Summary
Human-directed aggression is common in pet pigs. Having another pig in the household significantly reduces aggression, suggesting companionship is key for pet pig behavior management.
Area of Science:
- Veterinary Behavior
- Animal Welfare
- Pet Husbandry
Background:
- Human-directed aggression is a frequent concern in pet pig ownership.
- Understanding factors influencing aggression is crucial for owner-pig relationships and pig welfare.
Purpose of the Study:
- To investigate associations between human-directed aggression in miniature pet pigs and factors including sex, neutering status, weaning age, presence of other pigs, and environmental enrichment.
Main Methods:
- An internet survey was administered to 222 owners of miniature pet pigs.
- The survey collected data on pig demographics, social environment, enrichment, and aggressive behaviors.
Main Results:
- Aggression was reported in 64% of pigs; frequent aggression occurred in 31%.
- No significant associations were found with sex, neutering status, weaning age, or environmental enrichment.
- Pigs housed with at least one other pig showed significantly less frequent and less common aggression.
Conclusions:
- Human-directed aggression is prevalent in miniature pet pigs.
- The presence of a conspecific (another pig) is a significant protective factor against aggression.
- Promoting social housing may be an effective strategy to mitigate aggression in pet pigs.
