How Accurate and Precise are Quick Tests and Labs for Analyzing DON?
Mycotoxin presence in feedstuffs may be unavoidable at times; having confidence in the testing methods used to measure those levels doesn’t have to be. High mycotoxin levels in feed grains can negatively affect the overall health and performance of animals consuming the feed, resulting in a loss of profits. To make informed feeding decisions, it is crucial to accurately and precisely test grains for mycotoxins.
With the many lab and quick test options on the market, it can be difficult to determine which is the most reliable. With this issue in mind, NutriQuest performed a ring test to determine the variability and accuracy of labs and quick tests currently on the market for the analysis of deoxynivalenol (DON) – also known as vomitoxin — in corn and dried distillers grains plus solubles (DDGS).
Why does it matter?
The DON ring test demonstrates that, when testing for mycotoxins, the quick test or lab used largely affects the reliability of the data. This is especially concerning when seeing that a 2 ppm difference considerably changes how grain is handled.
