I moved her from the States to the UK about three years ago and since she has been here, she has been much harder to keep. Again the main difference is that at most of the barns we were at in the US, she was kept in dry lots on hay and grains and sweet feeds. Could there be something in the soil here she is not getting which we need to supplement somehow? At her current barn she is getting hours more turnout than she got at other places.
I'm tempted to switch her (slowly now of course) back to a sweet feed.
She is on a regular worming schedule and was tested when she moved to the new barn. Also had blood tests in August/September because she was being stressed at the barn she was at then. She checked out healthy (turned out what she really wanted was a pasture buddy).
We just upped the conditioning cubes today and if there is no improvement in a week or two, I'm going to talk to a vet and/or an equine nutritionist. In the meantime, I'd thought I'd post here and get your thoughts.
