Organoleptic Quality and Nutrition of Rice Straw Silage Utilizing Local Microorganisms (MOL) of Cattle Rumen Fluid at Different Inoculum Levels
Keywords:Rice Straw, local microorganisms (MOL), Rumen Fluid, Organoleptic, Nutrition
Feed quality very depends on changes in the weather where in short rainy conditions the feed is abundant, mean while, long dry conditions cause feed availability to be limited. One of the abundant feeds is rice straw, but the use of rice straw needs to be considered for its nutritional content, thus its utilization requires to be processed first. This study aimed to utilize local microorganisms (MOL) of Bali cattle rumen fluid at different inoculum levels on the quality of fermented rice straw silage to over come feed shortages in dryland. The study used a completely randomized design (CRD) with 4 treatments and 4 replications, namely R0: Rice Straw + Rice Bran 10% + molasses 3% (Without MOL of cattle rumen fluid/control); R1 : Rice Straw + Rice Bran 10% + molasses 3% + MOL of cattle rumen fluid 5%; R2 : Rice Straw + Rice Bran 10% + molasses 3% + MOL of cattle rumen fluid 10%; R3: Rice Straw + Rice Bran 10% + molasses 3% + MOL of cattle rumen fluid 15%. The percentage of molasses and cattle rumen fluid was adjusted to the weight of chopped rice straw. Data were analyzed using analysis of variance (Anova). The results showed that the treatment had a significant effect (P<0.05) on the organoleptic quality (color, texture, smell, presence of fungi and pH) and organic matter, crude protein, extract eter, crude fiber, carbohydrate, nitrogen free extract and gross energy (nutritional content) of rice straw silage, dry matter and gross energy had no significant effect (P>0.05). It can be concluded that the higher MOL of cattle rumen fluid level use, the greater organoleptic quality and nutritional content of rice straw silage obtained
