This study was conducted to determine the best age (T1-21, T2-28, T3-35 days old) of weaning of piglets and to determine the profit above feed, medicine and stock cost. It was conducted from September 3, 2011 to December 8, 2011, at the Piggery Project of Don Mariano Marcos Memorial State University, North La Union Campus, Bacnotan, La Union. Nine sows were distributed at random into three (3) treatments following the Randomized Complete Block Design (RCBD) in three blocks. The result of the study revealed that the weaning ages of piglets did not significantly affect the final weight of the piglets at 45 days old, average daily gain, feed consumption, feed conversion ratio, profit above feed, medicine, and stock cost and number of days to estrus. However, the weaning weight of piglets was significantly affected by the weaning ages of the piglets.en-USThesis
