Description An experiment was conducted to study the effects of 5, 10, 15, and 20% of distillers dried grains with solubles (DDGS) with and without enzyme supplementation as a partial replacement for sources of protein and energy in corn-soybean meal based diet on broiler performance, skeletal integrity, serum parameters and carcass traits in commercial broiler chickens. DDGS is an ethanol industry based by product with medium energy and protein value. Four hundred, day old commercial broiler chicks were randomly allotted to 80 replicates with 5 chicks in each replicate. The birds were raised in battery brooders under uniform management and fed the respective diets from day one to 42 d of age. Iso-caloric and iso-nitrogenous diets were prepared by replacing corn-soybean meal basal diet for starter and finisher broiler chicks to meet the nutritional requirements, as recommended by NRC (1994). T1 was the corn-soybean meal control diet, T2 to T5 were DDGS in corn-soybean meal diet without enzyme supplementation at 5, 10, 15, and 20% level respectively and T6 to T8 were DDGS at 10, 15, and 20% in corn-soybean meal diet with 0.025% enzyme supplementation, respectively. Each diet was allotted to 10 replicates at random and fed ad libitum from 1 to 42 d of age. Body weights, feed intake and feed conversion ratio (FCR) were measured at weekly intervals. Blood was collected from one bird per replicate on 35th d for estimation of protein, calcium and phosphorus in serum. The hock joint scores of all birds were recorded at the end of the experiment for leg abnormality. At the end of the experiment, one bird from the each replicate was selected randomly and slaughtered to study the carcass traits and left tibia was excised for analysis of ash and bone strength in tibia.
Supplementation of various levels of DDGS without enzyme at 5, 10, 15, 20% and DDGS with enzyme at 10, 15, 20% significantly (P
