An international project is underway in Europe to prove the effectiveness of grass-fed cattle and its benefits for the environment. Cattle farmers in Germany, Italy, Sweden, and the UK are experimenting with feeding cows solely or mostly grass, reducing the need for imported grains that contribute to greenhouse gas emissions and deforestation. The project involves 31 partners across 12 countries and aims to collect data and develop tools for improving animal welfare and product quality in grass-fed farming practices.
