TOTAL AND DIGESTIBLE AMINO ACIDS FORMULATION OF BROILER FEED USING DIFFERENT SOYBEAN MEAL

Abstract

A feeding experiment has been conducted to evaluate different soybean meal fi'om USA, India and Iatin America in ration formulated using total and digestible amino acids from broiler. One thousand five hundred chicks (Arbor Acre male) were divided into 6 treatments in a factorial design (3 different sources of soybean meal and 2 methods of formulation) and 5 replicates containing 50 birds replicate pen. Dietary treatments were fonnulated using oom and soybean meal as major ingredients. At 21 days, body weight was significantly affected by different
soybean meal; USA soybean meal gave the highest body weight (559 g) followed by India soybean meal (540 g) and Latin America soybean meal (515 g). Daily feed consumption was not affected but feed/gain were 1.655, 1.669 and 1.766 for USA, India and Latin America, respectively. However, at 42 days only body weight gain were affected but not feed/gain or feed consumption. Formulation using digestible amino acid was significantly better than total amino acid on body weight and feed/gain but not on feed consumption. Body weight was 27-29 gram higher and feed/gain was improved about 7 point at 21 days of age.
