Re: Dengie Alfa-A
I don't know what type of breed your horse is?
A lot of cobby types, and probably others as well will go hyper on pony nuts - I know they're classed as non fizzy, but it all depends, my mare when we first had her started on pony nuts and went crazy, and several people on here have said the same.
The alpha a should be fine, and maybe try something like speedibeet, which is filling with no sugar.
Also a lot of horses lose a bit of condition through winter, but with the spring grass coming through (hopefully !!) soon, you may find she'll pick up anyway.
Nutritionists are great, but every horse is different, and they're not always thnking of a specific horse, just that type in general, which is not always ideal.
Maybe try NAF pink powder as well, as an allround food balancer - but I'd definitely cut out the pony nuts !!
