Cribbing (horse)
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Cribbing is a type of vice (bad habit) developed by horses. It involves the horse grabbing a solid object, such as the stall door or fence rail, with his incisors, arching his neck, pulling against the object, and sucking in air. Like most vices, cribbing is thought to cause the release of endorphins in the horse's brain, causing a sensation of pleasure. It has recently been determined that the horse does not actually swallow the air, as was once thought, and air does not collect in the animal's stomach.

Causes
Cribbing is usually caused by boredom. It is therefore seen most often in horses that are stalled for long periods, or horses kept in fenced areas with poor pasture. Once a confirmed habit, the horse may crib in other places, such as out in a grassy field.

Problems with Cribbing
Cribbing can harm both the horse and the stable. Horses wear down the incisors faster than the teeth can grow out, leading to erosion of the teeth and malocclusions, which can take years to correct. Tooth problems can lead to other, more serious, complications such as colic.
Cribbing is extremely damaging to the stable. Horses will oftentimes wear down their stall doors and fence rails.

Prevention
A confirmed cribber is difficult to stop. Most horsemen rely on a cribbing collar but they are not always affective [1], which fits around the throat of the animal, just behind his cheekbone. The collar usually has an adjustable leather strap, to control the tightness, as well as a metal piece that goes under the throat. This piece prevents the horse from arching his neck, making cribbing difficult. A cribbing collar must be fit very snuggly to allow it to work correctly, although many horses will still crib with the collar on. Cribbing muzzles may also be used, as the horse can not grab anything with his teeth, but may still drink and graze without difficulty.
Wood fences may be protected from a cribber by running a strand of hot wire around it. It is also possible to paint the fence with a distasteful substance, to discourage a cribber from grabbing it in his mouth.
However, it is always best to never give the horse a chance to develop the vice, either by providing plenty of turn-out, or giving him something in his stall to interest him, such as hay or stall toys.
Actually, the best thing you can do about any stable vices is simply letting your horse to fulfill his natural needs. This can be achieved quite easily, just by letting him to be outside with other horses. Horses simply need to socialize with other horses. Cribbing is a sign of the horse's suffering from isolation.
Brake the Habit - - This takes Time but…
I would put a cribber in a stall – I had a bracket I could hang on a stall dore with a disk blade hanging on it… If the horse started anybad Habits I'd shoot the disk-blade with a BB Gun or through a rock at it… My Aussie would see this and soon earned to jump-up on the stall door if her saw a horse Cribbin or stall weaven
I hung a road-cone from the roof for the horse to play with.
