Abstract:

This experiment was conducted for comparison, the effect of garlic powder, black cumin seeds powder and wild mint powder on performance and carcass characteristics of broiler chickens. Based a randomized completely design, 320 days old Ross 308 broilers were distributed into 16 floor pens and reared for 42 days. A basal diet was formulated according to NRC recommendations for starter (0-21 days) and grower (22-42 days) periods. The basal diet was also supplemented with garlic powder, black cumin seeds powder and wild mint powder, resulting 4 dietary treatments were prepared including control group. Each dietary treatment was fed ad-libitum to 4 replicates group of 20 birds at the bigining of rearing period. There were no significant differences in feed consumption at all of treatments in rearing period (p>0.05). The birds fed the diet containing black cumin seeds powder had the highest body weight gain as compared with other treatments (p<0.05). The best Feed Conversion Ratios (FCR) was recorded with birds fed diets contained black cumin seeds powder compared with control and other groups through all growing periods (p>0.05). The lowest (p<0.05) abdominal fat percent were recorded for broilers fed the diets supplemented with garlic powder and black cumin seeds powder (p<0.05). Also, the highest carcass percent were recorded for birds fed diets supplemented with black cumin seeds powder and garlic powder (p<0.05). The percent of breast in birds received black cumin seeds powder significantly was higher than wild mint and control groups (p<0.05). The percent of thigh was not affected with feed treatments (p>0.05).
