Toxemia was induced in 13 of 20 pregnant ewes by the stress of a change in environment and food deprivation late in pregnancy. weak but she’s coming along.”, “We were definitely pretty concerned about her the last several days leading up to It is also called twin lamb disease, lambing or kidding sickness or lambing paralysis. Pregnancy toxemia in cows is similar to the condition in small ruminants and is the result of fetal carbohydrate or energy demand exceeding maternal supply during the last trimester of pregnancy. Pregnancy toxemia in sheep and goats has also been called ketosis, lambing/kidding sickness, pregnancy disease and twin-lamb/ kid disease. her having the lambs,” said Williams.

University College of Veterinary Medicine’s Veterinary Medical Hospital. The primary predisposing cause of pregnancy toxemia is inadequate nutrition during late gestation, usually because of insufficient energy density of the ration and decreased rumen capacity as a result of fetal growth. There are two factors involved in the development of hypoglycemia. If ewes are exclusively grass-fed, special emphasis should be placed on feeding high quality roughage to ewes in late pregnancy. There are two possible measures to treat the disease: Treatment must be frequent and vigorous during the early stages to be successful as the pathological changes associated with hypoglycemic encephalopathy become irreversible during the later stages of pregnancy toxemia.

Cattle that have lost weight but are still eating may be managed by feeding concentrate or propylene glycol (0.5–1 g/kg/day for up to 5 days). The resulting ketone bodies can be used as a source of energy, but excess will result in hyperketonemia, which in the toxaemic ewe is accompanied by metabolic acidosis.
