my boy has epsm and has to have alot of oil, I found he wouldn't touch veg oil and when I mixed his feeds by hand I got a vile taste in my mouth. He is much better with the sunflower oil (and so I am -LOL)
buy equine complete, gives vits, minerals and has my horse looking AMAZING.
(oo...think I may have posted about it too much... but it is really good for my boy!)
Soya form the supermarket, I pick it up at tescos under a pound! So dirt cheap! It is Fricking amazing for their coat, manes/tails and hoovies also better then sunflower and veg as great for top line etc. Turned mine out from summer and could really see what not having the soya did so she was straight back on to it!!
