70.0% and hoof overgrowth in 46.7% of the affected cattle.
Variance component analysis indicated that variation between
individuals was relatively more important in explaining the occurrence
of lameness (Variance component = 88.5%) than that between herds. In the
logistic regression models, confinement 24 hours a day (OR = 2.9; P =
0.0157), the Jersey breed (OR = 5.2; P = 0.0087) and the early lactation
period (OR = 5.9; P = 0.0421) were associated with clinical lameness.
Increasing length of the dorsal hoof wall, which was…

▼ In current literature, there is a limited amount of
large scale data available demonstrating
lameness morbidity in beef
cattle feedlots, the subsequent outcomes of individuals exhibiting
lameness, the morbidity and mortality of various
lameness
diagnoses, or the effect of locomotion score at the time of first
morbidity and its effect on outcome. In addition, current
perceptions of
lameness by feedlot industry participants are not
known and a reliable locomotion scoring system fit for use in a
feedlot setting has not been developed. Consequently, the
objectives of this research were three-fold. First, to obtain a
baseline of the perception of
lameness within the feedlot industry.
Second, to develop a functional locomotion scoring system for use
in feedlots and to test a training program implementing this
locomotion scoring system for inter-rater reliability. Third,
determine the association of
lameness diagnosis and locomotion
score at time of initial
lameness diagnosis with case outcome in
feedlot cattle and provide beef cattle feedlot
lameness morbidity,
mortality, and realizer incidence rates due to different
lameness
etiologies in a large scale, multisite study. One hundred
forty-seven consulting nutritionists, veterinarians, and feedlot
managers participated in the feedlot cattle
lameness survey. The
median response of estimated
lameness incidence in the feedyard was
2%, with a mode of 1% and a mean of 3.8%. Participants indicated
that footrot, injury, and toe abscesses were the most common causes
of
lameness.
A locomotion scoring system was developed to
clinically assess locomotion of beef cattle. The scoring system
consisted of 4 categories: normal movement (0), slightly affected
gait (1), obviously shortened stride or bobbing of head (2), and
reluctance to move or apply weight to the limb while walking or
standing (3). A total of 50 commercial feedlot employees and
agricultural students were trained to use the scoring system in
either English or Spanish. The scoring system was tested for
inter-rater agreement and rater agreement against a cooperative
standard based on consensus score by a team of individuals involved
in the development of the scoring system, which included beef
cattle veterinarians and welfare experts. Intra-class correlation
coefficient (ICC) and Fleiss’s kappa were used to evaluate
inter-rater agreement and rater agreement against the cooperative
standard. Inter-rater agreement using ICC was 0.85 (95% CI; 0.75 to
0.93) while the mean kappa value was 0.52 (moderate agreement).
Rater agreement with the cooperative standard resulted in mean
kappa value of 0.64 (substantial agreement). A dynamic population
longitudinal study with an initial study population of 245,494 head
of feedlot cattle, with 524,780 animal arrivals and 527,220 animal
departures recorded over the 12-month study was conducted over a
year by trained personnel in six participating feedlots located in
Kansas and Nebraska.
Lameness morbidity incidence was 1.04 cases
per 100 animal-years;
lameness mortality was 0.397 cases per…

▼ Objective – To identify quantifiable kinematical parameters that give an objective image of degree of
lameness in horses after induced
lameness of the tarso-crural joint with LPS and to test the effectiveness of an intra-articular administered opioid morphine.
Study design – Randomized, blinded cross-over clinical study
Animals – 8 clinically sound Dutch warm blood mares
Procedure –
Lameness was induced with an intra-articular (IA) injection of lipopolysaccharide (LPS). One hour after LPS injection the horses were treated with an IA injection of morphine (MOR) 120 mg diluted with NaCl to a solution of 20 ml or with 20 ml saline (SAL) as control. The horses had to walk and trot on a treadmill and kinematic measurements were made before and 4, 8 and 28 hours after LPS induced
lameness. Kinematic measurements were made of the hoof, fetlock joint, tarsal joint, stifle joint, trochanter major (hip joint), tuber coxae and sacrum.
Lameness was subjectively scored by an orthopaedic using a scale of the standard American Association of Equine Practitioners. Data are reported as mean ± SEM and were analyzed using SPSS. Differences were considered significant at P < 0,05.
Results – After
lameness induction the range of motion of the tarsal and fetlock joint significantly decreased in the control group and after IA administration of morphine the range of motion of the fetlock joint and the tarsal joint significant increased and returned to baseline levels. Significant compensatory effects were only seen in symmetry indices of the range of motion of the contralateral hind limb of the tarsal joint at walk. Fetlock joint extension at walk was decreased up to 28 hours after
lameness induction. Subjective clinical
lameness score showed a significant increase in
lameness grade after LPS injection in the control group. A decrease in
lameness grade after IA injection of morphine was seen at 4 and 8 hours after
lameness induction in clinical
lameness scores. Subjective clinical
lameness score showed all horses to be sound at 28 hours after
lameness induction with LPS.
Conclusions and Clinical Relevance - Morphine had a strong clinical analgesic effect. The analgesic effect of IA morphine was seen in objective kinematical parameters as well. No systemic side effects could be detected after IA administered morphine. Subtle or slight
lameness could be detected in some of the objective kinematical parameters up to 28 hours after
lameness induction. In contrast, subjective
lameness scoring showed all horses to be sound at 28 hours after
lameness induction.

▼ The objective of this study was to determine the effects of pen flooring-type in front of the feed-bunk, the slipperiness and the flooring-type in the holding pen on gait of Alberta free-stall housed dairy cattle. Fifty-one dairy farms with at least 70 Holstein milking cows and no access to pasture were selected from a list provided by the hoof trimmers from the Alberta Hoof Health Project. On these farms slipperiness and flooring type in the feeding alley and in the holding pen was recorded. Forty focal cows were gait scored (limping, head bob, asymmetric steps and tracking-up). In order to calculate odds ratios, farms were divided in groups: Farms with < 15% of lame cows and farms with ≥ 15% lame cows. Farms with < 25% asymmetric cows and farms with ≥ 25% asymmetric cows. Farms with <60% under-tracking cows and farms with ≥ 60% under-tracking cows. Because of the small number of farms with other flooring than grooved concrete in the feeding area of the pen and in the holding pen, odds ratios could not be calculated. Slipperiness did not have a significant effect on gait of dairy cows.

