April 23 (Bloomberg) -- The genetic blueprint of domestic cows has been decoded in a scientific feat that traces bovine evolution and may lead to more nutritious milk, meat and increased food supply, scientists reported.
A six-year effort by more than 300 researchers sequenced and analyzed the 22,000 genes of the bovine genetic code, which includes cell instructions for making milk and muscles, according to the research published online today in the journal Science. The genetic data also reveal how the cow’s four- chambered stomach digests and transforms grass forage into body tissues that make high-quality beef.
Understanding the biology and evolution of cows may lead to a revolution in cattle breeding, said study researchers in a statement. The key traits may be used to meet the need for affordable, sustainable nutrition, the authors said.
