Does maternal deprivation affect a calf’s physiological and behavioral reactions to later stress? Journal of Animal Science 70(Supplement 1), 162 (Abstract)

Calves separated from their dams at 21 days of age were found to show a significantly higher stress response [cortisol, heart rate] to later stress than those left with their dams until weaning.

Consistent stress response of individual dairy cows to social isolation

Stress response in pairs of cows after separation from partner was investigated. Short-term social isolation induced an increase in heart rate, an elevation of plasma cortisol concentration, and increased vocalization.

Stereotypies and cortisol secretion in heifers subjected to tethering

Tethering of heifers after a grazing period lead to increased performance of stereotypies and high plasma levels of cortisol.

Behaviour of dairy cows kept in extensive (loose housing/pasture) or intensive (tie stall) environments

The results suggest that the act of lying down in the [tie] stalls was aversive to the cows [relatively high incidence of knee and hock inflammations] and that the lying area [concrete floor] and/or the tie-stall system increased the risk...

Abnormal oral behaviours in fattening bulls: incidence, causation and implications

Abnormal oral behaviours, such as tongue playing and nibbling at objects or at coat, tail and ears of penmates, are common in fattening bulls housed on fully slatted floors and fed intensively. .. Half of the groups were fed with...

Individual variation in response to stressors in farm animals: Implication for experimenters

Several ways of reducing stress during experiments are suggested and the need for skillful and humane handling is emphasized. .. Any modification of the handling procedure aimed at reducing its stressful nature would be beneficial. .. It is concluded that...

Put away your prod: herd stock with less stress by understanding how they think

Low-stress animal handling not only results in higher animal performance but also less stress and greater personal satisfaction for you. To reduce animal stress, you first have to understand how your animals think. You need to know how livestock perceive...
