Biosecurity 2.0 for the modern Canadian dairy farm

加拿大乳制品行业是加拿大经济的关键贡献者。2018年，它创造了66亿美元的农场净收入和177亿美元的食品销售。然而，疾病在牛群中的引入和传播是对奶牛场盈利的持续威胁。与其他类型的动物生产系统不同，在其他类型的动物生产系统中，设施可以减少人口、净化和重新填充，奶牛场必须处理连续的生产系统，因此，防止疾病在农场中传播和传播是至关重要的。因此，现在至关重要的是，我们的加拿大乳制品生产商必须实施以强有力的科学证据为基础的生物安全计划。然而，一个主要的障碍是缺乏对牛奶生产中的生物安全进行尖端研究的加拿大科学家。我们研究的主要目标是加快奶牛场生物安全尖端研究的发展，并培养该领域的高素质人员，他们将进一步支持乳制品行业建立最有效的生物安全计划。 拟议的研究计划将涵盖三个主题。第一个研究主题将是确定控制和/或预防疾病传入的关键生物安全做法。在这一主题下进行的研究将能够确定对疾病控制和预防有最大影响的生物安全做法，同时考虑与农场适用性有关的所有方面。这些研究将在预防疾病传播方面支持制定尽可能最佳的生物安全计划，但也将根据以最佳方式应用并被加拿大生产商广泛采用的可能性来支持。我们的第二个研究主题将旨在验证快速、稳健和有效的诊断战略，以支持建立健全的生物安全计划。我们的第三个研究主题将致力于开发具有成本效益的疾病监测和控制计划。这些计划将支持奶制品生产商、政府和兽医控制各种奶牛疾病的日常工作。

The Canadian dairy industry is a key contributor to the Canadian economy. In 2018, it generated $6.6B in net farm receipts and $17.7B in food sales. However, the introduction and spread of diseases in a herd is a constant threat to a dairy farm's profitability. Unlike other types of animal production systems, where facilities can be depopulated, decontaminated, and repopulated, dairies must deal with a continuous production system and, therefore, preventing introduction and spread of diseases in a farm is critical. For that reason, it is now crucial for our Canadian dairy producers to implement biosecurity plans that are based on strong scientific evidences. A major obstacle, however, is the shortage of Canadian scientists conducting cutting-edge research on biosecurity in milk production. The main objectives of our research are to accelerate the development of cutting-edge research on biosecurity on dairies and to train highly qualified personal in that domain, who will later further support the dairy industry in establishing the most efficient biosecurity programs. The proposed research program will cover three themes. First research theme will be the identification of key biosecurity practices for controlling and/or preventing introduction of diseases. Research conducted under that theme will allow identification of the biosecurity practices that can have the greatest impact on control and prevention of diseases while considering all aspects linked to on-farm applicability. These researches will support development of the best possible biosecurity programs in term of prevention of transmission of disease, but also in term of probability of being applied in an optimal manner and widely adopted by Canadian producers. Our second research theme will aim at validating rapid, robust, and efficient diagnostic strategies for supporting establishment of robust biosecurity programs. Our third research theme will be dedicated to the development of cost-efficient disease surveillance and control programs. These programs will support dairy producers, governments, and veterinarians in their daily work for controlling various dairy cattle diseases.
