Sow Body Condition and Welfare in Pig Production

Maintaining appropriate body condition in sows is critical for welfare, reproductive performance and longevity in commercial pig production.

Key Facts

Sow body condition score reflects energy reserves affecting reproduction and welfare
Over-fat sows have increased farrowing difficulties while thin sows have poor milk production
Group housing in gestation makes individual feeding and condition monitoring challenging
Electronic sow feeding systems can improve individual nutrition management
Poor body condition is a key reason for premature culling of sows

Welfare Considerations

Sow body condition directly reflects welfare quality throughout the production cycle. Thin sows experience chronic undernutrition affecting their physical condition and behaviour. Over-conditioning leads to metabolic problems and farrowing difficulties with welfare impacts on both sow and piglets. The competitive dynamics of group housing can make equitable feed access difficult without electronic systems.

What You Can Do

Advocate for electronic sow feeding systems that enable individual nutrition
Support farmers in implementing body condition scoring protocols
Promote welfare-based culling criteria that prevent extreme condition loss
Choose pork from welfare-assured herds with documented sow welfare monitoring
Support research into optimising sow nutrition in group housing systems
