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.
