Abstract:

A biological experiment of 42 days duration was undertaken in day old chicks (n= 384) divided into 12 dietary treatments as per 3x4 factorial design having 4 replicates per treatment with 8 birds in each. Twelve experimental diets were prepared by incorporating control, two different levels of rice gluten meal (RGM) consisted of (15 and 17.5%), without and with three different types of enzymes xylanase, protease and multienzymes. The nutrient utilization in terms of nitrogen retention, apparent metabolizable energy of the diets, dry matter and gross energy metabolizability were significantly (P<0.01) lower at 17.5% level as compared to 0 and 15% RGM levels. The dry matter metabolizability and nitrogen retention of the birds were significantly (P<0.01) better in protease enzyme supplemented groups compared to control and other enzyme supplemented groups. The interaction of RGM and enzymes showed no significant (P>0.05) difference in nutrient utilization between different dietary treatments and control in gross energy metabolizability, calcium and phosphorous retention. The protein and energy efficiency ratios of birds were not influenced by RGM feeding, whereas significant (P<0.05) improvement were observed in protease supplemented birds. Thus, it may be concluded that protease enzyme supplementation was found best in RGM diet to improve their feeding value and it may be used to increase the effective and safe inclusion level from 15 to 17.5% in broiler diets.
