How life cycle assessment demonstrates the environmental benefits of optimizing amino acids in dairy cow diets

Adisseo Season 2 Episode 2

Research from France evaluated the cradle-to-farmgate environmental performance of dairy production using Life Cycle Assessment (LCA) calculations performed in the dairy module of the Animal Production Systems tool from Blonk Sustainability Tools.

A theoretical methionine-balanced diet was simulated by substituting mainly soybean meal (typically imported into France) with cereals relative to the control diet. The optimized methionine-balanced diet increased predicted dry matter intake, milk yield and milk composition.

Consequently, LCA parameters were affected, decreasing the impact in France on climate change, acidification, eutrophication and land use. This research shows that balancing diets for methionine improves cow performance and may reduce environmental impacts.

Based on 2022 American Dairy Science Association (ADSA) abstract: 

2220T Optimizing diets for metabolizable methionine may reduce dairy environmental impact.
