The Genetic Aspects of Selective Breeding in Holstein Dairy Cattle

Holstein is the most common dairy variety in the world. They are genetically modified to produce higher yields which in turn will bring more benefit to the dairy industry. The first Holstein was born in Europe about 2000 years ago (1). They are from the Netherlands and the Friesland State in the northern part of the Netherlands. Crossing between black Batavia cow and white Frisian cow produces black and white cattle.

Among the main dairy products are Holstein Friesland, Brown Switzerland and Guernsey. Holstein - Freesian cows were originally from the Netherlands and Friesland. In North America, this cow is called a Holstein cow. Some of the features of Holstein are their black and white spotted bodies. These cows produce more milk than any other kind of cow. Brown Swiss cow originally came from Switzerland and is one of the oldest cow breeds. They are big, thick and tend to mature. Brown Swiss cows are usually light brown, dark brown and gray. They were brought to the United States around 1869. The last cow batch I will talk is Guernsey. They started in Alderney Island near the North Coast of France, Guernsey and Sark Island. They were imported to France around 1830. They are colored with medium sized white marks

Cows are their one purpose is to produce milk is a type of cow curtain. On average, they can produce 14,640 pounds of milk and 534 pounds of milk. Some of the more common cow breeds are Holstein cattle, air shear cheese, brown Swiss beef cheese, Guernsey beef cheese and jersey cow cheese. Holstein was born in the Netherlands and Ayrshire is from Scotland. The usual varieties of Holstein cows are the largest. Mature, mature cows have at least 1,500 pounds. Dairy cattle are an important part of Canada's exports. Beef cattle is a kind of cow's curtain, its main purpose is to produce human-consumed meat all over the world. Some of the main varieties are Angus, Charole and short horn. Angus is usually black and a poll. Charolais are white or creamy, short corners are red, white or a mixture of the two. Because these types of cattle adapt to better adapt to their climate, they produce more meat

Red and white cows are unique animals recognized by the pure blood cow society because they can be inherited from several different kinds of cows. Most red and white cows are Holstein cows, but there may be inheritance of other redhead cattle, such as milking short horn or Ayrshire. Red is not new to cattle. In fact, it is a natural mutation caused by the expression of recessive genes. Many Holstein breeders do not like red, so Red Bull and White Cow are excluded from registration. For this purpose, the Red and White Dairy Association was founded in 1964 by a group of short horn cattle breeders. To improve the production of short horn milk, Holstein has become a natural choice for its milking quality and natural red coat color.
