Implantation or Injectable Dosage Form New Animal Drugs; Trenbolone and Estradiol; Technical Amendment

Resumo

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental abbreviated new animal drug application (ANADA) filed by Ivy Laboratories, Division of Ivy Animal Health, Inc. The supplemental ANADA provides for an additional dose of trenbolone acetate and estradiol implant for use in feedlot steers for increased rate of weight gain and improved feed efficiency. This section of the regulations is also being amended to remove a redundant description of another strength implant. This action is being taken to improve the accuracy of the regulations.
