BIOMIN Mycotoxin Survey in US Corn Silage Update: April 2021 Update
Our latest update from the annual Biomin® PROcheck mycotoxin survey comprising 74 samples of corn silage is here.09.04.2021
US Silage Report
Each sample was tested for 6 major mycotoxin groups of:
A-Trichothecenes (A-Trich): T-2, HT-2, Neosolaniol, Diacetoxyscirpenol
B-Trichothecenes (B-Trich): Deoxynivalenol (DON/Vomitoxin), Acetyl-deoxynivalenol, Nivalenol, Fusarenon X
Fumonisins (FUM): B1, B2, B3
Aflatoxins (Afla): B1, B2, G1, and G2
Ocharatoxin A (OTA)
Mycotoxins can occur throughout the whole corn plant, not just the grain. Therefore, this corn silage report will focus on detail specific to mycotoxin occurrence and contamination of this important feedstuff. The report will be refreshed with new data every quarter as corn silage samples are received and analyzed.
USA Corn Silage
- 74 corn silage samples were tested
- 99% of samples were positive for at least one mycotoxin vs. 97% in 2019
- 59% of samples had more than one mycotoxin, vs 52% in 2019
- Average contamination levels:
- Overall, the mycotoxin contamination in 2020 corn silage appears to be relatively similar in comparison to 2019 corn silage with B-Trich levels holding steady, lower occurrence of ZEN, but A-Trich and FUM are elevated.
