Mohamed Nabil Ali Ahmed. Improvement the utilization of some feed ingredients with high contents of fiber in poultry diets Unpublished Doctor of Philosophy Dissertation, University of Ain-Shams, Faculty of Agriculture, Department of Poultry Production, 2002. Four experiments were designed to study the improvement of high fiber diet by using some non feed additives, Sodium sulphate, enzyme preparation (BG or VG enzyme), radish extract (as a source of peroxidase enzyme) and enzyme preparation plus radish extract. Artificial dried Miskawi berseem (ADB) was used in two experiments (1 and 2) with levels of 10% in starter diet and 20% in finisher diet. The diet contained 21.20, 17.80% crude protein and 2778, 2658 k cal metabolizable energy/kg for starter and finisher broiler diets, respectively. Addition of radish extract increased body weight while addition of sodium sulphate improved feed conversion. Enzyme, sodium sulphate, radish extract and enzyme plus radish extract improved digestibility of nutrients. The use of ADB decreased fat content and increased protein content in meat. Also, wheat bran (WB) was used in other two experiments (3 and 4) with levels of 10% in starter diet (21.15% crude protein and 2778 kcal metabolizable energy) and 30% in finisher diet (17.91 % protein and 2481 kcal metabolizable energy) in the third experiment. In the fourth experiment, the same treatments were tested beside diets contained 30% WB in both starter and finisher diet. In general sodium sulphate, enzyme, radish extract and enzyme plus radish extract succeeded in improving performance and digestibility of all nutrients. The use of wheat bran decreased fat and increased protein content in meat. Sodium sulphate was found to be the excellent additive to improve the utilization of wheat bran.
