Boosting calcium levels with RumiLife CAL24 calcium boluses is the best way to mitigate these risks, alleviate costly fresh cow issues, and help your cows transition smoothly into their lactation. ![Low Calcium Risks](https://us.altagenetics.com/hs-fs/hubfs/Low%20Calcium%20Risks.jpg?width=2000&name=Low%20Calcium%20Risks.jpg) ## Low Calcium Means Lower Milk & Higher Health Risks Subclinical hypocalcemia, also known as milk fever, can be difficult to detect due to the lack of visible signs, but it's there. It can affect as many as half of your cows in their second and greater lactations, and it increases their risk of costly health issues like mastitis, reproductive challenges, and displaced abomasum. Being proactive by using RumiLife® CAL24™ calcium boluses on your cows at freshening is a proven solution to help prevent subclinical hypocalcemia. ![Subclinical Milk Fever](https://us.altagenetics.com/hs-fs/hubfs/Subclinical%20Milk%20Fever.png?width=642&height=64&name=Subclinical%20Milk%20Fever.png) 50% of your mature cows likely experience subclinical milk fever after freshening. ![Subclinical Milk Fever Costs](https://us.altagenetics.com/hs-fs/hubfs/Subclinical%20Milk%20Fever%20Costs.png?width=62&height=64&name=Subclinical%20Milk%20Fever%20Costs.png) One case of subclinical milk fever can cost you $125–four times more than the clinical cases in your herd. ![Health Issues](https://us.altagenetics.com/hs-fs/hubfs/Health%20Issues.png?width=64&height=64&name=Health%20Issues.png) Cows that experience subclinical milk fever are more prone to other health issues. ## Why Choose RumiLife® CAL24™? ![CAL24 SIMPLE](https://us.altagenetics.com/hs-fs/hubfs/Alta_Genetics_June2025/Icons/CAL24%20SIMPLE.png?width=100&height=133&name=CAL24%20SIMPLE.png) ### It's SIMPLE - Save time and labor–give two boluses right after calving; no need to catch each cow to give a second bolus 12 hours later - Slick coating and the tapered shape mean it’s easy to administer ![CAL24 Unique](https://us.altagenetics.com/hs-fs/hubfs/Alta_Genetics_June2025/Icons/CAL24%20Unique.png?width=75&height=100&name=CAL24%20Unique.png) ### It's UNIQUE - The only calcium product with a one-time application recommendation - Formulated with two actively effective forms of calcium, plus magnesium and vitamin D to promote optimal calcium absorption ![CAL24 Complete](https://us.altagenetics.com/hs-fs/hubfs/Alta_Genetics_June2025/Icons/CAL24%20Complete.png?width=75&height=100&name=CAL24%20Complete.png) ### It's COMPLETE - Provides immediate and sustained release calcium - Calcium chloride acts rapidly for immediate absorption in the rumen - Calmin regulates absorption over time as a combination of highly absorbable calcium and magnesium - Vitamin D helps facilitate active, sustained calcium transfer beyond the rumen ![pulse-4-outline bg@2x](https://2474026.fs1.hubspotusercontent-na1.net/hub/2474026/hubfs/Alta_Genetics_June2025/Image/pulse-4-outline%20bg@2x.png?width=1737&height=1901&name=pulse-4-outline%20bg@2x.png) ## RumiLife CAL24 is OMRI Listed to the USDA National Organic Program standards for its use in organic livestock and dairy production.** ** [See the Certificate Here](https://us.altagenetics.com/hubfs/CAL24-OMRI-United-States-Certificate-2023-2024.pdf?hsLang=en) ## Frequently Asked Questions ### Product Overview #### **What is RumiLife® CAL24™?** The product should be used at freshening to help promote proper calcium and magnesium levels. RumiLife® CAL24™ nutritional supplement can 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 administering an IV calcium solution to help provide sustained release supplementation. #### **What is Calmin?** 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. #### **Why does RumiLife® CAL24™ contain Vitamin D and Magnesium?** 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. #### **Is RumiLife® CAL24™ organic?** RumiLife CAL24 is OMRI Listed to the USDA National Organic Program standards for its use in organic livestock and dairy production.  [View Certification](https://us.altagenetics.com/wp-content/uploads/2024/07/CAL24-OMRI-United-States-Certificate-2023-2024.pdf?hsLang=en) ### Dosage & Administration #### **What is the recommended dosage?** Producers should give two boluses (a one-dose package) at freshening. The product can also be given during other times of low calcium levels. #### **Can I just give one bolus to fresh cows instead of two?** It is possible to administer just one bolus. Administering only one bolus at freshening will support calcium levels for 12 hours, while the recommended two-bolus dose extends support for a full 24-hour period. #### **Is the product easy to administer?** Yes! The bolus is not only a tapered shape, but it also has a slick coating for safe and easy administration, even in Jerseys. ### Calcium Sources & Effectiveness #### **What types of calcium are found in the product?** 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. #### **Does RumiLife® CAL24™ replace a calcium IV?** 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 3-4 hours after the IV to help maintain blood calcium levels. ### Product Shelf Life #### **What is the shelf life of RumiLife® CAL24™ nutritional supplement?** The shelf life of the product is two years. ## How to Use Locking up cows twice can be a hassle. By using RumiLife CAL24, you save time by only having to lock your fresh cows up once to administer one dose of two boluses. Step 1 Step 2 Step 3 Step 4 ### Step 1 Work with your Alta advisor to determine a fresh cow protocol and identify which cows will receive RumiLife CAL24. ### Step 2 Lock up your fresh cows within 24 hours of calving. ### Step 3 Load both RumiLife CAL24 boluses into the easy-to-use double-bolus applicator, or load one bolus at a time into a single-bolus applicator. ### Step 4 Deposit the boluses into the cow's mouth using the applicator.
