The average cashmere can produce about four ounces of cashmere a year. How much you get paid for it will depend on if it is raw or processed. For contrast, an angora goat will produce from eleven to seventeen pounds of mohair in a year. Hope that helps, I'm not sure what the market value of mohair and cashmere is right now, but my bets are that the angoras produce so much more than cashmeres that they may be more profitable. Cashmeres, though, are hardier so may cost less in upkeep, especially since I hear that angoras are not as cold tolerant.
