The objectives of this work were to evaluate the roles of sheep rumen liquor enzymes on its capability to reduce the crude fiber contant and enhance the apperent digestibility of coconut cake meal (BK) for common carp Cyprinus carpio. The work comprised by two stages experiments. In experiment I, BK was hydrolized with 0, 25, 50, 75, 100, or 125 ml enzymes/kg BK for 0, 12, and 24 hours, respectively. Thereafter, proximate compositions of BK were analyzed. In experiment II, hydrolyzed BK (BKe) contained the least crude fiber content from the result of experiment I was tested for its digestibility. It was found that BK hydrolyzed with 125 ml enzymes/kg BK for 24 hours had the lowest value of crude fiber content, and highest value of glucose content. In this treatment, crude fiber content was decreased from 14,34% to 6,98%, while the glucose content was increased from 0,014% to 0,464%. The apparent digestibility of BKe was found to be higher than BK. The total digestibility, protein carp was 63,92% and 54,58%, 79,53% and 65,17%, 72,2% and 49,17% for BKe and BK, respectively. It was concluded that sheep rumen liquor enzymes could reduce the crude fiber content of BK, and enhance its apparent digestibility for carp Cyprinus carpio.
