▼ There is little information regarding the molecular events that govern the beneficial adaptations of equine skeletal muscle in response to acute exercise and training. This work addressed this subject in two manners. First, based on the comparative mammalian literature, signaling and gene expression markers related to S-ER stress and proteostasis were analyzed in equine gluteus medius biopsies before and after acute high-intensity exercise in the untrained and trained states. Protein expression analysis revealed that S-ER stress signaling was apparent, however, many downstream mRNA expression markers were not significantly impacted by acute high-intensity fatiguing exercise in the untrained state. Twelve wks of training, however, altered S-ER stress signaling as well as the expression of genes related to apoptosis and protein degradation. Additionally, mRNA expression markers of protein degradation were not impacted by acute fatiguing exercise in the untrained state; however, training status did alter the exercise-induced gene expression of the E3-ubiquitin ligase, Fbxo32. Lastly, training also compressed the mRNA expression variability in most S-ER stress-related genes, both basally and post-exercise. Second, based on the gene expression data, a non-targeted metabolomics approach was employed in order to assess the phenotypic variability in skeletal muscle at the level of metabolites. Metabolic differences in the early (3 h) and late (24 h) recovery periods were also assessed. In agreement with the gene expression findings, PCA and hierarchical clustering analysis of muscle biopsies revealed that training dominated the skeletal muscle phenotype and produced a homogeneous basal and exercise-induced metabolic signature among the horses. Early metabolic alterations largely centered on the branched-chain amino acids, microbial-derived xenobiotics, and a variety of lipid and nucleotide-derived compounds, especially in the trained state. Further, training increased the abundances of almost every identified long-chain free-fatty acid and complex lipid species in the pre-exercise condition. These elevations declined over 24 h following acute fatiguing exercise and were associated with increased gene expression related to lipid uptake and utilization. Finally, in an extension of the first two studies, the final objective of this work was to identify the impacts of prolonged training and detraining on body composition and aerobic and athletic capacities, as very little information exists regarding these training periods in the horse. Twelve wks of training caused a robust increase in VO2max and athletic capacity, with geldings outperforming mares. There was, however, no concomitant improvement in body composition during this period. An additional 60 wks of training was accompanied by a worsening of body composition in both sexes whereas aerobic capacity and athletic capabilities were maintained. Interestingly, 20 wks of detraining resulted in a maintenance of VO2max and performance despite a statistically significant… Advisors/Committee Members: Anthony, Tracy G (chair), McKeever, Kenneth H (co-chair), Watford, Malcolm (internal member), Shapses, Sue (internal member), Arent, Shawn (internal member), Malinowski, Karyn (outside member), School of Graduate Studies.

▼ The social intelligence hypothesis states that the main selection pressures driving increases in brain-to-body ratio are social rather than ecological. The domestic horse is an ideal animal to study within this framework because horses possess rich social lives but inhabit simple ecological environments. Here I assess the abilities of horses within two broad areas of social cognition; the classification of, and the use of information obtained from, social partners. In Section One I demonstrate that horses are capable of cross-modal individual recognition of conspecifics, an ability not previously demonstrated conclusively outside of humans. This ability extends to identifying familiar human companions suggesting that recognition systems are highly plastic in the individuals they can encode. These results also provide the first insights into the brain mechanisms involved in this process by revealing a clear left hemisphere bias in discriminatory ability. In Section Two I investigate the extent to which horses are capable of reading human attentional and communicative cues. It has been suggested that this skill was selected for through the process of domestication, however there have been no systematic studies of domestic animals other than the domestic dog. I found that horses were indeed highly skilled at determining if people were paying attention to them. In contrast they tended to only use basic stimulus enhancement cues to choose a rewarded bucket. A further study of young horses indicated that the ability to detect human attention requires significant experience to develop fully whereas the ability to use stimulus enhancement cues in an object choice task appears to require far less (if any) experience to develop. Overall my thesis extends our knowledge of comparative social cognition and in particular our knowledge of social cognition in horses. Taken together, these results clearly demonstrate that horses do indeed possess some complex socio-cognitive skills.

