Weaning in mammals is an event of maximum stress that generates metabolic wear with mobilization of nutrients for the maintenance of body homeostasis. Piglets experience decreased feed intake and lower productive performance. The objective of the present study was to evaluate the effect of dietary supplementation of branched-chain amino acids (BCAA) in weaned piglets by measuring productive performance and biochemical blood tests. A total of 16 piglets distributed in four treatments were used: T1 = control 1 (without milk supplement), T2 = control 2 (milk supplement), T3 = milk supplement + BCAA (0.5% form milk supplement composition), T4 = milk supplement + BCAA (1%). The piglets of the four groups presented a similar productive performance in all the variables analyzed: daily weight gain, feed consumption and feed conversion. Regarding blood variables, no statistical difference was found either. BCAA supplementation through feed did not improve productive performance or biochemical variables in piglets weaned at 28 days after 7 days of administration.
