Effect of feeding rice gluten meal with and without enzymes on immunity of broiler chickens

A biological experiment was conducted to evaluate the effect of feeding rice gluten meal (RGM) as soybean replacement without or with different enzymes on immunity in broiler chickens for 42 days. The experiment was conducted as per 3x4 factorial completely randomized design. A total of 384 broiler chicks of same hatch with uniform weight were used. There were twelve different treatments with 4 replicates for each treatment and each replicate consisted of 8 chicks. Two levels of RGM were taken (15 and 17.5%). Protease, xylanase and multienzymes supplementation under different treatments were done. Effect of feeding different levels of RGM (0, 15 and 17.5%) without or with enzymes (xylanase, protease and multienzymes) and their interaction with enzymes did not exhibit any significant (P>0.05) difference between control and other dietary treatments on CMI and humoral immunity. Thus, it may be concluded that 15% and 17.5% RGM levels with or without enzyme supplementation had not any adverse effect on immune response in broiler chickens.