▼ Selection after domestication has primarily focused on performance, conformation and desirable behaviors in the horse, resulting in breeds that are divergent across these traits. An example are the "gaited" breeds, horses with the ability to perform either a lateral or diagonal fourbeat gait without a moment of suspension at intermediate speeds, yet varying in overall size and temperament. To investigate the contribution of genetics to these divergent traits, we collected DNA samples, 35 body measurements, gait information, horse discipline, and a behavior survey from 801 gaited horses. Utilizing previously genotyped horses, an across-breed genome-wide association study (GWA) identified three novel candidate regions associated with gait type on ECA1, ECA11, and EC4. A GWA in a single gaited breed, the Tennessee Walking Horse (TWH) identified two additional candidate regions on ECA19 and ECA11. Polymorphisms from whole-genome sequences have identified several SNPs within these candidate regions. We conducted principle component analysis (PCA) on 33 of the body measures for a subset of TWH. A GWA of the first PC, which describes overall size, identified the LCORL locus, which has previously been implicated with size in horses, cattle, and humans. No causal variant has been discovered yet due to extensive linkage disequilibrium (LD) in the region, but LD in the TWH is much lower, improving the resolution capabilities for fine-mapping and variant discovery. To investigate the contribution of genetics to temperament, we utilized factor analysis (FA) on the questionnaire to identify four temperament factors in TWH: neophobia, trainability, hostility, and independence. These four factors account for 64% of the total trait variance. We ran three separate GWAs using the F1-'neophobia', F2-'trainability', and F3-'hostility' scores as the phenotype and identified candidate markers in genes involved with neurodegeneration, steroidogenesis, brain development, and neuronal cell signaling pathways. The results from this work will hopefully lead to future studies to identify the causal variants of locomotion, size, and behavior traits. This will allow for the development of genetic tests to aid horse owners in their breeding and management decisions and help improve horse welfare as horses are selected for appropriate disciplines.

▼ Equine athletes participate in a wide range of equestrian disciplines. Performance analysis in sport is the collection and subsequent analysis of data, or key information sets, related to facets of training and / or competition, to accelerate and improve athletic performance. Equine performance analysis research aims to optimise the potential competition success of the horse whilst concurrently promoting health and welfare and increasing career longevity. Despite the benefits associated with performance analysis, its application is limited in equine sport. Surface electromyography (sEMG) is a non-invasive technique which illustrates recruitment patterns of superficial skeletal muscle and can provide quantitative data on the activity within muscle during dynamic motion. sEMG has the potential to contribute to equine performance analysis particularly via assessment of muscle recruitment, activity and adaptation within training regimens and during competition. The critical commentary demonstrates the potential of surface electromyography (sEMG) as an effective performance analysis tool that could be used to assess the physiological response of muscle during field-based exercise in the horse and provides examples of how sEMG data obtained could guide improvements in the efficacy of training regimens for the equine athlete. Critical reflection on four peer-reviewed evidence sources was conducted to establish their contribution to equine performance research and to facilitate debate of future research directions for equine sEMG. The research demonstrates the validity of telemetric sEMG as an emerging technology that could be used to analyse muscle performance in the equine athlete for defined events, for example jumping a fence, and to assess performance over time, for example monitoring muscle activity during interval training. Opportunities also exist to determine the efficacy of muscle-related clinical and therapeutic interventions such as prophylactic dentistry or physiotherapy. The preliminary research presented suggests the use of equine sEMG as a performance analysis tool has most value to assess and compare muscle performance during exercise within individual horses. However further research is required to substantiate this. Future studies integrating larger sample sizes, horses selected from specific equestrian disciplines and breeds, and further exploration of the impact of coat length and sEMG sensor placement on data obtained would be worthwhile to standardise and validate the protocols employed here. Equine performance is a complex area; future work needs to focus on the individual characteristics that contribute to desired performance goals, but should also evaluate performance as a holistic entity. It is essential for progression in the performance field that research undertaken is shared with the equine industry to enable practical implementation. The use of sEMG in the equine athlete has the potential to increase understanding of how muscle responds to exercise and could help create an evidence-base to…

▼ Living in complex societies is thought to promote the development of sophisticated social, cognitive, and communicative skills. Investigating the extent of these skills across taxa is critical to understanding the evolution of the advanced abilities found in some species, including humans. Facial expressions are rich sources of social information for humans and some primates; however whether this is true for other animals is largely unknown. Horses are an ideal study species for these questions: they form valuable social relationships and display some advanced socio-cognitive skills, but are phylogenetically distant from primates and so might be expected to communicate quite differently. Here I present a method for quantifying and coding horse facial movements (EquiFACS), which reveals that horses have an extensive capacity for producing facial expressions. I then utilise EquiFACS to demonstrate that horses produce facial actions that mirror the emotional content of auditory stimuli, providing evidence for a perception-action representation of emotional information. Through my experiments on the perception of facial expressions in horses I show that these expressions display meaningful information to conspecifics, which influences their behaviour in functionally relevant ways. I also shed light on the physiological processes involved in the perception of emotional conspecific facial expressions, showing that viewing negatively valenced conspecific emotional expressions raises resting heart rate. This is indicative of emotional contagion, which may be a mechanism through which information is obtained and social interactions are regulated. Collectively, my research demonstrates the ability to produce and use complex facial expressions as a source of social information is not limited to primates, but is present in at least two phylogenetically distant groups. This suggests these skills may either be an evolutionarily conserved trait or have evolved under common selective pressures. As well as their scientific significance, these findings have implications for horse management and welfare.

