Topic:Animal Science
Animal Science and horses encompass the study of equine biology, physiology, and management practices aimed at understanding and improving horse health, welfare, and performance. This field integrates various scientific disciplines, including genetics, nutrition, reproduction, and behavior, to address the needs of horses in diverse contexts such as sports, work, and companionship. Research in this area often focuses on optimizing feeding strategies, enhancing breeding programs, and developing effective health management protocols. Additionally, studies explore the genetic factors influencing traits such as athleticism and disease resistance, as well as the impact of environmental and management conditions on horse behavior and welfare. This page gathers peer-reviewed research and scholarly articles that investigate the scientific principles underpinning equine science and their practical applications in horse care and management.
A contribution to the D system in horses. The inheritance of a new D system red cell antigen, factor 22, is described. It has also been possible to discriminate more efficiently between D system phenogroups enabling genotypes to be identified from phenotypes in the majority of cases. This improves the accuracy of animal identification and gene frequency estimates.
A preliminary report on an attempt to modify behavior of untamed ponies by acupuncture. A preliminary study using various acupuncture techniques to modify behavior of untamed ponies was attempted. In five of the seven tested parameters, the animals's behavioral responses were unaffected by acupuncture treatments. However, substantial improvement of general behavior of the nervous ponies was observed in animals treated with jaw and scutiform points. The results are not conclusive and further testing of acupuncture as a mean of modifying animal behavior is desirable.
Equine marker genes: Polymorphism for soluble erythrocyte malic enzyme. Polymorphism of equine erythrocyte malic enzyme is detactable on starch gel electrophoresis. The frequency of ME1S was 0.06 in 667 Standardbred and 0.09 in 85 Thoroughbred horses. No genetically determined electrophoretic variation in soluble malate dehydrogenase was detected.
Coat color and gestation length in thoroughbred mares. Average gestation periods for bay, chestnut, dark bay, gray, and black Thoroughbred mares were compared. A total of 1359 gestation periods were used. A linear model including factors for age of mare, sex of foal, month and year of breeding, and sire effects was used in the analysis. Dam and sire coat-color combinations were also investigated in a similar manner. No significant differences in gestation length could be attributed to coat color of the mare of to dam and sire coat-color combinations. Heritability of gestation length was estimated to be 0.38. The results of this study strongly sugg...
Copper metabolism and requirement in mature ponies. The effects of copper intake on stable copper and 64Cu metabolism and on the excretory pathways of absorbed copper were examined in ponies. Bile and feces collected from two bile duct-cannulated ponies following an intravenous dose of 64Cu showed that bile was the main route of endogenous copper excretion. Stable copper and 64Cu metabolism were examined in three intact ponies fed dietary copper to provide 5.6, 16.6 and 25.7 mg Cu/100 kg body weight/day. The amount of copper excreted in urine was not influenced by dietary treatment. Stable copper absorption and 64Cu retention significantly incr...
Fatty acid composition of equine plasma. Fatty acid composition of plasma lipids of normal horses was determined. Four fatty acids (C16:0, C18:0, C18:1, and C18:2) comprised 86.73% of the total, with C18:2 comprising 44.04% of the total. Eight other fatty acids were found in small amounts. Unsaturated fatty acids constituted 66% of the total. Marked variation was demonstrated in fatty acid occurrence and distribution in the sterol ester, triglyceride, phospholipid, and free fatty acid fractions.
Characterization of the binding of Triton X-100 to equine and rabbit serum albumin. The binding isotherms for Triton X-100 binding to equine and rabbit serum albumin were determined by equilibrium dialysis at 16 degrees C in pH 7.0, I = 0.05 phosphate buffer. Presented in a Scatchard plot, the binding isotherms are a straight line, indicating thermodynamically independent and identical binding sites. In this model equine serum albumin is characterized as having 11 such sites with an equilibrium constant of 6.0 x 10(3) M-1. Similarly, rabbit serum albumin is characterized as having 9 such sites with an equilibrium constant of 8.0 x 10(3) M-1.
Influence of season and age on reproductive activity in pony mares on the basis of a slaughterhouse survey. Reproductive tracts were collected monthly over a 3-year period from 1,003 nonpregnant ponies at a slaughtering plant in Wisconsin. Ages of the animals were estimated from tooth replacement and wear. Ovaries were examined for follicular and luteal activity. There were no differences between left and right ovaries in size or occurrence of ovulation. The frequency of multiple ovulations, 10%, was higher than previously reported for ponies. The follicular changes during the ovulatory cycle did not support a two-wave theory of follicular growth. Ovarian activity changed seasonally, a finding simil...
A critical efficacy test of cambendazole in equids: the use of the geometric means to assess efficacy. The anthelmintic efficacy of a 44.5% paste formulation of cambendazole was evaluated in a critical trial performed on 5 horses and a donkey. A dosage of 20 mg/kg showed reduction of mean parasite burdens as follows: Strongylinae greater than 99%; Cyathostominae 94%; immature and adult Oxyuris equi 89 and greater than 99%; Probstmayria vivipara greater than 99% and Habronema muscae 97%. Parascaris equorum and Anoplocephala perfoliata were present in small numbers in individual animals only, and while all were removed by treatment, the small numbers did not justify calculation of a percentage ef...
