Magnesium Oxide For Animal Feed and Health
Feb 06, 2019

Magnesium supplementation is needed to prevent hypomagnesaemia (grass tetany-staggers) and milk fever (when calcium is also low) in beef (and dairy) cows from calving to peak milk production.

Magnesium is needed to activate calcium absorption-resorption and so the two are neatly intertwined. Historically magnesium  supplementation for beef cows has been limited to four options:

Pasture dusting with magnesium oxide (causmag) or supplying causmag to fed hay or silage pre- and post-calving are methods that can work well.
