WHAT IS A SKIN SKIN?
When a cow is killed, its skin will be taken away. It is then picked in its raw state, from the moment it is made salted. It is selected and manipulated by size and color.

Coat color is an important criterion in species specificity. such as the Holland (Holstein), which is black and white in color, the Jersey with yellowish-brown fur, the Hereford and Simmental cows, with the white face. The coat color is usually divided into six categories: white, red, black, brown, gray, white stripes and variants.

The white genetic mechanism consists of three types:

The dominant white gene WW: is white fur, ww is red fur, Ww is sand color (red sand), usually found in British short horned cows, Ww if carrying black B gene will be blue gray or called blue sand (above in fact a mix of black and white), under the sun it will look blue-gray.

In dairy cattle, dairy cattle, dairy cattle, the coat is mostly white with varying degrees of white, in white spots, the whole color is determined by the S gene and spot color. determined by the ss gene, the size of the spot color affected by the repair gene, the other form is the color of the hair on both sides of the body, the back and the belly (including the front of the chest) are white, hind legs are white like Hereford cows, the color is determined by the dominant SG gene, while the white fur on the face is defined by the dominant SH gene; S, SG, SH, s are alleles, between S, SG, SH do not dominate completely, but dominate s.

Normally, in the color of cowhide, black (B) dominates other colors; red (r) dives other colors. The usual white stripe (s) is dive with pure color, but predominates the following whites: white on Hereford cattle face, Simmental cow (SH), white on the white lower legs and abdomen , white in the Bel Bel Galloway Cows. Tiny black spots on the dominant skin (Ps), dark brown (tiger skin) diving (br); dominant hind legs with white hindquarters (Pe), pastel pink at tail eyes and dominant nose (Re). The color of the cow's coat is also associated with more than one pair of genes, and its dominance is also complex. Black (B) in Angus cattle dominates in red (b), and short horns in black and red (R) dominate in white (W), heterozygous in red spotted white cow, they will give birth to the next generation is red-haired cow (hung fur) and white-haired cow.
