The dairy herds that supply AE milk are not treated with synthetic growth hormones, also known as rBST (recombinant bovine somatotropin) or rBGH (recombinant bovine growth hormone).* Every ounce of our milk is tested rigorously before we accept it from the farm, and we do not accept milk with added hormones, antibiotics or pesticides. This information is also included on our gallon and half-gallon cartons.
*No significant difference has been shown between milk derived from rBST/rBGH treated and non-rBST/rBGH treated cows.
