To date most RDE&A has focused on improving ewe nutrition during pregnancy and management during lambing and weaning. There remains an untapped opportunity to improve lamb survival outcomes though more rigorous ewe assessment and selection before joining. As such, this project will develop a series of producer ewe assessment tools to aid the selection process prior to joining, this will include selection and management criteria for ewe lambs through to older ewes and will accommodate factors that hamper ewe capacity to rear a lamb such as udder health and lameness.
