Welcome to my forum.
Here you will find more than 6 years of questions and my answers. It is searchable and offers a great deal of information.
Currently, I am discontinuing new questions. This may change in the future, but in the meantime, please know that It has been a true pleasure serving you.
Take a look at my Nutrition Library and Tips of the Month for a variety of answers on selected topics. Be sure to sign up for my monthly e-newsletter, Forage for Thought.
I also have a growing number of recordings on "Teleseminars on Nutrition Topics that Concern You" as well as the new, Spotlight on Equine Nutrition Series -- printed versions of favorite teleseminars.

Hello Erika,
Glanzen Complete is flaxseed meal based, and an excellent source of fat that is high in omega 3 fatty acids. But if additional calories are needed for weight gain, stabilized rice bran that has a small amount of calcium added (to correct for high phosphorus levels naturally found in bran) would be a good choice. You can safely feed up to one pound per day.
For weight gain, also keep in mind that the high gut microbial population needs to be healthy. These microbes are responsible for digesting fiber (from hay and pasture). So, if their numbers are inadequate, your horse will not get calories from forage. A good probiotic combined with a prebiotic, is worth considering. I like SynBiotic EQ, since it also protects immune function.
All the best,
Dr. Getty
