Effects of confinement stress on episodic secretion of LH in overiectomized sheep

Episodic secretion of luteinizing hormone (LH) in ovariectomized ewes was evaluated before and during acute confinement and during several days of habituation to the same confinement. Plasma concentrations of LH were quantified in samples collected at 5-min intervals via indwelling...

Behaviour of sheep transferred from pasture to an animal house

Sheep kept for long periods in [single] pens had many stereotypic behaviour patters. .. perhaps caution is needed to extrapolate results from nutritional and physiological traits in pens to sheep at pasture.Sheep kept in individual pens develop locomotor stereotypies, including...

Aversion of sheep to electro-immobilization and physical restraint

Thirty-six Merino wethers were forced along a sheep race and were either electro-immobilized using a commercially-available instrument, restrained with the electro-immobilizer electrodes attached, physically restrained in a sheep-handling machine or allowed to run freely through the race. The degree of...

The use of space by group-housed sheep

Quality of space as well as quantity affects the use of the space by the animals and so must also be considered in housing design.

A note on the behaviour of individually-penned sheep regarding their use for research purposes

Sheep are commonly housed in small individual pens for research purposes. ... The nature and extent of the abnormal behaviour found may be indicative of a differing background physiological state in these experimental animals from those in most common practical...

Effects of management procedures on heart rate in sheep

Sheep show a marked increase in heart rate when isolated from other sheep. When a sheep was separated from other sheep by a fence, she stayed calm as long as she could see her companions. However, if the fence was...
