Effect of Adding Dry Leaves of Lemongrass (Cymbopogon citratus) To the Diet on Some Biochemical Tests of Blood in Broiler (Ross 308)

Abstract

Abstract The experiment aimed to improve the physiological characteristics of (ROSS 308) broiler chickens by using lemongrass as a natural antioxidant and vitamin E as a synthetic antioxidant, The experiment included four treatments in each treatment 36 chicks distributed over three replications randomly (12 chicks / replicate), the chicks were distributed to the treatments randomly in the experiment: the first treatment: T1: control and it was without any addition to the diet, the second treatment T2: the diet contained On 300 mg of vitamin E per kg of feed, as for the third and fourth treatment, powder of 5 g / kg of feed and 10 g / kg of feed of lemongrass were added, respectively. The experiment included studying Biochemical tests of blood. The results of the study showed that the addition of lemongrass was significantly superior (P≤0.05) in the blood plasma proteins of broiler chickens. It also improved the results of the lipidprofile test in broiler. The results also showed that the addition of different levels of lemongrass and vitamin E to the diet reduced the activity of liver enzymes. (AST, ALT) of broiler compared with the control treatment of the experiment.