▼ Lameness continues to cause significant problems in profitability, productivity, and animal welfare in the feedlot industry. Toe tip necrosis syndrome (TTNS) is a new name for a previously reported condition. By definition, TTNS is separation of the apical white line with tissue necrosis and clinical
lameness. This definition includes complications such as pedal (P3) osteitis, middle (P2) and proximal (P1) phalangeal osteomyelitis, tendonitis, tenosynovitis, cellulitis, and embolic pneumonia. Anecdotal experiences from practitioners report this
lameness in feedlot cattle will develop within weeks after feedlot entry. Often the hindlimbs, specifically the lateral claw, are affected where a separation of the dorsal wall and sole will be noticed. Secondary infections will progress deeper into the foot and become systemic. Unfortunately, despite treatment, these animals can become very lame and will need to be euthanized. The overall objective of this project was to describe the epidemiology of TTNS in western Canadian feedlot cattle. The specific objectives were 1) to use clinical examinations, imaging modalities, and necropsy findings to aid in description, classification, and characterization of TTNS lesions, 2) to describe the epidemiology of TTNS in feedlot cattle, and 3) to evaluate risk factors for TTNS.
Upon further investigation into this arrival related condition it became apparent that there were many different descriptors: P3 necrosis, toe abscess, apicus necrotica, apical pedal bone necrosis or toe necrosis. These names and descriptors of toe tip lesions were based on anecdotal experiences and previous case reports. As a result, traditional epidemiological approaches that included field investigations, clinical and necropsy examinations were implemented to identify, characterize and describe this condition. Based on clinical findings, imaging modalities, and necropsy specimens examined during September to December 2012, inclusive, a more specific name and descriptive case definition were introduced.
TTNS descriptive epidemiology was described by use of a retrospective database analysis from Feedlot Health Management Services (FHMS) with 702 veterinarian confirmed TTNS cases by necropsy examination. From this database, there were 30% (210/702) of necropsy cases treated for TTNS and 70% of cases (492/702) that were not treated. Of those animals treated, the mean and standard deviation (median) interval from feedlot arrival to first treatment was 18.9 ±1.7 d (12 d). The mean (standard deviation) days on feed until death from TTNS was the earliest in grass-fed calves (32.4 ± 22.1 d), followed by auction-derived (40.6 ± 40.6 d), ranch direct (44.1 ± 53.1 d), and back-grounded calves (69.0 ± 75.6 d) (P < 0.001). Yearlings were on feed for a mean (standard deviation) days of 37.1 ± 32.0 d when compared to calves at 49.5 ± 57.0 d before death (P < 0.001). The greatest proportion of deaths occurred from September to November. There were 96.2% (1,832/1,904) of lots without one case of TTNS and 3.8% (72/1,904) of lots…

▼ Lameness can be a cause of negative economic output in sheep farming owing to its
adverse effects on productivity, reproductive performance and poor growth performance
in lambs. The extent of lameness in sheep and its associated predisposing causes in
Kenyan sheep rearing systems has not been elucidated. This study was carried out in
sheep under free-range grazing system in Kajiado District, Kenya, from March 2010 to
June 2010 with the following objectives (1) to determine the prevalence of conditions
causing lameness, (2) to determine the possible risk factors predisposing the sheep to
lameness conditions.
This was a cross-sectional study in which each farm was visited several times, but each
sheep on the farm was examined only once. Ten study farms were purposively selected
from three divisions of Kajiado District, based on the willingness of the farmers to allow
examination of their sheep and also on the stability of the farm's grazing routine from
more nomadic tendencies. The data was collected either by filling a formal questionnaire
with answers given through interviewing the farmers, farm managers or stockmen on
animal-level factors, or by recording observations made on the farm regarding farm-level
factors. The 10 farms had a total of 1916 sheep that met the study criteria. Out of these,
117 sheep were identified as lame during general locomotion scoring as they walked on a
flat firm part of the ground. Each of these 117 sheep were examined closely for specific
conditions or disorders causing lameness. Information on the actual disorders causing
lameness was recorded. The location of the disorders on the limb, affected limbs whether
fore or hind, and the affected claws whether lateral or medial were recorded in data collection sheets. The lesions causing lameness were photographed. A mark was put on
each examined sheep to avoid repeat examination.
Overall prevalence of lameness was 6.1 % (117/1916), out of which the conditions with
relatively higher percentages of occurrence were sole erosion (3.8%, 72/1916),
overgrown claws (3.2%, 61/1916) and tick-bite dermatitis (1.6%, 30/1916). Infective
conditions such as foot rot and interdigital dermatitis had prevalence of less than 1%. The
rest of the conditions such as shelly hoof, soil-balling, over-trimming and bone problems
were incidental findings each in a single sheep. The conditions causing lameness
occurred on the foot in 94% (110/117) of the lame sheep and on proximal parts of the
limb in 6% (7/117) of the cases. The distribution of the conditions among the lame sheep
was 43.6% (51/117) on the hind limbs, 23.1 % (27/117) on the forelimbs and 33.3%
(39/117) affected both hind and fore limbs.
Although there were several animal-level factors evaluated, the only factors found to be
significantly associated with higher locomotion score were the number of limbs with
lesions (X2 =11.15, P = 0.004), the affected limbs whether fore or hind (X2 = 9.20, P =
0.010), the affected claw whether medial or lateral (X2 = 16.98, P = 0.05)…

▼ Sow lameness is a production disease affecting not only animal welfare but also swine profitability. Second to reproductive problems, lameness is a major cause for premature sow culling in the swine industry (Anil et al., 2005). It has been estimated that 32% of sows culled for lameness have only produced one litter (Boyle et al., 1998). Lameness has been estimated to cost the United States swine industry approximately $23 million/year (Butters-Johnson et al, 2011).
The overall goal of this thesis was to validate diagnostic tools using a naturally occurring sow lameness model. This work was completed through four objectives: 1) to determine if behavior assessments, mechanical nociceptive threshold testing and walking and standing lameness scoring could identify a lame sow, 2) to determine if behavior assessments, mechanical nociceptive threshold testing and walking and standing lameness scoring were affected by the body system suspected to be contributing to the lameness identified using the Swine Lameness Diagnostic Manual, 3) to determine lameness etiology within the suspected body system as guided by the Lameness Diagnostic Manual, 4) to evaluate the accuracy of the suspected lameness etiology using the results of the Swine Lameness Diagnostic Manual, standing lameness scoring, locomotion lameness scoring and swine veterinarian expertise.
The results of this thesis identified that the walking and standing lameness scoring systems and behavior are promising tools for a producer to use on farm for lame sow identification. However, behavior assessments, mechanical nociceptive threshold testing and walking and standing lameness scoring were less correlative when evaluating the body system suspected to influence lameness. The Swine Lameness Diagnostic Manual was able to identify a presumptive lameness etiology for each case. However, a panel of practicing swine veterinarians unanimously agreed that the manual identified the correct and complete lameness etiology on only 4.3% of the cases after reviewing all data and diagnostic testing for each case.

