Why are Ewe Mature Weights Important? Record Them at Weaning of Their Lambs!

During flock visits with LambPlus breeders Sheep Ireland record ewe mature weights, while the Covid-19 restrictions are still in place flock visits are currently still postponed. Nevertheless breeders should still be recording ewe mature weights as they very important in contributing to genetic evaluations. LambPlus breeders are encouraged to take ewe mature weights and these can be entered via the user friendly inspection screen on Sheep Ireland’s App and website. The ideal time to record ewe mature weights are when lambs are being weighed at weaning time (100 day weight) where lambs are between 66 – 120 days old and a pre-mating weight before rams begin serving ewes. Ewe mature weights contribute to maternal production traits and the efficiency of ewes contributes to the accuracy of the replacement index in genetic evaluations.
