Kandungan nutrien, fraksi serat dan nutrient value fermentasi jerami kacang tanah (Arachys hypogaea) pada level nira lontar (Borassus flabellifer) yang berbeda

Objective: Peanut straw is abundantly available and still contains the nutrients needed by livestock but has high crude fiber content. Therefore, it processed using fermentation technology palm sap. The nutrient content fraction of fermented peanut shells at different levels sap aim research. Methods: Completely Randomized Design (CRD) used with 4 treatments 6 replications, namely: JKT0 = without sap, JKT5 + 5% JKT10 10% JKT15 15% for 21 days. research variables were resulted proximate analysis, fraction, value . analysis one-way variance Duncan's Multiple Range Test (DMRT). Results: Increasing use up to in rice led a 15.59% decrease dry matter, 7.33% increase nitrogen-free extract (BETN), 19.67% ash, an 6.13% NDF, .99% ADF, 7.57% cellulose, 45.45% hemicellulose, (DMI, DMD, RFV) no effect on protein, fiber, fat lignin. gives optimal results. Conclusions: process affects matter content, BETN, impact fat, lignin best level 10%.
