Milk, in its human form, has been the foundation of nutrition for hominid infants for millions of years. In the past few millenia, animals have been domesticated for milk and meat. Many of them are ruminants, but not all are. The camel and the horse are notable exceptions, highly regarded in several cultures for their milk.
In the western world, kine (aka cattle), (Bos) are almost exclusively used for providing milk in useful quantities. As a matter of fact, in the United States this is such an important agricultural industry that entire sets of laws and price supports have been enacted.
This essay looks into the the issue of milk that is produced with Bovine Growth Hormone (BGH), (also called Bovine Somatotropin (BST))and will likely prove to be controversial. This is an important issue, and I will attempt to give it a fair treatment, but remember that many folks have already made up their minds without considering the actual data, and it is difficult to make folks who have already made decisions based on emotion to see logic. With that said, here we go.
