Natural Feed Reduces Livestock GHGs
Since 1990, distillers dried grains with solubles and synthetic amino acids have replaced soybeans and corn in livestock feed. This trend impacts lifecycle greenhouse gas emissions from livestock production, in addition to family farm revenue. A 2020 Argonne laboratory study found greenhouse gases and carbon intensity are significantly higher with synthetic feed compared to natural ingredients. This finding matters to sustainability managers because about 90% of GHG emissions from pigs and poultry come from producing the feed.
