Pregnancy disease is an upset or interference in the metabolism cycle of carbohydrates; it is not related in any way to the amount of exercise the ewe gets. In converting fatty acids and particularly body fat to glucose, ketones accumulate in the bloodstream and blood glucose levels decline. The ketones are very toxic to the ewe, resulting in death within two–five days.
