Resumo
The objective of this work was to evaluate the digestibility of sorghum (Sorghum bicolor) or
millet (Pennisetum glaucum) diets with the addition of a commercial enzymatic complex formed by amylase,
carbohydrases, proteases and phytase, and broiler performance. For performance evaluation, 1,800 male
broilers were distributed in a randomized complete block design in a 2x2 factorial arrangement, with four
treatments (sorghum or millet diet with or without addition of enzymatic complex), and five replicates of
60 birds per experimental unit. In the metabolism assays carried out at 10 to 14 and 24 to 28 days, 420 male
broilers were distributed in a completely randomized block design in a 2x2 factorial arrangement (millet or
sorghum diet with or without addition of enzymatic complex). Data were submitted to variance analysis and
averages were compared by the F test for orthogonal contrasts. In diets formulated with sorghum, the addition
of the enzymatic complex provided better coefficients of digestibility of fat and nitrogen. The addition of the
enzymatic complex in diets formulated with sorghum improves feed conversion ratio only in the initial phase
of raising broilers, while the addition of the enzymatic complex does not improve broiler performance in diets
formulated with pearl millet.
