Problems of the postparturient ewe

THE run up to lambing time is always fraught as ewes try to balance and partition nutrients and maintain the condition and growth of their lambs in utero, while developing mammary condition and starting to produce colostrum. But this period is only the start of the ewes' problems. The majority of ewe losses occur at this time, with an average annual loss of 5 per cent rising to 10 per cent in some situations, which can seriously affect farmers economically. This article discusses the problems experienced by ewes from parturition onwards, giving details of some specific diseases, and suggests treatments and possible measures to prevent losses.
