The Simmental or Swiss Fleckvieh is a Swiss breed of dual-purpose cattle. It is named after the Simmental – the valley of the Simme river – in the Bernese Oberland, in the canton of Bern in Switzerland. It is reddish in colour with white markings, and is raised for both milk and meat.
The average Simmental cow produces around 23,000 pounds of milk, or 2,674 gallons, of milk each lactation. With a standard lactation lasting 305 days, that comes out to 75 pounds, or almost 9 gallons of milk per cow per day.
