Abstract
Abstract Implementing breeding strategies for a more sustainable food system is one of the most pressing topics for livestock industries. Although different species face different challenges, large-scale research projects can pave the way for future opportunities in these key sectors. Herein, we present two examples (dairy and poultry) of how research projects can result in meaningful changes to commercial breeding programs. The first example is an international large-scale dairy project, which will deliver a roadmap for greenhouse gas (GHG) management using genomics and nutrition. The project aims to facilitate a 55% reduction in GHG emissions from Canadian dairy at an estimated value of $338M CAD. This systems-level approach will leverage resources developed through previous and current large-scale projects to produce accurate multi-level emission estimates and identify opportunities to mitigate enteric GHG emissions. The results of this project will provide accurate, reliable, and robust data for industry stakeholders, national policy, and GHG inventories. The second example is a research collaboration with a commercial turkey breeding company that will enable breeding strategies for long-term and sustainable genetic improvement in health traits. This project aims to reduce preslaughter mortality by 5% and condemnations due to myopathies and health issues. This reduction alone is expected to result in 7.5M kg more turkey meat at a value of $19.8M CAD. Furthermore, there is also an expected reduction of 2.3M kg of CO2 equivalent per year for each 1% livability improvement due to production efficiencies and reduced inputs wasted for more sustainable and ethical meat production. Overall, ongoing and future research initiatives will continue to deliver solutions for key Canadian livestock sectors to improve animal health and welfare as well as efficiency and sustainability. The strides made in these ongoing collaborative projects are imperative for enhancing the sustainability of animal agriculture to feed the growing population.
