Crib Biting - what is it and should we stop it?
Crib biting - also known as 'cribbing' is a repetitive action seen in some domesticated horses whereby the horse will place their upper incisors (their top front teeth) on a firm object such as the top of a stable door, a metal gate, a wooden fence post, etc, arch their neck and pull back on the object. They usually make an audible grunting noise while doing this. Research has shown that whilst very little air is drawn in during this behaviour, much of it ends up in the upper oesophagus, rather than travelling down the gastrointestinal tract.
We often see horses with this behaviour and some horse owners are worried that it is detrimental to their horses' health.
The habit is still relatively misunderstood but it is now believed to be a coping-mechanism born from stress, anxiety or other management factors within the horse's environment.
There are some common factors in horses that crib bite, including lack of enrichment, long periods in their stables, not enough forage, too much hard feed versus forage, lack of social interaction/direct contact/socialisation with other horses, gastrointestinal discomfort, trauma during weaning, boredom and stress.
Should horse owners try and prevent the horse from crib biting? We do see issues linked to crib biting, such as colic, loss of condition, insufficient intake of forage whilst grazing (due to the horse standing cribbing for long periods of time), gastric ulcers (it is still unclear if cribbing is the cause of ulcers or if the horse is cribbing because it has ulcers), worn-down incisors and head pain (specifically linked to Temporohyoid osteoarthropathy), not to mention damage to the items the horse cribs on.
If your horse shows signs of ill health linked to crib-biting, contact your vet and assess the management of your horse. Your vet may also suggest referring your horse to an Equine Behaviourist.
