Hello, I have a 19 month old Andalusian that is already 15.2 hands. I am feeding mostly orchard grass and about 1/3 of his diet is a grass alfalfa mix. No grain. His weight is good. I feed him Horse Guard. He seems gassier than my other horses. His stool is normal, he has had a panacur powerpack (was gassy before that. What are common causes of gas in horses? I have fed all of my horses Horse Guard for over 10 yrs. I live outside Portland, OR. Thanks

Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:

It is perfectly normal for horses to be very gassy. As they ferment forage in their hindgut gas is produced as a by-product. So, it sounds if your Andalusian has a very efficient digestive tract. You have nothing to worry about. If he’s in good body condition, I would keep him on his current feed regime.
