Abstract
Abstract This study was conducted in the field of poultry - College of Agriculture - University of Muthanna to study The effect of replacing laboratories chemically rice husks by maize in diet on some production performance of broiler. Three hundred broiler chicks (Ross 308), one day old. The birds were distributed to four treatment groups with three replicates per treatment (75 birds per treatment), The treatment groups as follow: 1 -first group:- control. 2 - Second group:- Use laboratories chemically rice husks by 5% in the diet. 3 - Third treatment: - Use laboratories chemically rice husks by 7% in the diet. 4 - the fourth treatment:- used laboratories chemically rice husks by 10% in the diet As for the dressing percentage with and without edible viscera and the relative weight of the heart, liver and gizzard the T3 give a significant (P ≤ 0.05) increase compare the rest of treatments, the averages stood at 65.24, 69.63 , 0.325, 1.88 and 2.18 of the traits respectively, as well as higher than the average in the same treatment, the relative weight of main cuts (breast, thigh and drumstick), reaching averages 27.59 , 16.03 and 12.69 of the traits respectively, as for the average weights for secondary cuts (neck, wings and back) the results show superiority of treatment T4 (10% rice husks) on the rest of the experiment treatments, as the percentage averages 27.86 and 12.25 and 5.37 part of the back and neck and wings respectively, and it outperformed the treatment T3 in length and the relative weight of all parts of the small intestine and cecum (duodenal, jejunum and ileum) compared to the control and treatment of (T2 and T4).
