Am currently expecting my pony to float off and pop any minute! He got rather too large for his height over the summer so I've put him on a diet - a small handful of mix twice a day with a vitamin supplement, ad lib hay at night and he's out during the day. I reckoned he needed to lose 20-30 kg before spring and I'm now horrified 'cos I'm having to lengthen the surcingles on his rugs! He's lunged 4 times a week for about 15 mins each time (and usually spends most of that in gallop as slow is so boring). I've found a nice big hill and keep pointing him up that to try and lose some of the blubber, but still the little darling's waistline expands. I've tried to get feed with less value in than hay (eg oat straw), but I can't get any. I need the equine version of celery. Any ideas before I need a bigger stable door?
