Bovikalc Oral Calcium Supplement for Cows

Delivers 42g of available calcium in each bolus, calcium chloride (fast release) and calcium sulphate (slow release). Each bolus also has an acidifying effect, much like a DCAD diet has, which helps the cow to mobilise her own calcium reserves. The bolus dissolves in the rumen within 20-30 minutes and helps to raise blood calcium levels over a prolonged period of time.

When you decide to give calcium boluses to your cows, you have 2 options: targeting the cows that need it the most or treating everyone.

The first option is to target the cows most likely to benefit from a calcium supplement. A large field study using two Bovikalc® boluses given 12 hours apart (one administered at calving and the second one administered 12 hours later) has shown that lame cows and high producing cows have the best response to oral calcium. This group gives the best return on investment. However, this optimal economic solution requires more management and effort to identify the cows.

The second option is to supplement every cow in her second lactation and up. In many herds, this second option will be easier to implement and it is still economically sound.
