Lokale automatische Übersetzung · Originalsprache der Quelle
Zusammenfassung
The Food and Drug Administration (FDA) has withdrawn approval of two new animal drug applications (NADAs) for a suspension implant of estradiol benzoate microspheres used in steers and heifers fed in confinement for slaughter for increased rate of weight gain and improved feed efficiency, and in suckling beef calves for increased rate of weight gain. In a final rule published elsewhere in this issue of the Federal Register, FDA is amending the animal drug regulations to remove portions reflecting approval of these NADAs.
