Thanks for the reply, as far as her diet goes when I first got her she was just on alfalfa no gain or supplements. She was a little under weight too but since having her she has lost tons of weight because my other mares will chase her away from her food. So now I've separated her and put her on senior grain, a supplement witch has oats in it and beet pulp but as far as I can tell its not really made a difference on her hotness and energy level. I want to take her off the gain but she is a pretty hard keeper and I don't know if beet pulp and hay will be enough.
You are right, more than likely the hay and beet pulp wonít be enough. You can still look at grain free supplements/feeds if you want to take her off traditional grains.
I did use Nutrena Safechoice as a good grain free feed while between two different RBís (my feed store had an availability issue and I had to use something while the problem got worked out.)
Or, you can use a ration balancer along with the beet pulp. RB's contain a lot of micronutrients as well, so most horse don't miss out by taking the ďgrainsĒ portion of a diet away from them. Some come in higher fat formulas too.
RB's can be fed alone or as part of a diet containing other feed stuff and many use it to boost nutrients, help with weight gain, and to help hard keepers.
My horse gets an RB only for his ďfeedĒ and around one cup a day (yes, a baker's measuring cup) because he is an easy keeper.
But RBs can be fed at higher amounts for horses who need the increased intake.
My guess is (and admittedly, it is just a guess) an RB will help your girl as well as fill in any nutritional gaps she may have.
There have been some good discussions here about RB here and if you do a search in the search box, they should come up. Also, you could try looking at the websites for your preferred feed brand and seeing what they have for a ration balancer.
Iím not trying to push RBís on you, honestly
, I just donít want you to think you donít have other feed options if you want to try something different for your girl.
