Context paragraphs:
Western Finncattle: Western Finncattle are a breed of cattle from western Finland.  They are a dual purpose breed, used in dairy and beef production.  These cattle are usually red and polled (hornless).

Sex-linked barring: Sex-linked barring is a plumage pattern on individual feathers in chickens, which is characterized by alternating pigmented and apigmented bars.  The pigmented bar can either contain red pigment (phaeomelanin) or black pigment (eumelanin) whereas the apigmented bar is always white.  The locus is therefore often referred to as an ‘eumelanin diluter’ or ‘melanin disruptor’.  Typical sex-linked barred breeds include the Barred Plymouth Rock, Delaware, Old English Crele Games as well as Coucou de Renne.

Jutland cattle: Jutland cattle are a rare Danish breed of cattle used in both dairy and beef production.  Bred from the indigenous cattle of Jutland the breed could be light grey, dark grey or black pied with upward curving horns.  The first herdbook published in 1881 had a small dairy type and a larger beef type.  The dairy cows were small, averaging 120 cm high and weighing 350 kg, producing between 800 and 1000 kg of milk per lactation.

Piebald: A piebald or pied animal is one that has a pattern of pigmented spots on an unpigmented (white) background of hair, feathers or scales.  The spots are pigmented in shades of black and/or yellow as determined by the genotype controlling the color of the animal.  The animal's skin underneath its coat may or may not be pigmented under the spots but the skin in the white background is not pigmented.

Gelbvieh: Gelbvieh (] , German for "yellow cattle") is a cattle breed originating in several Franconian districts of Bavaria, Germany in the mid-18th century.  Gelbvieh were originally known as “red-yellow Franconian cattle” and were developed from several local breeds.  Gelbviehs were originally bred to be triple purpose cattle (used for milk, beef, and draught), but the modern Gelbvieh is primarily used for beef production.

Northern Finncattle: Northern Finncattle are a dual breed of cattle from Finland, used in both dairy and beef production.  These cattle are usually white with pigmented ears and muzzle, and naturally polled.

Shorthorn: The Shorthorn breed of cattle originated in the North East of England in the late 18th century.  The breed was developed as dual-purpose, suitable for both dairy and beef production; however, certain blood lines within the breed always emphasised one quality or the other.  Over time, these different lines diverged, and by the second half of the 20th century, two separate breeds had developed – the Beef Shorthorn, and the Milking Shorthorn.  All Shorthorn cattle are coloured red, white, or roan, although roan cattle are preferred by some, and completely white animals are not common.  However, one type of Shorthorn has been bred to be consistently white – the Whitebred Shorthorn, which was developed to cross with black Galloway cattle to produce a popular blue roan crossbreed, the Blue Grey.

Beef Shorthorn: The Beef Shorthorn breed of cattle was developed from the Shorthorn breed in England and Scotland around 1820.  The Shorthorn was originally developed as a dual-purpose breed, suitable for both dairy and beef production.  However, different breeders opted to concentrate on one purpose rather than the other, and in 1958, the beef breeders started their own section of the herdbook.  Since then, the Beef Shorthorns have been developed as a separate breed to the Dairy Shorthorns.

South Devon cattle: South Devon cattle are a breed of British beef cattle.  They are the largest of the British native breeds, and are believed to have descended from the large red cattle of Normandy which were imported during the Norman invasion of England.  The breed is a rich, medium red with copper tints, though it varies in shade and can even appear slightly mottled.  The breed today is predominately used for beef production although it has been milked in the past.  The official governing body, The South Devon Herd Book Society was founded in 1891.

Brown Carpathian: The Brown Carpathian (Ukrainian: бypa кapпaтськa ) is a breed of cattle from Western Ukraine.  Found in the Trans-Carpathian region of Ukraine, the breed was the result of crossing Brown Swiss with the local cattle to produce a dual-purpose breed for dairy and beef production.  The breed was first recognized in 1972, and since the 1980s there have been further crossings with Brown Swiss and Jersey bulls.
