A new Focus on Forage fact sheet, entitled “Grass Forages and Magnesium Status of Dairy Cattle,” is available at the University of Wisconsin – Extension Team Forage web site.
The two-page fact sheet highlights risk potentials between forage grass production, feeding and hypomagnesaemia (low blood magnesium) in dairy cattle. It also provides preventive steps that you can take when feeding a high percentage of forage grasses to transition and lactating cows, as well as basic forage production practices that can help minimize low plant magnesium.
“Hypomagnesaemia is possible in dairy cows when feeding significant amounts of ensiled, baled or grazed grass forage,” say authors Pat Hoffman, extension dairy scientist, and John Peters, director of the UW Soil and Forage Testing Labs. “Dietary magnesium status also plays a key role with milk fever in dairy cows at the time of calving. In most cases hypomagnesaemia is not a major problem in dairy cattle but certain agronomic grass forage production practices can create a ‘perfect storm’ increasing the risk of acute health problems in dairy cows associated with dietary magnesium status.”
