Increased Space Allowance Improves Productivity and Welfare in Growing Pigs Assessed Using Artificial Intelligence-Based Monitoring of Agonistic Behavior
This study demonstrates that increasing space allowance from 0.57 to 0.97 m²/pig significantly improves growth performance, feed efficiency, behavioral welfare, and physiological stress status in growing pigs. Pigs housed under low rearing density (LRD) exhibited higher body weight, greater feed intake, and improved feed conversion ratio, accompanied by reduced agonistic behavior, lower ear and tail lesion scores, and decreased metabolic and endocrine stress markers. The integration of AI-based behavioral monitoring provided novel insights into temporal patterns of social interactions and injurious behaviors, highlighting rearing density as a key management factor for productivity and welfare.

Increased space allowance alleviated physiological stress and reduced injury.
Real-world Impact: Reduced Social Stress
The study observed that pigs in low rearing density maintained greater inter-individual distances, reducing conflict frequency. This behavioral modification, captured by continuous AI monitoring, directly correlated with significantly lower lesion scores, demonstrating improved group stability.
Challenge: High rearing densities intensified social competition, leading to increased agonistic behaviors like ear and tail biting, resulting in injuries and compromised welfare.
Solution: Increasing space allowance from 0.57 m²/pig to 0.97 m²/pig significantly reduced the frequency and duration of agonistic behaviors, alongside lower ear and tail lesion scores.
Result: Pigs in low rearing density consistently exhibited lower ear base temperatures and reduced plasma cortisol, indicating a profound reduction in physiological stress and enhanced overall well-being. This translates to improved growth rates and feed efficiency.
