Abstract

This study was conducted at the poultry farm belong to Animal Resources department, College of Agriculture, University of AL- Anbar during the period of April 25 to June, 2013. The objective of this study was to study the effect of adding garlic powder and cupric sulphate and their effect on broiler performance. One-hundred and fifty one-day old unsexed Ross chicks were used with average weight 43 gm, the birds randomly distributed into five treatments with three replicate per treatment(10 chicks/treatment).The birds fed similar ration in crude protein and metatabolizable energy during starter and finisher periods. T1 (control) without any addition, T2 cupric sulphate was added at level 250 mg/kg feed, T3 cupric sulphate was added at level 350 mg/kg feed, T4 Garlic powder was added at the percentage of 0.75%, T5 included addition of garlic powder at percentage 1.5%.
The results revealed the following: The treatments included additions had significant improvement in live body weight and accumulative body weight gain as compared with T1 From 1-42day of age. A significant decrease in the accumulative feed consumed in treatments T2 and T5, The results show significant improve in feed conversion ratio of birds in all additives treatments as compared with T1 (control) and best value was to T5 (Adding garlic powder at 1.5%) which recorded 1.79 gm feed/gm weight gain and lowest value was to T1 which recorded 1.88 gm feed/gm weight gain. No significant differences in digestive organs of broilers. These results indicate adding garlic powder and cupric sulfate to rations had improved broiler’s performance