▼ Introduction: In 2008, Ghana recorded the last case of poliomyelitis or polio and the
causative agent was the wild polio virus. The country has been certified free of polio and
it is at the verge of polio eradication. High levels of polio neutralizing antibodies
(immunity) must be maintained to prevent the importation of wild poliovirus. We
determined the seroprevalence of polio viruses (P1, P2, and P3) antibodies and the risk
factors for seronegativity in Greater Accra, Ashanti and Northern regions of Ghana in order
to identify any gaps for system improvement.
Methods: A cross-sectional, hospital-based seroprevalence study supplemented by a
school lameness survey was undertaken in the three study regions in 2016. Individuals,
who visited the three teaching hospitals of the regions and needed to give out blood samples
for laboratory investigation, were invited to partake in the survey. Micro-neutralization test
for poliovirus serotypes, 1, 2 and 3 antibodies was performed following WHO-standard
procedures. Antibody titers of ≥ 1:8 were considered positive. Bivariate and multivariate
analyses were conducted on subject characteristics to assess for potential factors for failure
to sero-convert. Statistical significance was set at P -values <0.05
In the school lameness survey, clinical and epidemiological data were obtained from
parents and their lamed children using a semi-structured questionnaire in the same three
regions. School lameness data was descriptively analysed by person, place and time by
employing frequency distributions, percentages, means, standard deviation and rates. Data
was analysed using STATA version 13.
Results: Neutralizing-antibodies against poliovirus types 1, 2 and 3 were detected in 86.0%
(264/307), 84% (258/307) and 75% (230/307) of samples respectively. Overall, 60.1%
(185/307) were seropositive and 2.9% (9/307) were seronegative for the three polio
serotypes. Seroprevalence of polio-neutralizing antibodies among males (P1=51.9%,
P2=51.6% and P3=52.6%) were higher than females. Seroprevalence rates of polio
neutralizing antibodies (P1, P2 and P3) were highest in the Northern Region (91.8%,
82.4%, and 77.4%). Polio neutralizing-antibodies (P1 and P2) decreased with age
[p<0.001]. Low seroprevalence of polio-neutralizing antibodies was significantly
associated with low school attendance of mothers [p=0.003 for PV1 and p<0.001 for PV2].
Prevalence of residual paralysis was 0.58/1,000 or 5.8/10,000 children aged 0-15years in
schools of the study regions.
Conclusion: This study revealed a moderate level of seroprevalence of neutralizing
antibodies to the three polio serotypes with some regional differences. Seropositivity was
generally low with increasing age and the mother’s education level was crucial to
seronegativity. The drastic reduction of paralytic poliomyelitis may be attributed to the
moderate level of polio-neutralizing antibodies.
To further strengthen the gains made in polio eradication, the Ghanaian government…

▼ A low level of sow retention in the herd is a cause for both economic as well as welfare concerns. The results of the study confirmed that a low lactation feed intake, incidence of lameness or health problems, as well as sow-level characteristics such as higher parity and fewer piglets born alive per litter may adversely affect sow longevity. Sows retained with periparturient health problems had reduced longevity and fewer live-born piglets, and fewer such sows had another farrowing. A prospective data analysis indicated that the overall performance of lame sows in terms of the number of pigs born alive during the period of the study was less, compared with that for non-lame sows. Retaining sows with less severe lameness may enable the producer to meet immediate production targets. The findings suggest that sow removal decisions should be judiciously evaluated after farrowing considering the potential long-term losses. Lameness in swine herds should be minimized and if treatment is not an option lame sows should be culled as soon as possible to reduce long-term losses.
The results also confirmed the high prevalence of claw lesions in breeding female pigs and their association with lameness, specifically, white line and side wall lesions. The results indicate the possibility of nutritional intervention in minimizing claw lesions. However, there are other factors associated with claw lesion development in pigs. The quality of the floor as well as different bio-mechanical factors operating in lesion development are important here. The space between slats, roughness of the surface, and edge design are critical in claw lesion development. Those factors have not been addressed in this study. Further studies are required to understand the mechanism of lesion development in relation to the housing and management systems in place. This information is vital in formulating the appropriate intervention strategy to minimize the incidence of lameness and to improve sow longevity and performance. The studies in this thesis included data from single herds and therefore the generalization of the results may be restricted owing to the wide variations in management, housing and in genetic lines of sows.

▼ Lameness, the most general clinical sign of musculoskeletal problems, is a serious welfare and health problem to sows and a cause of considerable economic loss to pig producers. Since 2013, group-housing of sows is mandatory in the European Union, mainly because of welfare concerns. Yet, the prevalence of lame sows tends to be higher in group-housing. A decline in the prevalence of sow
lameness by using proper preventive strategies is necessary to improve animal welfare, enhance farmer's working pleasure and diminish financial loss, all of which may contribute to a more sustainable pig production.
A critical review of the literature on sow
lameness (chapter 1) revealed that to enable optimal prevention of sow
lameness, more research is needed on three main areas. First,
lameness detection in sows so far has been based on subjective visual scoring systems characterized by a low sensitivity and high inter-observer variability. More objective, precise and sensitive detection methods based on kinematic and kinetic techniques have been successfully applied in other animal species but not yet in sows. Secondly, awareness of the economic implications is recognized as a potential powerful driver to motivate farmers to take action against
lameness. The financial loss related to
lameness is partly attributed to the (in)direct effect on reproduction. The indirect effect of
lameness on sows' reproductive performance has been studied extensively but inconsistency still exists on the direct impact. Finally, critical for the development of preventive strategies is to identify risk factors for
lameness. Although risk factors have been studied in stall-housed sows and finishing pigs, research on the risk factors for group-housed gestating sows is scarce.
The aim of this thesis (chapter 2) was to enhance prevention of
lameness in group-housed sows through improvement of
lameness detection, clarification of the reproductive implications and identification of risk factors.
To improve the detection of lame sows, a system, based on force and visual stance variables derived from balance analysis and image processing respectively, was developed: SowSIS (Sow Stance Information System) (chapter 3). The demountable and transportable device is practical for on-farm use and detects
lameness in sows while standing. Accuracy of the force stance variables was evaluated using reference masses ranging from 5kg to 175kg. SowSIS proved to be highly accurate (R² ≈ 1) for measuring weight, irrespective of the position of the mass relative to the load cell and the duration of measurements. To determine precision of the force and visual stance variables, five consecutive measurements with SowSIS were carried out for each of 20 pregnant sows that were scored healthy on visual
lameness assessment. A sufficient level of precision (within-animal CV ≤ 15%) was shown for both the force and visual stance variables, except for the number and duration of kicks (i.e. lifting leg off the ground) and weight shifts. A proof-of-concept study was performed on four…

