Chromosomes, Hemoglobins, and Transferrins of Iranian Domestic Sheep
Journal of Heredity, 1976Twelve breeds of Iranian domestic sheep were cytogenetically analyzed. The diploid chromosome number of 2n = 54 is identical to that of most breeds of domestic sheep, which is comprised of 3 pairs of metacentric and 23 pairs of acrocentric autosomes. The sex chromosomes consist of a large acrocentric X and a small bi-armed Y.

Pathology of AA Amyloidosis in Domestic Sheep and Goats
Veterinary Pathology, 2003We describe the main pathologic changes in small ruminants affected by AA amyloidosis, together with the partial sequence of the protein involved. Twenty-one sheep and one goat were selected for presenting macroscopic kidney lesions compatible with systemic amyloidosis.

The role of unconscious selection in the domestication of sheep and goats
Journal of Zoology, 1998AbstractIt is proposed that many of the morphological, physiological and behavioural traits that characterize domestic sheep and goats and distinguish them from their wild ancestors (e.g. diminished sexual dimorphism; diminution in brain, body and horn size and changes in shape of the horns; changes in pelage coloration) were shaped, to a large extent,

Domestication and bone structure in sheep and goats
Journal of Archaeological Science, 1975Some time ago now it was suggested that there were important structural differences between the bones of wild and domestic animals (Drew et al., 1971a). It was claimed that there were differences, firstly, in the orientation of the crystals of bone mineral, secondly, in the X-ray diffractometer patterns from bone slices and, thirdly, in the size of the

Pharmacokinetics and sedative effects of intramuscular medetomidine in domestic sheep
Journal of Veterinary Pharmacology and Therapeutics, 2003Intramuscular (i.m.) administration of medetomidine (MED) may avoid the severe pressor effects caused by peripheral actions of MED associated with intravenous (i.v.) dosing. The purpose of this study was to determine the pharmacokinetics, the time course of sedation and occurence of hypoxaemia after i.m. administration of MED in domestic sheep. The MED

Retinal Photoreceptor Fine Structure in the Domestic Sheep
Cells Tissues Organs, 1983The structure of the photoreceptors of the domestic sheep has been investigated by light and electron microscopy. In the sheep retina the photoreceptors are readily differentiated and adequately described by the classical terminology of rods and cones. Rods are more numerous then cones. They appear as tall slender cells measuring 45–50 µm in length and

A New Species of Coccidia from Domestic Sheep
The Journal of Parasitology, 1952While engaged in research on members of the genus Eimeria infecting Wyoming sheep, an undescribed species was observed. The parasite was recovered from two of nine animals housed at the Wyoming State Veterinary Laboratory at Laramie, Wyoming. Both animals had multiple infections; oocysts of Eimeria airloingi, E. ah-sa-ta, E. parva, E.
