| Abstract | ||
| A total of 192 broiler chicks Ross 308 one day old unsexed were randomly into four experimental treatments (three replicate / treatment, 16 birds / replicate) .The chicks feed in two stages : starter 1-21day , grower 22-49 day , in both stages used four percentages from black seed meal : 0 , 20 , 40 and 60 % replacement soybean meal in diets . The results of study showed significantly differences (P≤0.05) for all treatments compared with T4 in total body weight,total weight gain,average growth rate,and for control group in total feed consumption,while in feed convertion ratio,pancreas,abdominal fat percentage for T4,allso T3 get a significantly effect (P≤0.05) in production index,economic figure,dressing percentage,main cut,breasts,thighs and heart,but the treatments had no effect in secondary cut,back,neck,edible bewols,liver and gizzard. The economic efficincey,T3 get the best revenue and net revenue percentage . | ||
