"Concern about rising levels of mycotoxins in feed
grains has driven innovations for more reliable testing methods," said Eugene Rodberg, senior product
manager - feed quality, Kemin Animal Nutrition,
and Health - North America. "With the right testing
equipment, producers know in minutes if their grain

mycotoxins. Once the types and levels of toxins are
known, there are products producers can add to their
feed to address the issue - including clays and zeolites,
activated charcoal, yeast cells, biologics and enzymes.
These compounds are not all equal, so it is important to

negative impact on animal performance in feed conversion, mortality, and fertility rates, said Pat Frasco,
director of corporate accounts for Neogen.
"Maximizing feed performance is vital at a time of
tight margins for livestock producers," he said.
Frasco said that in addition to the major six mycoWR[LQV DÀDWR[LQ '21 )XPRQLVLQ 27$7+7 DQG

ergot alkaloids.
"The incidence of ergot contamination has increased
in places like Europe, Canada and the northern U.S. that

raise small grains, especially rye," he said. "Once ergot

Enterprises processing grains for either human foods,
pet foods, livestock production, and aquaculture must prevent the introduction of mycotoxin-contaminated grain

"Where lower levels of mycotoxins are allowed into the
facility, great care regarding processing impacts on both
concentration and/or dilution of mycotoxins must be well
known and documented," he said.
Since ingredients may account for 70% to 90% of
the cost of producing feeds, managing ingredient quality is important in ensuring high feed mill productivity,
said Ryan Whipkey, product manager for life sciences,
EnviroLogix.
Whipkey also advised that to control variation in
feed ingredient quality, the feed mill must have a robust QA/QC policy that describes what, when and how
to measure ingredient quality.
"On-site measurement of bulk ingredients at the
point of delivery enables feed mills to segregate lowquality ingredients and appropriately re-formulate
