California’s Dairy Industry Has Grown Kinder to the Environment

California’s Dairy Industry Has Grown Kinder to the Environment

Milk is big business in California. It’s the agricultural product that brings in more farm revenue than any other in the state. It employs about 190,000 workers, and involves 1.78 million cows. Indeed, dairy has been important to California’s economy for decades, and over time innovations in animal husbandry, feeding and in growing crops that dairy cows eat have led to substantial changes in greenhouse gas emissions. Recently, Ermias Kebreab and his colleagues at the University of California, Davis, calculated exactly how much these emissions have changed in the 50 years from 1964 to 2014. Although the total emissions from the state’s dairy industry increased over that period, the state also produced much more milk, and the industry has become more efficient in terms of its emissions.

Developing a Better Cattle Reference Genome

Developing a Better Cattle Reference Genome

Cows are one of our major domestic animals, with about 1.4 billion domesticated cattle being raised for meat and dairy all over the world. Humans have long drawn from the existing genetic variation in cattle populations to select a variety of breeds with useful traits. The sequencing of the cattle genome enhanced the selection of cattle by allowing the use of genomic tools to select traits. Read More...
