ABSTRACT: The present study was investigated the optimal time and apparent digestibility coefficient of enzyme from Nile tilapia gastrointestinal tract and cellulase crude extract from Trichoderma viride for corncob digestion. The crude extract from 15 g Nile tilapia and cellulase from Trichoderma virdie were took to digest corn cob at 0, 60, 120, 180, 240, 300 and360 min.The results showed that the optimal time of crude extract from Nile tilapia digested corn cob that detected by the glucose content, percentage of dry matter, protein fiber and fat were 300,5, 360, 120 and 180 min, respectively.Moreover, the optimal time of cellulase from Trichoderma viride for corn cob digestion which detected by the percentage of dry matter and glucose content were 240 and 360 min, respectively. This study indicated that the optimal time for corn cob digestion of crude extract from Nile tilapia and cellulase from Trichoderma viride were 360 min. In addition, corn cob can be used as feedstuff for Nile tilapia diet.
