Abstract

Grass tetany (hypomagnesemia) frequently occurs from March through
June in cattle grazing crested wheatgrass in western United States. High levels of trans-aconitate
and/or citrate, K, K/(Ca + Mg) ratios and low Mg in the grass are implicated
in the etiology of the disease. In the moist 1967 season, during periods of "flush"
growth following warming trends, trans-aconitate and K increased while Ca and Mg
decreased in crested wheatgrass. These characteristics may explain the incidence of
grass tetany during periods of "flush" growth. During the dry 1968 season, these
trends were not observed. Growth chamber studies confirmed some of the reasons for
changes in crested wheatgrass composition observed in 1967 and 1968.
