Findings offer solution for more climate-friendly cattle farming
Seaweed is once again showing promise for making cattle farming more sustainable. A new study by researchers at the University of California, Davis, found that feeding grazing beef cattle a seaweed supplement in pellet form reduced their methane emissions by almost 40% without affecting their health or weight. The study was published Dec. 2 in Proceedings of the National Academy of Sciences.
This is the first study to test seaweed on grazing beef cattle in the world. It follows previous studies that showed seaweed cut methane emissions

Conventional breeding of cattle over decades has resulted in significant positive impacts for dairies and the environment. With genomics, the future looks still brighter.
For the most part, dairy operators select cattle for breeding that have the highest genetic potential for milk production, health, structural soundness and fertility. The introduction in the 1940s of artificial insemination from bulls that were proven to father productive daughters resulted in dramatic changes to the industry, according to geneticist Alison Van Eenennaam, UC Cooperative Extension specialist with UC Agriculture and Natural Resources.
