popular breed of dairy goat originating in the Saanen Valley of Switzerland. The coat of the Saanen is fine and light-coloured, with white being generally preferred. In build it is similar to the Toggenburg, with smallish frame, straight or dished face, and erect ears. As is that of other goats, milk of the Saanen is whiter and more easily digestible than cow's milk. The breed is highly valued in Europe and the United States as an even, persistent producer.
