Prepare for the risk of mycotoxins
Mycotoxins are a concern for livestock producers, as they influence feed quality and animal safety. Increased moisture can allow fusarium molds to flourish, producing a variety of mycotoxins that include deoxynivalenol (DON), fusaric acid, T-2, HT-2 and zearalenone (ZEN). Samples of the 2019 corn silage from across the United States is indicating the presence of high levels of mycotoxins, reports the Angus Beef Bulletin.
The samples have included an average of 7.13 mycotoxins, with a range of 2 to 14 mycotoxins per sample. In 86.6% of the samples, DON was present; 99.5% contained fusaric acid; and 94.1% tested positive for emerging mycotoxins, including beauvericin, moniliformin, enniatins, phomopsin and alternariol. These emerging mycotoxins will add to the risks potentially affecting rumen function, gut health and immune response. A point of interest is that ZEN was found in 48.9% of the samples and has become increasingly prevalent during the past two years.
