The aim of the present work was to evaluate palatability, apparent digestibility, nitrogen balance and nutritive value of diets based on different level of Vicia faba minor comparing to soybean meal. Six Sarda breed wether were used in a two replicated 3 x 3 Latin Square design. Animals were fed in three periods with three experimental diets. Diets were formulated on the basis of natural meadow hay. Two diets contained different levels of Vicia faba: 20% (F20) and 38% (F38) as fed, with a crude protein content of 13,8% and 17% (on dry matter basis) respectively. The third, used as reference diet, was based on soybean meal (S) with a crude protein content of 15,8%. Apparent digestibility values and statistical differences for DM were: 70,0A% (F20), 74,2B % (F38) and 70,0A % (S), for crude protein: 73,3A % (F20), 78,0Bb % (F38) and 76,8Ba% (S). A positive nitrogen balance was observed with the following values: 7,7a g/d (F20), 9,0b g/d (F38) and 9,2b g/d (S). Nutritive value of diets was: 0,82A milkFU/kg (F20), 0,90B milkFU/kg (F38) and 0,84A milkFU/kg (S). Results showed that Vicia faba minor can be used to replace soybean meal in sheep.
