‘O’ Cal-D™ | Calcium & Vitamin D Supplement for Dairy Cattle

'O' Cal-D Cap™ by Bio-Vet is a calcium capsule supplement formulated for adult dairy cattle at calving time, providing 30 grams of calcium per feeding alongside 20,000 IU of Vitamin D3 to support healthy calcium utilization. This capsule delivers rapid and sustained release forms of calcium in one product, ensuring calcium is available to the cow both quickly and over time during the critical period around calving. Vitamin D3 (20,000 IU) is included to aid in calcium utilization, supporting the body's ability to absorb and use the calcium provided. At calving, dairy cows experience a significant increase in calcium demand as milk and colostrum production begins. Supporting healthy calcium levels during this period is an important part of fresh cow management and overall transition cow health. 'O' Cal-D Cap capsules fit standard cattle applicators for easy, convenient administration. For best results, use in conjunction with 'O' RumenAider® capsules as part of a comprehensive fresh cow protocol.
