Hypomagnesemia, also referred to as lactation tetany, is a life threatening condition of low blood magnesium concentration, which is a common problem for lactating does on spring pasture. Growing kids on milk replacer is a similar condition which is referred to as milk tetany.
A distinguishing characteristic between lactation tetany (low blood magnesium levels) and milk fever (low blood calcium levels) is that goats with lactation tetany will develop muscle spasms. Also, lactation tetany usually occurs during early lactation, as opposed to milk fever which generally occurs during peak lactation.
