I have an hypp horse that eats oats and grass hay, I was wondering if you can tell me what the best supplement would be to balance his diet. Right now I feed him Opt-E-Horse for the vitamins and minerals, he also gets MSM, synovi msm, and foundation for his feet.

Where are you from? ct

Re: hypp

Hello Sharon,
You’re on the right track with feeding oats. However, many grass hays can be high in potassium. The potassium levels in different grasses can vary dramatically. Oat hay would be a good choice, but Timothy or Bermuda or orchard grass are much higher. Here is a chart that may assist you:

Potassium Levels of hay (midbloom)*
Pangolagrass hay 1.27
Ryegrass hay 1.34
Oat hay 1.35
Bluegrass hay 1.40
Alfalfa hay 1.42
Coastal Bermudagrass 1.58
Red Clover hay 1.60
Timothy hay 1.61
Brome hay 1.74
Birdsfoot Trefoil hay 1.74
Kentucky Fescue hay 2.17
Orchardgrass hay 2.59

You can also add beet pulp (unsweetened) to the diet for additional energy. This will allow you to feed a smaller portion of oats.

I would not feed Opt-E-Horse. It contains potassium. An antioxidant preparation, such as Vita-Key Antioxidant Concentrate will help your horse deal with the physical stress by adding additional amounts of vitamin E, C, and other essential nutrients. MSM is fine.

I hope this is helpful.

All the best,

Dr. Getty
