I used Gro N Win for years, but am trying something different. None of my vets have much of an opinion on feeding minis, so I've done a lot of reading/listening. I've always loved the idea behind a ration balancer.
I switched my mares to Contender before they foaled because I didn't want foals getting Gro N Win--too much for them. They shouldn't start it until age 6 months. My lactating mares and foals are on Contender. One mare has lost her topline a bit--but I'll see how she's doing once her foal is weaned, which can be anytime. The other mare looks like she's ready to foal any time, again.
Another forum member who is a good friend of mine had her vet tell her to get her chubby gelding OFF the ration balancer because of the amount of protein. I know, I know...the protein balances out with the grass hay they eat. Remember, I LIKE Gro N Win and the concept behind it. But, I did switch to Lite Balance for awhile just to see if it made a difference in my minis keeping a more appropriate weight--as in lighter.
So far, I like what I see. Well--the minis on it haven't turned into lethargic skeletons
, they seem about the same--maybe look more fit. I see no reason to switch them back to Gro N Win--and the price tag on the Lite Balance is oh so sweet!
They get just a bit more than a ration balancer... half a cup vs. a third twice a day--which is under the recommended amount. I will adjust as I see it's needed.
I truly don't think my minis need anything other than hay and a Flinestone (kidding! You know what I mean!), but I
need to give them more to feel I'm doing my best for them.
I did try Sunshine Plus when I couldn't get Gro N Win for a few months--and I did not like how my minis looked on that. There was a noticeable difference--lack of shine, etc.
