| Abstract This experiment was conducted in the poultry hall that belongs to the Department of Animal Resources, College of Agriculture and Forestry,Mosul University.This study were run out on 120 broiler chicks of Ross strain with age one day-old and the rate of primary weight were about equal 45 gm and its distributed these chicks randomly to four treatments with three replications for each treatment and then distributed these treatments were randomly assigned to four diets which is similar in the level of crude protein and metabolizable energy represented in two stages of fattening experiment (started and growth).These rations were added of sputter briber rates substitution 0,8, 16, and 24% instead of replacing of soybean meal in diets for the four consecutive at the stage started it by starting from the age of one day up to 28 days and the stage of growth starting from the age of 29 days up to 49 days of age.The results of statistical analysis for this study the existence of highly significant differences (P≤0.01) on the final live weight, total weight gains,total feed consumption, feed conversion efficiency and the proportion of mortality between four treatments.As about carcass traits the results of statistical analysis showed the existence of significant differences (P≤0.05) on dressing percentage,fat guts and highly significant differences (P≤0.01) on carcass weights, proportion of edible parts between four treatments respectively.As for spare carcass has indicated the results of statistical analysis observed the existence of significantly differences (P≤0.05) on both major and minor cuts percentages and highly significant differences (P≤0.01) on breast and rack percentage between four treatments. We can concluded from the results of this study that there were significant improvement in most of the qualities mentioned above and for the benefit was in third treatment (16%sputter briber) when compared with other treatments (0,8, 24% sputter bribe) | ||
