This research was conducted to evaluate the effect of the spices (Capsicum annum, Allium sativum and Thymus vulgar is) used as feed diet for broiler. A total of five hundred broiler chicks (Cobb 500) aged one day, not sexed were distributed from the third week in four experimental groups. The chickens were fed with four diets. The first group (A) is fed with a diet without feed additives (control diet). The other groups (B), (C) and (D) were fed respectively with growth basal diets supplemented with respectively 1 g / kg of Thymus vulgar is, 1g / kg of Allium sativum and 1 g / kg of Capsicum annuum. The chickens were fed with these different diets during the four week of growth period. The feed consumption, the weight gain, the feed conversion and the mortality were recorded. Also the chickens’ meats from the different batches underwent a sensory analysis. At the end of the experiment, the results showed that the diet supplemented with Capsicum annuum was significantly (P <0.05) the higher of body weight gain (1.68 ± 1738g), the best of consumption index (1.46 ± 0.03), the high feed consumption (2.42 ± 0.03) and the best firmness of the meat. No significant difference at the level of the mortality rates was observed between the supplemented feed. But a significant difference (P <0.05) was obtained between the control diet and supplemented rations. The Capsicum annuum is one of spices contributing to improve the growth of broilers.
