摘要：Feed enzymes were developed to improve nutrient utilization in monogastric. This research was conducted to study several commercial multi-enzymes and our own multi-enzymes products to determine their effect on dry matter digestibility and performance of pre-starter broiler fed corn-mungbean base diet. An in vitro test to determine the dry matter digestibility of the diet was also carried out. Eighty Lohman MB-202 day old chicks were randomly assigned into eight treatment diets i.e., Dc (control basal diet); DEA1 [basal diet+A1 (protease 7500 HUT and cellulase 44 CMCU/gram)]; DEA2 [basal diet+A2 (protease 7500 HUT and cellulase 44 CMCU/gram)]; DEB1 [basal diet+enzyme B1 (endo-1,4-a-xylanase 5500 visco units and endo- 1,3/4-a-glucanase 500 AGL units/ml)]; DEB2 [basal diet+B2 (endo-1,4-a-xylanase 5500 visco units dan endo- 1,3/4-a-glucanase 500 AGL units/ml)]; DEC1 [basal diet+enzyme C1 (amylase 2,5 U/ml, protease 77 U/ml and xylanase 91 U/ml)]; DEC2 [basal diet+enzyme C2 (amylase 2,5 U/ml, protease 77 U/ml and xylanase 91 U/ml)]. The results showed that enzymes addition could not improve in vivo dry matter digestibility (DMD). However feed intake and feed conversion ratio was lowest in DEC1 with no difference in body weight. In vivo digestibility did not correlate to in vitro digestibility. Multienzymes did not improve performance and dry matter digestibility of corn-mungbean base diet in prestarter broilers.
