The objective was to compare alternative models for fitting to data on degradation of dry matter (DM), organic matter (OM) and crude protein (CP) in the rumen of two harvests of four temperate grasses, made into hay in Belgium, and one harvest of three tropical grasses commonly used in Burundi. Fifteen non-linear models were used and these included generalized Mitscherlich, simple Mitscherlich (or exponential), generalized Michaelis-Menten, Gompertz, logistic, simple Michaelis-Menten, segmented Van Milgen and von Bertalanfly models. Degradation profiles of DM, OM and CP obtained in sacco from the rumen of three mature sheep were fitted to all the models. The convergence success rate along with acceptable parameters was used as a first tool ...
