Helpful Tips:

If you're using an anionic salt program in your herd, your cattle can benefit from Bovikalc. Anionic salt can cause a reduction in subclinical hypocalcemia cases, but it might not eradicate it completely. Research has shown that herds with an efficient anionic salt program can benefit from supplementing fresh cows with this product because it further reduces cases of subclinical hypocalcemia.


Feeding Directions:

Boluses are given to the cow using a special Bovikalc bolus applicator sold separately. Allivet product #50988 Bovikalc Plastic Balling Gun
