What is "brown swiss"

Brown Swiss is a North American breed of dairy cattle. It derives from the Alpine Braunvieh. After the Holstein Friesian, it has the second-highest annual milk yield, over per annum. The milk contains on average 4% butterfat and 3.5% protein, making their milk excellent for production of cheese. The Brown Swiss is known for a long gestation period, immense size, large furry ears, and an extremely docile temperament. Regardless, the Brown Swiss is quite a resilient breed of cattle; they are hardy and capable of subsisting with little care or feed.
