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...

Effects of handling and transportation on the heart rate and behaviour of 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...

The effect of space allowance and sex on blood catecholamines and cortisol, feed consumption and average daily gain in growing lambs

Reducing the [barren] space allowance from 0.99 to 0.62 sq.m per lamb reduced feed intake and average daily gain. .. There was no effect of pen size on plasma epinephrine, norepinephrine or cortisol concentrations. .. The results show that the...
