Abstract: An experiment was conducted to evaluate the effect of dietary inclusion of fermented rapeseed meal (FRSM) with or without enzyme supplementation on the growth performance of broilers. A total of 240 day-old Cobb broiler chicks were randomly assigned to eight dietary treatments with three replicates of ten birds each for six weeks period. All diets were formulated to be iso-caloric and iso-nitrogenous, as per BIS (2007) standards. The control group (T1) received a corn-soybean meal based basal diet without FRSM or enzymes, while T2 was fed the basal diet with 0.02% enzyme supplementation. The treatment groups T3, T5 and T7 were supplemented with FRSM at 2.5, 5.0 and 7.5%, respectively, without enzymes, whereas T4, T6 and T8 received 2.5, 5.0 and 7.5% of FRSM with 0.02% enzymes, respectively. The results revealed no significant differences (p>0.05) among treatment groups with respect to body weight, feed intake, feed conversion ratio and survivability. It was concluded that dietary inclusion of FRSM up to 7.5%, with or without enzyme supplementation, had no detrimental effect on growth performance in broilers, indicating its safe incorporation in poultry diets.
