Dealing with mycotoxin-contaminated forages
Midwest Forage Association
Every ton of feed discarded from the farm has to be replaced with another one that may need to be purchased. Current farm finances make it difficult for livestock producers to be overly critical of forage quality. It is not unusual for tough economic times to be followed by higher incidence of nutritional problems, sometimes a result of borderline risky decisions. Moldy forages are sometimes blended with “clean” ones in an effort to dilute overall mycotoxin concentrations. Using multiple feeds generally dilutes the toxins of a given feed, resulting in a safer diet. On the other hand, because the effect of toxins can be additive, multiple contaminated feeds can compound the toxic effect of a diet.
