In Animal Farm, what advantages are there for the animals in running their own farm?

We are given the answer
to this question inof this great novel. After the initial enthusiasm of having carried out the
revolution successfully, the animals at first experience many benefits to running their own
farm. Note howdescribes that first harvest:

All through
the summer the work of the farm went like clockwork. The animals were happy as they had never
conceived it possible to be. Every mouthful of food was an acute positive pleasure, now that it
was truly their own food, produced by themselves and for themselves, not doled out to them by a
grudging master. With the worthless parasitical human beings gone, there was more for everyone
to eat. There was more leisure too, inexperienced though the animals were.

Note then how well initially things work out, especially the
satisfaction with which the animals ate their own food that they had produced. Also note how
everyone worked:

But everyone worked according to his
capacity... Nobody stole, nobody grumbled over his rations, the quarrelling and biting and
jealousy which had been normal features of life in the old days had almost disappeared. Nobody
shirked...

This attitude is epitomised by , whose motto,
"Must work harder!", seems to help unite the animals in a common purpose as they all
work together to run the farm and get in the harvest. Of course, things do not stay like
this...
