Zakah on livestock kept in a pen for trade

Question:
The questioner, Abu 'Abdullah, says: Shaykh, I have livestock that I feed in a pen, consisting of goats, sheep, and rams, and I buy and sell them. Is there any zakah due on them?

Answer:
In themselves, there is no zakah due on them because they are not grazing freely, but they are trade goods, so you pay zakah on their value. You pay zakah on their value when the lunar year of possession is completed and they are still with you; you appraise them and pay zakah on that value. If you sell them, you pay zakah on their value. Yes.
