Body condition scoring in breeding sows provides a measurable welfare indicator that reflects nutritional management, housing quality, and reproductive pressure on individual animals.
Sow body condition reflects the cumulative welfare impacts of reproductive pressure, housing restrictions, feeding management, and social competition over years of production life. A sow with chronically poor body condition is experiencing ongoing nutritional stress, likely lameness, and compromised ability to nurse piglets effectively. The welfare implications cascade: thin sows produce weaker piglets with lower survival rates, creating welfare problems in the next generation. Body condition scoring offers a practical, observable welfare measure that farmers and auditors can use to identify problems before they become severe. The challenge is that structural features of intensive production — high litter numbers, gestation crates, competitive feeding — make good body condition difficult to maintain systematically.
