Pre-lambing: Ewe Nutrition and Metabolic Diseases Adequate ewe nutrition during the last six weeks of pregnancy, when 75 per cent of foetal growth occurs, is essential to ensure appropriate lamb birthweight. Part 1 The Basics Ewe deaths around lambing time in lowground flocks in the UK are quoted as 5 to 7 per cent with an estimated 70 per cent caused by dystocia (lambing difficulties). Part 2 Lambing Problems This bulletin highlights the various different lambing problems faced at lambing. Part 3 Vaginal and Uterine Prolapse Vaginal prolapse affects approximately 1% of ewes in the last month of pregnancy. It is most common in over-conditioned ewes carrying multiple lambs. Part 4 Ensuring Survival of Newborn Lambs Neonatal lamb deaths average 10-25% in the UK, but 5% is achievable. Good flock records will help you plan in the future. Part 5 Diseases of Newborn Lambs This bulletin highlights the various different diseases of newborm lambs. Part 6 Fostering, Docking and Castration The perinatal lamb mortality rate is unacceptably high in many sheep flocks; as a consequence of such deaths triplet lambs are fostered on to those ewes which have lost a lamb.
