Identifying superior animals in the breeding program will improve sow lifetime productivity (SLP) and the number of quality pigs marketed per sow and thus will have a positive impact on overall profitability and sustainability of the Canadian pork industry. Sow lifetime productivity is a complex trait that involves interactions between the genetic potential, the underlying physiological mechanisms and the reproductive management practices implemented on farm. Sow lifetime productivity is also an important component of sow welfare and sustainability and it is of particular relevance to current industry trends.In the proposed project, we will identify the underlying genetic and phenotypic relationships between different traits in order to achieve more balanced selection to improve SLP and production profitability. We will identify the key physiological components of gilt eligibility at first service to lay the foundation for improved productivity and longevity and develop new rearing and management guidelines to ensure the improved genetic potential is expressed in commercial sow herds. Ultimately, we hypothesize this will improve overall production efficiency and result in improved competitiveness and sustainability of the Canadian pig industry. The value of the expected results from this project will benefit our industry partner, the swine industry in Canada and worldwide. We will ensure the transfer of results and application in the swine industry and support the adoption of new knowledge at the commercial level, directly translating research to adoption by producers. The project will provide opportunities for highly qualified personnel in both genetics and precision pig production.

在繁殖计划中识别出色的动物将提高母猪寿命生产率（SLP）和每种母猪销售的优质猪的数量，因此将对加拿大猪肉行业的整体盈利能力和可持续性产生积极影响。 SOW寿命生产率是一个复杂的特征，涉及遗传潜力，潜在的生理机制和在农场实施的生殖管理实践之间的相互作用。 SOW寿命生产率也是母猪福利和可持续性的重要组成部分，它与当前的行业趋势特别相关。在拟议的项目中，我们将确定不同特征之间的基本遗传和表型关系，以实现更平衡的选择以提高SLP和生产盈利能力。我们将确定第一次服务中镀金资格的关键生理组成部分，以提高生产率和寿命，并制定新的饲养和管理指南，以确保在商业母猪群中表达改善的遗传潜力。最终，我们假设这将提高整体生产效率，并改善加拿大猪行业的竞争力和可持续性。该项目的预期结果价值将使我们的行业合作伙伴，加拿大和全球的猪行业受益。我们将确保在猪行业中的结果和应用转移，并支持在商业层面采用新知识，将研究直接转化为生产者的收养。该项目将为高素质的遗传学和精确猪生产提供机会。
