Abstract


The research was conducted to evaluate the storage effect of formulated feed containing fermented onggok (FO). The analysis were performed on physico-chemical and microbiological properties. The fermented onggok (FO) was added level with the composition variation of 15, 20, 25 and 30%. Variables measured were texture, colour, odour, dry matter, crude protein, total microbes and Aspergillus flavus colonies. All of FO feed were stored for 5 months. The results showed that feed with 20% OF had un-agglutinated texture, brown colour and good odour which indicated the particular feed had good stability during storage. The highest Crude protein (CP) was found in the sample containing 20% FO, while the sample with showed 30% the highest total of microbes and A. flavus with the value of 2.5 x 10 3 and 6.5 x 10 2 cfu/g respectively. It was concluded that feed contained 20% FO could maintain its stability from physico-chemical and microbiological destruction during 5 months storage.
