PENGARUH PENGGUNAAN DEDAK FERMENTASI TERHADAP KADAR LIGNIN DAN SELULOSA SILASE RUMPUT GAJAH (Pennisetum purpureum)

Abstract

Silage is a fresh forage preservation. Fermented rice bran can be used as a starter to accelerate the process of making silage fermentation. The aim of these study was to determine the effect of fermented rice bran usage toward the levels of lignin and cellulose in elephant grass silage. The research was held at Mekar Jaya Farmer Group in Cikembulan, Pangandaran and Ruminant Nutrition and Food Chemical Laboratory of Animal Husbandry Faculty of Padjadjaran University on November 2019 to Januari 2020. Experimental method was used with completely randomized design (CRD) with 3 treatments and 6 replications. The treatments consisted of P1 (1% fermented rice bran), P2 (3% fermented rice bran), and P3 (5% fermented rice bran). The results showed that the use of various doses of fermented rice bran in making silage of elephant grass have significant affected on lignin and cellulose silage levels. Used of 5% fermented rice bran dose produced the lowest lignin silage content of elephant grass (3.29%) with the lowest cellulose content (32.91%) while the 1% dose produced the highest cellulose content (40.42%) with the highest lignin content (4.87%).
