Abstract

The present study was conducted in the swine production sector of the Animal Science Department of the Federal University of Lavras (UFLA), MG, aiming to verify the performance and carcass characteristics of pigs in finishing phase fed diets formulated with true digestible amino acids values for the same levels of lysine and the other amino acids and the same relation lysine:metabolizable energy. The experimental treatments consisted of four diets: 1 – corn and soybean meal, 2 – corn, soybean meal, cottonseed meal and peanut meal, 3 corn, soybean meal, meat and bone meal and fish meal, 4 – sorghum, defatted rice bran and soybean meal. In the performance trial, 64 commercial hybrid barrows means 61.82 ±3.10 kg of live weight housed in pairs in pens which constituted the experimental units allocated into a completely randomized block design were utilized. The carcass characteristics was evaluated on one pig of each pair, means 92.81 ±2.09 kg according the Brazilian system of carcass classification (ABCS, 1973). No effect (P>0,05) was observed on the feed intake, weigth gain, performance of carcass, back fat, meat percentage and relation fat/meat in any of the treatments evaluated.. It was observed a better gain feed ratio for the treatment 1. It was concluded that the use of diets formulated with true digestible amino acids values for the same levels of lysine and other amino acids and same relation lysine:metabolizable Energy for pigs in finishing phase is technically feasible.
