Evaluating Production MEtrics in Relation to Sustainability in a Wean-to-Finish Barn

Publish Date: June 8, 2023

Improving the sustainability of the United States' (US) pork supply chain requires a better understanding of the relationship between the environment and production practices. Pork producers play a crucial role in environmental stewardship, however, the impact of production efficiency on greenhouse gas (GHG) emission has not been well-established. Interpreting the influence of specific production metrics on GHG emission is essential for benchmarking and improving the environmental sustainability of the pork industry.

Sustainability in the Swine Industry: Understanding the Life Cycle Assessment of the Pork Supply Chai

Publish Date: April 1, 2022

The overarching goal of the swine industry is to provide high-quality protein to feed the world’s growing population. Improvements in production efficiency are continually being made to create a better and more sustainable product. Sustainability in the swine industry can be calculated using a Life Cycle Assessment (LCA). An LCA is a holistic approach to analyze the cumulative environmental impacts of the different phases of swine production. Swine production LCAs can inform producers and consumers how certain production practices impact the environment. The methodology of an LCA can be divided into four sections: goal and scope definition, inventory analysis, impact assessment, and interpretation.

Handling tools to move non-ambulatory pigs that comply with the Common Swine Industry Audit

Publish Date: September 23, 2019

A pig can become non-ambulatory anytime on-farm due to injury, illness or fatigue (Benjamin, 2005). Hence, caretakers may be required to move non-ambulatory pigs into or out of pens, alleys and load out areas. The National Pork Board provides guidance about humane swine handling of healthy and non-ambulatory pigs through their Pork Quality Assurance Plus and Transport Quality Assurance programs (NPB, 2019, 2017). This factsheet provides information related to handling tools that are options to move a non-ambulatory pig on-farm.
