The effect of sorghum treated with an enzyme of Aspergillus niger glucoamilase on animal performance and microbial population, was evaluated in 20 lambs pelibuey males with an average age four months and a weight of 23.5 ± 3 kg, animals were distributed in individual metabolic cages at random in two treatments : T1 without enzyme (SE) and T2 enzyme (EC), the research lasted 74 days divided into five periods of 15 days each, the enzyme product used was Glucozyme®, which was dosed at a rate of 10 mL kg-1 of sorghum milled. Productive variables that were assessed were: dry matter consumption (CMS), daily gains (ADG) and feed conversion (CA), and microbiological variables were: pH of ruminal fluid, ruminal concentrations of total bacteria and protozoa. The statistical analysis of production variables was carried out using a t-Student for independent samples, while for the concentration of bacteria and protozoa was statistically analyzed using comparison of means. The average CMS was not statistically different between treatments, the average GDP was statistically different (p ≤ 0.05) between treatments (210.60 vs 243.89 g) for T1 and T2 respectively, the concentration of bacteria and protozoa were not significantly different (p > 0.05) between treatments.
