A composition for improving digestibility of leguminous foodstuffs by poultry is provided comprising cellulase, acid or alkaline protease, alpha-galactosidase and zylanase and/or amylase. Preferred compositions have proportions of enzymes therein of 20-40 % wt cellulase; 20-40 % acid or alkaline protease; 20-40 % alpha-galactosidase and 5 to 15 % zylanase and/or amylase. Feedstuffs are provided comprising the enzyme compositions together with seeds, preferably peas, beans, rapeseed and soyabean meal. Preferred feedstuffs have the activity of the enzymes in units of 1200 - 2000 CMCase per gramme and 2000 - 4000 CI ase per gramme of cellulase, 400 - 800 protease per gramme, 400 - 800 GA per gramme alpha galactosidase and 200 - 300 FA per gramme amylase. |
