Abstract

This research-internship aimed to learn the basics principles, disciplines, and skills in research. Students were given 100 hours to be tobserve and perform the different farm and laboratory techniques done at the Department of Animal Nutrition, CAFS, UPLB such as external egg quality and internal egg quality determination, calcium analysis, feed mixing, sample weighing, feed mixing, and excreta collection. A mini-study was then conducted to determine whether the energy requirement in digesting alpha-galactosidase in corn-soybean pig diets have an effect on the Digestible Energy (DE) and Metabolizable Energy (ME) concentration on the soybean meal. Nine (9) growing pigs (PIC L337xC24) were blocked by their initial weights (60 kgs) and were randomly assigned to the 3 dietary treatments with 2 replications following Youden Square Design. The treatments are: Ti :basal diet with 94.89% corn; T2:70% of the basal diet and 30% soybean meal; and T3:70% of the basal diet and 30% soybean meal with supplementation of a-1,6- galactosidase enzyme complex. Treatments were fed for 2 periods with 10 days per period and the feces and urine collected at day 6-10. Fecal samples from the same treatment were pooled, oven-dried, and grounded while the urine was preserved in 50m1 of 6NHC1. The fecal and urine samples were analyzed in duplicate for GE using bomb calorimetry (Model 6200 of Parr Industries). Results showed that a-1,6-galactosidase enzyme complex does not have an effect on the DE and ME concentration on the soybean meal fed to growing pigs. Thus, it can be concluded that a-1,6-galactosidase enzyme complex can be used as supplementation to growing pig diets as a way to improve production performance without affecting DE and ME.
