New guidelines being implemented by the U.S. Food and Drug Administration – effective Jan. 1, 2017 - require label changes allowing only therapeutic uses of some medically important antimicrobial drugs, and call for increased veterinarian oversight for these drugs used in animal feed. The drugs are currently sold over the counter with unrestricted access. According to the Centers for Disease Control and Prevention, overuse may be related to the development of antibiotic-resistance-related infections, which kill 23,000 people and sicken millions each year.

Over the past few years, drought has negatively affected everyone in the state and ranchers are no exception. Due to the drought, most areas have seen a decline in forage production and water availability, and as a result many livestock producers reduced their herd sizes and grazing season.
With some recent forecasts bringing encouraging news about a potential El Niño, some ranchers have been asking about what they should expect in terms of forage production, if and when the rains come. What they want to know is how soon rangeland productivity will reach the pre-drought levels again. One issue that I always draw their attention to is the levels of residual dry matter (RDM) on the rangelands. Even with the reduction in...

Some of the best practices for maintaining healthy home gardens and landscapes also cut water use, a particularly important benefit during the drought. That's the case with compost. UC Agriculture and Natural Resources' environmental horticulture advisors and UC Master Gardeners have long encouraged Californians to liberally use compost to improve their soil.
“Adding compost to your soil on a regular basis increases the amount of water your soil can hold, therefore decreasing the amount of times you need to apply water to your landscape,” says Missy Gable, the director of the UC Master Gardener program, in...
Drought is decreasing but not defeating the pathogen that causes sudden oak death, according to a citizen science-assisted survey conducted this spring by a UC Agriculture and Natural Resources forest pathologist.
Results of the 2015 Sudden Oak Death Blitz survey reveal coastal mountain infestations in areas such as Big Sur (19% infection), the Santa Cruz Mountains (13% infection), and western Sonoma County (12% infection) remain high despite an overall decline in infection rates from 4.4% to 3.7% across California's 15 infested counties.
Sudden oak death (SOD) symptoms have been seen in Alameda, Contra Costa, Humboldt, Lake, Marin, Mendocino, Monterey, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano,...
Rangeland is where deer and antelope play. It is also home for grazing livestock and many other animals. “Almost half of the land on Earth is rangeland and one-third of the United States is rangeland,” the latest issue of Jr. Animal Scientist tells its young readers. A UC Agriculture and Natural Resources (UC ANR) advisor is among the scientists who contributed to the rangeland issue of the children's magazine.
Jr. Animal Scientist is published by the American Society of Animal Science for children aged 5 to 12 who are interested in animals. For the September 2015 issue, members of the Society for Range Management...
