Description
ausmag® AL4 is a reactive calcined magnesium oxide, produced under closely controlled conditions. Causmag® AL4 is a finely divided white powder with consistent particle size and high reactivity, for use in agriculture and animal health.
Uses
Causmag® AL4 is used to supplement sheep and cattle diets where Magnesium levels may be low. Magnesium has a role in metabolism, formation of bone and teeth as well as maintenance of nervous function. It is used as an addition to stock feeds, medicated mineral stock blocks and as an oral drench for dairy cattle.
