Evaluation the effects of using multi enzyme in diets containing different levels of canola meal and wheat screening wastes on broiler chickens performance, carcass traits and ileal digestibility of nutrients

For study the effects of different levels of wheat screening waste, canola meal with and without multi enzyme on performance, viscosity and nutrient digestibility, 240 Ross- 308 male broiler chicks were used in a completely randomized design with six treatments and four replicates by 10 chicks in each replicate from 11 to 46 days. Diets were: 1) Diet based on corn-soybean meal (control), 2) Basal diet replaced by 50% wheat screening waste and canola meal, 3) Basal diet replaced by 100% wheat screening waste and canola meal, 4) Diet based on corn-soybean meal pulse 500 g multi enzyme/ton of diet, 5) Basal diet replaced by 50% wheat screening waste and canola meal pulse 500g multi enzyme/ton of diet, and 6) Basal diet replaced by 100% wheat screening waste and canola meal pulse 500g multi enzyme/ton of diet. The best feed conversion ratio, energy and protein intake efficiency, production efficiency index achieved in 1, 4 and 5 diets (P