▼ Cattle experience behavioral changes during incidences of discomfort such as respiratory disease, hock injuries, and
lameness. Visual evaluation of these conditions, particularly
lameness and respiratory disease can be subjective and may lead to untreated animals, which reduces the overall well-being of the animals. In order to improve detection of affected cattle, continuous or combined monitoring systems should be used. These technologies may improve detection compared to visual assessment by reducing human bias. Behavioral changes in particular may be detected through these means, with changes indicating potential health abnormalities in the individual cattle. One such behavior that changes during incidences of discomfort is lying laterality, or the preference of lying on one side over the other. Calves infected with the bacterium,
Mannheimia haemolytica, spent more time lying on their right side than their left side (7.8 ± 0.3 vs. 6.8 ± 0.3 h/d,
P = 0.01) and experienced a mild respiratory infection as indicated by greater rectal temperatures 12 hours post inoculation compared to control calves (41.3 ± 0.3 °C vs 39.2 ± 0.3 °C;
P < 0.01) and mean lung lesion scores (7.32 ± 0.39%). Lactating dairy cattle on Croatian dairy farms with unilateral hock injuries spent more time lying on their left side than their right compared to cows with bilateral injuries and uninjured cows (
P = 0.02). Changes in lying behavior combined with presence of lung lesions or hock injuries indicate increased discomfort and decreased welfare in calves and cows.

▼ Flunixin meglumine has been used as an antipyretic and
anti-inflammatory since the 1980s. In 2013, a novel formulation was
released in the European Union for topical administration and
transdermal absorption. Approval for transdermal flunixin in cattle
in the United States occurred in 2017, and included a label claim
for the control of pain associated with infectious pododermatitis
(foot rot). This new formulation allows for needle-less delivery of
flunixin with minimal restraint and training required.
In this
dissertation, the pharmacokinetics of transdermal flunixin in
Holstein calves at 2 months of age and adult lactating cows is
described. In these pharmacokinetic studies, plasma flunixin
concentrations were determined using high-pressure liquid
chromatography coupled with mass spectroscopy. Pharmacokinetic
modeling was completed using non-compartmental modeling methods
using a commercially available computer program.
Ex vivo
prostaglandin E₂ (PGE₂) production using a whole blood model served
as a biomarker for the anti-inflammatory effects of flunixin
meglumine and suppression of cyclo-oxygenase enzyme-2. The
concentrations of PGE₂ were determined using a commercially
available enzyme-linked immunosorbent linked assay (ELISA) kit.
The effects of age and pain on the pharmacokinetics of flunixin
were investigated. Both influenced the pharmacokinetics and
anti-inflammatory effects of flunixin. Cautery dehorning without
local anesthetic was used in the calf model to generate pain. The
pain associated with dehorning caused lower absorption of the
transdermal flunixin and a longer terminal half-life. This longer
half-life did result in lower PGE₂ concentrations at later time
points. The influence of age was determined in the same group of
Holstein calves at 2 months and 8 month of age. Age related effects
included lower clearance, a longer half-life, and longer
suppression of PGE₂ following intravenous injection. Following
transdermal administration, older animals had a prolonged
absorption leading to a longer half-life and apparent ‘flip-flop’
pharmacokinetics. Additionally, the suppression of PGE₂ was not
observed in older calves following transdermal flunixin
administration.
The analgesic properties of transdermal flunixin
were tested using three different pain models. Those pain models
include cautery dehorning, surgical castration, and induced
lameness. The reduction in plasma cortisol following transdermal
administration was the most consistent finding in each model for
pain. Infrared thermography (IRT) was used to assess either
activation of the autonomic nervous system or local inflammation.
Flunixin did not have any effects on substance P concentration in
all three pain models. Gait analysis using a floor based pressure
mat was used in the assessment of castration and
lameness pain.
Although there were no observed effects of flunixin in those
studies, the use of this technology for pain assessment is
promising.
Future studies of transdermal flunixin to determine
its utility as part of a multi-modal…

▼ The purpose of this experiment was to explore if correctively trimming sow claws would beneficially change the manner in which the sow walks. Welfare of the sows is a growing issue within the swine industry, and a major welfare problem is
lameness. In this experiment, sows were walked through a chute pre, one hour post and forty-eight hours post corrective trimming. The gait of each sow was captured using high-speed cameras to record video footage of each side of the sow simultaneously as
she walked through a 2.5 meter recording frame. The data were analyzed using Kinovea kinematics system and analyzed for swing, stance, break over, stride length, two- and three-limb support with comparisons being made between time points. The results
show marked difference between the sow’s gait pre and post corrective trimming for stride duration. The changes allow for a decreases in discomfort and degeneration of the skeletal system.

▼ A platform comprising four individual sections has been designed and built to determine a dairy cow’s weight, hooves’ position, the duration each hoof is on the section, and the stride length. The developed hardware and software is geared towards building a complete system to detect lameness in cattle, the ultimate aim of the project. Each section is an independent unit and consists of four ASB1000 shearbeam load cells, an AD7193 which is a 24-bit sigma-delta analogue-to-digital converter (ADC), and an ATmega328 microcontroller. The AD7193 ADC communicates with the microcontroller via the serial peripheral interface (SPI). Because each section contains its own microcontroller, an Arduino Mega 2560 has been used as the master microcontroller. This handles communication between the computer and all the sections. The master and sections communicate on a RS-485 half-duplex bus. The load cell values are transmitted from the master microcontroller to the computer via serial communication. The individual load cell value is then recorded and further processed where the data can be plotted, and the cow’s average weight, stride length, hooves’ position and duration can be calculated. The user also has the ability to render the data to a video file and to split cow data.
Laboratory testing was conducted to find the accuracy of the sections using a laser cut jig and a 20kg point load calibration weight. It was found that the X-position mean error is 1.0 ± 2.2mm, the Y-position mean error is 0.8± 1.8mm, and the total weight on the section has a maximum error of 0.4%. The mainframe to which the sections bolt to is 3000mm long and 540mm wide, while the individual sections measure 650mm long by 500mm wide. When the platform is assembled, the platform is 100mm high and has a walking surface width of 400mm. The platform sections are adjustable between the ranges of 700 ± 50mm to find the optimal stride length. The platform has been galvanized for protection against the elements. Experimental field testing was conducted at Massey Dairy Farm Number 1 where the signal signatures of 60 cows were recorded for further analysis. The recorded data was used as the basis for all the software tools that were developed; more field testing would be required to make the software more robust to different cow behaviours to see whether cow’s weight, hoof position, duration of each hoof and stride length can be successfully and accurately calculated.

