Globally, poultry products have been considered as an indispensable source of animal protein and it is speculated that the demand of animal protein will be increased by 60-70% in 2050 for human consumption and much of this share will come from developing nations. This research was executed to find out the nutritional influence of corn steep liquor and enzose mixture as a non-conventional protein ingredient in day old broiler chicks. For this purpose, 42 days study was conducted using hubbard broiler chicks (n=200). The birds were divided into 5 groups containing 4 replicates having 10 chicks each. Birds were offered 5 iso-caloric and isonitrogenous broiler starter (metabolizable energy 2850 kcal/ kg; crude protein 20%) diet from day 1-21 and broiler finisher (metabolizable energy 2880 kcal/ kg; Crude protein 18%) diet from day 22-42 comprising 0, 3, 6, 9 and 12% CSL and Enzose mixture (50:50 ratio). It was that broiler fed diet B gained higher body weight (p<0.05) and exhibited lower feed conversion ratio as compared to other treatments. Birds fed diets B (CE3) also exhibited significantly higher nutrient digestibility and carcass characteristic as compared to other treatments. Growth responses, nutrient digestibility and carcass characteristics of birds were optimized fed 3% of CSL and Enzose mixture as compared to others.
