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
G'day Rachel!
Well, the only way to know if your mare is pregnant is to have her examined by your veterinarian and have an ultrasound performed.
If she is pregnant, you'll want to feed her a nutritious diet that is mainly from good quality grass and/or hay, as much as she wants each day. And, add an overall vitamin/mineral supplement designed for broodmares to some alfalfa pellets each day. Alfalfa is important to provide her with additional amino acids and calcium. Avoid giving her grain such as oats, corn, or barley -- unless you are exercising her regularly -- and even then, only a small amount since too much starch can lead to joint problems in foals.
As she approaches her last three months of pregnancy, her dietary needs will change -- she will need far more calories since she'll be gaining weight rapidly.
Pick up a good foaling manual. I have The Complete Foaling Manual on my website which is the best one out there, in my opinion (and I've seen them all!).
Happy Foaling!
