Compare and contrast the animals' situation at Manor Farm and their situation at Animal Farm.Explain the differences and similarities between the...

There's really not much difference between the way things were under Farmer Jones and the way they are at the end of the book.  That's pretty much the point of the book and the point of part in Chapter X where Napoleon tells Pilkington and the other people that the name of the farm is being changed back to Manor Farm.

Here's one other way that Orwell shows the similarities: in Chapter I, he has Old Major say this:

You, Boxer, the very day that those great muscles of
yours lose their power, Jones will sell you to the knacker, who will cut
your throat and boil you down for the foxhounds.

Think about what ends up happening to Boxer.  It is exactly this fate.  He gets hurt in the fighting, he works himself until he is weak.  When he gets too weak, Napoleon sells him to the knackers.

A major theme of the book is the idea that things are no better under the pigs than they were under the humans.
