Results from milk progesterone assays can provide ovarian information, making it possible to monitor the reproductive status of the cow. Rapid, simple, and accurate on-farm milk progesterone tests are commercially available. Procedures for performing milk progesterone tests are specific for each test; however, principles of testing are similar. On-farm tests are designed to determine the relative progesterone concentration ("high" or "low") rather than obtaining a precise concentration. Evaluation of results is based on either a color or agglutination reaction with comparison to known standards. Potential uses of progesterone testing in a reproductive management program are: 1) identifying errors in detection of estrus, 2) predicting time of estrus, 3) assisting in pregnancy diagnosis, 4) differentiating types of ovarian cysts, and 5) evaluating response to endocrine therapy.
牛奶孕酮检测结果能够提供卵巢相关信息，从而监测奶牛的繁殖状态。市面上有快速、简便且准确的农场牛奶孕酮检测方法。每种牛奶孕酮检测的操作流程都有其特殊性，但检测原理相似。农场检测旨在确定孕酮的相对浓度（“高”或“低”），而非获取精确浓度。检测结果通过与已知标准进行颜色或凝集反应来评估。孕酮检测在繁殖管理计划中的潜在用途包括：1）识别发情检测中的错误；2）预测发情时间；3）辅助妊娠诊断；4）区分卵巢囊肿类型；5）评估内分泌治疗的效果。
