UPAYA PENURUNAN TINGKAT CEMARAN DAN TOKSISITAS AFLATOKSIN B1 PADA JAGUNG SERTA PENGGUNAANNYA SEBAGAI PAKAN BROILER

The aim of this research was to reduced of contaminant and toxicity aflatoxin B1 (AFB1) in corn as broiler feed by controlling the moisture content of corn at the beginning of the storage and decreasing the toxicity by giving methionine in the broiler feed. The research was conducted at the Poultry Laboratory , Clinical Pathology Laboratory, and the Laboratory of Research and Integrated Development (LPPT), Universitas Gadjah Mada. The research consisted of three stages, starting from August 2007 to November 2009. The first stage of research: the influence of the moisture content of corn before storage on AFB1 contaminants, and the development of fungi during storage. In this research, a preliminary survey concerning the level of contaminat in corn was conducted in some areas in Indonesia : Blitar, Klaten, Gunungkidul and Tasikmalaya. The research result AFBI ranged from 0.91 to 45.41 ppb at the farmer level and 29.00 to 243.03 ppb at the traditional market. The data showed that although the corn was already kept for 6 months, the corn with 13% and 15% moisture content, could still be used as good substance of feed. The second stage of the research aimed at reducing AFBI toxicity in broiler with methionine. The research used raw AFB1, produced by planting isolat FNCC 6122 Aspergillus flavus. There were three replications for each feed treatment. DOC male broilers were being fed with 3 levels of methionine (0.
