Research – Drought-stressed maize is more likely to present mycotoxin risk.

The extremely hot weather this summer has meant many maize forage crops have grown under drought stressed conditions, which has increased the likelihood of in-field mycotoxins developing, according to UK agricultural supply company Wynnstay.

Wynnstay dairy specialist Beth Parry urges dairy farmers to be aware of this heightened mycotoxin risk when feeding maize forage this autumn and winter.

“With potentially limited forage stocks following a difficult growing season, farmers are going to need to maximise feed utilisation and digestion to ensure performance isn’t impacted too greatly this winter,” she said.

“In-field mycotoxins are more likely to be present in silages if the crop experienced any kind of stress, such as growing in drought conditions, because moulds and fungi will have had more opportunity to take hold and produce mycotoxins,” she added.
