Changes in plasma cortisol and ?-endorphin concentrations and behaviour in sheep subjected to a change in environment

With prolonged chronic stress, such as confinement in metabolism crates, cortisol is depressed below baseline values.

Effects of differential handling on the behaviour of domestic ewes (Ovis aries)

Thus it appears that unforced handling of sheep results in decreased avoidance behaviours, characterized by a greater willingness to approach and contact humans.

Fetal and maternal body temperatures measured by radiotelemetry in near-term sheep during thermal stress

Using implanted radiotelemeters, we have measured amniotic temperature and fetal lamb and pregnant ewe body temperatures continuously over the last 34 days of gestation and during conditions of thermal stress. Body temperature of the fetus was approximately 0.6 degrees C...

Confinement of lambs (Ovis aries) in metabolism stalls increased adrenal function, thyroxine and motivation for movement

The results of the present study indicate that lambs maintained in metabolism stalls can be physiologically and behaviourally altered [even though they appear to have all of their physical needs met, they have no opportunity for locomotion, grazing, or physical...

The effect of isolation and separation on the metabolism of sheep

Individually housed sheep are restless and show an increased heart rate which may persist over many days and account for an increased metabolic rate of up to 15%.
