Stimulate weight gain and improve feed efficiency in cattle with Ralgro Zeranol Implants from Merck Animal Health. Zeranol stimulates the pituitary gland of the animal to produce increased amounts of somatotropin, the animal's own natural growth-promoting agent. Zeranol is not an estrogen, which is found in other implants.

Increases rate of weight gain and improves feed conversion of weaned beef calves, growing beef cattle, feedlot steers and feedlot heifers. Also increases rate of weight gain of suckling beef calves. The active ingredient, Zeranol, stimulates the animal's own natural growth system.

Ralgro Implants are packaged in round cartridges containing 24 doses. Each dose is 3 small pellets containing a total of 36 mg of Zeranol. The dose is the same for heifers, steers and calves.

Ralgro is for calves, stockers & feedlot cattle. Approximately 70 effective days.

How is Ralgro Implanted? Optimal absorption of Ralgro Implants are dependent on proper placement of the implanted pellets, made simple with the easy-to-use Ralgrogun® Pellet Injector - QC Part #540092, sold separately. The Ralgrogun® is one of the most reliable implant devices in the industry. Its small needle diameter reduces tissue trauma and increases the likelihood of proper placement, contributing to the effectiveness of the implant. The Ralgrogun comes with a lifetime guarantee.
