Behavior that is:• Repetitive• Invariant form• Appears to have no function.
When does it occur
Inadequate diet or environment.
• Inadequate diet will give oral stereotype behavior.
• Inadequate environment will givelocomotory stereotype behavior.
Possible theory
What could be a possible reason forStereotype behavior:
1. Away of coping.2. Addiction.3. Has a function
Away of coping
Environment or diet not sufficient :STRESS.Stereotype behavior may reduce stress.
• Decrease of stress hormone: cortisol• Increase of endorfine• Decrease of heart rate
Addiction
Endorfine: opiad preduced by the body in stress full situations.The animal getsaddicted to endorfines.
Stereotype horses dosed withnaloxone:opiad antagonist .
• Some decrease of performance• Some no influence
Function
• Activity of bowl reduced.• Endorfine baseline low,compaired to
normal horses• Acidity of the stomage has to be
neurtalised. Saliva is only produced duringchewing.
High Risk• Foals one month after weaning• Weaning management• No social contact• Thoroughbreds, 5- 15% , warmbloods 7%• Discipline, endurance low, dressage and
eventing high• Forage vs concentrates not less 6,8 kg fourage• Frequenties feeding• Time spent out of stable
Stereotype behavior
Management problem.The closer to nature the environment, the
less risk.
• Social• Locomotory• Fourage
