| Abstract | ||
| This study was conducted at the Poultry Farm of Animal Resources Dep. /College of Agriculture-University of Baghdad during the period from 20/12/2012 to 20/6/2013 to investigate the effect of chemical treatment Rice Bran (as a partial replacement) for Yellow Corn in laying hens diets on productive performance of laying hens. One hundred and twenty six hens of commercial strain (Lohmann Brown) 19 weeks old were used in this experiment. The hens were weighted individually and distributed in to eleven experiment treatments. Each treatment with three replicates and each replicate consisted of 6 hens. The birds fed the experimental diets which were as following:Treatment1 (Control group T0)100% yellow corn + 0.0% rice bran,Treatment 2(A1)75 % yellow corn + 25 % raw rice bran,Treatment 3(A2) 50 % yellow corn + 50% raw rice bran,Treatment 4 (B1)75% yellow corn + 25% Acid treated rice bran,Treatment 5 (B2) 50% yellow corn + 50 % Acid treated rice bran,Treatment 6 (C1) 75 % yellow corn + 25 % Alkali treated rice bran,Treatment 7 (C2) 50% yellow corn + 50% Alkali treated rice bran. The data of this study revealed that no significant differences between treatments (accept Alkali treatments) groups during production periods in the mean of egg production percentage (H.D.%) ,egg mass, feed intake, feed conversion ratio, live body weight, weight gain and mortality ratio. The Acid treatment group (B1) recorded the highest mean egg weight (64.24 gm) as compared with other treatments, it can concluded from this study that a partial replacement of raw or Acid treatment Rice Bran for Yellow Corn in laying hens diets has no adverse effect on productive performance of laying hens. | ||
