Topic:Animal Species
The topic "Animal Species and Horses" explores the interactions and relationships between horses and various other animal species. This includes understanding the ecological roles horses play within their environments, as well as their interactions with domestic and wild animals. Research in this area may cover aspects such as competition for resources, symbiotic relationships, and behavioral influences between horses and other species. Studies may also investigate the impact of horses on biodiversity and ecosystem dynamics. This page compiles peer-reviewed research studies and scholarly articles that examine these interspecies relationships, focusing on the ecological, behavioral, and environmental implications of horses interacting with other animals.
In vitro synthesis of immunoglobulin-A by salivary glands from animals of different species. The synthesis of immunoglobulins by the salivary glands from eight different species was studied. It has been demonstrated that salivary glands from the cow, horse, sheep, pig, rat and guinea-pig preferentially synthesize a fast migrating immunoglobulin which seems to be analogous to IgA. In three of the species, the cow, sheep and pig, the IgA-like component cross-reacts with human IgA. The IgA synthesized by the salivary glands from the rat cross-reacts with the mouse IgA. When one compares the salivary IgA from the cow, horse, sheep, pig and rat with the IgA synthesized by the lymph nodes,...
Metabolism of immunoglobulin-G in the horse. The metabolism of immunoglobulin classes has been closely examined in several animal species. Although the horse has received much attention in experimental and applied immunology there seems to be little information available on immunoglobulin kinetics in this species. The present report describes the metabolism of equine IgG in 4 healthy, normoimmunoglobulinaemic horses, in 1 horse with hyperimmunoglobulinaemia and in 1 horse with relatively low immunoglobulin levels.
A comparison of fingerprints of tryptic digests of human, horse and rat apoferritins. 1. Fingerprints of tryptic digests of apoferritins from a human liver, horse spleens and ACI rat livers were made by means of electrophoresis and chromatography on microcrystalline cellulose, and were compared.
2. All tryptic peptides also present in apoferritins from the human liver and the horse spleens were also present in apoferritin from the rat livers.
3. In the digests of horse and of rat apoferritin there was a peptide that was not present in the digests of human apoferritin. Another peptide was obtained from human and from rat apoferritin, but not from horse apoferritin.
4. T...
Comparison of digestion in horses, ponies, rabbits and guinea pigs. A comparative digestion trial was conducted between horses, ponies, rabbits and guinea pigs. Alfalfa and alfalfa-grain diets were compared.
Although there was a trend for ponies to be more efficient than horses in digesting proximate principles of both diets, differences were not significant. Digestibility coefficients for crude fiber and energy were lowest in rabbits. The digestion of nitrogen-free extract (NFE) was greatest in guinea pigs, whereas digestion of crude protein was lowest.
Horses, ponies and rabbits digested organic matter, NFE and energy in the mixed ration more efficient...
