IMPROVING PHYSICOCHEMICAL CHARACTERISTIC AND PALATABILITY OF KING GRASS (Pennisetum hybrid) SILAGE BY INOCULATION OF Lactobacillus plantarum - Saccharomyces cerevisiae CONSORTIA AND ADDITION OF RICE BRAN

ABSTRACT: This study was conducted to determine the effectiveness of inoculants consisted of lactic acid bacteria Lactobacillus plantarum (Lp) and yeast Saccharomyces cerevisiae (Sc) combined with the addition of rice bran on the physicochemical characteristics and palatability of king grass (Pennisetum hybrid) silage. The experiment was arranged in the randomized factorial design (3x3) consisting of the inoculants treatments (control, Lp, Lp+Sc) and the different level of rice bran addition (0, 5 and 10%) which contained 3 replications in each treatment. The measured variables were physicochemical characteristics i.e. color, odor, pH, lactic acid, Fleigh points (quality indication score), and palatability of silage. Inoculation of Lp and Lp+Sc improved silage odor and reduced fungal contamination. Silage treated by Lp+Sc and rice bran (5-10%) resulted in low pH and high lactic acid concentration and Fleigh points significantly (P<0.05). However,the interaction between inoculants and rice bran treatment was not significance (P>0.05). Either inoculationor addition of rice bran tended to enhance the palatability of silage in cattle. It concluded that the additionof inoculants L. plantarum and S. cerevisiae with/without the addition of 5-10% rice bran could improve the physicochemical characteristics of silage and its palatability to cattle.
