Abstract

Fermentation in the rumen is crucial in the supply of dietary nutrients of ruminant animals. The nylon bag technique has been extensively for measuring ruminal degradation of feed stuffs; therefore, it is essential to study the dynamics of rumen degradation of various feeds before their potential use to formulate nutritious diets for ruminant animals. Four models were fitted to the dry matter (DM) disappearance curves of 3 cuts of Alfa Alfa: Non lagged simple Mitscherlich or exponential (Model I); lagged simple Mitscherlich or exponential (Model II); Gompertz (Model III) and generalized Mitscherlich (Model IV). Results of DM degradability characteristics showed that models IV, III and II were the best fit to 1st, 2nd and 3th cuts, respectively
