البط

Most domestic ducks have their origins in mallards (Anas platyrhynchos) from which they were first domesticated in Southeast Asia at least 4,000 years ago. Their distribution is more localized than is that of chickens and they are far more numerous in areas with abundant water. They are particularly abundant in Bangladesh, China and Southeast Asia but are also popular in Egypt, Nigeria and much of Europe, particularly in western France. Breeds vary greatly depending on location and whether they are specialized for meat, egg or feather production or whether they are multipurpose. They are raised in a great variety of production systems ranging from small numbers of birds held in mixed farms, to vast flocks that are transported in lories to clear up paddy fields following rice harvests.
