Abstract

The effect of diet with different protein quality and supplemented with CRYSTALLINE AMINO ACIDS on performance, IMMUNE RESPONSE, enzyme activity in the intestinal tissue and LITTER CHARACTERISTICS, using 576 Ross 308 (mixed sex)BROILER CHICKENs, in a 2 × 4 factorial experiment with two experimental diets (high and low protein quality) and fourlevels of CRYSTALLINE AMINO ACIDS (recommended levels, without supplemented CRYSTALLINE AMINO ACIDS, 10 and 15%higher than the recommended levels) in a completely randomized design with eight treatments, six replicates and 12chicks per replicate was investigated. The results of this study showed that, adding CRYSTALLINE AMINO ACIDS at levels of10 and 15% higher than the recommended level to diets containing canola meal and wheat (as low quality proteinsource) caused an increase in performance (P<0. 0001), the number of heterophile and heterophile to lymphocyte ratio(P<0. 001) and decreased the number of lymphocyte (P<0. 01). The treatments with CRYSTALLINE AMINO ACIDS hadn’ tsignificant effect on the enzyme activity aminopeptidase and specific activity of the enzyme in jejunum. Also, addingcrystalline amino acids at levels of 10 and 15% higher than the recommended level in a low-quality diet were notsignificantly affected dry matter, nitrogen and ammonia nitrogen in the litter. According to these results, the use ofcrystalline amino acids higher than the recommended levels in the diets with high quality (as maize-soybean meal)has no effect on the performance of BROILER CHICKENs and is not recommended.
