The milk disappears in Chapter II, and the animals discover what happens to it in the next chapter. It is revealed that the milk is mixed each day into the pigs' mash. When the animals wonder why the pigs are receiving this privilege, Squealer argues that the pigs, because they are the brains behind the farm, need the extra nutrition found in the milk and apples, which, he claims, is scientifically proven to be essential for pigs. He even says that some of the pigs don't like milk and apples, but eat them for the benefit of all the animals. What this foreshadows is that the pigs, contrary to their rhetoric about the equality of all animals, are going to reserve certain privileges for themselves. They have no intent of creating true equality on the farm. This is the first example of the corruption of the principles of the revolution, which will eventually disintegrate into a totalitarian nightmare in which the pigs are no better than the humans.
