| Abstract | ||
| This study was conducted in the General Directorate of Agricultural Research-Ministry of Agriculture in Baghdad during the period from 10-10-2010 until 21-11-2010. The objective of this study was to compare the addition of garlic meal,black seed meal and the antibiotic Avilamycin as growth promoter in broiler diets and their impact on carcass characteristics. Two hundred and eighty one-day old (Ross 308( broiler chicks were used. The birds were unsexed and randomly distributed in to seven treatments with two replicates/ treatment (20 birds per replicate). The first treatment as the control without addition, the second and third included 0.7 and 1% of garlic powder, respectively, the fourth and fifth included 0.7 and 1% of black seed powder, respectively, the sixth and seventh included 0.005 and 0.01% of the antibiotic (Avilamycin), respectively. The chicks were raised in pens with (2×3 m) in a closed house. The results revealed that a highly significant (P≤0.01) improvement in the percentages of carcass cuts was shown in birds of treatments 2, 3, 4 and 7; whereas a highly significant decrease was shown in birds of T6; and there were no differences shown between T5 and T1. A highly significant improvement was shown in the percentage weight of breast cut in T3 compared with that of T1. The percentage weight of thigh cut in all treatments was significantly higher than that in T1.Its concluded that the dressing percentage and the relative percentages of the main carcass cuts were significantly improved when 1% of garlic and 0.7% of black seed powder were used in broiler rations instead of avilamycin. | ||
