Growth Performance, Carcass Characteristics and Fatty Acids Profile of Broilers Supplemented with Lauric Acid and Natural Antioxidant from Areca vestiaria Giseke

摘要

Background: Besides as an energy source, coconut oil with its la uric acid content can improve the growth performance, carcass characteristics and fatty acid s profile of broiler chickens. Conventional processing of coconut oil is susceptible to hydrolytic oxidation that reduces its antioxidant content. Areca vestiaria Giseke (AV) with its phenol content acts as a natural antioxidant in the diet. Materials and Methods: Two hundred and forty day-old unsexed Lohmann broiler chicks (MB-202 P) were divided into 24 experimental units (ten chicks/unit) and arranged in a completely randomized design with a 2×4 factorial arrangement. Each experimental unit was repeated 3 times each with ten chicks. The first factor was the source of la uric acid in the ration consisted of 2 levels i.e., coconut oil and pure la uric acid . The second factor was dose of antioxidant consisted of 4 levels i.e., 0 [without antioxidant (AV and la uric acid ) supplementation], AV at a dose of 625 mg kg^?1 ration, AV at a dose of 1250 mg kg^?1 ration and tocopherol at a dose of 200 ppm). Parameters measured were growth performance, carcass characteristics and fatty acid profiles of broiler breast meat. Results: On the first stage trial, AV can be used as a source of natural antioxidant in the diet of broiler. The feeding trial showed that the treatments highly significantly affected (pConclusion: AV as a source of natural antioxidant can be used as a supplement in broiler ration containing coconut oil as a source of la uric acid .
