NEWS FEED & ADDITIVE MAGAZINE December 2024 13 2024 U.S. HARVEST ANALYSIS Preliminary analysis of corn silage samples in the U.S. reveals a high increase in mycotoxin contamination compared to 2023, with all samples containing two or more mycotoxins. “The weather pattern for 2024 is a prime driver for the change in corn silage mycotoxin risk. The precipitation over the upper Midwest started early and, in many areas, delayed planting or caused replanting,” explained Dr. Max Hawkins, Technical Support Manager with Alltech’s mycotoxin management team. “This excess moisture is a stimulant for Fusarium mould growth, which can produce mycotoxins such as type B trichothecenes, emerging mycotoxins and zearalenone. Overall, the numbers of mycotoxins per sample are 8.3 for 2024 versus 5.3 for 2023. The risk equivalent quantity (REQ), or risk estimate, from all the mycotoxin present is 201.6, or higher risk, vs. 122.7 for 2023.” 2024 CANADIAN HARVEST ANALYSIS Recent mycotoxin testing in Canadian silages and grains, conducted as part of the Alltech 2024 Canadian Harvest Analysis, is revealing significant regional variability in contamination levels, with corn silage showing particularly high risks. “Canada has experienced a change in weather patterns from last year, particularly of note the greater rainfall across the prairies,” pointed out Dr. Alexandra Weaver, Global Technical Support for Alltech. “As a result, there appears to be greater mycotoxin risk in the Western Canada 2024 harvest than last year. We’ve also noticed continued risk from deoxynivalenol and zearalenone in Eastern Canada, which can impact animal health and performance.” Read more>> Gut health is more than a gut instinct.
