Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of cells and of DNA fragments.
The Jersey is a British breed of small dairy cattle from Jersey, in the British Channel Islands. It is one of three Channel Island cattle breeds, the others being the Alderney – now extinct – and the Guernsey. The milk is high in butterfat and has a characteristic yellowish tinge.
The Holstein Friesian is an international breed or group of breeds of dairy cattle. It originated in the Dutch provinces of North Holland and Friesland and in Schleswig-Holstein in northern Germany. It is the dominant breed in industrial dairy farming worldwide, and is found in more than 160 countries. It is known by many names, among them Holstein, Friesian and Black and White.
Dairy farming is a class of agriculture for long-term production of milk, which is processed for eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including rotary parlors, the milking pipeline, and automatic milking systems that were commercially developed in the early 1990s.
The Guernsey is a breed of dairy cattle from the island of Guernsey in the Channel Islands. It is fawn or red and white in colour, and is hardy and docile. Its milk is rich in flavour, high in fat and protein, and has a golden-yellow tinge due to its high β-carotene content. The Guernsey is one of three Channel Island cattle breeds, the others being the Alderney – now extinct – and the Jersey.
Dairy cattle are cattle bred for the ability to produce large quantities of milk, from which dairy products are made. Dairy cattle generally are of the species Bos taurus.
The Dairy Shorthorn is a British breed of dairy cattle. It derives from the Shorthorn cattle of Tees-side, in the North Riding of Yorkshire and in Northumbria in north-eastern England. The Shorthorn was for this reason at first known as the Durham or Teeswater.
The Brown Swiss or American Brown Swiss is an American breed of dairy cattle. It derives from the traditional triple-purpose Braunvieh of the Alpine region of Europe, but has diverged substantially from it. It was selectively bred for dairy qualities only, and its draft and beef capabilities were lost. Milk yield was measured in 2013 at 10231 kg (22600 lb) per year; the milk has about 4% butterfat and 3.5% protein and is suitable for making cheese.
Commercial animal cloning is the cloning of animals for commercial purposes, currently, including livestock, competition camels and horses, pets, medical uses, endangered and extinct animals, as first demonstrated in 1996 for Dolly the sheep.
The Randall Lineback or Randall is an American breed of cattle. It originated in Bennington County, Vermont, and is critically endangered.
Ubre Blanca was a cow in Cuba known for her prodigious milk production. The cow, along with the "Cordón de La Habana" coffee plantations, the Voisin pasture system, and the microjet irrigation system, symbolizes Fidel Castro's efforts to modernize Cuba's agricultural economy. The Spanish phrase ubre blanca translates to the English phrase "white udder."
Red Sindhi cattle are the most popular of all Zebu dairy breeds. The breed originated in the Sindh province of Pakistan, they are widely kept for milk production across Pakistan, India, Bangladesh, Sri Lanka, and other countries. Their milk production is about 12 to 15 kg per day They have been used for crossbreeding with temperate (European) origin dairy breeds in many countries to combine their tropical adaptations with the higher milk production found in temperate regions. It has been crossed with Jerseys in many places, including India, the United States, Australia, Sri Lanka, etc.
The Australian Friesian Sahiwal, is an Australian breed of dairy cattle whose development commenced in the 1960s by the Queensland Government. It is a combination of the Sahiwal, a dairy breed of Bos indicus from Pakistan and Holstein breeds, designed for the tropical regions of Australia. Cows produce approximately 3,000 litres of milk per lactation under tropical pasture conditions with a high resistance to heat, humidity, ticks and other parasites.
Jamaica Hope is a dairy breed of cattle originating from Hope Farm in Jamaica.
The goat or domestic goat is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago.
Norwegian Red is a breed of dairy cattle developed in Norway since 1935. Since the 1970s, breeders strongly emphasized functional and production traits resulting in excellent production combined with world-leading performance in health and fertility traits. Norwegian Red cows can have either a red and white or black coat and have a high proportion of genetically polled animals.
Genetically modified mammals are mammals that have been genetically engineered. They are an important category of genetically modified organisms. The majority of research involving genetically modified mammals involves mice with attempts to produce knockout animals in other mammalian species limited by the inability to derive and stably culture embryonic stem cells.
Cattle are large, domesticated, cloven-hooved herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus Bos. Adult female cattle are referred to as cows and adult male cattle are referred to as bulls. Colloquially, young female cattle (heifers), young male cattle (bullocks) and castrated male cattle (steers) are also referred to as "cows".
Central Institute for Research on Buffaloes, Hisar, a publicly funded, institute for water buffalo research. It is located 170 kilometres (110 mi) from Delhi, at Hisar in the north Indian state of Haryana. It has a sub-campus, Bir Dosanjh, at Nabha. CIRB operates a nationwide network of 10 research centres working on breed improvement of the 7 main native breeds. CIRB, with over 20 laboratories for buffalo research, is the world's largest buffalo research institute with the widest range of breeds under study. With the aim of improving breeds and dissemination of information, CIRB has sold over 1,000 bulls, conducted ~200,000 artificial insemination in the field for the farmers' buffaloes with a 41% conception rate, distributed ~520,000 progeny tested frozen semen kits to 45,000 farmers and over 250 institutes, imparted training to several thousand farmers on advanced buffalo husbandry, and created the world's first online Buffalopedia in several languages. It has a large research partner network across India and the globe. It is the second institute to successfully clone a buffalo in 2016, after the first successful cloning was achieved by the National Dairy Research Institute, Karnal in 2010. In July 2017, the Indian Council of Agricultural Research ranked CIRB Hisar as India's number one Buffalo research institute for the year 2016–17.
Dairy plays a significant part in numerous aspects of Indian society, including cuisine, religion, culture, and the economy.
