What was the new policy? how can u find the idea against animalism?

The animals work sixty-hour weeks all spring and summer in order to build the windmill, but none begrudges the extra labor. In August, Napoleon instates “strictly voluntary” labor on Sundays: animals may choose not to come, but they will have their rations reduced by half. Napoleon opens trade, using money, with the neighboring farms and says that the animals may need to sell some of the hens’ eggs in the nearby town of Willingdon. Animalism was all about cooporation between all animals. No animal was to be "above" another one: work and rest was shared by all. Old Major had pointed out that animals were not to have anything to do with humans.
