I will be bringing home my new weanling filly next month, and she has a lot of potential to be a good one. I'm wanting to get her started on the best feed program possible, and am wondering what everyone has liked the best with their foals.

I'm currently feeding my 8yo mare grass and alfalfa hay, 1.5lbs of Renew Gold, and MagRestore. I'm not sure if the Renew Gold is best for growing babies, though, so I want to find the best thing for her!

Thanks for your help!

Careful with the alfalfa. Read the new research. It shows the alfalfa may be causing bones to not form correctly in growing foals. Some of the problems are not showing up until the horses are started. Just read it for yourself and make an informed decision. 

I am feeding Purina Mare and Foal Omilen 300 at their recommendation. They are on grass pasture and grass round bales. 

This is my first foal in 35 years. 

I am almost 67 and I don't think I am going to be young enough or physically in good enough shape in 2 years from now to start a 2 year old. Someone is going to get a very well bred barrel prospect 

You will be fine with Renew Gold at 1/2 pound to 3/4 pound per day should you decide to go that way.  Mixed hay would be fine. Most developmental issues with uneven bone to soft tissue growth, where alfalfa is concerned, are related to feeding straight very high protein dairy quality alfalfa in the 20%+ protein range. A mix of alfalfa and grass is generally considered very safe for growing horses. They do need quality protein for tissue growth, and some straight grass hays do not provide enough. Adding a soy based ration balancer to make this up may cause more problems that it solves. Some horses are very sensitive to Soy in the diet. Some alfalfa in the program can actually be safer for development overall. For the entire diet, you want a cal/phos balanced diet with 15% to 16% quality protein when everything is considered. The calcium and protein contribution provided by some alfalfa in a mostly grass hay diet can be a positive influence in proper normal growth.

Thank you WinWillows for the knowledge that you bring to the forum. 

I enjoy reading the nutrition information that you bring here. Even though I am mostly a retired stock cow person.
