Breeding Soundness Evaluations (BSEs) are a useful tool to improve reproductive performance and profitability in beef herds. Veterinarians providing this service must be thorough in their evaluation, especially in yearling bulls. The 1993 Society for Theriogenology guidelines for BSE provide appropriate standards for classifying yearling bulls; veterinarians are advised to adhere to these standards as minimums for classification of the satisfactory potential breeder.
繁殖健全性评估（BSEs）是提高肉牛群繁殖性能和盈利能力的一项有用工具。提供这项服务的兽医在评估时必须全面，尤其是对一岁公牛。1993年兽医学协会的BSE指南为一岁公牛的分类提供了适当标准；建议兽医将这些标准作为判定潜在种公牛是否合格的最低标准予以遵守。
