The effects of liquid vinasse (LV) in the diet for growing rabbits on performance, carcass yield and intestinal morphometry were assessed. Eighty New Zealand white rabbits were used in a randomized block design with five treatments (LV inclusion at 0, 25, 50, 75 and 100 g/kg diet) and four replications. There was no effect of the treatment on final weight, daily weight gain, mortality rate and carcass yield characteristics. The daily intakes of feed, dry matter, crude protein and energy and feed conversion decreased linearly with increase in LV in the diet. Including LV affected the duodenum crypt depth and the ilium villus perimeter and height linearly and affected the duodenum villus perimeter, height and the absorption surfaces and ilium crypt depth and absorption surface quadratically. There was no effect of including LV on jejunum morphometry. Vinasse can be used to feed growing rabbits at up to 87.8 g per kilogram of diet.
