Hi, interested to see how much hay you would feed a hairy 14.2 gypsy pony over night in kgs. She weighs about 600kg and is overweight. Turned out 8am to 8pm. Thanks
Can you reduce her turnout hours? That's very heavy. It depends what the grazing's like but I'd be inclined to give her no more than 2kg overnight, and it would be soaked.
A horse should never have less than 1% dry matter forage unless under very strict veterinary controls. Starving her won't help you will just kill her metabolism and also cause ulcers and behavioural problems.
I have a 15.1hh cob and about 4 years ago she weighed 700kgs (on vet weighbridge) she is now 550kgs.
You need to remove sugars and starches from the diet and feed plenty of fibre, bits mins etc. Also reducing turnout is not going to help as you are making the horse immobile and this again adversely affects their metabolism. You need to feed a very lo cat chaff, top chop zero, graze on gold blend etc and a good low cap balancer or even better a really good vit and min supplement, rather than a balancer, as a balancer is just extra calories. Pink mash is great as a filler as it is less than 0.5% starch sugar and all fibre. Hay should be soaked and fed in a double net, about half a kilo for every stabled hour
