A project in Yuba County explores the use of red seaweed (Asparagopsis taxiformis) to reduce methane emissions in grazing cattle. Previous findings suggested a 90% reduction in methane in controlled settings.

Researchers are now investigating effective delivery methods on open rangelands, where cattle graze over large areas. Initial trials are assessing the palatability of a mineral supplement mixed with seaweed.

Future phases will measure consumption consistency, methane reduction, and livestock performance metrics. The study is supported by the California Department of Food and Agriculture.
