Exogenous enzymes in pre-starter broiler diets based on corn and soybean meal

a fibrolytic enzyme complex was added to the pre-starter diet. broiler chicks were randomly distributed into five treatments, consisting of a diet with no enzyme addition and four test diets supplemented with 100, 200, 300 and 400g/t of an enzyme complex. the dietary inclusion of the enzyme complex increased weight gain, and the dose of 300g/t improved weight gain and worsened feed conversion ratio.
