The decline in dairy herd fertility internationally has highlighted the limited impact of traditional veterinary approaches to bovine fertility management. Three questionnaire surveys were conducted at buiatrics conferences attended by veterinary practitioners on veterinary dairy herd fertility services (HFS) in countries with a seasonal (Ireland, 47 respondents) and non-seasonal breeding model (The Netherlands, 44 respondents and Portugal, 31 respondents). Of the 122 respondents, 73 (60%) provided a HFS and 49 (40%) did not. The majority (76%) of all practitioners who responded stated that bovine fertility had declined in their practice clients' herds with inadequate cow management, inadequate nutrition and increased milk yield as the most important putative causes. The type of clients who adopted a herd fertility service were deemed more educated than average (70% of respondents), and/or had fertility problems (58%) and/or large herds (53%). The main components of this service were routine postpartum examinations (95% of respondents), fertility records analysis (75%) and ultrasound pregnancy examinations (69%). The number of planned visits per annum varied between an average of four in Ireland, where breeding is seasonal, and 23 in Portugal, where breeding is year-round. The benefits to both the practitioner and their clients from running a HFS were cited as better fertility, financial rewards and job satisfaction. For practitioners who did not run a HFS the main reasons given were no client demand (55%) and lack of fertility records (33%). Better economic evidence to convince clients of the cost-benefit of such a service was seen as a major constraint to adoption of this service by 67% of practitioners.
国际范围内奶牛群繁殖力的下降突显了传统兽医方法在牛群繁殖管理方面的作用有限。在兽医奶牛群繁殖力服务（HFS）的布尤蒂克斯会议上，对兽医从业者进行了三次问卷调查，这些会议分别在爱尔兰（季节性繁殖模式，47 名受访者）、荷兰（非季节性繁殖模式，44 名受访者）和葡萄牙（31 名受访者）举行。在 122 名受访者中，有 73 名（60%）提供了 HFS，49 名（40%）没有提供。所有回答问题的从业者中，有 76%的人表示，他们所在的实践客户的牛群繁殖力已经下降，主要原因是牛的管理不善、营养不足和产奶量增加。采用 HFS 的客户类型被认为比平均水平更有文化（70%的受访者），并且/或者存在繁殖问题（58%）和/或拥有大型牛群（53%）。该服务的主要内容包括产后常规检查（95%的受访者）、繁殖记录分析（75%）和超声妊娠检查（69%）。每年计划的访问次数在爱尔兰（季节性繁殖，平均每年 4 次）和葡萄牙（全年繁殖，每年 23 次）之间有所不同。开展 HFS 对从业者及其客户的好处包括更好的繁殖力、经济回报和工作满意度。对于不开展 HFS 的从业者，主要原因是客户没有需求（55%）和缺乏繁殖记录（33%）。67%的从业者认为，缺乏能够使客户相信这种服务具有成本效益的经济证据，这是采用这种服务的主要限制因素。
