California’s wine industry could play a role in reducing methane emissions from dairy cattle.

Researchers at University of California, Davis, added fresh grape pomace left over from winemaking operations to alfalfa-based feed for dairy cows and found that methane emissions were reduced by 10% to 11%. 

The preliminary findings could offer a low-cost sustainable pathway for vineyards to reduce waste while helping dairy operations maintain quality while cutting back on emissions of methane, which is a powerful greenhouse gas.

Not all cattle are the same when it comes to grazing. Some like to wander while others prefer to stay close to water and rest areas.

Recognizing those personality differences could help ranchers select herds that best meet grazing needs on rangelands, leading to better animal health and environmental conditions, according to a new paper from the University of California, Davis, published in the journal Applied Animal Behaviour Science.

Invasive plants can stay dormant for decades or even centuries after they have been introduced into an environment before rapidly expanding and wreaking ecological havoc, according to a new study led by the University of California, Davis.

The University of California, Davis, is leading the establishment of a new Integrative Center for Alternative Meat and Protein, or iCAMP. The center will work toward large-scale commercialization and technological advancement of alternative proteins, including cultivated meat (from animal cells grown in large fermentors), plant- and fungal-based foods, and innovative hybrids that combine conventional meat products with alternative proteins. 

Research led by University of California, Davis, sheds new light on how to access the sugars locked up in plant materials to convert byproducts into new feedstocks to produce fuels, materials and chemicals.

Converting grasses, weeds, wood and other plant residues into sustainable products normally produced using petroleum products will be key to achieving carbon neutrality.

“We want to utilize plant residues and there is a lot of plant waste out there,” said Tina Jeoh, a professor of biological and agricultural engineering at UC Davis.

Wild North American grapes are now less of a mystery after an international team of researchers led by the University of California, Davis, decoded and catalogued the genetic diversity of nine species of this valuable wine crop.

The research, published in the journal Genome Biology, uncovers critical traits that could accelerate grape breeding efforts, particularly in tackling challenges like climate change, saline environments and drought.

To manage johnsongrass, a noxious weed that crowds out cotton and sickens horses, farmers have tried herbicides, burning and hand-pulling. Now, researchers at University of California, Davis, have developed a more high-tech weapon against the invasive weed: artificial intelligence and machine learning.

Researchers at the University of California, Davis, have developed a web application to help farmers and industry workers use drones and other uncrewed aerial vehicles, or UAVs, to generate the best possible data. By helping farmers use resources more efficiently, this advancement could help them adapt to a world with a changing climate that needs to feed billions. 

Viruses in soil may not be as destructive to bacteria as once thought and could instead act like lawnmowers, culling older cells and giving space for new growth, according to research out of  University of California, Davis, published in the journal Nature Ecology & Evolution.

At first glance, Orobanche ramosa looks like an interesting blossoming plant, one that could add a unique flair to flower arrangements. But it’s a parasitic weed that attaches to roots, sucks out nutrients and is threatening California’s lucrative $1.5 billion processing tomato industry.
