The objective of this study was to evaluate the in situ effect of two commercial enzymes on the digestibility and kinetics of the dry matter sugarcane bud (Saccharum officinarum). The sugarcane bud was dried at 65°C for 48 hours, ground with a 3 mm sieve, and incubated for 30 minutes with the Allzyme Vegpro ® enzymes (T1), and the Rovabio Excel ® enzyme (T2). The enzymes were used at 1% of the body weight. The substrate without treatment was considered the control treatment (T0). It was used a randomized experimental design, with four periods, three treatments (T0, T1 and T2), and two replicates for treatment period. The samples were weighing (1.8 g), imputed in dracon bags and placed alpaca 1 compartment. The bags were removed after digestion in different hours (6, 12, 24, 48, 72, and 96), proceeding to the wash and then drying and weighing. The parameters evaluated in digestion kinetics were: initial digestibility, degradable fraction, degradation rate, potential digestion and average time. The results were analyzed using two-way ANOVA and Tukey's test is used to mean multiple differences. This study showed that digestibility in situ dry matter (ISDMD) did not improve. It was found only small differences (p<0.05) at 6, 12 and 48 hours but without biological significance. There were no differences among treatments (p>0.05) for initial digestibility, degradation rate, potential digestion and the average time, but there was difference (p<0.05) in the degradable fraction between T1 vs. T0 and T2. It is concluded that in the used dose fibrolytic enzymes do not increase digestibility or kinetics of digestion of the sugarcane bud (Saccharum officinarum). Key words: Enzyme fibrolytic, sugarcane bud, in situ digestibility, Alpaca
