Protein debradability and transformation of miimosine from leucaena Leucocephala (LAM) de with in the rumen of buffaloes under diets with different protein levels

Abstract

The ruminal suspended nylon bags technique was used to study the degradability of crude protein and disintegration of minosin of Leucaena leucocephala in water buffaloes. The experimental desing was in a 4 x 4 Latin square, with variable levels of crude protein (8.8, 10,5, 12,5, and 14.9% of dry matter). The diets did not cause significant differences on the ruminal degradation of crude protein of Leucaena (P > 0.01), that ranged from 30.92 to 71.70% in, respectively, 3 or 48 hours of ruminal exposition. There was observed a clow ruminal protein degradation and a strong desingration of mimosin on the samples of Leucaena exposed in nylon bags to the rumen of water buffaloes
