The current study aimed to investigate the effect of formic acid, S. cerevisiae or the combination of both on the growth performance and serum indices of the Indonesian indigenous crossbred chicken (IICC). Two hundred of the IICC were allotted to four groups including CONT (basal diet exempted from additive), FORMIC (basal diet administrated with formic acid), SACCH (basal diet with S. cerevisiae) and FORSAC (basal diet with the blends of formic acid and S. cerevisiae). |
