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...

Lack of Adaptation to Repeated Emotional Stress Evoked by Isolation of Sheep from the Flock

The aim of this study was to examine whether sheep can adapt to emotional stress evoked by individual isolation from the flock. The experiments were performed on 12 sheep divided into 2 groups; the control (kept in the sheepfold) and...

Modification of the responses of sheep to isolation stress by the use of mirror panels

Isolated sheep showed considerable interest in the mirror but no other behavioural differences were found. Plasma cortisol levels were increased by isolation and were significantly higher during the 'no mirror' condition. .. Plasma prolactin concentrations were low and rather variable,...

Voluntary acceptance of restraint by sheep

Training technique is described and documented with a photo to make sheep to be voluntarily restrained in a tilt squeeze table for a grain reward. All sheep movements from the crowd pen into the race and squeeze tilt table were...

Behavioral principles of livestock handling

Reducing stress during handling will improve productivity and prevent physiological changes that could confound research results or lower productivity. Handling stresses lower conception rates and reduces both immune and rumen function. Handlers who understand livestock behavior can reduce stress. Livestock...
