Calcium and magnesium deficiencies in pregnant and lactating ewes
Clinical calcium deficiency (hypocalcaemia or milk fever) can result in ewe deaths either during the last six weeks of pregnancy or during the first month after lambing. Symptoms include muscle tremors, being unable to rise and subsequent death. Clinical magnesium deficiency (hypomagnesaemia or grass tetany) can result in ewe deaths, typically when ewes are grazing grass-dominant pastures or cereal crops in winter and early spring. Symptoms include staggering, incoordination and sudden death. Hypocalcaemia and hypomagnesaemia can cause ewe mortalities, and lambs from affected ewes will usually die. Lambing difficulty and complications from birth may also be increased, reducing survival.
