Justification for administering feed additives

摘要

Nutritionists and poultry health professionals are constantly faced with a decision as to whether to treat flocks by adding antibiotics or other approved compounds to hen diets in the event of a decline in production. The Food and Drug Administration(FDA) has the legal authority to approve the use of all feed additives based on efficacy and safety criteria. Approved additives either alone or in combination are listed in reference texts and specific details on addition rates, the Material Safety Data Sheets and statutory withdrawal periods are provided by manufacturers. Statutory label instructions must be followed and a review of suppliers' supplementary literature is strongly advised.
