In developing countries, animal production is affected by the dependence on conventional ingredients or by its high cost, for which it is important to research agro-industrial by-products. Therefore, the purpose to this study was to evaluate the digestibility of diets for rabbits with sweet potato vines, in substitution to alfalfa hay. A biological essay was conducted to determine sweet potato vines digestibility, which took 12 days (5 for adaptation and 7 for collecting feces). A total of 27 rabbits received three different diets: reference (0SPV) and the ones with substitution of 10% (10SPV) and 15% (15SPV) of alfalfa hay for sweet potato vines. The coefficients of digestibility of dry matter were 51.47% (0SPV), 52.07% (10SPV) and 57.41% (15SPV); coefficients of digestibility of mineral matter, 15.17% (0SPV), 17.06% (10SPV) and 16.47% (15SPV); coefficients of digestibility of crude protein, 87.51% (0SPV), 84% (10SPV) and 83.79% (15SPV); coefficients of digestibility of neutral detergent fiber, 20.25% (0SPV), 19.65% (10SPV) and 24.48% (15SPV); coefficients of digestibility of acid detergent fiber, 16.06% (0SPV), 16.82% (10SPV) and 22.36% (15SPV). The conclusion is that sweet potato vines can replace at least 15% of alfalfa hay in growing meat rabbits diets.
