Animal health program helping B.C. farmers prepare for avian influenza risk

Oct 18, 2023

As the risk of avian influenza increases this fall with the migration of waterfowl and other birds, B.C. poultry farmers are being supported with new planning and preparedness strategies and stronger biosecurity measures on their farms.

“Avian influenza can be devastating for B.C. farmers and have a significant impact on their livelihoods as well as on local economies and food supply,” said Pam Alexis, Minister of Agriculture and Food. “This is why we put a program in place that is now helping them increase their biosecurity measures and providing new tools and strategies to prepare for and respond to any potential outbreak as we head into the fall migration. B.C.’s poultry and egg farmers have shown great dedication to ensure they have the necessary safety measures in place, and we will continue to work closely together with them to protect their animals and our overall food security.”

Video: Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
