Pasiega Cattle
The Pasiega is a traditional Spanish breed of red dairy cattle from the autonomous community of Cantabria in northern Spain. It originated in the Valles Pasiegos in south-eastern Cantabria. The name derives from that of the Pas River, which flows through that region. Because of the colour of its coat it may also be known as the Roja Pasiega or Rojina. The Pasiega was believed to be extinct until the late twentieth century, when a surviving group was identified. The breed was officially recognised in 2007. It is one of only two autochthonous Spanish breeds of dairy cattle, the other being the Menorquina of Menorca in the Balearic Islands. History The Pasiega is a traditional dairy breed of Cantabria, and particularly of the area of the three principal towns of the Valles Pasiegos: San Pedro del Romeral, San Roque de Riomiera and Vega de Pas. Genetic studies have found it to be closely related to the Asturiana de la Montaña, Asturiana de los Valles, Rubia Gallega and Saya ...

Rubia Gallega
The Rubia Gallega, gl, Rubia Galega, italic=no, is a breed of cattle native to the autonomous community of Galicia in north-western Spain. It is raised mainly for meat. It is distributed throughout Galicia, with about 75% of the population concentrated in the province of Lugo. The coat may be red-blond, wheaten, or cinnamon-coloured. History A herdbook was established in 1933. In the 20th century, some crossbreeding occurred with the Portuguese Barrosã, Swiss Braunvieh, Simmental, and British Shorthorn breeds. At the end of 2015, the total registered Rubia Gallega population was 39,971, of which almost all were in Galicia. The breed is distributed throughout the autonomous community, with about 75% of the population concentrated in Lugo. It is found particularly at altitudes above about in the mountainous areas in the northern part of the province, including the , the , and the .

Artificial Insemination
Artificial insemination is the deliberate introduction of sperm into a female's cervix or uterine cavity for the purpose of achieving a pregnancy through in vivo fertilization by means other than sexual intercourse. It is a fertility treatment for humans, and is common practice in animal breeding, including dairy cattle (see Frozen bovine semen) and pigs. Artificial insemination may employ assisted reproductive technology, sperm donation and animal husbandry techniques. Artificial insemination techniques available include intracervical insemination (ICI) and intrauterine insemination (IUI). Humans History The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge. The case was reporte ...

Semen
Semen, also known as seminal fluid, is an organic bodily fluid created to contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the female ovum. Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen from the urethral orifice is called ejaculation. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". The fluid is designed to be discharged deep into the vagina, so the spermatozoa can pass into the uterus and form a zygote with an egg. Semen is also a form of genetic material. In animals, semen has been collected for cryoconservation. Cryoconservation of animal genetic resources is a practice that call ...

Herd-book
A breed registry, also known as a herdbook, studbook or register, in animal husbandry and the hobby of animal fancy, is an official list of animals within a specific breed whose parents are known. Animals are usually registered by their breeders while they are young. The terms studbook and register are also used to refer to lists of male animals "standing at stud", that is, those animals actively breeding, as opposed to every known specimen of that breed. Such registries usually issue certificates for each recorded animal, called a pedigree, pedigreed animal documentation, or most commonly, an animal's "papers". Registration papers may consist of a simple certificate or a listing of ancestors in the animal's background, sometimes with a chart showing the lineage. Types of registries There are breed registries and breed clubs for several species of animal, such as dogs, horses, cows and cats. The US ''Association of Zoos and Aquariums'' (AZA) also maintains stud books for captive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breed Society
Breed clubs are associations or clubs with activities centered on a single, specific breed of a particular species of domesticated animal. The purpose of the association will vary with the species of animal and the goals and needs of the members of the association. Breed associations or clubs may vary in their goals, activities and nomenclature from country to country, even for the same breed. Most domesticated animals, whether they are agricultural animals such as cattle, llamas, poultry, sheep and pigs, or companion animals such as pigeons, horses, cats and dogs, have breed clubs associated with the breed. Purpose In general, breed clubs and associations create a written definition of the breed (called a breed standard) for the breed with which the organization is associated. Breed clubs also maintain important records, and provide members with information. Many breed associations also have a social component, organising various activities such as shows. In addition, they may r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-breeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. ''Crossbreeding'', sometimes called "designer crossbreeding", is the process of breeding such an organism, While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ' ...

