An oral mineral supplement to be given to dairy cows at drying off. Can help support the natural decrease in milk production after cessation of milking. Reduced milk production helps reduce milk congestion in the udder. Contains anionic salts including ammonium chloride, calcium chloride and calcium sulphate. Following oral administration, the bolus dissolves into the rumen within 30 minutes and the anionic salts are released and then absorbed. Two boluses to be given at drying off or 12 hours before drying off.
