Pregnancy toxaemia is a metabolic disorder where the body’s energy requirements are not being met by feed intake, resulting in the ewe breaking down her own body reserves (fat and muscle) to meet the shortfall in energy. When fat is used as an energy source, ketones are produced. If the rate at which the ewe breaks down her body reserves is too rapid, ketones from the breakdown process accumulate and pregnancy toxaemia occurs.
