the digestibility of nutrients was determined by the classical balance method the quantity of nutrients from the feed was decreased by the amount excreted in feces and this gave the amount of digested components the ratio of digested constituents to those intake expressed in percent indicated the level of apparent digestibility coefficients the ame values were calculated by subtracting the ge gross energy intake from the ge excreta and then dividing these values by the ge intake ame n was calculated by the following equation where fecal urinary energy n fecal urinary energy 34 36 n intake u2212 fecal urinary n and where 34 36 kj kg is the mean gross energy of the nitrogenous execratory products in the bird treatment effects were compared using the analysis of variance and treatment means were separated using the least significant difference the computation was done using the sas u00ae program version 9 1 statistical analysis system institute cary n c all tested formulations including the blank that served as a negative control were incorporated in a premix that was dosed at 5 kg per ton of feed the premix included enzymes a mycotoxin binder and carrier material premix base all tested products were incorporated in the premix at a dosage of 500 g the composition and code of the formulations is shown in.
