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...
Whole herds of dairy cows are now being injected with a genetically engineered growth hormone (BST) so that they will produce more milk than ordinary cattle. Companies such as Monsanto and Calgene are set to market bioengineered plant products, including tomatoes that ripen without rotting. And researchers are talking about drought-tolerant grass that would need almost no mowing...

Protests have already greeted the likely approval by the U.S. Food and Drug Administration of biotechnology's first major agricultural product, a natural hormone called BST, which can be mass-produced in genetically altered bacteria.

Moreover, some opponents question the safety of milk from cows with extra BST...
