Into the 458kg band this morning and I can definitely feel some ribs if I prod hard enough. I think the 464kg band is going to be the one we try not to exceed over the summer - quite a challenge when he topped out at over 511kg last year!
The sugars are definitely coming through strongly in the grass now; he's got a couple of scurfy lumps in the usual places and he's grouchy, though that might also be to do with the amount he's moulting at the moment. The problem is that the sugar makes his skin sensitive and the moulting makes him itchy, so grooming him is a bit of a lottery - I either get a blissed out horse with a wobbly lower lip or one who whips round with his ears back and his teeth bared. He's much better than last year though, when he was on a sugary feed as well.
