Abstract

Background And Objective: An abundantstud showthat leucine (Leu) acts as an anabolic agent that stimulates skeletal musce growth in human as well as in animals. Haver, the effect of encapsulated leucine (CL) supplementation on growth performance of broiler chickens has not been evaluated. Therefore, the aim of this study was to determine intlal metags responses to CL supplementation on food intake plan metabolites and branched chain amino acid concentration in 7-day-old broiler chicks. Materials and Methods: A total of 24 chicks were randomly assigned to the following treatments (1) Control 4 ) (2) Free leucine 4h iDand (3) Encapsulated leucine th (CL). After 6 Fasting, chicks were given a bolus of oral injection of distilled water, freel ne (6 mmol/10 ml.kg - BWor encapsulated-leucine (6 mmol/10 mt kg BW). Immediately after the injection, chicks were allowed free access to a commercialstarter diet for lh Blood collections were obtained after the oral injection Food intake total glucose total cholesterol, triacylglycerol, plasma leucine levels and the activity of glutamic oxaloacetic transaminase(GOT) were marred. Results: Food intake, glucose total cholesterol and triacylglycerol levels were not affected by Supplementation At 4 h, GOT levels were gre p .05)in the group than that were similar in all groups. Valine levels were lower (p<0.005) inthend Cl Groups of the groups At 4 h, although plasma leu os than that of thel.eu group and isoleucine levels were lower (p<0.001) in the group than that of the candle groups. Conclusion: The results of this study suggest that an oral administration of a caused prolonged leucine induced anabolics that may be beneficial for growth Our observations above the way for studying the long temeffects of supplementation performance of broiler chicks.