▼ Lameness is one of the most important welfare issues in the dairy industry with all cows being at risk during their productive life. It decreases milk production, compromises fertility and increases the chance of being culled. To reduce the likelihood of lameness in cows, a thorough knowledge of the risk factors is essential. Risk factors have been found to differ between farming systems which highlighted the need for a project to identify risk factors of lameness in NSW pasture-based dairies. The thesis reviews the literature on risk factors pertaining to lameness in dairy cattle worldwide with focus on the main aspects of lameness regarding pasture-based dairy farming. First study investigates the prevalence and the potential risk factors for lameness in 62 pasture-based dairies in NSW with the aim to identify risk factors for lameness and to provide the industry with an indication as to the relative contribution of these risks so that dairy producers could allocate their resources to areas most likely to have the greatest impact when planning a prevention strategy. The data gathered through the interviews with farmers focuses on their perception of lameness in their herds. International experience suggests farmers’ perception of lameness are less than the true prevalence, which was proved to be the case in NSW, Australia. The reduced perception of lameness appears to be associated with delayed treatment and poor treatment outcome. Treatment outcomes may be further compromised by almost 30% of farmers or farm staff not having undergone training as to how to effectively trim and treat lame cows. The final study gathers data on wooden hoof blocks commonly used in treatment of lame cows. This study assesses the association between wood density, longevity, and wear characteristics of wooden hoof blocks. It was found that the hardness of the commercial blocks is insufficient to provide an appropriate duration of protection for healing claw lesions.

▼ This thesis was an investigation into better understanding the prevalence of hock and knee injuries, and abnormal locomotion on dairy cows in Ontario, Canada, the relationship between injuries and abnormal locomotion, and if injury resolution occurs based on housing environment. A 52-week observational study took place to describe the relationship between mild, moderate, and severe hock and knee injuries and
lameness in dairy cattle, and to determine if based on the type of hoof lesions present (non-infectious vs. infectious), and the treatment of regular hoof trimming, if cases of abnormal locomotion scores changed over time to become acceptable, and normal locomotion scores. Overall, the presence of moderate and severe hock and knee injuries were associated with abnormal locomotion scores. This association was further supported through the results on a larger dataset on the proAction Animal Care Assessment results for Ontario dairy farms. When following a regular hoof trimming schedule, it took around 50-days to see an improvement in locomotion score if a hoof lesion was present at the time of the trim. It is unknown if hock and knee injuries heal, based on descriptions of severity and complexity, and how long the healing process takes. A longitudinal observational study was developed to determine if hock and knee injuries heal or improve over time through facility transitions into housing environments that could promote healing, and how long this healing process takes. Fourteen commercial dairy farms were enrolled, 5 in Ontario and 9 in Nova Scotia, based on housing type and cow housing transitions made on the farm. A total of 598 cows were assessed for the presence of hock injuries using the Canadian proAction Animal Care Assessment scoring system. Overall, 77% of cows that transitioned with moderate hock injuries healed, 36% of cows with a severe hock injury, and 100% of cows with moderate knee injuries healed. Environments that promoted the most healing were deep bedded sand and pasture. The results of this thesis can help provide realistic timelines and expectations for dairy producers to implement corrective action plans to decrease the prevalence of injuries and
lameness on their farms.

▼ Reason for performing the study: An inertial sensor-based system (
Lameness Locator[copyright] [LL]) can help veterinarians detect mild
lameness. It would be beneficial if this tool could also be used to distinguish lamenesses produced by lesions in different structures. Hypotheses: Coffin arthritis predominantly causes impact
lameness while shoulder arthritis predominantly causes pushoff
lameness. Objective: To investigate if shoulder arthritis causes pushoff
lameness and coffin arthritis causes impact
lameness and if these lamenesses can be differentiated by comparing the phase angle of the resultant ray calculated by the LL. Methods: Using a crossover design, coffin and shoulder arthritis were alternately induced in 12 horses with intra-articular injection of IL-1[beta]. Immediately before injection and every 6-12 h thereafter, the horses were evaluated with the LL. This evaluation was performed while the horses were trotted in hand in a straight line on a hard surface for about 120m. The phase angle (= arctangent [MINDIFF mean / MAXDIFF mean]) of each type of
lameness (coffin or shoulder arthritis) were compared with the Wilcoxon signed-rank test using data from the last time point before
lameness was no longer detectable. Results: No difference could be detected (p=0.625) between the phase angle when coffin (median, 81[degrees]; range, 58-123[degrees]) and shoulder arthritis (median, 86[degrees]; range, 59-104[degrees]) were compared. Conclusion: Coffin arthritis and shoulder arthritis did not consistently cause impact
lameness and pushoff
lameness, respectively.

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Recently developed wireless inertial sensor systems provide a means to objectively detect
lameness as a horse is trotted over natural footing. The purpose of this study was to compare one such inertial sensor based system to subjective evaluation performed by experienced equine practitioners of horses with
lameness induced by sole pressure. Fifteen horses were fitted with special shoes, which allowed for
lameness induction via sole pressure. Before each trial the horses were fitted with three wireless inertial sensors. Horses were subjected to multiple trials: 1) immediately before inserting the screw, 2) immediately after inserting the screw to just touch the sole, and 3) after gradually tightening the screw in half turn increments. The number of half turns of the screw required for consistent identification of
lameness in the correct limb by the inertial sensors and through the consensus of three equine veterinarians was compared using the Wilcoxon's sum rank test. The inertial sensor system selected the correct limb sooner (i.e., after few screw turns) than the veterinarians (P<0.0001). The 3 veterinarians selected the correct limb before the inertial sensors in five trials (8.3%). The opposite occurred in 43 trials (71.6%). The 3 veterinarians and the computer simultaneously selected the correct limb in 12 trials (20%). The inertial sensor based system was more sensitive relative to the consensus of 3 equine veterinarians to identify the affected limb in horses subjected to sole pressure induced
lameness.

