Body condition scoring of breeding sows is a simple but powerful welfare tool that detects nutritional problems before they become serious, yet many commercial pig operations fail to monitor body condition systematically.
Body condition monitoring is a low-cost, high-value welfare practice because it detects nutritional problems before they cause serious harm. A sow with a body condition score of 1.5 is experiencing chronic nutritional deprivation that compromises immune function, reduces milk production for her piglets, and causes long-term muscle damage. Without systematic scoring, thin sows may go unnoticed in large group systems until their condition becomes critical. The data generated by electronic feeding systems in group housing creates an unprecedented opportunity for individual animal welfare monitoring at scale, but this opportunity is only realized when producers actively use the data for welfare management decisions.
