CRSB releases second National Beef Sustainability Assessment

On January 15, 2024, the Canadian Roundtable for Sustainable Beef (CRSB) released its second and highly anticipated National Beef Sustainability Assessment (NBSA) and Strategy report.

The assessment reflects three years of in-depth scientific analysis and highlights the Canadian beef sector’s progress between 2014 and 2021 on sustainability indicators like greenhouse gas emissions, biodiversity, carbon storage, people’s health and safety, animal care, economic contributions and more. 

Key environmental improvements include a 15 per cent reduction in greenhouse gas emissions to produce 1 kg of beef (boneless and consumed) since 2014. The report also shows that land used for beef cattle production is estimated to store 1.9 billion tonnes of soil organic carbon, and with overall loss of habitat, Canadian beef farmers and ranchers play an important role in preserving intact critical habitat wildlife need for reproduction and feeding.

Video: Methionine Requirements for Lactating Sows - Cierra Kozole


In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