▼ Staphylococcus aureus is a coagulase-positive, Gram-positive, coccal bacterium. It is one of the leading causes of both skin and invasive infections. It plays an important role in diagnostics and treatment due to its ability to develop resistance to antimicrobial drugs. Methicillin-resistant Staphylococcus aureus or MRSA is an important nosocomial pathogen in both humans and animals due to its resistance to all ?-lactam antimicrobial agents. Colonization of MRSA in horses poses a great concern. This is considered an important risk factor for development of staphylococcal related diseases in horses admitted to veterinary hospitals. Colonized horses can also be a source of zoonotic MRSA infections. Methicillin-resistant Staphylococcus aureus detection based on a PCR reaction is commonly used and various types of PCR-based assays were developed to assist in early detection of MRSA. The main aim of the study was to compare the currently used conventional microbiological techniques with a published multiplex PCR assay targeting the mecA, spa and pvl genes for the rapid and accurate identification of MRSA in horses admitted to the Onderstepoort Veterinary Teaching Hospital, University of Pretoria. A total of 50 isolates, which consists of isolates from horses and their immediate environment, were included in the study of which 94% (n=47) were shown to be infected with methicillin resistant Staphylococcus aureus using conventional microbiological techniques. The remaining three gave inconsistent results. Their isolates were obtained, DNA was extracted and subjected to the multiplex PCR assay. The PCR results indicated that both the mecA and spa genes were present in 72% (n=36) of these isolates, indicative of MRSA strains. In 20% (n=10) of the isolates, only the spa gene could be detected; suggesting that these cannot be classified as being methicillin resistant. The pvl gene could not be detected in any of the isolates tested. A total of four isolates (8%) yielded results that were inconsistent with being MRSA using molecular identification. Overall there was a good correlation between genotypic analysis by PCR and phenotypic determination using S. aureus species identification and susceptibility testing methods. The multiplex PCR assay had a detection limit of 2.18 x 108 colony-forming units (cfu)/ml. This detection limit is higher compared to other published molecular identification techniques used for Staphylococcus aureus but sensitive enough for the accurate detection of MRSA in overnight cultured isolates. Results suggest that the current PCR assay could be used as a supplementary diagnostic method in the routine diagnosis for rapid, sensitive, and specific detection of S. aureus and its associated antibiotic resistance genes in equine samples.

▼ Equine influenza is a highly contagious and widespread viral respiratory disease of horses and other equid species, characterised by fever and a harsh dry cough. Prior to August 2007, Australia was one of only three countries to have remained free of equine influenza. An incursion of equine influenza virus H3N8 in that month resulted in a four-month outbreak during which approximately 69,000 horses were infected on an estimated 9599 premises across two States. Most of the geographic spread occurred within the first 10 days and was associated with the movement of infected horses prior to the implementation of movement controls. The outbreak was contained through a series of interventions that ultimately led to the eradication of equine influenza from Australia. During and immediately after the outbreak, intensive epidemiological investigations, laboratory and retrospective analytical studies were conducted culminating in a series of detailed reports and publications, and the collation of a highly detailed outbreak dataset. Further research into the factors that contributed to the spread of the outbreak and the effectiveness of measures implemented to control and contain it was considered important. The aim of this thesis was therefore to investigate the factors that contributed to the spread of the 2007 equine influenza outbreak in Australia and to develop statistical methods and tools useful for informing the surveillance and control of future emergency animal disease events. A case-control study was conducted to investigate premises-level risk factors, specifically whether compliance with advised biosecurity measures prevented the spread of equine influenza onto horse premises. Horse owners and managers on 200 properties across highly affected areas of New South Wales were interviewed. The proximity of premises to the nearest infected premises was the factor most strongly associated with case status. Case premises were more likely than control premises to be within 5 km and beyond 10km of an infected premises. Having a footbath in place on the premises before any horses were infected was associated with a nearly four-fold reduction in odds of infection (odds ratio = 0.27; 95% confidence interval: iv 0.09, 0.83). This protective association may have reflected overall premises biosecurity standards related to the fomite transmission of equine influenza: there was high correlation amongst several, generally protective, variables representing personal ‗barrier hygiene‘ biosecurity measures (hand-washing, changing clothes and shoes, and having a footbath in place). The movement of infected horses and local disease diffusion were known to be important mechanisms of spread early in this outbreak. A network analysis was conducted to investigate the relative contribution of each mechanism. The relationship between infected and susceptible horse premises (contact through animal movements and spatial proximity) was described by constructing a mixed transmission network. During the first 10 days of the 2007 equine influenza…

