This study was conducted to determine the effect of different levels of enzyme (T0 – pure commercial feeds (control), T1 – 0.5 kg enzyme/ton of feeds, T2 – 1.0 kg enzyme/ton of feeds, T3 – 1.5 kg enzyme/ton of feeds) in the performance of growing finishing pigs. Thirty six heads of three months old crossbred pigs were distributed at random into four treatments replicated three times following the Completely Randomized Design (CRD). The study was conducted at the Piggery Project of Don Mariano Marcos Memorial State University, North La Union Campus, Bacnotan, La Union from September 1 to November 5, 2007. Results revealed that enzyme supplementation on feeds at different levels significantly influenced the performance of pigs on the basis of feed consumption, feed conversion efficiency and gain in weight. However, the mean final weight of the pigs and mean profit above feed, medicine, stock and enzyme cost were not significantly different.en-USThesis
