Abstract

Five trials were conducted to compare the effectiveness of commercial anti-mould agents on the prevention of mouldiness in partially dehydrated palm oil mill effluent (POME) which contained 20-30% dry matter. The anti-mould agent Mycostatin-20 was effective in checking mould growth but ineffective in preventing fermentation of POME. Sodium benzoate and benzoic acid at 2 g/kg level respectively were effective for these two functions. It is suggested that preservation should only be carried out with POME sample alone before being mixed with other feedstuffs. The feed
mixture should be fed to animals immediately.
