Evidence for early dispersal of domestic sheep into Central Asia

Nature Human Behaviour, 2021
The development and dispersal of agropastoralism transformed the cultural and ecological landscapes of the Old World, but little is known about when or how this process first impacted Central Asia. Here, we present archaeological and biomolecular evidence from Obishir V in southern Kyrgyzstan, establishing the presence of domesticated sheep by ca.

The eye of the domesticated sheep with implications for vision

Animal Science, 1996
AbstractThe eyes of eighteen female sheep (Ovis aries) were refracted and details of inter ocular distance, pupil size, shape and fundus presence recorded. The sheep eyes generally possessed very low hyperopia with little astigmatism, such physiological optics being expected to produce a well focused retinal image for objects in the middle and long ...

Origin and Significance of Centric Fusions in Domestic Sheep

Journal of Heredity, 1976
The karyotypes of 731 sheep of various breeds were studied and considered in association with previous chromosome studies of domestic sheep. A high incidence of the t2 trnslocation was found in two pedigree flocks of New Zealand Romney sheep. One of these flocks was established over 100 years ago and it is suggested that this translocation originated ...

Seroprevalence of Toxoplasma gondii in domestic sheep in Belgium

Veterinary Parasitology, 2014
Even though infected sheep are a potential source of Toxoplasma gondii infection in humans, information is lacking concerning the seroprevalence of T. gondii infection in sheep in Belgium. We examined 3170 serum samples for anti-Toxoplasma IgG in sheep by total lysate antigen (TLA) enzyme-linked immunosorbent assay (ELISA). IgG to T.

Lynx Depredation on Domestic Sheep in Norway

The Journal of Wildlife Management, 2002
We studied depredation rates on free-ranging domestic sheep (Ovis aries) by Eurasian lynx (Lynx lynx) in 2 areas in Norway to test whether selected individuals or a demographic group within a lynx population kill a disproportionate share of livestock.

PASTEURELLA SPP. IN SYMPATRIC BIGHORN AND DOMESTIC SHEEP

Journal of Wildlife Diseases, 1997
Domestic 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.