There is a well documented decline in exercise capacity, immune function, insulin sensitivity and hypothalamic-pituitary-adrenal axis function in aged horses. Aerobic training can partially reverse age-related declines in performance measures, endocrine and immune function, and insulin sensitivity in horses. The mechanisms behind the adaptive response to exercise in horses require further research. Based on the comparative literature, several mediators of energy homeostasis and adaptation to exercise were identified for investigation in whole blood and skeletal muscle of horses. Young and aged unconditioned Standardbred mares underwent an acute submaximal exercise test. Plasma cortisol, insulin and glucose concentrations were determined pre- and post-exercise. Whole blood and gluteus medius biopsies were analyzed for gene expression of inflammatory cytokines, HSP70 and HSP90 pre- and post-exercise. Skeletal muscle was also analyzed for protein content of HSP70, HSP90, AMPK, Akt and AS160 pre- and post-exercise. Exercise increased plasma cortisol concentration in both young and aged mares, with the duration of the post-exercise rise in cortisol altered in aged horses. Although the magnitude of the insulin response to exercise was not different between young and aged horses, plasma insulin was elevated sooner and declined earlier in aged mares. Subsequently, aged mares had a shorter duration of elevated plasma glucose concentration post-exercise than young mares. Exercise increased IL-β expression in whole blood of young and aged mares, with young mares having greater exercise-induced expression of IL-β. Cytokine expression was not altered in skeletal muscle, regardless of age or exercise. Young and aged horses had increased HSP70 expression in whole blood following exercise, with young horses exhibiting greater exercise-induced HSP70 expression. HSP90 expression in whole blood following exercise was increased only in young horses. HSP70 and HSP90 expression in skeletal muscle was increased following exercise in both young and aged horses, with age altering the timing of HSP70 expression. There were no changes in skeletal muscle protein content of HSP70 and HSP90; or in activation or total protein concentration of AMPK, Akt and AS160, due to exercise or age. In conclusion, mediators of energy homeostasis and the adaptive response to exercise are altered with age in horses.

▼ The primary aim of this study is to reduce the reliance on Artemia during the culture of pot-bellied seahorses. The results demonstrate that reliance can be reduced significantly if not totally replaced. Early juvenile seahorses can be fed on alternative live diets such as copepods as the growth (F = 0.054, df 1, p > 0.05) and condition (F = 0.416, df 1, p > 0.05) of 3-week old seahorses fed copepods was similar to those fed enriched Artemia. It was also found that seahorses as young as newborns readily consumed copepods and gammarid amphipods (Hippomedon sp and Biribus sp) from the biofouling panels. Later juveniles can continue to be fed on biofouling crustaceans as the growth (F = 0.982, df 1, p > 0.05) and condition (F = 7.401, df 1, p < 0.05) of 17-week old seahorses fed biofouling was similar to those fed Artemia or weaned onto frozen diets. The best predictor for determining prey size was the total length of the seahorse. Based on Cheeson's standardised forage ratio the preferred prey type of 5, 21 and 49 day old seahorses showed a particular preference for copepods with 21 and 49 day old seahorses also positively selecting both amphipod species (Hippomedon sp and Biribus sp). Larger 147 and 175-day old seahorses positively selected both amphipod species and 203-day old seahorses' positively selected Biribus sp and caprellids (Caprella sp). Thirteen week old seahorses were weaned onto either a frozen mysid or amphipod diet with a nil, 10 day and 16 day weaning period and it was found that the growth of seahorses weaned onto frozen diets over a 16 day period had similar growth (F = 83.922, df 7, p < 0.05) to those seahorses fed enriched Artemia. It is possible that younger seahorses could be weaned onto frozen diets if appropriate sized feeds can be attained. It was also found that although a range of commercial enrichment diets had no affect on the growth (F = 0.671, df 5, p > 0.05) and condition (F = 1.637, df 5, p > 0.05) of seahorses, Artemia should be enriched as the liver condition in seahorses fed unenriched Artemia was poor and the optimal feed rate for seahorses was between 5 and 7 % body weight daf1 (F = 0.47, df 5, p < 0.05). This study also examined the anatomy of the digestive system and ontogenetic development of digestive enzymes to provide a better understanding of the potbellied seahorses' nutritional requirements and digestive capacity. Seahorses are released with a near fully developed digestive tract and could be said to be fully developed between day 21 and 35 after the intestinal valve develops on day 7 and the intestine starts to loop around itself on day 21. Trypsin, lipase and amylase were present at every stage studied. The presence of enzymes in unfed newborn seahorses indicates that they are capable of digesting protein, lipid and carbohydrates prior to the onset of feeding, however the digestive system may not be fully functional until around day 28 to 35 when enzyme activities appeared to plateau. It was also found that trypsin and lipase …

