Certain types of horse hay are more popular in specific areas because locally grown hay is often much more affordable and easier to come by.
Orchard grass hay is a staple among horse hays, and most horses absolutely love it. This type of hay has a protein content of 10% to 12% and a high-calorie content.
Oat grass hay is another good choice for most horses, even those that do not fare well on oat grain food. Oat hay has about 9% crude protein. Oat hay features more vitamin A than other hays.
Barley hay is another horse hay option containing about 9% crude protein. This hay rates about the same as timothy hay when it comes to nutrients.
