Abstract

The conversion of agrictilhu:e to non-agriculture land tend to increases, so that to cause the increasing of land using to crop production. In turn, the land which available to forages production become to limited. Those to cause the adequate forages supply very difficult to be realized. As the °flint lo meet the roughage requirement, the farmer usually use the crop residues, among other sugar cane lop. Because its maturity, crop residues quality as feed not adequate. It be caused by the low of crude fiber digestibility, so that its total dry matter digestibility is also low. On the other hand, crude fiber is the mitten. component of dry matter of crop residues. Crude fiber digestibility in crop residues is low, because cristallinity and degree of I ignification of cellulose is high. Ammoniation and fermentation can make the del ignification, depolitnerization, and decreasing of cristallinity of cellulose. Combination treatment between airimoniation and fermentation will increases the utility of crop residues as feed. This investigation was conducted to study the effect of combination between chemical treatment (tunmoniation) and biological frea1111011( (fermentation by Trichoderma reesei) on the utility of sugar cane lop as nunintuu feed. Those in this case to he reflected by in meet) crude fiber digestibility. The sugar cane top van. BZ-48, urea as ammonia source, T reset isolate, rice bran an substrate for sporulation and tistulated yearling male cattle P(1, were used as experimental material. Sugar cane top was cut over 2 cm and MINI. AIIIInoniali on process was done to them with ammonia levels were : 2, 4, and 6 percent (treatment motor I). After that, fermentation process was conducted by Triehoderma reesei with incubation periodes were : 0, 2 and 4 weeks ( treatment lector 11 ). 11/ sacco digestion technique was applicated by nylon bag with incubation time 48 hours_ Crude fiber digestibility was calculated based on crude fiber content analysis on sugar cane top and undigested dry matter residue by Wendee method. The collected data were statistically analyzed by analysis of varitmce with 4 x 3 factorial treatment pattern in completelly randomized design. Investigation result showed that fermentation by T. wesei (up to 4 weeks incubation) and tmunoniation (up to 6 % ammonia) tend increases in :;cfcco crude fiber digestibility of sugar cane top. Combination treatment between fermentation (1 weeks incubation) and ammoniati on % ammonia) to ineretme 1.eitnetitation effectivity significantly (P <0.05), namely : 50.25 % vs 31.37 % in untreated aangar cane top.

Seliagai bagian dari tantalum tuti, lcualitas pertanian sebagni pakan ticlak memadai. Hal tersebut antara lain disebabkan rendalmya kecernaan serat kasar, yang berdampak pada renclahnya kecernaan bahan kering total.
