The Scottish Highlands are the oldest registered breed in the world. The Highland breed is predominantly used for beef production, but can be milked. Their milk has a high butterfat content. Interestingly, a group of Highland cattle is not called a herd, but a 'fold' instead.
The Dexter breed originated in Ireland. Dexter cattle are about half the size of a traditional Hereford. Mature cows weigh 600–700 pounds (270–320 kg) and mature bulls weigh 1,000 pounds (450 kg). They may be of several solid colors, black being the most common, with horns. Dexters make excellent milk cows, producing 2 to 2.5 gallons (7.6 to 9.5 liters) per day, but they are also excellent meat producers.
