Feeding my colt foal

Question
Hello.
I am British and I have a 6 month colt foal and I live in a rural part of Turkey where you cannot purchase any horse items like in the western world (ie: complete feeds, tack etc. I even had to ask a friend from the UK to bring over a headcollar!) Anyway, we found a good vet here who wormed him and gave him his shots (his older brother is a horse vet who lives 3 hours away and sent over the medication).
Foodwise: Out here you can only purchase oats/barley/protein pellets/cottonseed meal/chaff by the kilo. So what I did to get him onto some of that was to get grapevine leaves (which he loves)and mix it with the soaked cottonmeal. He is now on a big sized cake bowl of chaff mixed with cottonmeal, some oats, barley and pellets twice a day plus all day chaff. Is this enough? or should I be giving him more? The vet didnt really help with food amounts because he wasnt an equine vet.
Our foal is a Turkish breed, has influence of Kabardin Im sure and so is an easy keeper, very friendly and willing to please. You can see his pictures here: http://www.flickr.com/photos/26404505@N07/2667929696/

Please help with feed amounts - I am concerned if he is getting enough. Thanks.

Hi Sarah!

Yikes!  You have quite a challenge here!  I could go into how to calculate TDN (total digestible nutrients) and have you crunching numbers for the next week, but I just don't think it is necessary.  Really a conservative diet for a growing horse is really best.  Make sure you have a balanced ration that incudes copper and selenium.  Having a good multivitamin sent from the UK would be a wise choice.  A diet that is 12% protein, low in soluble sugars, and high in fiber should give your colt what he needs to be healthy and successful.  

If you can step back and take a good look at your horse, you should see good weight, quality hair coat and feet, a bright eye and good energy, you know you are on the right path nutritionally.  If your colt is looking un-thrifty, dull coat, cracking in the hooves, mentally dull changes are needed.  Your horse really will tell you what he needs.  I would keep a weight tape handy to mark his progress and take a photo every few weeks.  Add this information to his health record and compare the photos.  This will give you a very clear idea of how your horse is coming along and maybe help you see what your might be missing.  

Thank you for the link to the photos!  I'll check them out.  What a wonderful adventure for you and what a wonderful breed!  Keep me posted.
