Freshening puts an enormous calcium demand on a dairy cow right when she can least afford to fall short. Cal-Boost® gives you an oral calcium bolus built to meet that demand fast and keep it covered through the critical hours after calving.

Each bolus combines immediate-release calcium chloride with sustained-release calcium sulfate, so you get a fast initial boost followed by continued calcium support instead of a single spike that fades too soon. Vitamin D3 is included as well, since it's necessary for the body to properly absorb and metabolize both calcium and phosphorus.

The minimum protocol calls for one bolus immediately after calving and a second 12 to 24 hours later, administered using the Cal-Boost® branded applicator. For high-yielding cows, an extended protocol adds boluses at the first signs of parturition and again at 24 to 48 hours after calving, giving extra coverage through the highest-risk window. Talk with your veterinarian before implementing either protocol.

Each case comes with 24 boluses at 7.05 oz per bolus, enough to get a herd through calving season without scrambling for more mid-run. There's no withdrawal period for meat and no withholding time for milk required when used according to label, so it fits right into your existing routine.

Give freshening cows the calcium support they need when the demand is highest, and help set them up for a stronger start to lactation.
