GERMANY, Essen. A comparative life cycle assessment (LCA) by Evonik has further demonstrated the ecological advantages of using its feed amino acids and feeding concepts compared with common animal nutrition practices.
The Animal Nutrition business line is part of the company's life sciences division Nutrition & Care, which is all about developing sustainable solutions for a better life for people and animals.
The global LCA analyzed the environmental impact of feeding swine, broiler chickens, and laying hens. The study was audited and certified by TÜV Rheinland according to ISO 14040 and 14044 in second quarter 2021. In 2010, Evonik pioneered its first TÜV-certified comparative LCA for feed supplementation with the essential amino acids methionine, lysine, threonine, and tryptophan. In 2015, a second followed, which also included valine. Both times, feeds without amino acid supplementation served as a comparison.
In the new LCA, the environmental impact of species, and the developmentally appropriate feeding of swine, broiler chickens, and laying hens with balanced amino acid profiles and low crude protein content, was evaluated according to the following criteria: global warming, acidification and eutrophication potential; blue water consumption; land occupation; and respiratory inorganics. The analysis included feed raw material production, animal husbandry, and manure treatment emissions.
The study also demonstrates another advantage of low protein feeding regimes: the option to use regional raw materials with a lower environmental footprint.
