UltraCruz Cattle Copper Bolus for Beef and Dairy Cattle provides a beneficial source of Copper designed for both beef and dairy cattle in an easy-to-use slow release bolus. Copper is an essential trace mineral to help support a healthy coat, boost the immune system, and aid in the prevention of Copper deficiency. These convenient, long-lasting boluses contain Copper Oxide particles to act as a slow-release source of Copper. When the bolus reaches the stomach, the gelatin capsule quickly dissolves to release the Copper particles. The copper then imbed in the rumen and slowly dissolve to gradually release copper. UltraCruz Cattle Copper Bolus for Beef and Dairy Cattle adults is recommended for cattle weighing over 500 lbs. This product is intended for use in cattle only. We offer a variety of balling guns suitable for administering UltraCruz Cattle Copper Bolus for Beef and Dairy Cattle. Developed and manufactured in the USA with globally-sourced ingredients by Santa Cruz Animal Health
