it all a learning curve
i start to wean at 4 months as i am not in a rush to push them and i sell direct to the customer, by then most have weaned , or started to and can noticably see that the udders are slackening off, my averages are 39.5kg this year but they havent had creep just grass and Milk.
i take the tups off and leave mums with the Gimmers and so that they slowly wean and i have never had a case of Mastitus, i will give the tups a little bit of grub for the next week as they can go backwards a little bit with the stress of weaning. in fact this year they wasnt bothered
i have one ewe that has weaned, no udder and pretty much back in condition, she's certainly a keeper,
this works for me and my set up it maynot wrk for everyone
