Zoetis’ SYNOVEX CHOICE implant has been approved for feedlot heifers to help increase average daily gain and improve feed efficiency. The U.S. Federal Drug Administration (FDA) has determined SYNOVEX CHOICE is not expected to have a significant impact on the environment—waterways, air, plants or aquatic species—when used according to label directions.
Bovine Veterinarian reports for more than 12 years SYNOVEX CHOICE has helped optimize weight gain in feedlot steers through the 10:1 ratio of trenbolone acetate (TBA) to estradiol-17B (E2).1. The U.S. Food and Drug Administration (FDA) approval for use in heifers means feedlot managers can use the same implant for all cattle.
