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.
Isoenzymes of equine alkaline phosphatase. Alkaline phosphatase isoenzymes from small intestine, cecum, large colon, small colon, liver, kidney, leukocytes, and serum from ten clinically normal horses were defined by their sensitivities to L-phenylalanine, L-homoarginine, levamisole and heat, and by polyacrylamide gel disc electrophoresis. Readily identifiable isoenzymes occurred in small intestine, granulocytes, kidney, cecum, and large and small colon. By contrast, alkaline phosphatases from liver, lymphocytes, and serum could not be discriminated by this group of tests.
[The proportion of aerobic and anaerobic metabolism in horses during graduated physical loading]. Changes in the concentration of lactate in the blood are described as a response to gradated physical strain, consisting of 1140 m of walk, 2 x 1000 m of trot, and 3 x x 5000 m of gallop in seven horses in thirteen experiments. The dependence of lactate concentration on speed in different track sections was examined and the aerobic and anaerobic stages of metabolism were clearly differentiated. It appears realistic on the basis of the onset and course of anaerobic metabolism to work out tests for evaluating the physical capacities and training abilities of horses.
Treatment of fear-induced aggression in a horse. Desensitization (gradually exposing an animal to a fear-inducing stimulus without evoking the fear response) and counter-conditioning (rewarding the animal for behavior incompatible with the fear response) are highly successful ways of eliminating or reducing fear responses and corresponding aggression.
A technique for the conduct of nutritional balance experiments in horses. Standardbred geldings were used in a number of nutritional balance experiments. These consisted of 28-day cycles each of an 18-day equilibration period in yards and a 10-day settling and collection period in metabolism crates. The crates were made of galvanised metal tubing over wooden flooring covered by rubber matting and rubber sheets. Total faeces were collected in trays at the rear of crates and total urine by canvas funnels slung beneath the sheath of each horse.
Ossifying ameloblastoma in a horse. The features of an ossifying ameloblastoma in a 5-year-old gelding are described. The tumour developed in the angle of the right mandible and microscopically consisted of multiple follicles and islands of epithelial tissue adjacent to which were trabeculae of bone, osteoid and compact collagenous tissue.
Lipoproteins as substitutes for serum in Mycoplasma culture medium. Crude lipoprotein-containing fractions obtained from sera of three different animal species were tested, in combination with bovine serum in Mycoplasma pneumoniae culture medium. All sera yielded at least one lipoprotein-containing component which was considerably more effective in promoting mycoplasma growth than the unfractionated serum sample from which it was derived. The very low activity of certain whole-serum samples tested in this investigation suggests that toxic substances may be present in whole serum which are not contained in the lipoprotein preparations. The greatest activity app...
A survey of early pregnancy losses in West German thoroughbred mares. Embryonic resorption is reported as the main reason for early pregnancy losses in the West German Thoroughbred mare. An analysis of breeding records for the last 11 years showed a resorption rat of 8.4 per cent. Evidence was obtained that these early embryonic losses were associated with too early conception after foaling and with the state of lactation.
Assessment of myocardial function in the horse. 1. Theoretical and technical considerations. The paper discusses the various parameters which are currently used in attempts to assess the contractile efficiency of the myocardium in various species. These procedures depend upon accurate recording of intracavity pressure. The response of a catheter-mounted microtransducer compared with a fluid-filled catheter manometer system is illustrated to show the advantage of the former in providing a true representation of pressure changes.
Horse markings: their importance to the integrity of racing and breeding. The difficulties that arise in filling out marking certificates for thoroughbreds are described. The description given on the certificate has to be both written and graphic. A general guide to whorl location is given.
