Do you cull your empty ewe lambs @Tim W ? How long do you give them?
Don't necessarily cull the empty ewe lambs as they will be the smaller trips etc ---gave them 28 days just the same as the ewes .
Ram lambs for the first 14 days this year followed by a raddled chaser ram ----- very few ewes raddled .
I think that out of 758 to lamb this year only 80 (?) are raddled ---this is excepting the Charollais which I AI'd on the first cycle so they had a bit longer with a chaser ram to give them a good chance
The Charollais I have purposely treated mean as I need to get them tougher and more able to cope with the world ---hence their lower scanning rate...(and slightly higher barren/culling rate)
