...similar controversy has blown up over CR's condemnation of bovine somatotropin (bst), a genetically engineered hormone to increase milk production in cows. Again, the magazine's original warning in the May 1992 issue (udder insanity) was widely reprinted, prompting consumer resistance to the use of bst on dairy cows. And again, a small battalion of other environmental watchdogs refuted the claims of danger, including the A.M.A. and the Food and Drug Administration...
...wrangling threatens the safety of American milk. The hormone, a natural protein found in cows, is being artificially manufactured in vats of genetically altered bacteria. When cows are regularly given extra doses of the hormone, their milk production can rise as much as 15%. Scientists call the chemical bovine somatotropin (BST) or, more simply, bovine growth hormone (BGH), and it is marketed under the trade name Posilac...
...substance at the center of the dispute is a naturally occurring protein known to scientists as bovine somatotropin, or more simply, bovine growth hormone (BGH). Dairy farmers have known for decades that cows given booster shots of BGH would produce more milk -- up to 15% more. But the only available source of the hormone was the pituitary glands of butchered cows, which yield only minute quantities. Then, in 1982, scientists used new gene-splicing techniques to manipulate bacteria into mass-producing BGH. By the mid-1980s, four drug companies -- including Monsanto and Eli Lilly -- had applied...
