Hypocalcaemia is caused by the animal being unable to mobilise calcium from the bone quickly enough to maintain normal blood calcium levels, or when compounds (known as oxalates) bind up the calcium in the blood. Ewes in their last six weeks of pregnancy and in the first month of lactation are most at risk as during this time the ewe is providing calcium for lamb bone development and milk production. Older ewes are more susceptible to hypocalcaemia.
