The genetic diversity and phylogeography of Mexican domestic sheep
Small Ruminant Research, 2020Domestic sheep were introduced in Mexico by the Spanish settlers in the 16th century. Nowadays, Mexico hosts several sheep breeds, adapting and evolving in both farming and traditional livestock production systems and different climate conditions ...

FATAL PNEUMONIA OF BIGHORN SHEEP FOLLOWING ASSOCIATION WITH DOMESTIC SHEEP
Journal of Wildlife Diseases, 1982During 1979-1980 acute fibrinopurulent bronchopneumonia resulted in high mortality or total loss of herds of bighorn sheep (Ovis canadensis) in California and Washington. Contact with domestic sheep occurred shortly before the onset of disease in each case.

From the very beginning sheep keepers (un-)consciously selected animals with traits amenable to life and reproduction in an anthropogenic environment. Over the millennia sheep lineages developed which were adapted to the diverse landscapes and climates ...

Molecular evidence for fat-tailed sheep domestication
Tropical Animal Health and Production, 2011The sheep is one of the most successful and widely spread domestic animals. Archaeological evidence traces the first domestic sheep back to the Near East region around 9,000 years ago. It is also known that soon after, the domesticated sheep started to flow out of the centre of origin and spread all over the ancient world following the expansion of ...

PASTEURELLA SPP. IN SYMPATRIC BIGHORN AND DOMESTIC SHEEP
Journal of Wildlife Diseases, 1997Domestic sheep were sighted at different times from 1991 to 1993 on four Nevada (USA) ranges occupied by bighorn sheep. Nasal and pharyngeal swab samples were collected from both sheep species and cultured to determine if any strains of Pasteurella spp. were shared on range conditions after contact of the two species. Pasteurella spp.

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.

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
