Veterinary herd health management (VHHM) programmes have been shown to be economically effective in the past. However, no current information is available on costs and benefits of these programmes. This study compared economics and farm performance between participants and non-participants in VHHM programmes in 1013 dairy farms with over 40 cows. Milk Production Registration (MPR) data and a questionnaire concerning VHHM were used. Based on the level of participation in VHHM (as indicated in the questionnaire), costs of the programmes were calculated using a normative model. The economic value of the production effects was similarly calculated using normative modelling based on MPR data. Participants in VHHM had a better performance with regard to production, but not with regard to reproduction. Over 90 per cent of the VHHM participants were visited at least once every six weeks and most participants discussed at least three topics. In most farms, the veterinarian did the pregnancy checks as part of the VHHM programmes. There was a benefit to cost ratio of about five per cow per year for VHHM participants, and a mean difference in net returns of €30 per cow per year after adjusting for the cost of the programme. This portrays that participation in a VHHM programme is cost-efficient. There is, however, much unexplained variation in the net returns, possibly due to diverse approaches by veterinarians towards VHHM or by other factors not included in this analysis, like nutritional quality or management abilities of the farmer.
过去已证明兽医畜群健康管理（VHHM）计划具有经济效益。然而，目前尚无关于这些计划成本和效益的信息。本研究比较了1013个拥有40头以上奶牛的奶牛场中参与和未参与VHHM计划的农场之间的经济情况和农场绩效。使用了牛奶生产登记（MPR）数据和一份关于VHHM的问卷。根据问卷中显示的VHHM参与程度，使用规范模型计算计划成本。同样根据MPR数据，使用规范模型计算生产效应的经济价值。VHHM的参与者在生产方面表现更好，但在繁殖方面并非如此。超过90%的VHHM参与者每六周至少接受一次访问，大多数参与者至少讨论了三个主题。在大多数农场，兽医作为VHHM计划的一部分进行妊娠检查。VHHM参与者每头奶牛每年的效益成本比约为5，在扣除计划成本后，每头奶牛每年的净收益平均差异为30欧元。这表明参与VHHM计划具有成本效益。然而，净收益中存在许多无法解释的差异，这可能是由于兽医对VHHM的不同方法，或者是由于本分析中未包括的其他因素，如农民的营养质量或管理能力。
