Sensory involvement in the mating behaviour of domestic sheep
Animal Behaviour, 1968Abstract Sensory stimuli utilized by both rams and oestrous ewes in partner-seeking activity were examined using deaf, anosmic and blindfolded animals mated with tethered or free partners. The sexual activity of rams was affected slightly by loss of hearing, more by inability to smell and most by loss of vision, but partner-seeking was affected ...

The eye of the domesticated sheep with implications for vision
Animal Science, 1996AbstractThe 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, 1976The 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 ...

Archaeological Evidence of Domestic Sheep in the Namib Desert During the First millennium AD
, 2016Bones of domestic sheep dated to the early first millennium AD are described from the Dâures massif in the Namib Desert. The remains confirm earlier investigations which inferred the acquisition of livestock from indirect evidence in the rock art ...

Seroprevalence of Toxoplasma gondii in domestic sheep in Belgium
Veterinary Parasitology, 2014Even 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, 2002We 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.

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.

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

Y chromosome haplotype diversity of domestic sheep (Ovis aries) in northern Eurasia.
Animal Genetics, 2014Variation in two SNPs and one microsatellite on the Y chromosome was analyzed in a total of 663 rams representing 59 breeds from a large geographic range in northern Eurasia.
