    Abstract

    This study is the final part of a research program to find a model of protection of unsaturated fatty acid oxidation in broiler chickens by using natural antioxidants. Broiler meat contains high unsaturated fatty acids, thus susceptible to oxidation. Problems in human health from consuming fat is influenced by three things: quantity, type and condition of the fat. Free radicals are always formed during life, highly reactive oxidizing compounds are nearby, especially unsaturated fatty acids. Products of fat oxidation can lead to the emergence of degenerative disease and coronary heart disease. This condition can be prevented using antioxidants into their diet The purpose of this research is to study the comparative of antioxidant activity between of the three kinds of extracts on lipid oxidation through the dietary of broiler. In this case we observed a) comparative antioxidant capacity of three kinds of extracts on radical scavenging DPPH test b) how far the ability of the three kinds of extracts to delaying lipid oxidation in broiler c) how many levels that can be savely added to the ration in order to give good effect on performance and efficiency of production broiler chicken. This research was initiated to test the antioxidant activity of green tea extract (Camellia sinensis var. Sinensis), mangosteen peel extract (Garnicia mangostana) and peel of rambutan (Nephelium lappaceum) against DPPH free radical scavenging which was tested in vitro. Extracts were prepared by maceration method using 70% ethanol solvent. Results showed the extract yield of 25.83%, 21.62% and 26.72% respectively for green tea (ETH), mangosteen skin (EKM) and rambutan skin (EKR) with total polyphenol content of each 29, 60; 22.78 20.68% EAG and IC50 values of 5.76, 8.69 and 11.32 ug / mL. of each. Further on in vivo tests using 120 DOC broiler strain Lohmann, supplementing the three kinds of extracts at 0.2% / kg diet that given for 35 days did not significantly affect on performance of chickens, but can significantly inhibit lipid peroxidation in breast meat and liver with no influence on pH and WHC. The conclusion of this research is three kinds of extracts have equel of antioxidant capacity and considered very powerful antioxidants that can be used as a natural antioxidant in broiler chickens at a dose of 0.2% extract / kg diet.
