The aim of this research were to assess nutritionally the in natura sugarcane bagasse enriched or not with vinasse in diets for growing rabbits and for this purpose were conducted three experiments. In the first experiment (cap. II) was held the nutritional evaluation of diets containing in natura sugarcane bagasse not enriched (BC) and in natura sugarcane bagasse enriched with vinasse (BCV) in relation to a reference (REF) diet for growing rabbits, and its influence on apparent digestibility of nutrients. We used 30 New Zealand White rabbits of both sexes. The experimental design was completely randomized with three treatments and ten replications. This test determined the digestibility coefficients of nutritive principles and the values of ED and PD of diets and testing feeds. In the second experiment (cap. III) was evaluated the nutritional contribution of cecotrophes of growing rabbits fed with diets containing in natura sugarcane bagasse not enriched (BC) and in natura sugarcane bagasse enriched with vinasse (BCV) in relation to a reference diet (REF). Ten animals per treatment were used with 66 days of age, for which it was assessed the pattern of caecotrophy curves, the nutritional value and nutrient contribution of cecotrophes. In the last experiment (cap. IV), assessed the productive performance of growing New Zealand White rabbits fed diets containing in natura sugarcane bagasse enriched with vinasse, included from results obtained in chapter II. Four diets were studied in a completely randomized design with four treatments and 22 repetitions with a rabbit by repetition, housed individually to 30 days of age (weaning) and finished at 65, when they hit an average live weight of 2 kg, the treatments consisted in inclusion 0; 5; 10 and 15% of bagasse in natura sugar enriched with vinasse.
