This project will support the dairy industry by addressing targeted emerging and unmet needs identified by our partners in the National Dairy Research Strategy. We developed this project with our industry partners, Dairy Farmers of Ontario, Dairy Farmers of Canada, Lactanet, and Veal Farmers of Ontario. Meeting our partners' needs based on consumers' expectations requires sustainable production of milk from healthy animals. We will complete 15 studies over 5 years with two pillars of investigation. Theme 1 supports sustainable milk production by addressing critical health, environmental, and economic concerns that face the Canadian dairy industry. We will determine optimal reproduction targets considering profitability, animal health, and environmental impacts, optimize reproductive performance with minimal use of reproductive hormones, improve detection methods for uterine inflammation, identify factors contributing to a successful transition to lactation, and understand barriers to adoption of best management practices. We will quantify the effects of disease in early life on the longevity and productivity of dairy cows. Our work will develop and validate decision supports to reduce antimicrobial use to treat diarrhea in calves. Theme 2 addresses key infectious disease and biosecurity concerns on Canadian dairy farms. We will focus several studies on enzootic bovine leukosis and Salmonella Dublin, gaining new insights into how and when these diseases are spread. We will apply that new knowledge to develop new strategies for control and test these under real-world conditions. We will develop and validate industry-scale infectious disease surveillance using bulk tank milk, and uncover the transmission networks that allow for spread of disease between farms. We will implement a comprehensive knowledge translation and transfer plan including peer-reviewed publications, as well as videos, lay articles, and social media to ensure the results reach and are implemented by producers. We will make actionable progress on high priority issues to position the Canadian dairy industry to sustain efficient production from healthy animals that meets social expectations and supports consumer demand.

该项目将通过满足我们的合作伙伴在国家乳制品研究策略中确定的有针对性的新兴需求来支持乳业行业。我们与我们的行业合作伙伴，安大略省的乳业农民，加拿大的奶农，乳狮和安大略省的小牛肉农民一起开发了这个项目。 根据消费者的期望满足我们的伴侣的需求需要可持续的健康动物牛奶生产。我们将在5年内完成15项研究，并进行两个调查支柱。主题1通过解决加拿大乳制品行业的关键健康，环境和经济问题来支持可持续的牛奶生产。 我们将确定考虑盈利能力，动物健康和环境影响的最佳繁殖目标，通过最少使用生殖激素来优化生殖性能，改善子宫炎症的检测方法，确定导致成功过渡到哺乳过渡的因素，并了解采用最佳管理实践的障碍。我们将量化疾病对早期生命的影响对奶牛的寿命和生产力。我们的工作将制定并验证决策支持，以减少抗菌用途以治疗小牛的腹泻。主题2解决了加拿大奶牛场的关键传染病和生物安全问题。 我们将把几项研究集中在恩Zootic牛白细胞和都柏林沙门氏菌上，对这些疾病的传播方式以及何时扩散有了新的见解。 我们将应用这些新知识来制定新的策略来控制和在现实世界中测试这些知识。我们将使用散装罐牛奶来开发和验证行业规模的传染病监测，并发现可以在农场之间传播疾病的传输网络。我们将实施全面的知识翻译和转移计划，包括经过同行评审的出版物以及视频，外行文章和社交媒体，以确保结果达到并由生产者实施。我们将在高优先问题上取得可行的进展，以将加拿大乳制品行业定位，以维持满足社会期望并支持消费者需求的健康动物的有效生产。
