Abstract

This experiment was conducted to investigate the effect of dietary supplementation with 1% black seed and/or garlic powder on some productive traits. The transactions were as follows: The first treatment (T1): Diet comparison, free of any additives. Second treatment (T2): the addition of 1% of the seeds of the Nigella sativa. Third treatment (T3): the addition of 1% of powder Alium sativa to dietary. Fourth treatment (T4): the addition of 1% of the Nigella sativa and 1% of powder Alium sativa to dietary. Atotal of 300 day old,nonsexed Ross broiler chicks, were allocated into four treatment groups with three replicates each one (25 chicks/replicate),during all the experimental period which is lasted at 42 day old. Results showed thet body weight,body weight gain and feed efficiency were significantly (P<0.05) increased in the birds supplemented with 1%(black seed + garlic powder) in comparison with other treatments.However,black seed,and garlic powder groups(1% of diet) surpasses control groups with relation to all traits included in this exeriment mortality percentage,and feed intake were not significantly differenced between the treatment groups.
