UC Davis to lead national cow genomics effort

June 21, 2018
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

May 23, 2018

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.

Isolating stem cells in cows

New findings could advance cattle production, help study human disease

For more than 35 years, scientists have tried to isolate embryonic stem cells in cows without much success. Under the right conditions, embryonic stem cells can grow indefinitely and make any other cell type or tissue, which has huge implications for creating genetically superior cows.

Keeping Cows Cool With Less Water and Energy

New Cooling Technologies Tested at UC Davis Dairy Facility

Innovative cooling technologies tested on dairy cows at the University of California, Davis, are addressing the long-standing challenge of keeping dairy cows cool in heat-stressed California.

Editing for a healthy future

February 27, 2017

New genetic technology enhances animal health, welfare

Gene editing — one of the newest and most promising tools of biotechnology — enables animal breeders to make beneficial genetic changes, without bringing along unwanted genetic changes.

And, following in the footsteps of traditional breeding, gene editing has tremendous potential to boost the sustainability of livestock production, while also enhancing food-animal health and welfare, argues animal scientist Alison Van Eenennaam of the University of California, Davis.

Breeding Hill-Climbing Cows

January 05, 2017

Genetic test could help improve management of California’s 38 million acres of rangeland.

Most of the 5 million cattle that graze on California’s rangelands like to dine in the valleys and hang out by creeks. This can lead to overgrazing in riparian areas and let perfectly good forage on hillsides go to waste.

But some cows are different. They prefer to climb hills and mountains and eat along the way. If more cattle followed the road less traveled, rangelands would be more productive and sustainable throughout California and the West.

Livestock and Climate Change

Facts and Fiction on Livestock and Climate Change

As the November 2015 Global Climate Change Conference COP21 concluded in Paris, 196 countries reached agreement on the reduction of fossil fuel use and emissions in the production and consumption of energy, even to the extent of potentially phasing out fossil fuels out entirely.
