Some gilt attacks on the newborn piglets are non-fatal, while others involve the death and eventual consumption of the piglets by the mother. It is estimated that 50% of piglet fatality is due to the mother sow attacking or unintentionally crushing the newborn pre-weaned animals.[1]
Pigs will sometimes attack other animals, including humans.[3]
Savaging has a negative effect on pig farming. Efforts to eliminate it include additional care and attention to the mother pig. Aggressive behavior may be due to fear, discomfort, and unsanitary conditions.[1] Control of the birthing process and human supervision are the best ways to prevent the mother from eating the young, but cost-effectiveness must also be considered.
Statistics indicate that cannibal mother pigs are usually repeat offenders. Thus, one method of prevention is to avoid use of past-offenders for breeding. Alternatively, placing experienced sows next to first-time mother gilts may discourage aggressive behavior.
Proper diet and nutrition decreases the likelihood of gilt cannibalism. Medication or hormones, such as mysoline, can also be given.
