I want to buy Beetal for milk.

Beetal is a good milk goat for you. Buy a healthy doe that has kidded at least once, and preferably in her second or third lactation. Check that both teats work, she is active, and there is no cough or nasal discharge. Milk yield is usually around two to two point two five liters per day. If you want, I can help you shortlist the right age and price range.
