ABSTRACT The utilization of Nigella sativa protein meal (NSM) was studied by replacing soybean meal protein (SBM) with NSM protein at 0%, 50% and 100%.This means that NSM was used instead of SBM in starter diets at 0, 24.7 and 50%, and in finisher diets at 0, 22 and 44%.Moreover, the different diets given to broiler chickens raised under high ambient temperature from 1 to 45 days of age were supplemented or 156 not by an enzyme cocktail (0.

5g/kg).A total of 210 broilers were divided into 6 treatments, each consisting of 7 replicates of 5 chicks each.The results of the interaction showed that complete replacement of SBM with NSM at 50 and 44% in the starter Bumper Guards and Accessories (1-30 d) and finisher (31-45 d) diets, respectively, did not negatively affect growth, feed intake, feed conversion ratio (FCR), carcass characteristics, inner organs, meat quality, and immune organs.However, the interaction between the level of NSM used and the supplementation with the enzyme cocktail supplementation had significant effect on white blood cells, revealing that enzyme effect is related to the diet composition.

Therefore, it could be concluded that Nigella sativa meal can replace all soybean meal and can be included at 50 and 44% in starter and finisher diets, respectively, without any negative effects on the performance and carcass yields of broilers raised under high ambient temperatures from 1 to 45 days of age.