▼ The objective of this study was to evaluate relationships among genetic and physiological biomarkers and phenotypic characteristics in horses. Three breeds (Quarter Horse, Thoroughbreds, Miniatures), and five genes of interest (leptin, ghrelin, cytochrome P450, glucocorticoid receptor, and lactate dehydrogenase) were the basis of the investigation. Genomic DNA was extracted from buffy coat samples of Quarter Horses (n = 21), Thoroughbreds (n = 26), and Miniatures (n = 34). Data were analyzed using MIXED MODEL procedures of SAS, with the main effects of breed and SNP genotype. Horse was the experimental unit, and dependent variables were classified as physical, cell differentials, and blood components. When the main effect F-test was significant (P < 0.05), means were separated using multiple T-tests. We identified three single nucleotide polymorphism (SNP) sites in the leptin gene of horses (A326G, C481T, A580G), one SNP site in ghrelin (T176C), one SNP site in cytochrome P450 (T556G), one SNP site in glucocorticoid receptor (T90C), and two SNP sites in lactate dehydrogenase A (A371T, G399T). Body mass index (HT/BW) and body weight for mares who were homozygous guanine at leptin A326G were highest (P < 0.05) of all genotypes identified. Monocytes, as a percentage of white blood cells, were increased (P < 0.05) for mares that were homozygous guanine at T556G. At SNP site A371T homozygous thymine mares were the tallest (P < 0.05) of all genotypes. Results from this study suggest that polymorphisms associated with leptin, ghrelin, cytochrome P450, glucocorticoid receptor and lactate dehydrogenase genes could be used as genetic markers for phenotypic traits in horses as well as indicators of the overall health and wellbeing of the animal. These results indicate a further need for research in this area, which could lead to better recommendations for managing horses with diverse body conditions and could lead to selecting horse with overall increased fitness.

▼ Respiratory conditions causing poor performance in horses are usually as result of upper respiratory tract diseases or are of pulmonary origin. The tracheal is rarely a cause of primary respiratory problems in the horse, but tracheal dimensions, particularly height, may be useful in evaluating upper repiratory tract conditions cranial to the trachea and lung pathology, due to resultant change in differential pressures between these areas. The normal radiological equine tracheal height along its length has as yet not been reported. Standing lateral radiographs of the cervical and thoracic trachea of 15 clinically normal sedated Thoroughbred horses, 3-6 years old, were made at peak inspiration and end expiration. Maximum height of the larynx, and trachea at the level of the third and fifth cervical vertebra, at the level of the first thoracic vertebra, carina and the left and right primary bronchi were measured. Ratios of laryngeal height relative to the third cervical vertebral body length and tracheal heights relative to the vertebral body lengths of adjacent third and fifth cervical vertebrae and first thoracic vertebra, and carina heights relative to a mid-thoracic vertebra, respectively were made, as well as tracheal height at the fist thoracic vertebra ratio with the thoracic inlet height. Known size metallic markers were used to determine magnification corrected tracheal heights in the sagittal plane and effect of body mass and height at the withers on tracheal height was determined. The magnification corrected radiological airway heights at end expiration and peak inspiration were measured and respectively the mean values were found to be: laryngeal height: 5.89 cm and 5.86 cm, tracheal height at the third cervical vertebra: 4.17 cm and 4.04 cm, tracheal height at the fifth cervical vertebra: 3.62 cm and 3.59 cm, tracheal height at the first thoracic vertebra: 3.4 cm and 3.23 cm and carina height: 3.85 cm and 4.12 cm. The ratios of these measurements to nearby vertebral body lengths were respectively: laryngeal height at the third cervical vertebra: 0.56 and 0.56, tracheal height at the third cervical vertebra: 0.4 and 0.39, tracheal height at the fifth cervical vertebra: 0.37 and 0.37, tracheal height at the first thoracic vertebra: 0.59 and 0.59, and carina height: 0.91 and 0.94. The ratio tracheal height at the first thoracic vertebra to the thoracic inlet respectively 0.15 and 0.15. Although there was no statistical difference in the data, there was a trend towards a higher tracheal height at expiration. No correlation was found between tracheal height and body mass or tracheal height and height at the withers, and measured tracheal height was generally lower than predicted tracheal height, possibly as result of sedation used. The small range of body mass and height in this study as well as the relatively small number of horses evaluated may account for the lack of correlation to predicted tracheal height. This study in normal horses may serve as a reference when radiologically evaluating cases of upper… Advisors/Committee Members: Prof R M Kirberger (advisor).

