Alltech 2017 Harvest Analysis = High Mycotoxins in Corn Silage

In 2016, corn growers faced challenges from mycotoxins and Alltech believes those challenges seem likely this year.

Corn silage samples from across the entirety of the U.S. have shown extremely high levels of mycotoxins, particularly deoxynivalenol (DON), type A trichothecenes (T-2), fusaric acid and fumonisin. It is important to note that once there are mycotoxins in the crop, they will not go away. There will be higher levels of mycotoxins on farms practicing monocropping of corn, as opposed to those farms that are rotating crops or using deeper tillage methods.

Samples submitted to the Alltech 37+® mycotoxin analytical services laboratory between Sept. 1 and Nov. 1, 2017, show that grains contained mixtures of mycotoxins, including DON, fusaric acid and fumonisin. Forages such as corn silage, barlage and haylage samples also contained multiple mycotoxins in 2017, including DON, fusaric acid, T-2 and fumonisin.

“Understanding the risk of mycotoxins and combinations of mycotoxins, even at lower levels, allows livestock owners and managers to institute a management program for more optimum performance and health,” said Dr. Max Hawkins, nutritionist with the Alltech® Mycotoxin Management team. “Testing feedstuffs and finished feeds is paramount to putting this management program in action.”

Alltech will be hosting a webinar to review the 2017 Alltech Harvest Analysis results for the U.S. with Dr. Max Hawkins on Dec. 14, 2017 at 10:00 a.m. ET. Learn more about these results here.
