Resumo: 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 x 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.

A degradação in situ foi avaliada por meio da incubação ruminal de silagens de sorgo contendo nível 1 (N1) e nível 2 (N2) de tanino por 0, 6, 24, 48 e 96h. O delineamento experimental utilizado foi o quadrado latino 4 x 4 duplicado. Os valores de degradabilidade potencial (DP) da MS foram semelhantes entre as silagens, enquanto a degradabilidade efetiva (DE) nas silagens foi reduzida ao adicionar concentrado à dieta. O fluxo de nitrogênio microbiano e a eficiência de síntese de proteína microbiana não foram afetados pela fonte de volumoso. Houve maior eficiência de síntese, expressa em relação à matéria orgânica e energia bruta digeridas no rúmen, nas dietas com silagem N1, quando as dietas foram suplementadas com concentrado. Não foi possível estabelecer relação consistente entre a presença de taninos e os parâmetros de degradação ruminal.Editora da Universidade Estadual de Maringá2009-05-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/50210.4025/actascianimsci.v31i1.502Acta Scientiarum.
