Abstract

Objective: This study was conducted to investigate the effects of green tea and rosemary extracts and their mixtures on growth performance, carcass characteristics, blood biochemical parameters, oxidative stability of meat and expression of interleukin-6 genes and interferon gamma in broiler chickens. Materials and methods: Birds fed on a Corn-Soybean. The study was conducted in a completely randomized design with a 3 × 3 factorial arrangement with 9 treatments and 4 replications, each replication containing 15 birds. (540 Ross 308 broiler chickens). The experimental diets included the control diet (without extracts) and the levels of 0. 5 and 1 g / kg extracts of green tea and rosemary. Results: The results showed that the use of mixture of rosemary extracts increased feed intake, increased weight and improved feed conversion ratio at the end of broiler chickens breeding (P<0. 05). Among the experimental groups, 0. 5 rosemaryextract (g/kg of feed) had the best production index (P<0. 05). The use of these extracts in the diet of broiler chickens has significant effect on liver enzyme (P<0. 05). These exteracts reduce the amount of malondialdehyide produced in the drumsticks of broiler chickens (P<0. 05). The different levels of these plant compounds increased the expression ofinterleukin-6 and gamma interferon liver genes. Conclusions: In general, it can be stated that the mixture containing 0. 5 rosemary extract (g/kg of feed) has the most effect on performance improvement, oxidative stability of meat and expression of liver genes in broiler chickens.
