Abstract

The efficacy of yeast cell wall in the adverse effects of zearalenone (ZEN) in in vitro gas production was determined.
The experiment consisted of 4 treatments: 1) diet alone, 2) diet plus 0.5 mg/kg ZEN, 3) diet supplemented with 0.5% yeast cell
wall, and 4) diet supplemented with 0.5% yeast cell wall plus 0.5 mg/kg ZEN. ZEN suppressed the Fibrobacter succinogenes and
Ruminococcus albus populations (P<0.05), but did not interfere with the in vitro gas production. In contrast, yeast cell wall
increased the F. succinogenes and R. albus populations and in vitro gas production of insoluble fractions (P<0.05). Moreover,
ZEN and yeast cell wall did not affect digestibility, VFAs, NH₃N, or B. fibrisolvens population. The efficiency of yeast cell wall
on ZEN decontamination was unclear. In conclusion, ZEN reduced major fibrolytic bacterial populations, while yeast cell wall
could alleviate the ZEN adverse effect and enhance in vitro gas production.
