Can moldy hay cause colic?

Moldy hay can cause digestive upset that can lead to abdominal pain (colic), sometimes serious. In rare cases, hay containing toxic molds can cause life-threatening illness.

Will moldy silage hurt cows?

A common toxic effect in cattle exposed to any storage-produced mycotoxins is a change in ruminal flora make-up, which alters rumen fermentation. Long-term feeding of moldy silages can produce local inflammatory responses that may lead to rumenitis.

Rained-on hay often has relatively high protein values compared to fiber content unless there's great leaf loss. Leaves contain a lot of the plant's protein. As soluble carbohydrates leach, structural fibers make up a greater percent of forage dry matter. The digestibility of rained-on hay can decline 6 to 40 percent.

At what temperature does hay mold?

“Hay bale temperatures of 120°F to 130°F will likely result in mold growth and will make the protein in the hay less available to animals,” Hartschuh says. While these temperatures will not cause fires, continued mold growth can raise temperatures to dangerous levels.

Can hay get wet and still be good?

If rained-on hay is not again dried fully, mold and mycotoxin growth can occur which can put livestock health at risk. Furthermore, baled wet hay can combust due to the temperature increase caused by microbial growth - putting a producer at risk of barn fire.
