Weight variation within pig litters creates welfare challenges as smaller piglets struggle to compete for teat access. Management strategies that reduce this competition improve survival and welfare outcomes.
Size variation within large litters creates a welfare crisis for the smallest piglets from the moment of birth. These animals face immediate, intense competition for milk access in a biological system that does not protect the weakest - quite the opposite. Starvation and hypothermia from lack of milk intake are among the most common causes of piglet death. The suffering involved in failing to obtain milk and slowly dying over hours to days is significant. Management interventions that give smaller piglets better access to nutrition genuinely improve welfare by converting otherwise fatal situations into survivable ones. These interventions require labor investment but represent meaningful welfare improvements for animals that would otherwise suffer and die.
