Merck Ralgro Implants- 24 Count

Active Ingredient(s): Each implant contains 36 mg zeranol (three pellets, each containing 12 mg zeranol). Zeranol, the active drug in RALGRO®, is a derivative of resorcylic acid lactone fermentation product.

Dosage and Administration: The dose for all classes of beef cattle is 36 mg (three 12 mg pellets). The implant site is subcutaneous, between the skin and cartilage on the back side of the ear and below the midline of the ear. The implant must not be placed closer to the head than the edge of the auricular cartilage ring furthest from the head. The location for insertion of the needle is a point toward the tip of the ear and at least a needle length away from the intended deposition site. Care should be taken to avoid injuring the major blood vessels or cartilage of the ear. Squeeze the trigger of the Ralogun® to deliver a full dose of RALGRO®. Keep the trigger depressed while withdrawing the needle to be sure that the RALGRO® implants stay in place.

Caution(s):

• FOR ANIMAL USE ONLY.
• Do not use in bulls intended for reproduction or dairy animals.
• Do not use before one month of age or after weaning in heifers intended for reproduction.
• Edema of the vulva and udder, teat elongation, rectal and vaginal prolapse, and signs of estrus may occur when heifers are implanted. Delayed testicular development may occur in young males. To avoid difficulty in castration, young males should be castrated at the time of implanting.
