Here's a timely reminder from the University of Wisconsin on the dangers of prussic acid poisoning when feeding sorghum, sorghum sudangrass, or sudangrass after a frost.
Here are a few highlights from the article:
- Young regrowth is the most dangerous stage (18-24 inches).
- As a precaution, don't feed sorghum/sorghum sudangrass silage for at least three weeks after storing.
- Hay stored for 2 months or longer is generally safe to feed.
- Allow 7-10 days after a light frost before feeding green-chop or grazing.
