Uses in agriculture
"In 1937 scientists observed that milk yield increased when BST was administered
to lactating cows. From the '30s through the early '80s, knowledge on chemical
structure, function and activity of ST from several animal species increased.
Supplies of ST were limited during this period to what could be extracted from
the pituitary glands of slaughtered animals ."
Monsanto developed a recombinant version of rBST, which goes by the brand name
POSILAC?. Growth hormones associated with injections given to dairy cows to
increase milk production are known under an assortment of terms, but these terms
generally refer to the same Monsanto product sold under this brand name.
Injected into dairy cattle, the product can increase milk production by an
average of more than 10% over the span of a lactation.
