Abstract

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<0.05). The highest percentage of ileal digestibility of crude protein, crude fat, phosphorus and apparent metabolisable energy were seen in broilers fed by 1, 3 and 5 diets (P<0.05). In conclusion, replacing of corn and soybean meal in based diets up to 50% with grade one of wheat screening waste and canola meal pulse multi enzyme had no adverse effects on performance, production index and ileal nutrient digestibility. Consuming of this diet, from economical aspects had suitable.
