THE WHOLE HERD APPROACH TO MANAGING HYPOCALCEMIA
Studies show that up to 50% of cows in a modern dairy herd are affected by subclinical hypocalcemia at calving. No clinical signs can be detected but negative effects on health and milk production can be significant.
A recent economic analysis1 suggests that giving Bovikalc® to all cows second lactation or above, around calving can almost always deliver a positive financial return to the farmer. So the hurdle of identifying cows at risk of subclinical hypocalcaemia, can effectively be removed.
Reducing the risk of milk fever, that’s the beauty of Bovikalc®
Bovikalc® delivers an impressive 43g of available calcium in each bolus:
- Calcium chloride (fast release).
- 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 30 minutes and helps to raise blood
calcium levels over a prolonged period of time.
TO BE USED IN DAIRY COWS AT RISK OF DEVELOPING MILK FEVER,
ESPECIALLY IN HIGH YIELDING, OLDER DAIRY COWS AND THOSE
INDIVIDUALS AT INCREASED RISK.
CONVENIENT WITH PROVEN EFFICACY, THAT’S THE BEAUTY OF BOVIKALC®
For reduction of the risk of milk fever:
- 1st bolus at the first sign of parturition.
- 2nd bolus immediately after calving.
- If necessary, give 1 or 2 additional boluses at 12–15 hour intervals.
For supplementation following calcium injection:
- 1st bolus 2–3 hours after calcium injection.
- 2nd bolus 12–15 hours later.
Provided that cows can raise their head and are starting to eat and drink. Bovikalc® must not be given to cows with clinical signs of milk fever as the swallowing reflex may be impaired. Do not give the bolus to a down cow (paresis). Only administer using the Bovikalc® branded applicator. It is recommended that a veterinary surgeon or nutritional expert’s advice is sought before use.
