You need to get the lambs weaned or the ewes won't start cycling early enough. As a guide, we will be weaning next week and the tups go in in mid October. Keep them a bit tight for a week of two to help them dry off and then just let them have enough grass to keep them ticking over. This is assuming that your ewes are lean and fit, having just reared lambs. If they are fat, it will pay you to keep them on tight grazing for a bit longer. Put them on to better grazing a couple of weeks before the tup goes in - if you use teaser move them to good grass at the same time as putting in the teaser. The key is to have the ewes fit and in rising body condition when they are tupped. Make sure they have good grazing for about six weeks as pregnancies can be lost early on if there is insufficient grass.