▼ The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dollars are spent maintaining captured horses in holding facilities awaiting adoption. To manage the feral horse population, the BLM is seeking a contraceptive that is safe, can be remotely delivered, requires only a single administration and is effective for several years. Contraceptive strategies have been developed for feral horses that include hormone implants, chemical intrauterine devices, and immunocontraception. Porcine zona pellucida (pZP) immunocontraceptive vaccines have shown great potential for providing safe, long-term contraception in feral horses. ImmunoVaccine Technologies (Halifax, Nova Scotia, Canada) has developed a liposome encapsulated pZP formulation known as SpayVac™ (SpayVac), which after a single-dose provides multi-year contraceptive efficacy. In a continued effort to optimize the acceptability and efficacy of SpayVac, ImmunoVaccine Technologies developed alternative adjuvant preparations using either killed Mycobacterium butyricum (Modified Freund's Adjuvant; MFA) or a proprietary non-Mycobacterium based adjuvant (IVT) that are proposed to have less of the undesirable side-effects associated with Mycobacterium tuberculosis. Therefore, the objective of this research was to evaluate SpayVac in different adjuvant formulations for efficacy of contraception as measured by pZP titers and estrous cyclicity in treated mares. Domestic mares (n=28) were randomly assigned to four treatments (7 mares per treatment): adjuvant alone or saline (Control) or SpayVac vaccines in one of three adjuvant preparations: IVT or MFA in either an aqueous (MFA aq) or non-aqueous (MFA non-aq) suspension. Pre-immune blood samples were collected from each mare and mares were injected in the neck with a single injection of the Control or SpayVac. Subsequent blood samples were collected at weekly intervals for 26 weeks. Sera were analyzed for pZP titers and progesterone using ELISA. At the conclusion of the study, ovaries were recovered by ovariectomy (16 mares) or at necropsy (12 mares) for histologic analysis and collection of morphometric data and oocytes. Titers for pZP were greater (P<0.05) in IVT and MFA mares compared to Control mares and for MFA compared to IVT mares. Mares vaccinated with MFA aq had greater (P<0.05) pZP titers at 2 weeks post-injection compared to mares injected with IVT or MFA non-aq and at 3 weeks post-injection compared to mares injected with IVT. MFA non-aq mares had greater (P<0.05) pZP titers at 6 weeks post-injection compared to IVT mares and, although not significantly different, titers in MFA non-aq mares remained greater during weeks 8, 10, 14, 18 and 22 compared to IVT and MFA aq mares. Mean serum progesterone concentrations were greater (P<0.05) in Control compared to MFA non-aq mares. Mean ovarian weights, oocyte diameters, zona pellucida thicknesses and the number of… Advisors/Committee Members: Menino, Alfred (advisor), Mason, Robert (committee member).

