Do you use Calcium Boluses in your Herd?
Administering calcium boluses to fresh cows has become a widely adopted practice to prevent hypocalcemia on U.S. dairy farms.
But are all calcium boluses equally effective? According to a study by a group of Canadian researchers: no.
Verhoef and his team concluded that calcium chloride/calcium sulfate boluses were more effective at generating serum calcium response than boluses containing high amounts of calcium carbonate. They also suggested that administering two boluses together within 12 hours of calving may be more effective than the traditional treatment of giving two boluses 12 hours apart.
