Hi Barbara & Hoogie
Thanks for the info, you have confirmed my worries that it could be a bit much on it's own......as this farmer grows it himself (ie it's not a branded make or anything) I asked him if he had had any nutritional analysis done on it and he said 'oh no, I just grow the stuff' ! It's a shame he didn't it get it looked at, maybe it costs too much.
Both of the horses in question are on fairly high protein diets, my weanling is on Foal Mix which is 15.9% protein, and my colt is on Mare & Youngstock Mix which is 14% protein, both manufactured by Dodson & Horrell. With this they also get a big handful of Readigrass. I used to feed Dengie Alfa-A instead, but I was getting through so much of it that I changed to Readigrass just to add a bit of roughage to their feeds. I have plenty of grass but don't think it's that great feed value wise though as we had an abundance of thistles all summer which took over a lot!
Anyway, I have a couple of bales of it to try and have been mixing it half and half with their normal haylage, it's really lovely stuff and they love it too. Might be hassle though having to mix the two types all the time though - might leave it for the winter and then just feed it to my filly when it gets nearer to show time for the conditioning value? Does anyone feed it in pure form to their show yearlings?
