The effect of partial and complete replacement of raw and germination sorghum for yellow corn in broiler rations in some productive and physiological traits

Abstract

The present study was carried out at poultry farm belong to Animal Resource Department, College of Agriculture, University of Baghdad, during the period from 21/9/2012 to 26/10/2012 to investigate the effect of partial and complete replacement of raw and germination sorghum for yellow corn in broiler rations in some productive and physiological traits. Two hundred and townie fife (225) of broiler chicks Ross 308 were used in this study. This study was divided in to fife experimental groups and each group included 45 chicks. One group (T1) was control, chicks were fed on basal diet without any supplemented from sorghum. Second group (T2) 50% yellow corn + 50% raw sorghum, third group (T3) 0% yellow corn +100 % raw sorghum , fourth group (T4) 50% yellow corn +50% germination sorghum and fifth group (T5) ) 0% yellow corn +100% germination sorghum. Results showed as in following: Significant increase (p≤0.05) in life body weight and body weight gain for treatment 5 compared with treatment 3. Significant increase (p≤0.05) in feed intake for treatment 2 and 3. Treatments 4 and 5 was record best results in cumulative feed conversion compared with treatment 2 and 3, and no significant showed between treatment 4 and 5 compared with treatment 1. Treatment 3 revealedHigh significant decrease in dressing percentage compared with other treatment. No significant difference between treatments in physiological traits.
