Stereotypic behaviour in cattle signals unmet welfare needs. Understanding common stereotypies and their causes enables welfare improvements in dairy and beef systems.
Stereotypic behaviours in cattle — repetitive, invariant motor patterns that serve no apparent function — indicate that the animal has been unable to cope with its environment. Tongue rolling typically develops in young cattle denied adequate roughage, when the oral stimulus of fibrous feed is replaced by repetitive tongue manipulation. Bar biting and licking of fixtures signals frustration and inadequate environmental stimulation. Like stereotypies in other species, those in cattle persist even after conditions improve because the neural pathways become entrenched. Prevention through adequate roughage provision, appropriate stocking density, and environmental enrichment is far more effective than any attempt to treat established stereotypies. Herd-level stereotypy prevalence is a useful welfare indicator in farm audit programs.
