abstract
The experiment was conducted on 420 straight run commercial day old broiler chicks from 0-42 days. The chicks were randomly distributed into seven dietary treatments groups with three replicates of 20 birds each. The birds in control group A were offered basal diet adequate in all nutrients as per BIS, 2007. The birds in dietary treatment groups B, C and D were offered diet containing sorghum distillers dried grains with solubles (sDDGS) at 5, 10 and 15% levels and birds in groups E, F and G were offered diet having sDDGS at 5, 10, and 15% levels with multi-enzyme Ronozyme Max Act (GT) @ 400g/ton of feed, respectively. The antibody titers against ND (log₂ values) and ELISA antibody titers against IBD revealed non-significant differences in all treatment groups at 3^rd and 6^th weeks. There was a non-significant difference for dry matter intake, dry matter excreted, nitrogen intake, nitrogen excreted and DMM in all treatment groups. The nitrogen retention was significantly (P<0.05) reduced in treatment groups D (15% sDDGS) as compared to control group. However, the inclusion of sDDGS at 15% level with enzyme supplementation improved nitrogen retention in broilers and statistically non-significant as compared to control group. Thus, it is concluded that the inclusion of sorghum distiller’s dried grains with soluble up to 10% without multi-enzyme and 15% level with supplementation of multi-enzyme in broiler diets was found to be beneficial in terms of immune response and nutrient utilization in broiler chicken.
