Topic:Animal Studies
Animal studies involving horses encompass a range of research focused on understanding equine biology, behavior, and health. These studies often investigate various aspects of horse physiology, genetics, nutrition, and disease pathology. Researchers utilize animal studies to explore the effects of different treatments, management practices, and environmental factors on horse welfare and performance. The findings from such studies contribute to the development of improved care strategies and health interventions. This page gathers peer-reviewed research studies and scholarly articles that explore the methodologies, findings, and implications of animal studies conducted on horses, providing insights into their application in advancing equine science.
The action of cyanogen bromide on horse-heart cytochrome c and horse-heart myoglobin. 1. The effects of cyanogen bromide on horse-heart cytochrome c and horse-heart myoglobin have been investigated. Cytochrome c yielded four fragments, of which two were haemopeptides. The two colourless peptides had amino acid compositions corresponding to those that are expected, on the basis of the sequence proposed for horse-heart cytochrome c by Margoliash, Smith, Kreil & Tuppy (1961), from cleavage at both methionine residues. Of the two haemopeptides, one was isolated and shown to be that derived from cleavage at only one methionine residue, that nearer to the C-terminus of the peptid...
Sex-Linkage of Glucose-6-Phosphate Dehydrogenase in the Horse and Donkey. Distinctly different electrophoretic patterns of red cell glucose-6-phosphate dehydrogenase were resolved from the hemolyzates of horse and donkey erythrocytes. Examination of their reciprocal hybrids, mules and hinnies, showed that the red cells of female mules and female hinnies contain both horse and donkey G-6-PD; the male mule with an X chromosome from its horse mother contained pure horse G-6-PD, whereas the male hinny with the donkey X chromosome contained pure donkey G-6-PD. These findings on the male reciprocal hybrids suggest X-linkage.
CHROMOSOME COMPLEMENT: DIFFERENCES BETWEEN EQUUS CABALLUS AND EQUUS PRZEWALSKII, POLIAKOFF. The chromosome number of the domestic horse is 2n = 64; different races have the same complement. The chromosomes of two Przewalski's horses (at Catskill Game Farm, New York), presumably ancestral wild horses from Mongolia, are identical: 2n = 66, with more acrocentric and fewer metacentric elements than the chromosomes of the domestic horse. This apparent difference in karyotype may help resolve the questions of "purity" in the relatively few remaining Przewalski's horses. Moreover, these findings are of interest in relation to the apparent fertility of hybrids between these species.
Component acids of mare’s milk fat. The milk fat from 20 mares on pasture and 9 stable-fed mares was analysed. It is richer in C18:3 than the milk of other domestic species. This was especially marked when the mares were on pasture and were not given any grain. Further, mare’s milk fat is rich in fatty acids containing less than 14 carbon atoms in their chains. Das Milchfett von 20 Stuten auf der Weide und von 9 stallgefütterten Stuten wurde analysiert. Es enthält mehr C18:3 als das Milchfett anderer Haustiere. Dieses war speziell ausgeprägt für Stuten die auf der Weide gingen und kein Getreide bekamen. Das Milchfett der S...
