Elevated Sensitivity to Tactile Stimuli in Stereotypic Horses
TLDR
The analyses showed that crib-biters only differed from control horses in their tactile sensitivity, suggesting an elevated sensitivity to tactile stimuli, and it is suggested that this higher tactile sensitivity could be due to altered dopamine or endogenous opioid physiology, resulting from chronic stress exposition.
Stereotypic horses (Equus caballus) are not cognitively impaired
TLDR
The results of this study challenge the widely held belief that crib-biting horses, and stereotypic animals more generally, are cognitively impaired and conclude that cognitive underperformance may occur in stereotypic horses if they are prevented from crib- biting to cope with experienced stress.
Effects of breed, management and personality on cortisol reactivity in sport horses
TLDR
No significant associations of cortisol responsiveness with personality traits were found, and neither the use as elite or as amateur sport horses nor the discipline had an effect on the cortisol response, suggesting that optimizing husbandry conditions may be more important for improving equine welfare than changing their use.
Effects of breed, management and personality on cortisol reactivity in sport horses
TLDR
No significant associations of cortisol responsiveness with personality traits were found, and neither the horses’ use as elite or as amateur sport horses nor the discipline had an effect on the cortisol response, suggesting that optimizing husbandry conditions may be more important for improving Horses’ welfare than changing their use.
Frequency of abnormal and stereotypic behaviors in urban police patrolling horses: A continuous 48-hour study
TLDR
High level of chronic stress, expressed as abnormal and stereotypic behaviors, was observed in the horses.
Understanding oral stereotypies in calves: alternative strategies, hypothalamic-pituitary-adrenal axis (re)activity and gene by environment interactions.
TLDR
This study corroborates the gene by environment interaction on the development of oral stereotypies in calves and confirms that calves with a zero solid feed allowance showed links between stereotypies and two of the PCs.

Plasma cortisol and faecal cortisol metabolites concentrations in stereotypic and non-stereotypic horses: do stereotypic horses cope better with poor environmental conditions?
TLDR
Investigation of correlates of oral and motor stereotypic behaviours and glucocorticoid levels in two large samples of domestic horses found that cortisol measures do not indicate that stereotypic horses cope better, at least in terms of adrenocortical activity.
Behavioural 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

Heart rate and behavioural responses of crib-biting horses to two acute stressors
TLDR
The heart rate and behaviour of 14 adult saddle horses, eight crib-biters and six normal controls, were investigated and it was found that the crib- Biters had a higher overall mean heart rate suggesting that they may haveHad a higher basal sympathetic activity.
Crib-biting behavior in horses: A review
Physiological correlates associated with cribbing behaviour in horses: changes in thermal threshold, heart rate, plasma beta-endorphin and serotonin.
TLDR
The decrease in both heart rate and thermal threshold during cribbing provide evidence that cribbing may reduce stress, and indicate differences in cribber's endogenous opioid and serotonergic systems.
