feed hay mold

Asked November 10, 2016, 1:43 PM EST

We have 4 tons of orchard grass hay in two stacks in our barn. Mold is beginning to form on the outside of the bales. Is there a treatment to stop its progress? Are there options other than discarding the moldy parts as we go?

Most of the time, the mold that forms on the outside of bales is due to humidity issues, which can be difficult to control in our climate. Some barns and storage facilities are more conducive to mold generation than others. Consider ways to increase air flow or improve ventilation to reduce humidity inside the storage area, if possible.

You could consider composting the moldy hay or using it for mulch. Bedding for poultry may be another option. Information on types of mold and options for utilizing the hay is available on this fact sheet: http://www.extension.uidaho.edu/forage/Fact%20Sheets/Moldy%20hay%20in%20Idaho.pdf
