Pemanfaatan Limbah Berserat Dalam Konsentrat Untuk Sapi Jantan Umur Satu Tahun
ABSTRACT: A series of
experiment had been conducted to improved the quality of rice straw, rice bran
and cassava solid waste through biological pretreatment using several species
of microbes. Based on the digestibility and the fermentation product, indicated
that 30 percent of rice straw, 35 percent of rice bran and 35 percent of
cassava solid waste was the optimal ratio for concentrate formulated. The
present experiment was carried out by experimental method with Completely
Randomized Design, on twelve yearling male cattle of Ongole grade. The
treatment tested were 3 physical form of the concentrate : (1) unfermented
mesh; (2) fermented mesh and (3) fermented pellet. The variables measured were
: energy and protein digestibility, rumen fermentation product, nitrogen
balance and daily body weight gain. The digestion and balance trial were
carried out by the Total Collection Method. The analysis of covariance shown,
that there were significantly effects of the treatment tested whether upon the
protein and energy digestibility, the nitrogen balance (P<0.01), nitrogen
ammonia production and daily body weight gain (P<0.05), but there was no
significantly effect on the Total Volatile Fatty Acid and the proportion of the
individual VFA (P<0.05). Based on the all variables measured, it was
indicated that fermented pellet was the best concentrate (composed by 30% of
fermented rice straw, 35% of fermented rice brand and 35% of fermented cassava
solid waste).
