Abstract
An experiment was conducted at poultry research station of karbala Agricultural foundation during the period of 03/04/2014-22/05/2014 to identify the effect of adding black seeds (Nigella sativa) and thyme (Vulgaris vulgaris) on the microbial content and some of carcass features , for two different hybrids (Ross and Cobb) of broiler chicks. This experiment was carried out, using completely randomized design and as a factorial experiment, on 120 broiler chicks of each of the un-sexed hybrids mentioned above,distributed to 24 cages (1×1.5 m2/ cag).Six nutrition treatments each containing two replicates (10) were used. For each hybrid, black seed and thyme powders were added individually or mixed with the main diet to obtain the final ratio of 10 g./ kg. Results showed that no significant differences were found between the nutrition treatments and the studied features as well as the interaction between the boiler chick species and the nutrition treatments
