+==Introduction==
-==Description==
+A disease affecting ewes during the last few weeks of gestation. Mainly affects twin or multiple bearing ewes. The condition occurs when the ewe does not receive an adequate energy supply during a time when the rapidly growing foetuses drain carbohydrate stores. This results in a sub-clinical ketosis which can quickly progress to a clinical pregnancy toxaemia. It is a serious condition which can be fatal and most frequently affects lowland flocks.
 Very similar to [[Ketosis of Cattle|ketosis in cows]].

 Can often be diagnosed on history and a clinical exam.
-Differential diagnoses include [[Listeriosis|listeriosis]], [[Lungs Inflammatory - Pathology#Pneumonia - Introduction and Classification|pneumonia]], and hypocalcaemia.
+Differential diagnoses include [[Listeriosis|listeriosis]], pneumonia, and hypocalcaemia.
 ==Clinical Signs==
 Mainly neurological signs are apparent as a result of the hypoglycaemic state of the animal. Ewes are often depressed and not aware of their surrounding, they can adopt an unusual posture which may progress to ataxia or recumbency. Some appear blind and there may be trembling and twitching of the face and ears.
-Ewes often grind their teeth and make chewing movements.  They are also anorexic and may have breathing difficulties and a nasal discharge.

 Some ewes abort which may result in septicaemia.
 ==Laboratory Tests==
-Biochmeistry will often reveal a hypoglycaemia and a hyperkalaemia due to ketoacidosis. Additionally a high ß hydroxybutyrate (BHB) (which is one of the ketone bodies) level will also be evident. BHB is a more reliable measure of disease as not all animals show hypoglycaemia on blood work and some even are hyperglycaemic.

 Treatment of advanced cases of pregnancy toxemia is often unsuccessful.
 Propylene glycol can be given orally that acts as a precursor to glucose. The addition of calciumm, potassium and insulin is also useful.
-Hypoglycaemia can also be treated by administering IV dextrose, follwed by an oral electrolyte solution.

 Severe ketoacidosis can be treated by administering oral potassium chloride (KCl).

 A blood sample should be taken from a number of ewes in late gestation and glucose and BHB levels measured. This will determine if there are any problems in the rest of the flock.

 ==Prevention==
 Ewes should be in a good body score at tupping and should maintain a good body condition score throughout gestation.
-Good body condition can be maintained by good mangement of feeding. Ewes should recieve grain as a carbohydrate source and also a protein source so that the [[Rumen - Anatomy & Physiology|rumen]] microbes can make use of the carbohydrate.
