• The process used to make bST is the basic process used to produce several products other than bST, such as human insulin, interferons, human and animal somatotropins, and rennet, a key product in cheese production.
  
  
• bST, like other milk proteins, is digested into amino acids when eaten. It is not orally active as it cannot be absorbed from the stomach as an intact molecule. bST is a protein that occurs naturally in milk. Giving cows POSILAC^® does not cause the level of bST already present in milk to change.
  
  
• bST does not stimulate growth in humans. It affects cows and certain other animals, thus being species-limited. This was demonstrated during the 1950s when researchers at Harvard University and other schools injected people with substantial amounts of bST as a possible cure for dwarfism. bST was shown not to cause people to grow or to otherwise affect their well-being. Scientists later learned only somatotropin from humans or other primates will stimulate growth in humans.
  
  
• The human safety of dairy and meat products from dairy cows receiving bovine somatotropin (rbST) supplements has been confirmed by over 50 countries. POSILAC has also been evaluated on dairy farms in many countries worldwide.
  
  
• All producers, regardless of herd size, can use POSILAC to increase the profitability of their herd. Milk production will increase an average of 10 pounds of milk per supplemented cow per day.
  
  
• The reproductive performance of cows supplemented with POSILAC is equal to that of unsupplemented cows of an equivalent production level.
