Digestibility of Corn-Mungbean Diet in Pre Starter Broiler as Affected by Multi-Enzymes

Abstract

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); D_EA1 [basal diet+A1 (protease 7500 HUT and cellulase 44 CMCU/gram)]; D_EA2 [basal diet+A2 (protease 7500 HUT and cellulase 44 CMCU/gram)]; D_EB1 [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 D_EC1 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.
