Dry matter, crude fiber and nitrogen free extract contents of Seligi leaf (Phyllanthus buxifolius) powder fermented with different duration and probiotic's dose as a fish feed ingredient

Seligi (Phyllanthus buxifolius) is a herbaceous plant which still rarely used as feed additives. Seligi has a high crude fibre and low protein so it needs to be improved by fermentation using probiotics. The fermentation process is influenced by duration and dose. This study aims to determine whether there are effects and interactions of duration and dose of probiotics on the content of dry matter, crude fibre and nitrogen free extract (NFE) in Seligi leaves. This study is experimental research with factorial completely randomized design with 2 factors, namely the duration of fermentation, consisting of 2 treatments, 5 and 7 days, while the other factors are the dose, consisting of 4 treatments namely 0%, 2%, 4% and 6%. The results showed that there was an effect of fermentation duration on dry matter, which on day 5 produced the highest dry matter, but there was no dose-effect and no interaction. In crude fibre, there is an effect of probiotic dose where at a dose of 2% it produces the lowest crude fibre, but there is no effect on the duration and there is no interaction. In the NFE, there was no influence and interaction between time and dose.
