Future Pharma Factories

In the near future, traditional barnyard animals might also be small, organic pharaceutical factories. Some animals have already been genetically altered to produce pharmaceuticals, and their products are being tested by the Food and Drug Administration (FDA). Here are few examples of the possibilities:

1. a cow that produces milk containing lactoferrin, which can be used to treat human infections
   
2. a goat that produces milk containing antithrombin III, which can help prevent blood clotting in humans
   
3. a sheep that produces milk containing alpha- antitrypsin, which is used to treat cystic fibrosis.
