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.
An equine cryptorchid with testicular and ovarian tissues. Cytogenetic and histological studies were carried out on an intersex horse which was diagnosed clinically as a cryptorchid. Surgery confirmed the horse to be a bilateral abdominal cryptorchid and histological examination revealed ovarian tissue associated with the left epididymis. Chromosome analysis of cultured cells from testicular tissue, ovarian tissue and skin revealed 64-XX and 64-XY make-up, the left gonad containing a greater preponderance of XX cells over XY cells. The external characteristics and behaviour of the horse were indistinguishable from that of a "routine" cryptorchid. Othe...
An investigation into the genetics of ‘wobbler disease’ in thoroughbred horses in Britain. Sixty-seven TB horses in Britain suffering from clinical wobbler disease were divided into 5 groups, based on the presence or absence of pathological lesions and their nature. These groups were compared genetically with a control group of 67 TBs known not to exhibit signs of wobbling. Though analysed for both simple and complex modes of inheritance no evidence of a genetic basis was found in any group. The high breed incidence in TBs may be real or apparent. Considerably more male than female wobblers are reported. Other forms of possibly inherited ataxia in equidae are reviewed and reference ...
The capybara (Hydrochoerus hydrochaeris) as a reservoir host for Trypanosoma evansi. Discovery of two ill horses and three dogs naturally infected with Trypanosoma evansi near an experimental station in the Eastern Plains of Colombia led to a search for reservoir hosts of the parasite. Infection was detected in 8/33 healthy capybaras (Hydrochoerus hydrochaeris), none of the remaining 14 horses, and none of 32 Zebu cattle (Bos indicus), 18 paca (Cuniculus paca) and 20 spiny rats (Proechimys sp.). Contrary to common opinion, the results indicated a carrier state in the capybara. Diagnosis was based on morphology, behaviour in albino rats, and pathogenicity and host range in dome...
[Study of hydrolysis of aminoalcohol ethers, phenol and choline under the action of horse blood serum cholinesterase]. Hydrolysis of ethers of saturated and unsaturated alcohols and ethers, e.g. phenol and choline, under the action of horse blood serum cholinesterase, was studied. The reactivity towards enzymatic hydrolysis is decreased due to a greater length of the chain in the alcohol residue of the benzoic acid aminoethers; at nCH2 = 4 the compound is a poor substrate. An increase in nydrophobicity of the acyl residue of the ether molecule also leads to a decrease in the Vmax and Km values. In case of cholinesterase substrates, an increase in the molecule hydrophobicity results in an increase of its non-pr...
Insulin-, glucagon-, and somatostatin-immunoreactive endocrine cells in the equine pancreas. Equine pancreas was investigated with immunohistochemical methods to study the distribution of endocrine cells immunoreactive to anti-insulin, anti-glucagon, and anti-somatostatin. A-cells demonstrable by anti-glucagon are located in the center of Langerhans islets and frequently in the duct epithelium. Few A-cells are seen associated to acini. Anti-insulin reactive B-cells form a large zone around the center of the Langerhans islets in which some B-cells lie between exocrine cells and others, although few, are located in the duct epithelium. D-cells stained with anti-somatostatin serum form a...
Innervation of the equine hip and stifle joint capsules. The hindlimbs of 3 ponies and 3 horses were dissected. The hip joint capsule was found to receive articular nerve fibers from the femoral, obturator, cranial gluteal, and sciatic nerves. The nerve fibers were distributed to the fibrous joint capsule and associated capsular ligaments. The stifle joint capsule was found to receive articular branches from the femoral, saphenous, obturator, common peroneal, and tibial nerves. The fibers terminated in the joint capsule, fat pad, patellar and collateral ligaments, and the internally situated meniscal and cruciate ligaments.
Titration behavior of individual tyrosine residues of myoglobins from sperm whale, horse, and red kangaroo. The titration behavior of individual tyrosine residues of myoglobins has been studied by observing the pH dependence of the chemical shifts of Czeta and Cgamma of these residues in natural abundance of 13C Fourier transform NMR spectra (at 15.18 MHz, in 20-mm sample tubes, at 37 degrees) of cyanoferrimyoglobins from sperm whale, horse, and red kangaroo. A comparison of the pH dependence of the spectra of the three proteins yielded specific assignments for the resonance of Tyr-151 (sperm whale) and Tyr-103 (sperm whale and horse). Selective proton decoupling yielded specific assignments for Cze...
Alkali-labile oligosaccharides from glycoproteins of different erythrocyte and milk fat globule membranes. Phenol extraction of horse, sheep, cow, pig and human erythrocyte membranes and human milk fat globule membranes gave glycoprotein fractions, all of which were shown by gas chromatography to contain the reduced disaccharide beta-D-galactosyl (1-3)-N-acetyl-D-galactosaminital after treatment with alkaline borohydride. Cow and pig erythrocyte membrane glycoproteins were found however to contain much lower amounts than the erythrocyte membrane glycoproteins of the other species tested. After gel filtration, a tetrasaccharide was isolated from horse and sheep glycoproteins containing the disacchar...
Apparent propagation of the equine infectious anemia virus in a mosquito (Culex pipiens quinquefasciatus Say) ovarian cell line. A tissue culture of Culex pipiens quinquefasciatus Say ovarian cells appeared to support the growth of equine infectious anemia (EIA) virus. Shetland ponies inoculated with 2nd, 7th, 9th, and 11th passages of mediums harvested from infected tissue culture had clinical signs of the disease and became EIA positive on 11, 19, 23, and 43 days after inoculation, respectively.
