Solving Tail-Biting Problems
From Pork Information Gateway. Todd See gives an overview of the environmental, management and nutritional causes of tail-biting.
Outbreaks of tail-biting occur in intensive pork production when a pig bites or chews on another pigs tail leading to a wound and bleeding. This abnormal social behaviour is usually associated with deficiencies in the pigs environment, management or nutrition.
Picture: National Pork BoardTo solve a tail-biting problem promptly remove and treat the tail-bitten pig(s). Then review the following questions and determine the most likely causes. If tail-biting continues check other likely causes until the problem disappears.
Environmental Causes of Tail-Biting
Is the building temperature appropriate for the age and weight of the pigs?
Is the ventilation system functioning properly?
Are pigs following appropriate dunging behavior?
Is the building air quality (ammonia and hydrogen sulphide levels) satisfactory?
Are pens dry?
Management Causes of Tail-Biting
Are pigs overcrowded?
Can pigs lie comfortably?
Has mixing of pigs between pens occurred?
Is the electrical supply properly grounded and stray voltage eliminated?
Nutritional Causes of Tail-Biting
Was the feed properly formulated for levels of salt and other vitamins and minerals?
Are there a sufficient number of drinkers with adequate flow rate per pen?
Is there adequate feeder space?
