Why do mycotoxins
flourish?
• Agronomy
• Climate: Rainfall, temperature
• Plant stress: Disease, insects,
birds, weather damage

Risk equivalent quantity (REQ)
WHAT IS THE REQ?
•An evaluation of the total toxicity of a given mycotoxin
mixture based on the amount of individual mycotoxins

Summary
Risk assessment
• Opportunity to link mycotoxin risk to animal
performance through use of ALLTECH 37+ REQ
• Provides a holistic approach for analysis, reporting, and
controlling multiple mycotoxin contamination as well as
understanding the impacts of mycotoxins on animals
Your flock is your business. Protecting it is ours.
