65: Beyond Fertility | Zearalenone’s Impact on Herd Health

Zeralanone is often labeled a reproductive mycotoxin, but that barely scratches the surface. This reproductive mycotoxin, is an estrogen imposter that disrupts fertility, immunity, liver function, and overall metabolic stability.

In this episode, Dr. Larry Roth explains why zearalenone is fat-soluble, how it can be stored and released during post-calving fat mobilization, and why its metabolites may be even more damaging than the parent toxin.

Learn how it contributes to cystic ovaries, early embryonic loss, cows showing heat signs while pregnant, and inconsistent reproduction, as well as why some traditional binders can make things worse.

If pregnancy rates aren’t matching expectations, this episode shows why zearalenone could be the hidden disruptor and how targeted protection like DTX helps prevent absorption before damage occurs.
