Pork Industry Input Guides US Swine Health Improvement Plan Forward

More than 250 producers, veterinarians, swine health officials, state pork association officials and others recently met as delegates to the US Swine Health Improvement Plan meeting in Bloomington, Minnesota. The delegation discussed and passed resolutions and standards to bring more clarity and definition to the project works toward its goal of becoming a full USDA program designed to safeguard, certify and improve animal health.

"We're very pleased with the great discussions and action that took place at the 2022 house of delegates meeting as we seek to move the program forward," said Tyler Holck, DVM, US SHIP senior program coordinator, Iowa State University. "We would like to see even more producers, live-animal marketers and packers across the country join their peers in participating as we seek to grow this program in the months and years ahead."

Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

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.
