Why would domesticated animals be especially helpful to nomads?

1. They people who do nomadic herding do not have to face the task of going hunting everyday inorder to find food. Instead they can herd a lot of animals and use some of them or products from them to feed themselves.

2. Nomadic herding also gives the nomadic herders more time to spare in their hands, since they do not have to go searching for food 24x7.
