16.2hh 18 yr old retired idxtb poor do-er, quite fussy with feed, lives out, has ad lib good quality haylage, currently fed alpha a oil, d&h 16+ mix and speedi beet plus joint supplement.
I found D & H 16 plus sent my boy a bit loopy! Also, any form of cereal mix is not good for stiffness, which I guess your boy has if he is having joint supplement?
My now 31 yr old TB is on Allen & Page veteran vitality, fast fibre, Alpha oil, plus instant linseed and a general supplement. His stiffness has eased a great deal since stopping feeding a mix, and my farrier has noticed a HUGE difference when shoeing his hinds in that the horse is finding it MUCH easier.
i would apart from the fact hes decided he doesnt like this any more and spent the best part of 40 minutes snuffling around the bucket and chucking the feed about.
have you tried straights?
Fast Fibre, barley, linseed & sugar beet might be worth a go - my friends horse loves it (shes fussy & a poor doer) & looks great on it.
he used to have barley,sugar beet and aplha a but then decided he didnt like it, swapped to barely rings which he liked,then feed shop stopped stocking them.
My oldie recently moved on to Baileys conditioning cubes, he is very picky and I have tried most things but he loves this feed and now mugs me when I feed him rather than as previously looking at the bowl with suspicion and carefully taking little nibbles then leaving most in the bowl.
