| Biotransformation of vomitoxin investigated in the present study indicated that microorganisms from contents of the large intestine of chicken (CLIC) were able to reduce the epoxy group in vomitoxin more efficiently than could those from rumen contents or soil.;High concentrations (143 or 1419 ppm) of vomitoxin in the incubation media enhanced the initial transformation rate. A pH of 5.2 in the incubation medium completely inhibited degradation of the toxin, while pH values of 5.72 to 6.91 did not affect the biotransformation reaction.;When moldy corn naturally contaminated with vomitoxin was incubated with CLIC in liquid culture, approximately 50% of the toxin was transformed to DOM-1 in 96 h. However when CLIC was mixed directly with the air dry corn, no transformation of vomitoxin occurred.;When young pigs were fed a diet containing moldy corn treated with CLIC, their performance was significantly improved compared with that of pigs fed a diet containing untreated moldy corn.
