Haven't checked in to this thread for a while, thought I'd make a quick couple of comments more
I'd like for him to be able to have grain for nutritional purposes, but he just gets so FAT!
Well I've got what for once on this forum for assuming 'grain' meant grain, so will first clarify what I'm talking about is indeed grain, grain based feeds, or high sugar/starch feeds....
I know it's been said before, but needs emphasising... If people really want to feed grain to their horses for whatever reason, please do your homework first **& look at more recent research, not just the traditional stuff**. Despite it being a traditional, still common feed, it is NOT generally a good feed for horses. If ingredients such as this are to be fed, please bother to learn how they effect the horse & how you can minimise the problems it causes. Such as feeding tiny amounts over *at least* a few feeds daily, rather than feeding it only twice or less daily &/or large feeds. Such as learning how it can cause laminitis, Cushings, IR, colic, weightloss....
Now back to OP's above comment - definitely if he's already fat you don't want to feed anything like grain, but yes, they do still need nutritional supps. You can get them 'straight' or in 'ration balancer' pellets, which are often grain based, but you may consider this, depending on the horse, with a type you only have to feed a very tiny amount of.
a few weeks to look into your recommend supplements and figure out which one will be the best for her. I will be taking money into consideration also when choosing a supplement....not that I would rule out a great supplement because of that, but if I can find a really good one for cheaper,
Again, I know I sound like an ad for them
, but I can't recommend highly enough the services & program of Feedxl.com to take the confusion & trial & error out of the question of balancing nutrition. They also have some very cheap sub options, that make using their services potentially only light pocket money, (but they've actually SAVED me money anyway) unless you want to sign up for longer/more horses, etc. I'm sure there are other services such as this out there, if that particular one doesn't suit too.
Re price of supps, yes, don't we all want the cheapest option where possible?? But after analysis of a heap of different supps.... meaning proper analysis, not just going off the packaging, which tends not to be so accurate & invariably paints a 'rosier picture'..... I have come to the conclusion you definitely get what you pay for. BUT I have also found that the more expensive *per package* aren't necessarily that costly. For eg. the feed store guy asked me to sit down when I asked him to order a 'ration balancer' supp called KER Gold Pellet... then told me it was $170 per 20kg bag!
I thanked him & went away without ordering
After further analysis, I went back to him & told him to sit down... & ordered some!
Despite the 'recommended dose' on the bag, thanks to feedxl.com I worked out my horses would need only about half that much - whopping 60g per day; a single handful! - and it amounted to only $1.20 a day for all 3 of them! That is vastly cheaper - & vastly less quantity & calories for my fatties - than anything 'cheaper' would be, not to mention giving them a much better balance of nutrients in one product than any other combination I'd looked at.
Anyway, suppose that's further info to overload your brain! Hopefully it's of some more help to you!
