Biomedical applications of sheep models: from asthma to vaccines

Although rodent models are very popular for scientific studies, it is becoming more evident that large animal models can provide unique opportunities for biomedical research. Sheep are docile in nature and large in size, which facilitates surgical manipulation, and their...

Behavior and welfare of the sheep

The most important features of the behaviour of sheep are their marked sociality and the bond formation between mother and young. Sheep show a strong need to stay with their group (or subgroup for some breeds), and become very vocal...

Influence of space allowance and housing conditions on the welfare, immune response and production performance of dairy ewes

The experiment used 45 Comisana ewes, divided into 3 groups of 15. The aim was to determine the effects of two different stocking densities and two different housing conditions on welfare, and on production performance of dairy ewes. The stocking...

Feeding, resting and social behaviour in ewes housed in two different group sizes

The aim of this experiment was to investigate the effects of increased group size on eating- and resting behaviour, aggression and feed intake in housed ewes. During an initial period of 14 days 36 adult (2–6 years old) ewes of...

Effect of individual or paired housing during post-weaning on feed intake, growth rate and behaviour of lambs

The aim of this study was to compare the behaviour and weight gain of weaned lambs penned either in pairs or alone, with visual and tactile contacts between pens. A 2 × 2 factorial experiment was conducted over seven weeks....

Social buffering of the stress response: Diversity, mechanisms, and functions

Protracted or repeated activation of the hypothalamic–pituitary–adrenocortical (HPA) system is associated with a variety of physical and psychological pathologies. Studies dating back to the 1970s have documented many cases in which the presence of a social companion can moderate HPA...
