I deal with cattle and sheep.

Answer

Zakaat is paid on animals which graze on natural pastures for more than six months. Also if the animals are kept for breeding and milking, then Zakaat is payable.

There is no Zakaat on animals which are fed for six months. Animals procured for trading are regarded as stock-in-trade. Zakaat is paid on the value of such animals. Cattle and sheep have different Nisaabs. Zakaat is not payable on less than 30 cattle and less that 40 sheep.
