Feeding Grazing Cattle Seaweed Cuts Methane Emissions by Almost 40%

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 today (Dec. 2) in Proceedings of the National Academy of Sciences.

Can CRISPR Cut Methane Emissions From Cow Guts?

University of California, Davis, scientists are teaming up with UC Berkeley and UC San Francisco researchers on a $70-million donor-funded initiative that aims in part to cut climate change-causing emissions from cattle by using the genome-editing tool CRISPR on microbes in the cows’ gut.

Ph.D. Student Develops AI Platform for Dairy Farmers

Catie McVey wants to bring big data to the small farmer.

The Ph.D. candidate in animal biology at UC Davis has developed a customizable artificial intelligence platform called DairyFit to help dairy farmers get a better sense of what is happening in their herds.

McVey combined biostatistics and machine learning into an algorithmic platform where farmers can visualize data that is already being captured and analyze it to look for insights into behavior.

Understanding cattle personality may help keep rangeland productive, sustainable

Do you ever wonder why sometimes one, lone cow stands munching grass on a hillside while her fellow cattle graze in groups below?

Animal behavior experts at UC Davis do, and their curiosity may shed light on one of the most critical economic and ecological questions in rangeland management. How can we encourage more cattle to roam?

Genome-Edited Bull Passes on Hornless Trait to Calves

Study Sheds Light on Future of Genome Editing in Livestock

For the past two years, researchers at the University of California, Davis, have been studying six offspring of a dairy bull, genome-edited to prevent it from growing horns. This technology has been proposed as an alternative to dehorning, a common management practice performed to protect other cattle and human handlers from injuries.

UC Davis to lead national cow genomics effort

USDA-funded project aims to uncover important genetic traits in cattle

The cattle industry is the largest agricultural commodity in the United States, generating more than $100 billion in farm cash receipts in 2016. Despite cattle’s economic importance, scientists still have a long way to go to fully understand mechanisms that govern important genetic traits in the animals such as growth and disease resistance.

Can seaweed cut methane emissions on dairies?

Expert sees dramatic reduction when cows consume seaweed supplement

Seaweed may be the super food dairy cattle need to reduce the amount of methane they burp into the atmosphere. Early results from novel research at the University of California, Davis, indicate that just a touch of the ocean algae in cattle feed could dramatically cut greenhouse gas emissions from California’s 1.8 million dairy cows.

UC Davis Field Days

Farmers gather to see new research in beef, alfalfa and small grains

When it comes to agricultural research, there’s nothing like seeing it in action to learn how it fits on your farm. That’s why farmers, ranchers, crop advisers and many others gathered at UC Davis on a recent sunny day in May to attend field days focused on beef, alfalfa and small grains.