Friesian (cattle)
Holstein Friesians (often shortened to Holsteins in North America, while the term Friesians is often used in the UK and Ireland) are a breed of dairy cattle that originated in the Dutch provinces of North Holland and Friesland, and Schleswig-Holstein in Northern Germany. They are known as the world's highest-producing dairy animals. Dutch and German breeders developed the breed with the goal of producing animals that could most efficiently use grass, the area's most abundant resource, as their food. Over the centuries, the result was a high-producing, black-and-white dairy cow. The Holstein-Friesian is the most widespread cattle breed in the world; it is found in more than 150 countries. With the growth of the New World, a demand for milk developed in North America and South America, and dairy breeders in those regions at first imported their livestock from the Netherlands. However, after about 8,800 Friesians ( black pied German cows) had been imported, Europe stopped exporting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braunvieh
The Braunvieh ( German, "brown cattle") or Swiss Brown is a breed or group of breeds of domestic cattle originating in Switzerland and distributed throughout the Alpine region. It falls within the "Brown Mountain" group of cattle breeds. The Swiss Braunvieh was originally a triple-purpose animal, used for milk production, for meat and for draught work; the modern Braunvieh is predominantly a dairy breed. In the latter part of the nineteenth century cattle of this type were exported to the United States, where they were selectively bred for dairy qualities only, and developed into a distinct breed, the American Brown Swiss. From about 1960 the Braunvieh was extensively cross-bred with these American cattle, such that over 75% of the genetic make-up of the Swiss Braunvieh is from the American breed. Small numbers of the original breed, unaffected by cross-breeding, are registered as Original Schweizer Braunvieh or Original Braunvieh. History The Braunvieh derives from the gre ...

Butterfat
Butterfat or milkfat is the fatty portion of milk. Milk and cream are often sold according to the amount of butterfat they contain. Composition Butterfat is mainly composed of triglycerides. Each triglyceride contains three fatty acids. Butterfat triglycerides contain the following amounts of fatty acids (by mass fraction):The quote values vary by 1–3% according to the source: Butterfat contains about 3% trans fat, which is slightly less than 0.5 grams per US tablespoon. Trans fats occur naturally in meat and milk from ruminants. The predominant kind of trans fat found in milk is vaccenic fatty acid. Trans fats may be also found in some industrially produced foods, such as shortenings obtained by hydrogenation of vegetable oils. In light of recognized scientific evidence, nutritional authorities consider all trans fats equally harmful for health and recommend that their consumption be reduced to trace amounts. However, two Canadian studies have shown that vaccenic acid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urbanisation
Urbanization (or urbanisation) refers to the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized. That is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia. Notably, the United Nations has also recently projected that nearly all globa ...

Cordillera Cantábrica
The Cantabrian Mountains or Cantabrian Range ( es, Cordillera Cantábrica) are one of the main systems of mountain ranges in Spain. They stretch for over 300 km (180 miles) across northern Spain, from the western limit of the Pyrenees to the Galician Massif in Galicia (Spain), Galicia, along the coast of the Cantabrian Sea. Their easternmost end meets the Sistema Ibérico. These mountains are a distinct physiographic province of the larger Alpide belt, Alpine System physiographic division. The Cantabrian Mountains offer a wide range of trails for hiking, as well as many challenging climbing routes. Skiing is possible in the ski resorts of Alto Campoo, Valgrande-Pajares, Fuentes de Invierno, San Isidro, Leitariegos and Manzaneda. Geography The Cantabrian Mountains stretch east-west, nearly parallel to the Cantabrian Sea, as far as the pass of Leitariegos, also extending south between León (province), León and Galicia.
