It kills most of the bacteria, extending shelf life and reducing bacteria to safe levels. This is more effectively accomplished by boiling, but this has both cost and taste repercussions making pasteurization a reasonable middle ground between killing off unwanted organisms and maintaining the taste and integrity of the milk.

I really can not think of one disadvantage to Pasteurizing milk. Taste?
There is no such thing as regular milk. Milk is either whole or separated and can be pasteurized or non pasteurised. Better to go to the feed store and get powdered milk for calves. It usually has other additives to help the calf get stronger.
Louis Pasteur, who else?
Regardless of treatment/origin it's always better to boil milk.
Yoghurt is made from pasteurised milk to get rid of any harmful bacteria
