| This experiment was carried out in the field of poultry of the Department of Animal Resources, Faculty of Agriculture /University of Tikrit, during 6/10/2011 to 11/24/2011. The aim was to determine the impact of growth and development and the optimal age for the slaughter of three hybrids of different broilers included 308Ross, Ross (importer) and Hubbard with the feasibility study. The birds have been slaughtered at the age of 32, 37, 42 and 47 days. 480 day-old chicks and one distributed randomly into three treatments each of which contained replicates and each of them contain 40 chick were select 12 birds from each treatment were randomly assigned to the purpose of slaughter, The results showed the following: a significant increase (p<0.05) with age among strains Ross308 and hybrid Ross (importer) and the hybrid Hubbard for each of the carcass weight and dressing percentage and percentage yields President and ratios yields secondary, increase the proportion of deboning (p<0.05) as a result of aging, as well as increasing the weight of meat, physically separated the hybrid Ross 308 and Ross (imported) and finally the hybrid Hubbard. | ||
