Physiological and behavioral consequences associated with short-term prevention of crib-biting in horses.
Crib-biting in the horse is frequently prevented in the short-term by horse-owners using physical means. Because it has been proposed that crib-biting may function to reduce stress, the effect of prevention of crib-biting and/or eating on the behaviour, heart rate, and plasma cortisol and beta-endorphin concentrations was measured in six crib-biting and six normal horses. When crib-biters were ...
متن کاملBehavioural and physiological responses to an acute stressor in crib-biting and control horses
The responses of eleven pairs of crib-biting and non-crib-biting horses (controls) to an arousalinducing stimulus were studied. Video-observation of the horses revealed that crib-biting horses spent between 10.4 and 64.7% of their stabling time performing the stereotypy. During the first 2 days of an experimental period, the horses were conditioned to receive food from a special bucket. On the ...
متن کاملCrib-biting in US horses: breed predispositions and owner perceptions of aetiology.
REASONS FOR PERFORMING STUDY Crib-biting is an equine stereotype that may result in diseases such as colic. Certain breeds and management factors have been associated. OBJECTIVES To determine: breed prevalence of crib-biting in US horses; the likelihood that one horse learns to crib-bite from another; and owner perceptions of causal factors. METHODS An initial postal survey queried the numb...
متن کاملThe effect of short-term prevention on the subsequent rate of crib-biting in thoroughbred horses.
The results of an experimental study of the motivational consequences of short-term prevention of crib-biting are reported here. Eight test horses wore a cribbing collar for 24 h. This was effective in preventing crib-biting in 6 subjects. Using analysis of co-variance that accounted for baseline differences in crib-biting rate, test horses showed significantly more crib-biting than control hor...
متن کاملThe effect of a feeding stress-test on the behaviour and heart rate variability of control and crib-biting horses (with or without inhibition)
Crib-biting is a form of oral stereotypy affecting 4–5% of horses. Once fixed, crib-biting is difficult to eliminate by behaviour therapy, however, its performance can be inhibited by collar or surgery treatment (modified Forssell’s procedure). Although surgical intervention is widespread, the effects on stress coping in horses have not been studied. In the present study we evaluated changes in...
متن کاملThe physiological consequences of crib-biting in horses in response to an ACTH challenge test.
Stereotypies are repetitive and relatively invariant patterns of behavior, which are observed in a wide range of species in captivity. Stereotypic behavior occurs when environmental demands produce a physiological response that, if sustained for an extended period, exceeds the natural physiological regulatory capacity of the organism, particularly in situations that include unpredictability and...
