Why were cattle useful animals for farmers to domesticate?

Some reasons:

→ They're cheap and common animals.

→ They can be either a source of meat, skin (leather) or milk.

→ Farmers benefit a lot with them, since what they produce are things of everyday consumption.

→ You don't need to spend much to be able to have them (mostly only with land).
