Lammerensterfte, leverbot en ureum bij melkschapen

J.C. Verkaik, G. Smolders

Research output: Book/ReportReportProfessional


The monitored lamb mortality at organic dairy sheep farms is relativly high with big differences. Mortality over 10% is caused by poor management and infectious abortions. Short term improvements needs a structured approach. Treatment of the dairy sheep is limited to the dry period. Avoiding infection by housing ewes in early lactation appears effective. Liver fluke is well predictable on the prognosis and the fluke and grazing history. The time between infection intake and appearance in blood or dung makes these researches risky. Urea appears dependable upon the amount of protein fed. Protein wastage reduces when more energy is fed.
