Dealing with Wet Hay

It seems like we’re always dealing with either drought or too much moisture to put our hay up.

Wet hay, either because of initial moisture or because of moisture from rain can have serious issues ranging from loss of nutrition value to forage toxicity and risk of stack fire.  To minimize these risks, it’s important for those growing hay and those feeding hay to understand that actually happens inside a wet hay bale.  The information below provides a good background on all these issues.
