Degradação ruminal e síntese de proteína microbiana em bovines alimentados com silagem de sorgo contendo tanino suplementado com concentrado ou uréia

This work aimed to determine ruminal parameters of dry mater (DM), neutral detergent fiber (NDF) and protein synthesis in the rumen of animals fed diets based on sorghum with different tannin levels. In situ degradation was evaluated by rumen incubation of level 1 (L1) and level 2 (L2) sorghum silages during 0, 6, 24, 48 and 96 hours. A duplicated 4 × 4 Latin Square was used. Potential degradability (PD) of DM was similar among silages, whereas the effective degradability (ED) decreased when the diets were supplemented with concentrate. Microbial nitrogen flux and microbial synthesis efficiency were not affected by roughage source. The synthesis efficiency, expressed in organic matter and crude protein digested in rumen, was higher in L1 tannin diets supplemented with concentrate. There was not relationship between the presence of tannins and the parameters of ruminal degradation.
