Resumo: | Abstract The objective of this study was to evaluate the effects of different levels of digestible lysine, at fixed amino acid ratios, in performance, blood parameters and diet digestibility of barrows from 15 to 30 kg. Fifty barrows of the Duroc breed with an average initial body weight of 14.95±3.22 kg were assigned to five treatments in a completely randomized experimental design with five replicates and of two animals per experimental unit. Treatments consisted of crude protein and lysine levels, maintaining a fixed ratio with the other digestible amino acids (8.4, 9.4, 10.4, 11.4, and 12.4 g kg–1lysine/kg of diet). The feed conversion decreased linearly according to lysine levels. The apparent digestibility coefficients of dry matter and crude protein increased linearly, and the same response was observed for serum total protein and urea. The results indicate that digestible lysine level for Duroc barrows in the starter phase is 12.4 g kg–1 of diet, as it improved feed conversion ratio and apparent nutrient digestibility. |