▼ The general aim of this study was to address questions on early juvenile Hippocampus abdominalis husbandry posed by research and commercial ventures. Experiments assessed the effect of tank colour, temperature, salinity, stocking density, photoperiod and substrate on survival, growth and Artemia ingestion of cultured juveniles. Seahorses are visual feeders; experiments tested the effects of eight background colours (black, blue, green red, orange, yellow, white and clear) and three photoperiods on prey intake and growth. Ten minute observations and growth trials indicated no significant differences among treatments. Seahorses improved growth in 16:08 (L: D) compared to constant light and 08:16 (L:D). Seahorses under continuous light did not improve growth despite continuous feeding opportunity. A subsequent study on adults indicated that H. abdominalis produces elevated levels of plasma melatonin during the scotophase and low levels in the photophase. The aquarium trade in seahorses is primarily focused on tropical species. To assess the adaptability of H. abdominalis to tropical conditions, the effect of four temperatures (17, 20, 23 and 26 °C) on juvenile survival and growth was investigated in two 6-week experiments. Seahorse growth was higher at 20 and 23 °C than 17 °C while 100% mortality occurred at 26 °C. The availability of space in seahorse culture depends on the availability of the attachment substrate in addition to free tank space used during swimming and forgaing. The effect of different stocking-densities and substrate preferences on H. abdominalis was examined. Four stocking densities (45, 30, 15 and 5 juveniles 3 `1^-1`) were tested on newborns over six weeks. A second experiment aimed to remove the mortality effect experienced during the first experiment using 21-day-old fish to test three stocking-densities (25, 15 and 5 juveniles 3 `1^-1`). There were no significant differences between treatments in both trials. Juveniles were provided with three choices in substrate diameter (0.17, 0.55, 0.90 mm) and mesh-density (5, 10 and 24 mm in bar-length, giving high, medium and low mesh density). Newborns and 28-day-old seahorses displayed preference for larger diameters and low mesh-density. Commercial facilities culturing H. abdominalis occasionally experience reduced salinities during seasonal rainfall runoff. To determinate the adaptability of this species to low salinities, juveniles were direct- and gradual-transferred from 32 ppt to salinities do iii to 5 ppt. Juveniles grew and survived in a range of 32 to 15 ppt while 5 ppt produced 100 % mortality. From the study, the environmental conditions which potentially promote optimal juvenile growth and survival are a temperature of 20 °C, a salinity of 20 ppt, a stocking density of 5 seahorses r and a photoperiod of 16:08 (L:D). The information from this study identifies the baseline for future research protocols and provides scientific information on the husbandry of If. abdominalis juveniles that can be applied to commercial culture.

▼ Residual osteochondral debris represents a clinical problem associated with arthroscopic debridement and curettage of joint surfaces. At the Oregon State University Veterinary Teaching Hospital (OSU-VTH), during a period from January, 1983 to August, 1986, incidence of radiographically recognizable osteochondral debris in the carpal joints of postarthroscopic equine patients was excessive. Uncertainty exists regarding the fate and effects of this debris on the normal equine joint. Reports in human medical literature implicate osteochondral debris as both an inflammatory stimulus and a mechanical abrasive in the pathogenesis of osteoarthrosis. This study was designed to evaluate the fate and effects of surgically implanted autogenous osteochondral fragments, intended to mimic remaining operative debris, on various physical and biochemical parameters of normal equine middle carpal joints over a six month time period. Four autogenous osteochondral fragments, removed from the lateral trochlear ridge of the talus, were arthroscopically placed as loose bodies into a randomly selected middle carpal joint in each of 10 young horses (2 to 4 years old). The contralateral middle carpal joint, subjected to a sham procedure, served as control. Postoperative therapy was consistent with usual treatment of clinical arthroscopic patients. Lameness evaluation, radiographic examination, carpal circumference measurement, and synovial fluid analysis were performed preoperatively and at scheduled intervals postoperatively. After two months of confinement, the horses were subjected to an increasing level of exercise, intended to mimic a four month conditioning program. Animals were euthanatized at 1 month (1), 2 months (2), 4 months (1), and 6 months (6). Gross and microscopic examination of remaining fragments, articular cartilage, and synovial membrane of each middle carpal joint was performed. Clinically, increased joint circumference, effusion, lameness, and radiographic appearance of degenerative joint disease distinguished implanted from control joints over the six month period. Implanted joints were grossly characterized by grooved, excoriated cartilage surfaces and synovium which was thickened, erythematous, and irregular. Loose bodies became adhered to synovium at their subchondral bone surface within four weeks after placement into the joint. At four weeks, bone within fragments was undergoing necrosis, while cartilage was preserved. At eight weeks, fragments were radiographically inapparent, grossly evident as pale plaques on the synovial surface, and composed of dense fibrous connective tissue. Histologically, synovial membrane specimens from implanted joints demonstrated significant (P < 0.05) inflammatory change two months after implantation. Mononuclear cells infiltrated the synovial layers. Significant physical damage (P < 0.05) was apparent within the articular cartilage two and six months after surgery. Chondrocyte degenerative change was significant (P < 0.05) six months after… Advisors/Committee Members: Scott, Edward A. (advisor), Pearson, Erwin (committee member).

