Abstract

This study was carried out to investigate the effects of Natuzyme Plus (a multi enzyme) in diets containing wheat and canola meal on broiler performance. A total of 336 day-old Arbor Acres broiler chicks were used in a completely randomized design with six treatments and four replicates. Experimental diets were: 1 . Diet based on corn-soybean meal (control), 2 . Diet containing 30 precent wheat and 3 . Diet containing 30 percent wheat + 10 percent canola meal, which Natozyme was added (350 g/ton) to these diets to make diets containing enzyme (totally six treatments). Adding enzyme to diet containing wheat and canola meal increased significantly feed intake, weight gain and feed conversion ratio (FCR) at starter and overall rearing period (P< 0.01). Use of Natuzyme Plus in diet containing wheat and canola meal reduced significantly the relative weight of digestive organs in compared of same diets without enzyme. The results of this study indicate that the performance of broiler chickens fed the diets containing wheat and canola meal could be improve by supplementing with Natuzyme plus preparations.
