In a move towards more sustainable cattle farming, researchers at the University of California, Davis have developed a seaweed-based feed that reduces methane emissions from beef cattle by nearly 40%.
This study, noted in the Proceedings of the National Academy of Sciences, marks a step forward in addressing climate change through agricultural innovation.
"Ermias Kebreab, the study’s senior author, highlighted the challenge of making such feed additives accessible for pasture-based cattle, a critical step toward sustainability.
Grazing cattle, which form the bulk of beef production, produce more methane compared to their feedlot counterparts due to their high-fiber diet.
This new seaweed supplement, delivered in pellet form, offers a practical solution that could be easily integrated into daily feeding routines, especially during leaner winter months or in regions with scarce grass.
Implementing this strategy could significantly lower the carbon footprint of the beef industry. Kebreab suggests that making these additives widely available could transform the sector, making it both economically viable and environmentally friendly.
With global meat demand rising, this innovation not only addresses environmental concerns but also supports global food security.
The success of this study provides a hopeful outlook for reducing livestock emissions worldwide, especially in areas vulnerable to climate change, supporting millions of people dependent on pastoral farming.
As this technology develops, it could become a staple in environmental conservation efforts within the agriculture sector.
