Cargill introduces long-acting mineral bolus

Cargill Animal Nutrition Boluses and applicators
Cargill's new Reloader 250 bolus uses timed release to provide minerals for 250 days.
New bolus provides essential trace minerals and vitamins to cattle for 250 days.

Cargill Animal Nutrition says its new Reloader 250 Mineral Bolus is the sure-shot approach to delivering essential trace minerals and vitamins to cattle across the US.

The company says its new bolus is designed to overcome feeding inefficiencies, spillage and other problems and deliver the right amount of mineral for 250 days.

The Reloader 250 Mineral Bolus provides six essential trace minerals and three vitamins. Administered orally by way of a balling gun applicator, the bolus is retained in the reticulum where the timed release technology lasts for 250 days.

Cargill recommends Reloader 250 be administered after the early lactation period. This ensures trace mineral delivery via the bolus until approximately 30 days prior to calving.

“A cow’s trace mineral requirements are highest during early lactation,” said Dr. Abney. “A complete mineral program in which Reloader 250 is administered after early lactation, followed by supplementation with a high-quality, free-choice mineral 30 days prior to calving and through early lactation, is the best approach to meet a cow’s requirements and optimize her performance in many production scenarios," says Dusty Abney, Cargill beef technical specialist.

Reloader 250 is available for purchase online at or through your local Nutrena dealer or Vigortone representative. There are 20- and 40-count boxes available and producers should administer one Reloader 250 bolus per 440 pounds, not to exceed two boluses per head every 250 days. Boluses should be administered by trained personnel, such as a veterinarian or others with significant cattle handling expertise.
