These conditions are imbalances of glucose in the systems of sheep (twin lamb disease/pregnancy toxaemia) and cows (ketosis/acetonemia). Typically, they occur just before and/or shortly after calving/lambing time. Treating them involves the administration of propylene glycol, a precursor for glucose production, which is found in Chanatol. Treating orally with glucose will not work as it will be metabolised by the microbes in the rumen.
