Nutrient Content of Cassava Dregs and Rice Bran Fermented with Aspergillus niger

The aim of the present study was to investigate the nutrient content and the potential application as feed from cassava dregs and rice bran
fermented with Aspergillus niger. The research used a One-Way Completely Randomized Design on two substrate treatments including cassava dregs
and rice bran fermented with Aspergillus niger, each with 3 replicates. The obtained data between control and substrate fermented with Aspergillus niger
were analyzed using t-test. Both cassava dregs and ricebran substrates were suitable for Aspergillus niger fermentation, but crude protein increase was
higher in ricebran (8.44%) while crude fiber decrease was higher in cassava dregs (20.93%) followed by increasing 19.53% nitrogen free extract (NFE).
It was concluded that ricebran fermented with Aspergillus niger is a potential protein feed with 31.54% crude protein, while cassava dregs fermented
with Aspergillus niger is a potential energy feed with 67,37% NFE.
