Why should you use BOVIKALC?

Texas dairy producer John Kisst shares how using BOVIKALC helps prevent hypocalcemia from invading his herd.

The Trouble with I.V. Calcium

Just before and right after calving, a cow may not have all the calcium available she needs to stay healthy.

Reading Calcium Product Labels

When it comes to calcium supplements, the general consensus is that oral calcium is the best way to supplement calcium after calving.

Product Description

BOVIKALC oral calcium supplement is a unique bolus formulation that provides fast and extended support of blood calcium levels in freshening dairy cows.

  • Provides both quick and sustained calcium supplementation that supports blood serum calcium levels at a time when calcium is in great demand
  • A specially formulated and designed bolus helps provide a safe administration and better calcium availability
  • Easy to administer

Features & Benefits 
The BOVIKALC bolus will disintegrate quickly in the rumen. The calcium chloride is available immediately, while the calcium sulfate will provide sustained release of calcium.

Dosage Information
Give one bolus of BOVIKALC prior to or immediately after, calving and a second bolus twelve hours later.

Safety Information

  • BOVIKALC should not be used for initial treatment of milk fever.
  • Do not use BOVIKALC for cows lying down or showing signs of milk fever.
  • Do not use excessive force when giving the bolus to the cow.
  • Read and follow all label directions.

BOVIKALC provides calcium when cows need it most.

BOVIKALC helps fresh cows maintain healthy calcium levels for maximum milk production. Immediately after calving, cows must adjust to the high levels of calcium loss through milk and colostrum, with the lowest calcium levels occurring in older cows about 12 to 24 hours after calving.1,2

BOVIKALC offers fresh cows essential calcium in two ways.

BOVIKALC contains two anionic calcium sources for optimal absorption:

  • Calcium chloride is available immediately.
  • Calcium sulfate provides sustained release of calcium during the post-calving period.

Two BOVIKALC boluses can provide enough calcium to keep cows above subclinical hypocalcemia levels.

Administering an oral calcium supplement to cows at calving and again 12 hours later as directed can provide much-needed supplemental calcium when blood calcium levels are at their lowest.1

BOVIKALC is safe and easy to administer with its no-mess, fat-coated bolus.

The unique bolus dissolves completely within 30 minutes after arriving in the rumen, for quick utilization. The fat coating is also gentle on the throat, making administration simple for workers and safe for cows.

Herds with an anionic salt program can also benefit from adding BOVIKALC.

Anionic salts can reduce cases of subclinical hypocalcemia, but may not eliminate it. Research indicates that herds with an excellent anionic-salts program may see a benefit to supplementing their fresh cows with the oral calcium supplement BOVIKALC1 to further reduce subclinical hypocalcemia.
