With the exception of ground meats, it is not absolutely necessary to brown the meat before cooking it in a slow cooker or Crock Pot, although it is recommended as part of the flavor development of the dish. When meat is browned, the sugars and proteins on the surface undergo a change called the Maillard reaction, after the French physician Louis Camille Maillard (pronounced "My yard") who discovered the reaction. This reaction creates the rich nutty flavor associated with gravies, roasted meats, baked beans, and other foods.
If you don't brown the meat, particularly in beef dishes, then the final dish ends up tasting rather thin and without depth. In slow cooker recipes using chicken and pork, where the flavors are not usually so complex, browning is not as common. Still, the dishes may benefit from browning the meat.
Because ground meats are more prone to growth of e-coli and other bacteria, I would recommend always browning them.
