Pregnancy Disease - A Flock Perspective
نویسنده
چکیده
Pregnancy disease (pregnancy toxemia, twin lamb disease, lambing sickness, lambing paralysis or lambing ketosis) typically affects ewes during the last 2 to 4 weeks of pregnancy and is a common cause of ewe and lamb loss in Michigan flocks. Overconditioned or thin ewes, usually pregnant with multiple fetuses, are most commonly affected and clinical cases are generally limited to older ewes during their second or subsequent pregnancies. Pregnancy disease is rare in both bred ewe lambs or yearlings bred for their first pregnancy.
