Ayrshire cattle (IPA /'??r??r/) are a breed of dairy cattle from Ayrshire in southwest Scotland. The adult Ayrshire cow weighs from 450 to 600 kilograms (990–1,320 lb). Ayrshires typically have red and white markings; the red can range from a shade of orange to a dark brown. They are known for their hardiness and their ability to convert grass into milk efficiently. The breed's strengths today are traits of easy calving and longevity (Wikipedia).
