ESR9: Improving the survival and growth of piglets from large litters: manipulation of colostrum and milk, and provision of supplemental milk

Increased litter size in sows is linked with decreased piglet birth weight (BtW) and reduced neonatalRelating to newborn individual. survival. The number of underdeveloped piglets born to these large litters is increased, resulting in some piglets showing signs of Intra-Uterine Growth Restriction (IUGRIntra-uterine growth retardation, is defined as the impaired growth of the fetus or its organs durin…).
