Guidelines on the Disease during the Conversion Period

• If hypomagnesaemia in cows is a problem on the farm at the time of conversion, the reduction in the incidence of hypomagnesaemia should be part of the overall health plan.
• On problem farms, a strategy should be worked out with the veterinarian to control and prevent hypomagnesaemia. (For example, management strategies, strategic use of in-feed minerals, mineral licks, etc.)
• Measures should be taken to improve the situation in the long term and to reduce dependency on conventional treatments. For example, the composition of the sward could be changed in such a way that the mineral status is improved (e.g. inclusion of legumes).
