The experiment was conducted to evaluate the nutritional value and the partial substitution of crude protein (CP) of alfalfa hay (FA) with CP hay maniçoba (FM) in diets for growing rabbits. The performance, digestibility, carcass yield and prime cuts parameters submitted to experimental diets were studied. Treatments consisted of four levels (0, 25, 50 and 75%) of protein alfalfa hay and maniçoba hay. The increasing substitution levels of maniçoba hay resulted in a linear increase in feed intake and weight gain quadratically at 83 days, showing that this ingredient can be used as a substitute for alfalfa hay in the diet of rabbits. The protein of alfalfa hay can be partially replaced by the maniçoba protein hay.
