Flock visits with LambPlus breeders are currently suspended due to Covid 19 restrictions, generally ewe mature weights are taken by Sheep Ireland technicians at this time of year. LambPlus breeders are encouraged to take ewe mature weights themselves as they are very important in contributing to genetic evaluations, especially now where some lambs are approaching wean (100 day) weights . These can be entered very simply via the LambPlus App! The best time to carry out the recording of ewe mature weights is while lambs are being drafted through the race capturing their wean weights, weighing both ewes and lambs together makes this simpler for breeders. Using the LambPlus App is the simplest way of recording ewes mature weight as well as wean weights , simply go to ‘Weighing’ in your App and record your ewe mature weights as well as the lamb weights as they are being drafted together through the race. Ewe mature weights contribute to maternal production and efficiency traits and also contributes to the accuracy of the replacement index in genetic evaluations.
