Facial and vocal discrimination in sheep

The ability of sheep,Ovis aries, to discriminate between sheep, humans and other animals on the basis of facial and vocal cues was tested in an enclosed Y-maze. Pairs of faces or voices were presented which had a clear differential significance...

The experimental Animal in Biomedical Research (Vol. II) – Care, Husbandry, and Well-Being: Sheep

Probably more than other species, they [sheep] require social company in order to cope with the circumstances of their domestication and in particular with the confinement under an experimental situation. It therefore follows that, in accommodating these animals for purposes...

Effects of an enriched environment on subsequent fear reactions of lambs and their mothers

From birth to weaning (3 months of age), 20 lambs were reared by their mothers in an enriched environment [colored mobile objects plus human-like figure]. Subsequently, this resulted in reduced fear reactions in the mothers, but not in the lambs.

Influence of artificial rearing on behavioral and immune response of lambs

In conclusion, early separation from the ewe affects humoral immune response and post-separation performance of lambs as a possible consequence of a reduced ability of young animals to cope with emotional and nutritional stresses.

Stress-associated concentrations of plasma cortisol cannot account for reduced lymphocyte function and changes in serum enzymes in lambs exposed to restraint and isolation stress

Lambs were used to evaluate the effect of stress-associated plasma concentrations of cortisol on measures of immune function. Lambs given restraint and isolation stress (RIS) were isolated from visual and tactile contact with other lambs for 6 h on three...

Are faces special for sheep? Evidence from facial and object discrimination learning tests showing effects of inversion and social familiarity

We have previously shown that sheep, like monkeys, have neural circuits within the temporal lobe that respond preferentially to faces. They can also discriminate between sheep, humans and other animals on the basis of facial cues using an enclosed Y-maze....
