Mine are on wee bit of shreds and a dusting of oats when milked once a day. I then just leave out one milking, so milk one-in-three for a few days and so on... but, do you really need to stop milking completely? They will happily milk once a day on some concentrates until about 8 - 6 weeks before kidding, and it allows you to feed a bit more without worrying about them getting fat. They will dry off completely quite easily in Nov/Dec time, just now there is still quite a bit of good enough grass around...