▼ Disorders of the locomotor apparatus are very common in sports horses. Pain and dysfunction associated with these conditions have a negative impact on horse welfare. The main component in lameness evaluation is detection of vertical movement asymmetries but the inter-rater agreement among veterinarians is low. Therefore, modern methods of detection and quantification of movement asymmetry have been developed.
The aim of this thesis was to help improve equine welfare by providing a better scientific basis for interpretation of movement asymmetries. This could support riders and veterinarians in detecting lameness at an early stage and improve orthopaedic diagnostics.
To investigate a possible association between movement asymmetry and presence of painful orthopaedic conditions, NSAID (meloxicam) treatment was performed in asymmetrically moving, but presumed sound horses. Interestingly, this did not decrease the magnitude of asymmetry. Other reasons for asymmetric movement and the clinical efficacy of treatment with meloxicam in relation to a potentially present pathology therefore need to be addressed.
The influence of the rider’s seating style on vertical movement symmetry in trot was evaluated in 26 horses. ‘Rising trot’ induced systematic changes, the most prominent being a decreased pelvic rise, mimicking push-off lameness in the hindlimb of the diagonal on which the rider was sitting in ‘rising trot’.
The potential of the relationship between the direction of head and withers movement asymmetry parameters to assist in locating the primary lame limb was investigated in horses with induced lameness. The findings were then verified in horses with naturally occurring lameness. The results showed that head and withers movement asymmetry parameters indicate the same forelimb in horses with forelimb lameness, but indicate opposite forelimbs in horses with hindlimb lameness and compensatory head movement asymmetry.
The results presented in this thesis extend existing knowledge about the origin and significance of movement asymmetries in riding horses and compensatory mechanisms in lame horses

▼ The objective of this study was to estimate genetic parameters and breed and crossbreeding effects on incidence of recorded clinical lameness (RCL) in New Zealand dairy cattle. Herd records from 76,357 cows distributed in 155 herds dedicated to the Livestock Improvement Corporation (LIC) sire-proving scheme during the 2005 to 2009 milking seasons were used to estimate the phenotypic, additive genetic, permanent environmental and residual variances of RCL in Holstein-Friesian (F), Jersey (J) and crossbred (FxJ) dairy cattle. RCL incident was coded “1” for cows that had at least one event of RCL at any day during lactation and a “0” code was used for cows without a RCL incidence. Genetic parameters and crossbreeding effects on RCL were estimated with a repeatability animal model, across breeds using restricted maximum likelihood methodology. The predicted mean incidence of RCL per herd was 7.74% with a range of 2% to 34%. Heritability estimate for the incidence of RCL for all lactations (1st to 10th lactation) was 0.016 ± 0.003 (± SE) and the repeatability was 0.071 ± 0.005. The heritability estimate of RCL using only first lactation records was 0.05 ± 0.01 (± SE). Jersey cows had a lower mean (± SE) incidence of RCL than F cattle (J: 6.67 ± 1.50%; JxF: 6.89 ± 1.50%; F: 8.83 ± 1.50%). The effect of first cross (F1) FxJ crossbred was -1.2 ± 0.3% (± SE), representing a mean 16% reduction in RCL compared to an average of the parental pure breed J and F cattle. There was considerable variation (-5 to 8%) between sire estimated breeding values for RCL, suggesting that sire selection across breed and within breed could result in increased genetic resistance to RCL in New Zealand dairy cattle. A significant (P<0.05) reduction in mean (± SD) milk solid yield per day was found in cows with RCL (1.40± 0.0012 kg) compared to cows without RCL (1.43± 0.0045 kg). Cattle in first lactation had a significantly higher incidence of RCL than cows in subsequent lactations (7.6 ± 0.1%, 4.6 ± 0.1%, 5.2 ± 0.1%, 6.3 ± 0.1% and 7.0 ± 0.2% (± SE) for first, second, third, fourth and fifth lactations, respectively). These results suggest that selection for resistance to lameness will result in a low rate of genetic gain but using Jersey sires can be an alternative to increase genetic resistance to lameness in New Zealand dairy cattle.

▼ Nowadays, horses have to train and perform in high-level sportive and leisure activities. Injuries of the locomotor system with a decreased functionality or pain of the back are often seen in equine hospitals. In general, the relationship between limb and vertebral column function in mammals is complex and has been of scientific interest for long time. The age-old bow-and-string concept of the mammalian back, which implies that several body parts influence back motion (Barthez 1798; Slijper 1946), needed a detailed update. In horses, the origin and pathogenesis of back problems are difficult to predict with clinical examination alone, and thus deserves an objective evaluation and investigation. Modern gait analysis technology allows for an objective, more accurate and detailed analysis of body kinematics to study how limbs interact with vertebral column movement (Chapter-1). In Chapter-2 it was shown that changes in the head-and-neck position influence back kinematics. Lowering the head-and-neck flexes the vertebral column, while it increases range of motion (ROM); by lifting the head-and-neck the column extends and ROM becomes reduced. It was concluded that the low position of the head-and-neck increase vertebral movement. On the other hand, an extremely high head-and-neck position provokes reduced movement and an extended posture of the back. Back pain and lameness do coexist and commonly the primary cause of the problem is clinically found in the limbs. In Chapter-3 and-4 the relation between slight lameness and vertebral motion was investigated. It was shown that even subtle forelimb and hindlimb lameness provoke systematic changes in pelvic and thoracolumbar kinematics. Induced forelimb lameness provoked increased ROM and changed the pattern of thoracolumbar motion in the sagittal and horizontal planes. Hindlimb lameness resulted in hyperextension and increased ROM of the back, but also in a decreased ROM of the lumbosacral segment. All changes presumably are done in an attempt to unload the affected limb. In Chapters-5 and-6 it was shown that induced unilateral back pain affects back and limb kinematics. Vertebral ROM increased, the position of the back was more extended and showed increased lateral motion. However, the effect of back pain on limbs was rather minimal consisting in decreased flexion of some of the joints of all four limbs during swing phase. Thus, it can be assumed that primary back pain is unlikely to produce important changes in the limbs. In Chapter-7 the effect of chiropractic manipulations on horses with back pain was studied. Understanding the effect of back and limb pain experimentally, it could be hypothesized that treating back pain would induce biomechanical changes in the vertebral column. The main effect of the chiropractic manipulations was a less extended thoracic back, enhanced vertebral ROM, a reduced inclination of the pelvis and improvement of the symmetry of its motion. It can be concluded that there is a tight functional relationship between vertebral column and limbs. When…

