Effects of wheat screening wastes treatment with enzyme and probiotic on performance, carcass traits, nutrient digestibility and intestinal morphology in broiler chickens

This experiment was performed to evaluation treated wheat screening waste in diet of broiler chickens. A total of 432 broilers (Ross 308) were used in completely randomized design for 9 treatments with 4 replicates of 12 chicks per replicate for 42 days. Treatments included 1) corn and soybean meal 2) corn and soybean meal in which 15% corn was replaced with wheat screening 3) corn and soybean meal in which 30% corn with substituted by wheat screening 4) diet 2 Natuzyme plus500 g /tone of diet 5) diet 3 + Natuzyme plus diet 500 g / tone of diet 6) diet 2 + protxin 150 g / ton of diet 7) diet 3 + protxin 150 g / tone of diet 8 ) diet 2+ 75 g protxin + 250g Natuzyme plus /ton of diet 9) diet 3+ 75 g protxin + 250g Natuzyme plus /ton of diet. In terms of production efficiency index, the highest levels was observed in control and in the diet containing 15% wheat screening with and without enzyme, probiotic and enzyme + probiotic (P<0.05). The highest villi length was observed in the treatments receiving 15% wheat screening wastes + multi-enzyme + probiotic supplement )P<0.05). In conclusion, the results of this experiment showed that, corn of diet replaced by 15% of wheat screening pluse 250 g of enzyme + 75 g probiotic per ton of diet can be used in broiler diets without any adverse effects on performance, production index and nutrient digestibility
