Bio-Vet Inc. has released a new formulation of QuadriCal calcium boluses.

New QuadriCal AC is an all-calcium bolus, in which four types of calcium — calcium chloride, calcium propionate, calcium lactate and calcium sulfate — provide for rapid, intermediate and sustained calcium release. Each three-bolus feeding of QuadriCal AC contains a minimum of 54 g of total calcium, Bio-Vet said.

Studies have shown more than 40% percent of all cows and more than 50% of second-plus lactation cows in the U.S. have low blood calcium around calving time. Research indicates that a minimum of 50 g of calcium is needed to significantly raise blood calcium levels.*

QuadriCal AC is the newest addition to Bio-Vet's line of calcium products that includes QuadriCal, QuadriCal MINI and ‘O’ QuadriCal MINI boluses and Cal-D Cap calcium capsules.

New QuadriCal AC is available in an 80-count box of individually packaged feedings.