▼ Lameness in dairy cattle remains an important issue because of economic losses and the negative effects on animal welfare. In the present study, the aim was to investigate the effects of housing parameters on claw
lameness in dairy cattle. The Cow Comfort Scoring system of van Eerdenburg was used assessing housing parameters and cow comfort on 14 Dutch commercial dairy farms. The 14 farms were visited once between March and July 2011. A total of 1626 lactating dairy cows were individually scored with the locomotion score by Sprecher. The exorotation of the hindleg and claw measurements from the hindleg claw were also taken from those diary cows. It was expected that incorrect housing, especially cubicles and flooring, and insufficient cow comfort would lead to
lameness. Additionally, the hypothesis was that claw measurements and exorotation of the hindleg had a good predictive value for
lameness.
The average
lameness prevalence in this study was 39% (range=22-56%), while 14% (range=3-32%) of dairy cows had locomotion score 3 or higher according to the locomotion scoring system of Sprecher. The Cow Comfort Score (average 262 out of 500 range=169-334) had a significant predictive value for
lameness when considering locomotion score 3 and higher (R2 = 0,282/P = 0,051). Furthermore, this study supports the hypothesis that exorotation of the hindleg and the length of the claw affect
lameness.
This study did not find a significant relation between
lameness and cubicle conditions or cubicle dimensions. However, ‘Cows standing in idle,’ which is a sign of decreased lying comfort, did show a significant relation with
lameness. Flooring was not significant, but the ‘Width of the alleys’ was. Possible explanation is that this study contained only a small amount of observed farms and only 3/14 farms had sufficiently good housing and cow comfort, which also leads to less variation and as a result it has proven to be difficult to statistically prove predictive parameters for
lameness.

▼ In Chapter 1 the Polar system is validated.
Materials and methods: Polar RS800 CX-model (Polar® Electro Oy, Kempele, Finland), telemetric ECG system (3-lead Spacelab Holter system, Del Mar Reynolds Medical, Hertford, UK). Nine horses measured during one week. Three Polar error correction settings compared to ECG-results.
Results: Results obtained by the RMSSD showed a higher R2 compared to R2 of the SD scatter diagrams. Significant correlation was confirmed in RMSSD models of the Polar 1 and the 2 setting during rest and walk.
During walk of the Polar 1 and the Polar 2 setting an R2 of respectively 0.695 and 0.717 in contrast to the resting values of the Polar 1 and the Polar 2 setting with an R2 of respectively 0.600 and 0.458, was calculated.
SD, on the other hand, only showed significant correlation with ECG-results after extraction of two horses with second-degree AV-block in the Polar 2 and the Polar 3 setting. Nevertheless, the scatter plots of both the Polar 2 and the Polar 3 setting still displayed a low R2 after extraction of these two horses.
Conclusions: Polar RS800 CX-model with a low filter correction (Polar 2) in the walking-gait was chosen to be used instead of an ECG-telemetric system for gathering HRV-data in the form of RMSSD for practical reasons.
In Chapter 2, the effect of exercise on HRV is investigated.
Materials and Methods: nine horses measured ten weeks by the Polar system (Chapter 1). Three groups: elite, midclass, non-elite. Four activity-levels (rest, walker training, dressage training, trail conditioning).
Results: Elite horses had an RMSSD which was significantly higher compared to the RMSSD of midclass and non-elite horses after a resting day. The midclass horses also had a significantly lower RMSSD compared to the RMSSD of non-elite horses after a day of rest.
After walker training the elite class had an RMSSD significantly higher compared to the RMSSD of midclass horses.
There was a decrease in RMSSD measured in all the horses grouped together (elite and midclass) from measurements after a walker training day compared to the RMSSD the day after trail conditioning.
When comparing the RMSSD after walker training with the RMSSD after a day of rest, all classes included, the RMSSD after a day of walker training was significantly higher than the RMSSD after a day of rest.
Conclusions: Various levels of activity had a significant effect on the HRV and the groups of trained horses had different HRV alterations secondary to various levels of activity.
In Chapter 3, the effect of
lameness on HRV is investigated.
Materials and methods: Nine horses measured (2 lame, 7 sound), during ten weeks (Chapter 2).
Results: The elite-horse had a higher mean RMSSD than the permanently lame non-elite horse.
Conclusion: No significant differences in HRV in lame versus sound horses were found in this study design. The two lame horses showed a significant difference between their mean RMSSD values, where the elite horse had a higher RMSSD compared to the permanently lame horse in the non-elite group.

▼ O presente estudo teve como objetivo avaliar, clínica e radiograficamente a utilização de cunha de osso alógeno córtico-esponjoso liofilizada e esterilizada em raio gama, obtida de banco de ossos, implantada como espaçador na TTA modificada em 16 joelhos de 15 cães com diagnóstico clínico de doença do ligamento cruzado cranial. Os pacientes foram submetidos a radiografias e avaliação da locomoção previamente ao procedimento cirúrgico. No pós-operatório, as avaliações foram realizadas imediatamente após a cirurgia e aos 30, 60, 90 e 120 dias. A ferida cirúrgica foi avaliada quanto a sinais de infecção e rejeição do implante ósseo. Locomoção foi graduada em escores 0-5, sendo 0: paciente clinicamente saudável e 5: impotência funcional do membro. As interfaces corpo da tíbiaimplanteósseo-crista tibial foram avaliadas radiograficamente em escores de 0-3 cada interface, sendo 0: nenhum contato entre implante e osso adjacente e 3 ponte óssea em toda extensão da interface. Os pacientes apresentaram boa recuperação clínica e radiográfica. A utilização dos espaçadores ósseos para TTAm oriundos de banco de ossos apresentou praticidade e comodidade em termos de armazenamento e transporte dos ossos. O espaçador ósseo liofilizado permitiu execução rápida e satisfatória da TTAm, apresentando resistência à perfuração e fixação com parafusos em 87,5 % dos casos (14, n=16) e tempo cirúrgico médio de 45,9 minutos. Não se observou reações imunogênicas com consequências clínicas em 93,7% dos casos. Um paciente (n=16) apresentou infecção do foco cirúrgico, com remissão dos sinais após terapia antimicrobiana. Foi possível verificar recuperação funcional do membro em todos os pacientes, sendo observado aos 120 dias, maior número de pacientes clinicamente saudáveis em comparação aqueles com claudicação (p≤0,05). Em todos os pacientes, foi possível verificar incorporação do implante ósseo à tíbia. A união óssea ocorreu de forma progressiva, sendo os estágios de união óssea observados nas radiografias aos 60, 90 e 120 dias significativamente maiores (p<0,05) que aqueles observados aos 30 dias e pós imediato. Com base nos dados desta pesquisa foi possível concluir que o osso liofilizado apresenta baixa imunogenicidade, propriedades osteocondutoras e osteoindutoras quando utilizado como espaçador na TTAm. Este espaçador mantem o avanço da tuberosidade tibial adequadamente, permitindo recuperação clínica dos pacientes enquanto o gap na tíbia é preenchido com osso neoformado.
This study proposed to use wedge of lyophilized corticocancellous bone and sterilized by gamma ray, obtained from bone bank, as a spacer device in TTA modified in 16 knees of 15 dogs with cranial cruciate ligament disease. Animals were submitted to radiographic and gait assessments preoperatively,early postoperatively and following 30, 60, 90 and 120 days. The surgical wound was evaluated for signs of infection and rejection of the bone implant. Locomotion was graded 0-5, with 0: clinically healthy patient and 5: limb functional impotence.

