Two areas of drug needs in the sheep industry are reviewed. The first is the need for prolificacy drugs such as those used outside the country. These drugs would encourage out-of-season lambing, increased lambs/per ewe during the traditional lambing season and synchronize estrus for easier management of lambing and increased use of artificial insemination for faster genetic improvement. The other area is drugs to treat or prevent major causes of disease, specifically abortion, neonatal diarrhea, pneumonia and internal parasitism. Efficacious drugs for these diseases are either not now cleared for use in sheep at all; a safe, easy to administer product is not available; or not cleared for sheep at a dosage level which is effective. These are drugs which will have a positive impact on the industry by increasing production, reducing expenses, and helping the U. S. to be able to compete with other sheep producing countries in the U. S. markets.
本文综述了养羊业中两个药物需求领域。第一个领域是对繁殖药物的需求，比如国外使用的那些药物。这些药物可促进非繁殖季节产羔，在传统产羔季节提高每只母羊的产羔数，并使发情同步化，以便更轻松地管理产羔过程，还能增加人工授精的使用频率，从而更快地实现遗传改良。另一个领域是用于治疗或预防主要疾病病因的药物，特别是流产、新生羔羊腹泻、肺炎和体内寄生虫病。针对这些疾病的有效药物要么目前根本未获批用于绵羊；要么没有安全、易于给药的产品；要么在有效剂量水平下未获批用于绵羊。这些药物将通过提高产量、降低成本以及帮助美国在国内市场与其他养羊国家竞争，对该行业产生积极影响。
