White line separation?

[mynutmeg]

My mare seems to be getting some seperation at the white line - is there something I can do to help with this?
Diet wise she's turned out 24/7 but on a pretty bare paddock.
She gets a scoop of Top Spec Lite Chaff (no mollasses etc, just chopped straw, grass and alfalfa) and 2 cups of Top Spec Stud Balancer. She's currently feeding an 11 week old foal. Balancer wise the recommended amount is something like 4-5 cups but she was starting to put weight on so I scaled it back.

She's comforatabel and completely sound but I want her to stay that way!
Any suggestions or is this not something I need to worry about?
Other than this her feet are in decent nick although there's a bit of flare on her fronts

The TopSpec stud balancer is not particularly hoof-friendly, I'm afraid. Stud balancers in general will not provide sufficient levels of those minerals most often found to be deficient in UK grazing (copper, zinc and magnesium especially). As she's out 24/7, you could have a grazing analysis done and feed a bespoke supplement. Alternatively, you could feed a balancer such as one of the Forage Plus balancers, which are true forage balancers, in that they are formulated on the basis of the average mineral profile of UK grazing, as revealed by scientific analysis. Commercial balancers are 'balanced' only to the NRC guidelines, and assume that all grazing and forage is a perfectly balanced baseline, which of course they aren't. I'd probably chose the performance balancer for a lactating mare.

Formula for feet, if you can afford a big bag, is approx £76 and will last a long time, approx 4 months + depending on size of horse/pony
