Pig Litter Management and Welfare in Neonatal Piglets

How neonatal piglet welfare is shaped by litter management, colostrum access, sow management and early intervention protocols.

Key Facts

Pre-weaning mortality in commercial pig production averages 12–15% globally — the majority occurring in the first three days of life
Causes include crushing by the sow (overlaying), starvation from competition for teats and chilling from hypothermia
Piglets are born with minimal fat reserves and are highly vulnerable to chilling — maintaining temperatures above 32°C is critical
Large-litter breeding has increased piglet number beyond the sow's teat capacity, creating competition and starvation risk
Fostering piglets between sows of similar farrowing dates is a standard management practice to balance litter sizes
Split suckling and supervised nursing sessions are welfare-protective interventions for very large litters

Welfare Considerations

Neonatal piglet welfare is a high-stakes welfare management challenge played out on an enormous scale — millions of piglets die in the first week of life annually in commercial pig production. Many of these deaths involve days of cold, hunger and weakness before death — not instantaneous loss. The selection pressure for hyperprolific sows — producing 15–18 piglets per litter — has created a structural welfare problem: litter sizes that exceed the sow's teat number create inevitable competition, and the smallest, weakest piglets — already at greatest risk — lose that competition and die. Welfare improvement requires attention to both the individual piglet and the systemic breeding pressure that has pushed litter size beyond the bounds of natural teat capacity.

What You Can Do

Provide heat lamps or heat pads positioned correctly to maintain creep temperature above 32°C without overheating the sow
Ensure all piglets receive colostrum within the first 6 hours of life — assist small or weak piglets to suckle if necessary
Foster piglets between sows of similar farrowing dates to balance litter sizes to the number of functional teats
Use split-suckling to allow smaller piglets exclusive nursing access to colostrum before larger littermates
Increase stockperson supervision during the farrowing period — most crushing occurs in the first 24–48 hours
Review sow selection decisions with your breed advisor — hyperprolificacy selection beyond teat capacity creates inherent welfare costs
