Im considering changing good coastal hay to a good coastal/bluestem mix hay. I have a 10 month old and an 11 yr old that both get safe choice grain and free choice coastal. They look great , but are going through hay like crazy and I thought if I get this mix I could save a little money and slow them down. My concern is that I have heard of horses getting "hay bellies" from lower nutritional forage. Has anyone experienced the hay belly from bluestem hay? Im taking a sample of the hay to the Texas Dept of Agriculture to get a nutrition count on it tomorrow, so Im sure Ill get some good info. Thanks for any experiences with a "hay belly"!
