Pregnancy Toxemia (Ketosis) in ewes
Pregnancy toxemia in ewes is a disease affecting sheep during late gestation, characterized by feed refusal and neurologic dysfunction progressing to recumbency and death. It is seen more often in older ewes and those carrying multiple fetuses. Pregnancy toxemia is almost never observed in replacement ewe-lambs or yearlings lambing for the first time.(2)
Pregnancy toxemia is a metabolic disorder caused by low glucose concentrations in the blood and excessive breakdown of body fat to compensate. “Ketones” are the toxic by-product produced during this rapid breakdown of fat, and it is possible to test for their presence in the ewe’s urine.(2)
