Abstract

In this study, the effects of four different doses of green tea (0.0, 0.250, 0.50, and 0.750 g/kg) on the nutritional status, blood profiles, and antioxidant status of broiler chickens were investigated. A total of four equal groups, each with four duplicates, and ninety sex-day-old, unsexed broiler chicks were reared in battery cages. Feed and water were offered ad libitum till the termination of the trial at 6 weeks of age. Throughout the whole trial period, the treatment supplemented with 0.750 g/kg of dietary green tea had the highest LBW. In contrast to the other groups, feeding the diet containing 0.500 g/kg of green tea increased FI during the whole study period. Over the course of the entire experiment, broilers fed a food supplemented with 0.500 g/kg green tea demonstrated considerably higher FCR than other experimental groups. Green tea-fortified diets did not significantly affect any group's bilirubin or HDL levels. However, dietary supplementation with green tea for broiler chicks resulted in significantly higher plasma levels of lipid profile and activity on transaminases compared to the control group. The positive impact of green tea addition in diets on the growth performance and blood parameters of broiler chickens was indicated by study findings.
