Research Abstract

Suckling piglets are weaned forcibly at 3 or 4 weeks old in Japan. Weaning are almost considered the convenience of sows, less considered the sufficiency of nutrition or good growth of neonates, previously. Recently, some viral diseases prevail, and its infection deteriorates ferocity in pig industry. Therefore, weaning age is reconsidered to prevent the viral infection for the improvement of pig management. On the other hands, suitable weaning age of neonate is not examined yet particularly in matching the Japanese pig industry. Therefore, I determine the suitable weaning age for neonates from the points of view of nutrition, gene expression, immune and pathology. According the results, weaned at 14 days old is too early, weaned at 21 days old or more is needed to their subsequent healthy development.
