Pig Lactation Welfare - Sow Needs

Welfare considerations for sows during lactation, including body condition, feed access, and social enrichment.

Key Facts

Lactating sows lose 10-20 kg body condition during a 28-day lactation period due to high energy demands
Inadequate feed access in crated sows causes chronic hunger stress during the energetically demanding lactation period
Sow longevity is strongly predicted by body condition at weaning, connecting lactation welfare to lifetime welfare
Social interaction deprivation for crated sows is absolute, with no ability to exercise social behaviour during lactation
Providing sows choice over feeding timing and amount improves feed intake and body condition during lactation
