What is BST, rBST and/or artificial growth hormones?
Cows naturally produce BST, bovine somatotropin, a hormone that's associated with milk production. An artificial version of this hormone was developed called "rBST" (recombinant bovine somatotropin) that, when injected into cows, can increase milk production.
Why did Rosenberger's Dairy decide to request its farmers pledge not to use artificial growth hormones?
An increasing number of consumers are looking for milk that is free of artificial growth hormones. Rosenberger's Dairies requested that its farmers make this pledge to satisfy this demand.
Are all Rosenberger's Dairy products made from farmers who pledge not to use artificial growth hormones?
While consumer preference for milk free of rBST has increased, we are limited by available supply. At this time, only Rosenberger's white milk is processed by farmers who pledge not to use artificial growth hormones.
