In-vitro Efficacy of Sakura Block Plus Supplementation in Oil Palm Fronds (OPF) on Rumen Fermentation, Nutrient Digestibility, and Gas Production

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.

Supplementation of Sakura Block Plus in Beef Cattle Fed with Palm Fronds and Its Effect on Nutrient Digestibility

“…Sakura Block Plus, a modification of Sakura Block incorporating earthworm flour and palm kernel cake, exhibits excellent nutritional content for rumen microorganism growth (Jarmuji et al, 2021b). In vitro testing of Sakura Block Plus supplementation on palm frond feed has shown increased rumen fermentation products and reduced methane gas production (Jarmuji et al, 2022). Economically, supplementing Sakura Block Plus at 400 g/day in the fattening of 2-year-old Kaur cattle can yield a Revenue Cost Ratio (R/C) of 3.57 (Jarmuji et al, 2023b).…”
