40 years of Elanco's Compudose

Compudose™ Important Information

Compudose contains a naturally occurring hormone oestradiol 17ß, which is found in all mammals. Compudose stimulates the pituitary gland resulting in the release of the animal’s own natural growth hormone.

Dosage and Administration

Insert one implant under the skin on the back side of the middle 1/3 of the ear per animal. Use a Compudose implanter only. Do not penetrate cartilage. To help avoid abscess formation at the implant site, thoroughly clean and disinfect the surface of the ear before implantation. Implanted cattle must be individually identified with an approved ear punch mark. Refer to label for full directions.
