Pre-weaning mortality is a major welfare concern for pigs and represents a significant loss of revenue for industry stakeholders. This research partnership will explore novel feeding strategies for sows in late gestation to maximize mammary development and milk production capacity in the subsequent lactation period, while minimizing pre-weaning mortality on Canadian pig farms. The benefits of improving sow milk production capacity include improving sow and offspring performance, reducing the environmental footprint of pork production by maximizing the kilograms of pork produced per sow, and increasing farm profitability and the economic vitality of the Canadian swine industry.

断奶前死亡率是猪的主要福利问题，对行业利益相关者来说是重大的收入损失。该研究伙伴关系将探索妊娠后期母猪的新喂养策略，以最大限度地提高乳房发育和随后哺乳期的产奶量，同时最大限度地降低加拿大猪场断奶前的死亡率。提高母猪产奶量的好处包括提高母猪和后代的生产性能，通过最大限度地提高每头母猪的猪肉产量来减少猪肉生产的环境足迹，提高农场盈利能力和加拿大养猪业的经济活力。
