Feeding grazing cattle seaweed cuts methane emissions by almost 40 percent

  • Findings offer solution for more climate-friendly cattle farming

University of California – Davis

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 percent without affecting their health or weight. The study was published December 2, 2024 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 82% in feedlot cattle and over 50% in dairy cows.

How much methane do cattle produce?

Livestock account for 14.5 percent of global greenhouse gas emissions, with the largest portion coming from methane that cattle release when they burp. Grazing cattle also produce more methane than feedlot cattle or dairy cows because they eat more fiber from grass. In the US, there are nine million dairy cows and over 64 million beef cattle.

“Beef cattle spend only about three months in feedlots and spend most of their lives grazing on pasture and producing methane,” said senior author Ermias Kebreab, professor in the department of animal science. “We need to make this seaweed additive or any feed additive more accessible to grazing cattle to make cattle farming more sustainable while meeting the global demand for meat.”

Difficulty in lowering grazing cattle emissions

Kebreab said that daily feeding of pasture-based cattle is more difficult than feedlot or dairy cows because they often graze far from ranches for long periods. However, during the winter or when grass is scarce, ranchers often supplement their diet.

For this study, researchers divided 24 beef steers (a mix of Angus and Wagyu breeds) into two groups: one received the seaweed supplement, and the other did not. Researchers conducted the 10-week experiment at a ranch in Dillon, Montana. Since these were grazing cattle, they ate the supplement voluntarily, which still resulted in a nearly 40 percent cut in emissions.

Most research to reduce methane emissions using feed additives have taken place in controlled environments with daily supplements. But Kebreab noted in the study that fewer than half of those methods are effective for grazing cattle.

“This method paves the way to make a seaweed supplement easily available to grazing animals,” said Kebreab. “Ranchers could even introduce the seaweed through a lick block for their cattle.”

Kebreab said pastoral farming, which includes large grazing systems, supports millions of people around the world, often in areas vulnerable to climate change. This study suggests a way to make cattle grazing better for the environment and play a role in fighting climate change.

related article in the same PNAS issue highlights the need to improve the efficiency of livestock production in low- and middle-income countries using better genetics, feeding and health practices. UC Davis Professor and Cooperative Extension Specialist Alison Van Eenennaam, the article’s author, said it is the most promising approach to meet the global demand for meat while limiting greenhouse gas emissions.

Other authors of the seaweed study include UC Davis postdoctoral researchers Paulo de Méo Filho Paulo Meo-Filho and John-Fredy Ramirez-Agudelo. The research was supported by Matador Ranch in Dillon, Montana.
