The first days of a piglet's life are the highest-mortality period and among the most welfare-significant. Management of the farrowing environment, colostrum access, and temperature control are critical welfare determinants.
Neonatal piglet welfare is shaped by the intersection of reproductive biology, housing design, and stockpeople skill. A large litter born to an exhausted sow in a cold farrowing crate, where the sow cannot assist struggling piglets and where stockperson rounds are infrequent, will have high mortality and significant welfare compromise for surviving individuals. A smaller litter born to a well-nourished sow in a loose farrowing system with warm creep areas, skilled stockpeople monitoring, and access to nest-building material will have far better welfare outcomes. The first days of life also shape behavioral development: piglets that experience positive early handling, appropriate sensory stimulation, and successful suckling develop better welfare outcomes throughout the growth period. Investment in neonatal welfare is investment in lifetime welfare.
