The Effect Fermentation of Local Agroindustry Waste Using Cellulolytic Bacteria Cellulomonas on Nutrient Content as Feed Stuff

Abstract

This study aimed to evaluate fermentation of local agro-industry waste to produce CSCF as alternative feedstuff nutritious and palatable for rabbit. Experimental research method that uses a completely randomized factorial design 3x4 is cellulolytic bacteria colonies concentration and duration of incubation. Data were analyzed for variance and Duncan's Multiple Range Test (DMRT) to determine differences between treatments. The results showed that increasing the use of cellulolytic bacteria concentrations and the incubation time in the fermentation can improve CSCF quality with CP rose and lowering the content of CF, NDF, ADF and cellulose. The optimum fermentation CSC are using a treatment concentration of 10⁸ cfu /g DM and incubation 8 days, the nutrient content of OM 92.64 % ; CP 11.55 % ; EE 31.29 % ; CF 17.34 % ; NDF 28.23 % ; ADF 18.33 % ; cellulose 8.89 % and lignin 7.13 %.
