Deep Blue Calcium Bolus – Your Top Choice for Post Calving Calcium
Release time:
2026-08-31
Functions and Indications
Calcium Chloride and Calcium Sulfate provide both immediate and ongoing calcium for fresh cows after calving.
Product Features & Benefits
1.Sustained Release: Advanced polymer matrix enables slow, persistent calcium ion release within the rumen
2.Fast-Acting: Ionic calcium chloride (CaCl2) provides rapidly available calcium to elevate blood concentration.
3.Acidifying Effect: Promotes the cow's own skeletal calcium mobilization through metabolic acidification.
4.Secondary Disease Prevention: Reduces the incidence of displaced abomasum, retained placenta, metritis, and other postpartum complications, supporting faster return to peak production.
5.Palatability-Enhanced Coating: Special coating masks the bitter taste of calcium preparations, ensuring smooth, non-irritating administration.
Calcium Loss: The Numbers Behind the Need
Lactation is the primary driver of blood calcium decline—the higher the milk yield, the greater the calcium loss. Dietary calcium is the only external source of calcium for dairy cows. On calving day, cows often have little to no appetite, yet lactation begins immediately. A cow producing 15 kg of colostrum loses approximately 40 grams of calcium, including losses through urine and feces.
Our Deep Blue Calcium Bolus is labeled with a calcium content of ≥21%, with actual measured calcium exceeding 44 grams per bolus—a single administration is sufficient to replenish the calcium lost to lactation.
Clinical Trial: Deep Blue Calcium on a 10,000-Head Commercial Farm
In a large-scale trial conducted on a 10,000-head dairy farm, six cows (No. 1–6) approaching calving were randomly selected. Immediately after calving, each cow received one calcium bolus. Blood samples were collected at 0h, 2h, 6h, 8h, and 12h post-administration to measure serum ionized calcium levels. The normal reference range for dairy cows is 1.06–1.33 mmol/L.
The results demonstrated that Deep Blue Calcium Bolus effectively raised and sustained blood calcium within the normal range throughout the critical 12-hour post-calving window, confirming its efficacy in both immediate calcium delivery and prolonged maintenance.
Conclusion
Postpartum hypocalcemia remains one of the most underestimated threats to dairy herd health and profitability. With its dual-action formulation combining immediate-release and sustained-release calcium, Deep Blue Calcium Bolus offers a science-backed, practical solution for both prevention and treatment. Protect your fresh cows, protect your bottom line—choose Deep Blue Calcium.
