Ask the Nutritionist: Dr. Getty's Forum for Equine Nutrition
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.
And finally, look for my articles in a variety of local publications and online newsletters, as well as the Horse Journal, where I am the Contributing Nutrition Editor.
All the best,
Dr. Getty
Hi Judy,
Yes, this hay is fine at 12.9% NSC. Your calcium, phosphorus, and magnesium are in the proper proportion. But, more magnesium is needed. I suggest Quiessence -- 1 scoop per 500 lbs of body weight.
A comprehensive vitamin/mineral supplement is worth considering. The one I like best in your situation is Glanzen Complete. This can be fed in addition to Quiessence since Quiessence provides magnesium that is not found in the Glanzen supplement. It is a custom product made by Horsetech, so it won't be in your feedstores, but shipping is free. Horsetech also makes a nice supplement that may be in your feedstore (and soon to be on my website) called High Point.
I'm glad you enjoyed the recorded TeleClass. For folks who are not familiar with this, I have a few live recorded events available for free on my website -- go to www.GettyEquineNutrition.com and click on Listen to Dr. Getty.
All the best,
Dr. Getty
