奶牛养殖业在英国和世界经济中扮演着重要的角色。乳品业的可持续性目前正面临重大挑战。奶牛不孕不育仍然是限制牛群生产力的一个重要问题，仅在英国就导致每年数亿英镑的损失。为了解决这一问题，准确监测每头奶牛的生殖状况并及早发现生育问题至关重要。这项研究的目的是收集农民和兽医对英国奶牛场目前的做法和与生育问题诊断和怀孕测试相关的差距的看法。通过在线问卷调查，共收集了40名农民和59名兽医的数据并进行了分析。结果显示，看不见的公牛检查和超声波是最常见的检测生育问题的工具，大多数农民在产犊后进行测试，而且经常在交配前或交配期间再次测试。大多数农民认为，目前的测试没有达到他们的预期，有一半的农民愿意支付比目前更高的生育力测试费用。关于怀孕测试，最常用的是超声波，在授精后30-50天，无论是对个体奶牛还是对奶牛群体。同样，大多数农民认为目前的测试没有达到他们的预期，大多数人会考虑为比目前可用的测试更好的测试支付更高的成本。此外，大多数农民会考虑使用一种可以在授精后2周内发现怀孕的测试，如果存在这种测试的话，因为他们相信这将有助于改善他们的牛群的繁殖性能。总体而言，农民和兽医的意见表明，通过开发可以更早诊断怀孕和不孕不育、对农场运营的干扰较小且比现有工具更具成本效益的改进化验方法，英国的奶牛繁殖力监测实践有很大的改进空间。它们也为今后开发和实施更好的诊断方法以提高奶牛的繁殖性能提供了有用的信息。
Dairy cow farming plays an important role in the UK and worldwide economies. Significant challenges are currently being faced regarding sustainability of the dairy industry. Dairy cow subfertility remains an important issue limiting herd productivity, resulting in annual losses of hundreds of millions of pounds in the UK alone. To address this, accurate monitoring of reproductive status and early detection of fertility issues in individual cows is essential. The aim of this study was to gather farmer and veterinarian opinions on current practices and perceived gaps related to diagnosis of fertility issues and pregnancy testing in UK dairy farms. Using online questionnaires, data were collected and analyzed from a total of 40 farmers and 59 veterinarians. The results showed that non-seen bulling checks and ultrasound were the most frequent tools to detect fertility issues, and that most farmers tested post-calving, and often again before or during mating. Most farmers believed that current tests did not meet their expectations, with half of those being willing to pay more than they were currently paying for fertility testing. In regard to pregnancy testing, ultrasound was most commonly used, at 30–50 days post-insemination either in individual or groups of cows. Again, most farmers believed that current tests did not meet their expectations, and a majority would consider paying a higher cost for a test that was better than those currently available. In addition, a majority of farmers would consider using a test that could detect pregnancy within 2 weeks post-insemination, if such test existed, because they believed it would help improve their herds' reproductive performance. Overall, the opinions of farmers and veterinarians indicate that there is significant scope for improving dairy herd fertility monitoring practices in the UK, through development of improved assays that can diagnose pregnancy and infertility earlier, are less disruptive to farm operations and are more cost effective than available tools. They also provide useful information to guide the future development and implementation of better diagnostics for improving reproductive performance of dairy cattle.
