by-products for feedstuffs. Rice straw and â€œonggokâ€ represent the by-products that
very potential to use for feedstuffs. However these by-products have low digestion
value for livestock. Therefore processing of the by-products before use is essensial
to increase its quality. The experiment was conducted for 7 weeks to investigate
the effects of feeding diets containing rumen liquor treated-rice straw or rumen
liquor treated-onggok on the performance of local male sheeps. Parameters
measured were feed intake (g/head/day), weight gain (g/head/day), and feed
conversion. Data from randomized complete block design were analized using
ANOVA and if its showed significantly different contras ortogonal test was used.
The result showed that the treatments significantly (P<0,05) affected feed intake,
weight gain, and feed conversion. R2 and R3 treatments significantly (P<0,01)
increased feed intake compared with R4 and R1 treatment, while between R2 and
R3 treatments, and R1 and R4 treatments were not different. It can be concluded
that treament of rumen liquor to rice straw could improve its nutritive quality which
was proved by good performance of sheeps fed diets containing rumen liquor
treated rice straw.
