ABSTRACT
This study aimed to obtain the level of sakura block plus as an in-vitro supplementary feed in Oil Palm Fronds (OPF) feed on optimizing rumen fermentation products, digestibility of nutrients, and gases production. Sakura block plus is a modification of commercial sakura block by using earthworm flour as a source of protein as a substitute for rice bran. The treatments were arranged as follow: P0= OPF + concentrate + 10% commercial sakura block, P1 = OPF + concentrate + 6% sakura block plus, P2 = OPF + concentrate + 8% sakura block plus, P3 = OPF+ concentrate + 10 % sakura block plus, P4 = OPF + concentrate + 12% sakura block plus, P5 = OPF+ concentrate + 14% sakura block plus. Supplementation of sakura block plus in OPF was able to increase rumen fermentation products, digestibility of nutrients, and production of gases. The increase in the treatment of OPF supplemented with sakura block plus at a level of 12% was higher compared to the other treatments.
