Mycotoxins are proving to be a challenge for livestock feeders this year.
Among the worst is the mycotoxin DON, also known as deoxynivalenol or vomitoxin. It impacts the gastrointestinal tract and is the subject of a video on Biomin’s Mycotoxin Channel on YouTube.
In the clip, Isabelle Oswald, head of immuno-mycotoxicology at the French National Institute of Agricultural Research, explains what happens in the animal’s intestine as a result of DON. She specializes in researching the impact of mycotoxins on the immune system, particularly in pigs.
DON is among the more commonly occurring of Fusarium mycotoxins often associated with illness in farm animals or humans. Once ingested, DON weakens the intestine significantly, altering its protective barrier function and allowing more contaminants to enter the lumen of the gastrointestinal tract.
Oswald explains that from a weakened gastrointestinal tract, bacteria are then able to translocate themselves to the rest of the animal. She also addresses the long-term effects of mycotoxins on pigs and ways to analyze their response in the animal’s gastrointestinal tract.
Also on the Mycotoxin Channel, you will find Webinars that address specific questions on mycotoxin problems and related management issues around the world. Topic sections include analysis, mycotoxin risk management, mycotoxins in general and symptoms.