▼ Intravenous regional limb perfusion (IVRLP) with tiludronate is a commonly used treatment for distal limb orthopedic disease in horses, but doses and protocols are anecdotal. IVRLP exposes articular cartilage within the perfused area to tiludronate, raising concerns about safety of this treatment, as high tiludronate concentrations (≥19mg/L) were harmful for cartilage in vitro. This is the first study to evaluate synovial fluid tiludronate concentrations following IVRLP to determine safety for articular cartilage in horses. Synovial fluid cytology variables and tiludronate concentrations were evaluated in the navicular bursa, coffin and fetlock joints following IVRLP of one front limb with low dose (0.5mg, n=6) or high dose (50mg, n=6) tiludronate. The contralateral limb was perfused with saline as a control. Synovial fluid samples were taken 1 week prior and 30 minutes following IVRLP from all structures and 24 hours post-perfusion from coffin and fetlock joints. Synovial fluid tiludronate concentrations were lower in limbs perfused with 0.5mg in all synovial structures (metacarpophalangeal joint = 3.7 ± 1.5 mg/L, distal interphalangeal joint = 16.3 ± 1.9 mg/L, navicular bursa = 6.0 ± 1.9 mg/L) than in limbs perfused with 50 mg (metacarpophalangeal joint = 0.04 ± 0.02 mg/L, distal interphalangeal joint = 0.12 ± 0.06 mg/L, navicular bursa = 0.08 ± 0.03 mg/L) at tourniquet release. Only limbs perfused with 50mg had tiludronate detectable in synovial fluid 24 hours post-perfusion. There were no significant differences in synovial fluid cytology variables between samples from limbs perfused with saline vs. tiludronate. Thus, perfusion with tiludronate at doses used did not cause synovial inflammation in comparison to saline control limbs. Cytology variables did increase over time in both treated and control limbs, suggesting that IVRLP and/or synovial fluid sample acquisition stimulates an inflammatory response within synovial structures. Doses of 0.5mg or 50mg of tiludronate given via IVRLP resulted in synovial fluid concentrations that can be considered safe for articular cartilage based on previous in-vitro data. Tiludronate concentrations in bone should be explored to determine safety for bone and possible treatment efficacy for orthopaedic diseases of the distal equine limb.

▼ Digestion of non-structural carbohydrates (NSC) from cool season pasture grasses can result in increased adiposity, insulin resistance, and laminitis in horses. Lowering blood glucose levels and increasing insulin sensitivity can reduce disease risk. Supplementing horses with psyllium reduces blood glucose and insulin concentrations in meal fed horses. The objective of this study was to evaluate the effects of psyllium supplementation in horses grazing rapidly growing cool season grass. Eleven lightbreed stock horses (7 mares, 4 geldings, Age 13.5 + or - 2.5; mean + or - SD) were individually confined in dry lots overnight and strip grazed for 8 hours daily for 30 days. Psyllium-supplemented horses (n = 6) received 180 g of psyllium daily. All horses received an isocaloric protein supplement. Forage intake was calculated using a previously published equation based on bodyweight. Forage was analyzed for nutrient content every other week. Changes in metabolic characteristics were assessed by assay of glucose, insulin, leptin and adiponectin concentrations in blood samples collected on days 0, 8, 15, 22, and 29 at 0700, 0800, 0900, 1100, 1300, and 1500 hours. Changes in morphometric characteristics were assessed using bodyweight, body condition score, mean neck circumference, and tailhead fat mass on days 0 and 29. Significance accepted at P < 0.05. Psyllium supplementation lowered mean glucose, glucose AUC and increased time to peak glucose. There was a treatment by gender interaction for mean insulin, peak insulin, and insulin AUC. These variables were lowered to a greater extent in geldings than in mares. Higher NSC intake resulted in higher peak insulin in all horses. Older horses had higher peak insulin and decreased time to peak glucose and insulin. All characteristics of glucose and insulin decreased over the 30 day interval spent grazing pasture. Mares had higher leptin concentrations. Adiponectin concentrations increased with NSC intake. No significant differences occurred for morphometric characteristics. These results indicate that supplementing psyllium in horses grazing cool season grasses lowered systemic glucose and insulin concentrations and these effects may reduce the risk of metabolic diseases, such as laminitis. However, systemic glucose and insulin concentrations were affected to a greater extent in males than females. Advisors/Committee Members: Chairperson, Graduate Committee: Shannon Moreaux (advisor).
