EVALUATION OF PARTIAL AND COMPLETE REPLACEMENT OF SOYBEAN MEAL BY FERMENTEED BROAD BEAN IN THE DIET OX THE PRODI ICTIVR PERFORMANCE OF BROILERS

Abstract

This experiment was conducted at the poulin farm of the Animal Resources Dept. . College of Agriculture. Universi;;. of Baghdad, for the period from May 23. 2004 to Jul) 2.1,2004 . to study the effect of partially or completely substitution cf soybean meal (S.B.M.) by fermented broad beans (Vicia /aba I.. Major) on productive performance of broilers . at 15-56 ci s of age. A number of 360 day old Luhman broilers ehieks were used in this study. The chicks reared as one group during ".he first two weeks of age. and then they were distributed randomly into 6 treatment groups (3 replicates / treatment), the treatment groups were as follows : Control group= 100% S.B.M. + 0.0% fermented broad beans. Tj = 80% S.B.M. + Z/'o fermented broad beans. T: = 60% S.B..M.+ 40% fermented broad beans. T3 = 40% S.B.M. + 60% fermented broad beans. 7- = 20% S.B.M. + 80% fermented broad beans and T5 = 0.0% S.B.M. + 100% fermented broad beans. The results of the sv..d) indicated that: no significant differences between control group and other treatment groups in live body weight. bod w.e:g~.". gain, feed consumption, feed conversion efficiency, and mortality rate. However highly significant differences (p<0.01 :r. carcass weight. Whereas dressing percentage (with or without giblets) and percentage of main carcass cuts at 8 weeks of age have not been affected significantly by the replacement of soybean meal by the fcrrncn.cd broad bean in the diets. Significar.: differences in the percentage of abdominal fat to live body weight have been noticed between Ti . T* and control group Results of this experiment refer to the possibility of substitution of soybean meal by the fermented broad beans in brcl.'er diets.
