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...