▼ The measurement of pain has had a growing importance in animals for both privately owned animals and those animals involved in clinical research.
Lameness is considered to be 1 aspect of the pain experience. The ability of a veterinarian to assess
lameness during a routine orthopedic examination can be difficult given the short amount of time in which the clinician can observe the animal, and the fact that the animal is in a stressful environment. Thus, the input of the owner concerning the animal's well-being over an extended time period may be extremely useful to the clinician in assessing the degree of
lameness of the animal. It was the purpose of this study to establish an instrument that was both repeatable and valid in assessing the degree of
lameness. The instrument used was a questionnaire containing 39 questions in a visual analog scale format. A force platform was used as the gold-standard for detecting mechanical
lameness. Peak vertical, cranial-caudal, and their associated impulses were forces used to determine
lameness, along with maximum slope in some cases. A test-retest measure of repeatability was conducted on a subset of 19 dogs that were confirmed to have less than a 10% change in vertical peak force. Nineteen of the 39 questions were found to be repeatable based on a Spearman rank correlation. These 19 questions were then used as predictor variables in several multiple regression models which predicted force plate measurements. The result was 3 different models each containing 7 independent variables that were thought to be valid representations of the forces measured (vertical peak, vertical impulse, and propulsion peak forces). Each reduced model was found to fit the data as well as the full model containing all 19 of the repeatable questions. The composite of 11 questions from the 3 different models was used to calculate a total score. This total score was found to be significantly correlated with force plate measurements. These 11 questions should be useful to a clinician in detecting the degree of
lameness in the dog.

▼ The objective of this study was to characterize kinetic and kinematic variables in dogs with forelimb
lameness and determine
lameness cutoff values of gait variables using ROC analysis with observational gait analysis (OGA) as reference. Twenty client-owned dogs with unilateral
lameness were included. Dogs underwent orthopedic exam, including OGA, and instrumented gait analysis (IGA; kinetic and kinematic analysis). Kinetic variables with the highest accuracy were PVF and %WD with an area under the curve (AUC) of 0.73 and 0.92, respectively. Optimal cutoff value for PVF and %WD were ≤ 10.6 (sensitivity 70% and specificity 75%) and ≤ 29.7 (sensitivity 90% and specificity 85%), respectively. Results of the ROC analysis indicate that KVs were most useful in determining
lameness.

▼ Dissertação de Mestrado Integrado em Medicina Veterinária
A osteoartrite é a principal causa de claudicação na espécie equina, sendo um factor limitante sobretudo para cavalos de desporto. Existem inúmeras formas de tratamento da osteoartrite (OA), sendo a corticoterapia a mais utilizada. O ozono é uma molécula com inúmeras acções terapêuticas de elevado interesse na medicina, sobretudo devido à escassa ocorrência de efeitos secundários. A ozonoterapia é um tratamento que tem sido um sucesso relativamente recente na Medicina Humana, tendo já sido também instaurada na Medicina Veterinária com bons resultados. Este trabalho engloba um estudo experimental, em que foram feitas administrações de Ozono intra-articular em boletos de cavalos com osteoartrite na mesma articulação. Os cavalos que foram seleccionados para o estudo tinham vários requisitos a cumprir, entre eles, o mais importante é que tinham de ter uma claudicação com origem num boleto e devido a osteoartrite. Tal requisito deveu-se ao facto de o objectivo principal do
estudo se basear na avaliação da melhoria da claudicação, após o tratamento com ozono. Após terminado o estudo, os resultados foram satisfatórios ao revelarem melhorias em todos os cavalos intervenientes no estudo, não só a nível da dor que estes exibiam e se revelava na claudicação mas também a nível da inflamação articular. Podemos assim concluir que a Ozonoterapia intra-articular em equinos pode vir a ser uma alternativa cada vez mais a ter em conta.
ABSTRACT - INTRA-ARTICULAR OZONE THERAPY IN FETLOCKS OF HORSES WITH OSTEOARTHRITIS: WHICH ARE ITS IMPROVING EFFECTS IN THE DISEASE? - Osteoarthritis is the main cause for lameness in the equine species, as well as a restrictive factor mainly for sport horses. There are numerous treatment methods when it comes to osteoarthritis (OA), but corticotherapy is the most commonly used. The ozone is a molecule with several and highly relevant therapeutic uses in medicine, above all because the side effects are rare. Ozone therapy has been, therefore, a relatively recent success in human medicine, and it has also already been introduced in veterinary medicine with good results. This thesis includes an experimental study in which several administrations of intra-articular ozone in fetlocks of horses with osteoarthritis were made. The horses selected for this study had to comply to certain requisites, among which the most important was the fact that they had to show a lameness
caused by osteoarthritis and originated in one of the fetlocks. This requisite was important because the main goal of the study was based on assessing the improvement in lameness after the treatment with ozone. After the end of the study, the results were satisfactory and revealed improvement in all the horses treated, not only in terms of the pain level each one of them presented and was evident in the lameness, but also when it came to articular inflammation. We can thus conclude that intra-articular ozone therapy in equines can become a more and more valid alternative.

▼ The objective of this dissertation was to determine the impact of four new methyl methacrylate (MMA) resin aggregate flooring types (1-4) compared to rubber and concrete controls, on dairy cow ease of movement when walking on straight and right angled corridors. Cattle ease of movement was measured using kinematics, accelerometers and visual observation of gait and associated behaviours. Stride length, swing time, stance time and hoof height for each passage were obtained from kinematic evaluation. Acceleration and asymmetry of variance were measured for each passage with accelerometers. Locomotion score and behaviours associated with
lameness, such as arch back, head bob, tracking up, step asymmetry and reluctance to bear weight were visually observed. Stride length, swing time, stance time and the number of steps taken were the only variables affected by flooring type. Stride length was longer (better) on rubber when compared to concrete and MMA 1 and 2. On MMA 3 and 4, it did not differ from either rubber or concrete. Swing time was shorter (worse) on MMA 1 than on rubber, but did not differ from any other flooring. Stance time was longer (worse) on MMA 2 when compared to rubber and MMA 3, but it did not differ from any other treatment. The number of steps was higher on MMA 4 compared to rubber, but did not differ from any other treatment. Of all the MMA floors tested, MMA 3 was the only one that was consistently as good as rubber, the positive control, at promoting ease of movement.
