‘New generation’ Dried Distillers’ Grains with Solubles (DDGS) collected from modern ethanol plants were analysed for its nutritional composition and included in the diet to assess the performance of commercial Vanaraja chickens. Six numbers of commercial ‘new generation’ DDGS samples collected from modern ethanol plants were analyzed for their basic nutrient composition and amino acid profile. Five isocaloric and isonitrogenous experimental diets containing graded levels of ‘new generation’ DDGS (0, 2.5, 5.0, 7.5 and 10% DDGS) were formulated as per ICAR-DPR standards for Vanaraja chickens basis, and fed for chicks (9 replicate pens containing 6 chicks each) of commercial dual purpose birds of Vanaraja strain for the period of 6 weeks. Growth performance of birds was recorded at 7, 14, 21, 35 and 42 days of age and 9 representative birds per treatment (one each from replicate pen) were randomly selected and processed to study their carcass yield and characteristics. The ME and CP content of ‘new generation’ DDGS is 2850±57 Kcal/Kg and 27.35±1.16%, respectively. There was no significant (P>0.05) difference in the growth performance of birds during chick stage (7 to 21 days) and during early finishing stage (35 days) birds fed diets containing ≥5.0% ‘new generation’ DDGS had shown lower weight gain and significantly (P<0.05) poor feed conversion compared to Control. There was no significant difference in the carcass yield and its characteristics between the dietary treatments. Good quality protein rich ‘new generation’ DDGS can be used (10%) in the diets fed to commercial Vanaraja chickens without significant impact on overall performance of birds.
