Calcium for Cows that Works When it Matters Most
RumiLife® CAL24™ nutritional supplement is a uniquely formulated bolus that helps fulfill a cow’s calcium needs and combat milk fever after calving. It provides her with rapid and long-lasting calcium absorption to supplement blood calcium levels – all in a two-bolus, one-time application. It provides you with peace of mind.
The ingredients in RumiLife® CAL24™ nutritional supplement allow you to give two calcium boluses immediately after freshening, so you don’t have to catch the cow twice. It’s designed to make your fresh cow management program simpler and provide less stress to the cow.


Fight off milk fever in cows for a full 24 hours after calving.
That first 24 hours after calving can be especially hard on your herd. Your cow’s calcium demands are increasing, as is the potential for calcium deficiency resulting in milk fever. How can you help reduce her likelihood of developing clinical or subclinical milk fever? Ensure her calcium needs are covered with RumiLife® CAL24™ nutritional supplement.
RumiLife® CAL24™ includes two forms of calcium: calcium chloride (a fast-release source of calcium) and Calmin (a slow-release calcium). Calmin is key to 24-hour coverage, as this seaweed-derived, highly available source of calcium and magnesium is a absorbed over time. Simply give her two boluses at freshening – no need to catch her again 12 hours later!

Study shows calcium for cows offers added benefits.
Her health is important during each stage of life. That’s why you need a calcium supplement that not only fights hypocalcemia but also supports her overall health and well-being. A recent research study, with white paper prepared by Rod Riewer, DVM, and Essi Evans, PhD, showed that fresh cows given RumiLife® CAL24™ not only showed fewer incidents of milk fever in fresh cows but also experienced additional health and reproductive benefits.
