Abstract
Feeding enzymes to poulcry is one of the major nutritional advances in the last fifty years
(Kfiattak ef at., 2006). The use of enzymes in animal Feed is o£ great importance as using high levels of good vegetable protein sources such as Soybean meal poses certain problems like increased viscosity of gut contents, poor digestibility and poor chick due to its high fiber content (?.5 % CF). SBM is rich in non-starch (NSP) which reduces the digestibility of the SBM. Zanella e/ at. (\ 999) that these effects of NSP can be overcome of with suitable exogenous enzyme acids in a wide range of natural feed ingredients, allowing lower protein diets to be formulated without loss in animal performance.
Protease is a protein digesting enzyme that breaks down storage proteins binding starch within feed ingredients. This makes the energy From protein bound starch available to the bird to be used for productive purposes. Proteases are also effective in releasing protein anti-nutrients found in ingredients like soybean meal. This function of proteases makes proteins more available (Panda el at., 1 998]. Protease enzyme improve the digestibility of amino acids in a wide range of natural feed ingredients, allowing lower protein diets to be formulated without loss in animal performance. Not only does such use provide cost savings for the user.
