Five minutes to better prepare against mycotoxins


It must be a mycotoxin problem… Can we rely on the test results? Which product should I use? So many questions, it’s not easy to know where you stand in the complex world of mycotoxins!

In collaboration with Lactanet, Professor Younès Chorfi’s team at the Faculty of Veterinary Medicine is leading a project to develop tools to help with decision making on the effects of mycotoxins and the efficiency of the antimycotoxin treatments. 

For these tools to adequately meet the actual needs of producers, agronomists and veterinarians, we will need your help in responding to this short 5 minute survey.

About Mycotoxins

Mycotoxins are complex and toxic organic compounds produced by mold. They are considered to be a major risk factor for both animals and humans. Contamination can take place in the field, before harvest or at storage.

While certain preventative measures can be taken to reduce the prevalence, it is very difficult to prevent the contamination of feeds, in particular when the climate conditions are favorable to the development of mold in crops.

The Impact on Dairy Cattle

The presence of mycotoxins in livestock feed can be a major problem in dairy production. Mycotoxins can decrease immune efficiency, bring about increased sensitivity to infection and disease, interfere with reproduction and reduce zootechnical performance.

The symptoms of mycotoxicosis are varied and not very specific. In cattle, it can ressemble digestive problems, immunosuppression, a drop in feed intake, weight gain, and milk production as well as an increase in reproductive problems – embryonic mortality, frequent abortion, and return to heat even if the cow is pregnant. Overall these factors can make life difficult for producers, agronomists and veterinarians when it comes time to make decisions.
