In vitro profiles of a diet containing concentrate with rice bran and Arenga pinnata by-product fermented with Pleurotus ostreatus
Main Article Content
Abstract
The results showed that the ration containing concentrated with the fermented rice bran and Arenga pinnata by- product (Arenga sago dregs) significantly affected (p<0.05) pH and IVDMD. There were not significantly affected (p>0.05) on NH3, VFA, IVOMD, protozoa population levels, total bacteria, partial VFA, or methane gas. However, the addition of ration with concentration containing 10% rice bran and Arenga sago dregs fermented by Oyster mushroom (Pleurotus ostreatus) increased microbial protein synthesis by about 9.35 mg – 15.82 mg/ . Feeding a diet containing 15% fermented rice bran- Arenga sago dregs can be tolerated and is found to be optimal, as the digestibility values of dry matter, organic matter, total VFA, and NH3 concentrations are found to be a normal limits.
