Avaliação laboratorial de compostos fibrosos em alimentos e fezes bovinas sob diferentes ambientes físicos

Gomes, D. IDetmann, EValente, T. N. PValadares Filho, S. CQueiroz, A. C

The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents were evaluated in concentrates, forages, and cattle feces using filter bags under pressured or non-pressured physical environments. Twenty samples of each material were used. The contents obtained under different environments were compared by linear regression. The NDF and ADF estimates were found different between physical environments for all materials (P<0.01). The utilization of pressured environment is recommended to avoid gas accumulation in the bags, which may compromise the detergent action.(AU)
