See why progressive dairy producers like Jim Weber of Level Acres Dairy in Wisconsin consider RumiLife CAL24 to be a key part of their fresh cow protocols.

Is it your goal to create a herd of healthy, productive, trouble-free cows?

Those are the type we call Alta 4-EVENT COWS because they have just four main events that show up on their cow card through their lactation: 1-FRESH, 2-BRED, 3-PREG, and 4-DRY.

RumiLife CAL24 is a simple, effective way to improve the FRESH event for your herd. Get your cows off to the right start after calving. Give one dose of two RumiLife CAL24 boluses to promote proper calcium levels throughout that critical first 24 hours of lactation.

Why address subclinical milk fever?

You might not see it, but it’s there. Subclinical milk fever can affect as many as half of your cows in their second and greater lactations. It can prevent cows from earning 4-EVENT COW status. You don’t see outward signs or symptoms, but that hidden calcium imbalance in your fresh cows can lead to more issues – and lost profit. RumiLife CAL24 can help prevent it.


In general, half of your mature cows will have subclinical milk fever after freshening


One case of subclinical milk fever is expensive


Subclinical milk fever can cost you four times more than clinical cases in your herd

Other Issues

▪ Mastitis ▪ Retained Placenta ▪ Displaced Abomasum ▪ Future Reproductive Challenges
▪ Decreased Milk Production

RumiLife® CAL24™ FAQ

The product should be used at freshening to help promote proper calcium and magnesium levels. RumiLife® CAL24™ nutritional supplement can also be used in instances associated with low calcium levels, such as supporting high-producing cows later in lactation. The product can also be given 2-3 hours after a calcium injection to help provide sustained release supplementation.

Producers should give two boluses (a one-dose package) at freshening. The product can also be given during other times of low calcium levels

It is possible to administer just one bolus. However, giving one bolus to a cow at freshening will sustain proper calcium levels for just 12 hours. The full dose of two boluses will sustain calcium levels for a full 24-hour period.

Yes! The bolus is not only a tapered shape, but it’s also got a slick coating for safe and easy administration, even in Jerseys.

There are two forms of calcium in RumiLife® CAL24™ nutritional supplement. Calcium Chloride is fast-acting and immediately available in the rumen. Calmin offers sustained release calcium in the cow’s system.

Calmin is a highly available and absorbable form of calcium and magnesium derived from calciferous sea algae. Calmin has been
tested to be more absorbable than other forms of supplemental calcium. The unique structure of Calmin allows a cow to break
down and absorb the calcium before it passes through the digestive system.

Vitamin D has long been known for its importance in calcium absorption. Magnesium plays a vital role in the cow’s parathyroid gland, as it relates to the natural regulation of blood calcium levels. RumiLife® CAL24™ nutritional supplement was designed to fully encompass a cow’s need for supplemental calcium and to support the cow’s homeostatic mechanisms that control blood calcium levels during the first 24 hours after calving and other times associated with low calcium levels.

No, it does not replace a calcium IV. If a cow is down with clinical milk fever, you should still administer an IV calcium solution. However, RumiLife® CAL24™ nutritional supplement can be given after the IV to help maintain blood calcium levels.

The shelf life of the product is two years.
