we purchased about 300 ton of hay that has been tested and found to be very high in potassium. The feed store we deal with told us not to feed the hay to our bred cows, most of them due the end of Feb. through the end of March. Another feed outfit we buy our salts and minerals through told us that they could make up a mix to supplement the hay and that would make the hay okay to feed. Do you have any knowledge about hay with too much potassium?
