Aiming to evaluate the digestive use and performance of growing rabbits fed with diets con- taining sugarcane bagasse enriched with vinasse, 118 New Zealand white rabbits was used in a digestibility, caecotrophy and performance trials. The experimental design was completely randomized, being applied in the digestibility and caecotrophy three treatments (a reference diet, a diet containing sugarcane bagasse and a diet containing sugarcane bagasse enriched with vinasse) and in performance trial, four treatments (0, 50, 100 and 150 g kg - 1 of bagasse enriched with vinasse). The data were subjected to variance analysis and subsequently carried out comparisons between the averages of the treatments. The bagasse enriched or not with vinasse changes consumption, excretion and the digestibility coefficients of dry matter, mineral matter, organic matter, crude protein, ether extract and gross energy. The inclusion of vinasse promotes the improvement of the values of digestible energy and digestible protein of bagasse. There was no change in the dry matter of the ceco- trophes, while there wasn’t on the crude protein of cecotrophes by the inclusion of the bagasse enriched or not with vinasse. There was a reduction of the nutritional contribution in dry matter, from the inclusion of test feeds. This did not affect nutritional contribution in crude protein. The use of bagasse enriched with vinasse in diets for growing rabbits proved viable, so that the inclusion did not alter the average daily weight gain of ani- mals and therefore, the time required to reach slaughter weight.
