12 porkers, 70 kg body weight, divided into 3 groups were fed as follows: diet control (1) 2.6 kg CCM silage + 0.85 kg Prowit concentrate, diet (2) 2.2 kg CCM silage + 0.45 kg Prowit + 0.75 kg ground faba beans (FB), diet (3) 2.9 kg CCM + 25% FB silage + 0.45 kg Prowit. Feed chemical composition including aminoacids, nutrient digestibility and nitrogen balance in porkers were determined. Drop of trypsin inhibitor activity was observed in ensiled FB. Biological value of protein in CCM + FB silage was higher than in CCM only. Using FB in diets, either raw or ensiled with CCM, did not affect crude protein and N-free extract, while reduced fat and crude fiber digestibilities. Nitrogen retention in group given diet (3) was reduced by 3 g/day.
