Effect of Adding White Tea Leaves Powder (Camellia sinensis) to Broiler Chicken Diets on Some Biochemical Blood Parameters

Abstract

This study aimed to evaluate the effect of dietary supplementation of white tea leaves powder (Camellia sinensis) on some biochemical parameters of broiler chickens. A total number of 360 one-day old unsexed broiler chicks (Ross 308) with similar average initial body weight were used. Chicks were randomly divided into two main experimental groups (each of 180 chicks). The 1st main experimental group was provided with normal water (NW) while the 2nd main experimental group was exposing to the oxidative stress by providing normal water with 0.5% of H2O2, each main experimental group was divided into four treatments (each of 45 chicks), with three replicates (15 chicks /replicate), according to feeding diets supplemented with white tea powder were (T1): chicks fed basal diet without adding white tea powder, while the second (T2), third (T3) and fourth (T4) group were chicks fed basal diet supplemented with 1, 2 and 3g white tea leaves powder/kg diet, respectively. The results obtained showed that broiler chicks provided by the normal water has the better biochemical blood parameters than those received the oxidative water. Broiler chicks fed diets supplemented with different levels of white tea leaves powder improve some physiological and biochemical blood parameters than control group. From the results obtained in this study, it could be recommended with feeding broiler chicks (Ross 308) on diet supplemented with 3g/kg feed and provided with normal water seemed to be adequate to achieve the favorable results for improve the biochemical and physiological parameters.
