Crib-biting in horses is a stereotypical oral behaviour with a prevalence of 2.8–15%. Factors such as stress, gastric discomfort and frustration caused by stall restrictions has been suggested as a causal basis. Our hypothesis was that crib-biting is a quantitative trait with a moderate heritability (h2), because there is some anecdotal evidence that the trait is expressed in certain families. Our aim was to test the associations of known or suspected stereotypic genes with equine crib-biting and estimate the heritability of crib-biting behaviour in a Finnhorse population. Data on a cohort of crib-biting and non-crib-biting (control) privately-owned horses were collected during 2009–2013. Controls were at least 10 years of age and without a history of crib-biting. A candidate gene study with a case-control design was performed, including 98 crib-biting and 135 control horses of two breeds, Finnhorses and half-breds...
