American Aberdeen-Angus Breeders' Association
The American Angus is an American breed of beef cattle. It derives from the Scottish Aberdeen Angus population, but may only be black; red-coated individuals may not be registered with the American Angus Association, but can be registered as Red Angus. History Some stock of the Scottish Aberdeen Angus breed was exported to Montreal, Canada, in about 1859, but nothing more is known of it. The earliest import to the United States was in 1873, when a Scottish landowner named George Grant brought some to his settlement at Victoria, Kansas, where they were cross-bred with his Texas Longhorn stock. Further imports to the United States of some head were made from 1878 to 1883. In that year a breed association, the American Aberdeen-Angus Breeders' Association, was established with 60 members in Chicago, Illinois; the name was shortened to American Angus Association in the 1950s. Until 1917 both black and red cattle could be registered in the herdbook of the association. Thereaft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DAD-IS
DAD-IS is the acronym for the Domestic Animal Diversity Information System, a tool developed and maintained by the Food and Agriculture Organization of the United Nations as a part of its programme for management of animal genetic resources for food and agriculture. It includes a searchable database of information on animal breeds. Overview The FAO began to collect data on animal breeds in 1982. The first version of DAD-IS was launched in 1996 and the software has been updated several times; the fourth version was launched in 2017. DAD-IS includes a searchable database of information about animal breeds, the Global Databank for Animal Genetic Resources. It contains information on breed characteristics, uses, geographic distribution and demographics; more than images; and tools for generating user-defined reports; and has a multilingual interface and content. It also provides contact information for the national and regional coordinators for the programme. Data is collected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breed Association
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Vigor
Heterosis, hybrid vigor, or outbreeding enhancement is the improved or increased function of any biological quality in a Hybrid (biology), hybrid offspring. An offspring is heterotic if its trait (biology), traits are enhanced as a result of mixing the genetic contributions of its parents. The heterotic offspring often has traits that are more than the simple addition of the parents' traits, and can be explained by Mendelian inheritance, Mendelian or non-Mendelian inheritance. Typical heterotic/hybrid traits of interest in agriculture are higher yield, quicker maturity, stability, drought tolerance etc. Definitions In proposing the term heterosis to replace the older term heterozygosis, George Harrison Shull, G.H. Shull aimed to avoid limiting the term to the effects that can be explained by heterozygosity in Mendelian inheritance. Heterosis is often discussed as the opposite of inbreeding depression, although differences in these two concepts can be seen in evolutionary co ...

Black Baldy
The Black Baldy is a type of cross-bred beef cattle. It is traditionally produced by crossing Hereford bulls on Aberdeen Angus cows. These cattle are commonly reared in Australia and New Zealand. In North America, the term Black Whiteface is also used in some regions. Characteristics The Black Baldy is traditionally produced by crossing Hereford bulls on Angus cows. The reverse cross, of Angus bulls on Hereford heifers, may also be employed in an attempt to produce smaller calves and thus reduce dystocia during birth. The first-generation calves from this cross uniformly exhibit the three principal dominant traits of the parent breeds – the polled (hornless) characteristic and the black coat of the Angus, and the white face of the Hereford. If first-generation Black Baldies are then bred together, the resulting calves are highly variable. The skin is black, which in sunny climates can reduce the prevalence of sunburn on bare skin, such as the udder of the cow. Black ...

Hereford (cattle)
The Hereford is a British breed of beef cattle originally from Herefordshire in the West Midlands of England. It was the result of selective breeding from the mid-eighteenth century by a few families in Herefordshire, beginning some decades before the noted work of Robert Bakewell. It has spread to many countries; in 2023 the populations reported by 62 countries totalled over seven million head; populations of over were reported by Uruguay, Brazil and Chile. The breed reached Ireland in 1775, and a few went to Kentucky in the United States in 1817; the modern American Hereford derives from a herd established in 1840 in Albany, New York. It was present in Australia before 1850, and in Argentina from 1858. In the twenty-first century there are breed societies in those countries and in the Czech Republic, Denmark, Estonia, France, Hungary, the Netherlands, Norway, Portugal, Spain and Sweden in Europe; in Brazil, Chile, Paraguay and Uruguay in South America; in New Zealand; an ...

Crossbreeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. 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 ''crossbreed'' is uncommon, and no universal term is used to distinguish hybridization or crossing within a population from those between populations, or even those between species. Crossbreeding is the process of breeding such an organism. It can be beneficially used to maintain health and viability of organisms. However, irresponsible crossbre ...

Certification Mark
A certification mark on a commercial product or service is a registered Mark (sign), mark that enables its owner ("certification body") to certify that the goods or services of a particular provider (who is not the owner of the certification mark) have particular properties, e.g., regional or other origin, material, quality, accuracy, mode of manufacture, being produced by Trade union, union labor, etc. The standards to which the product is held are stipulated by the owner of the certification mark. There are essentially three general types of certification marks: # certifying that goods or services had originated in a particular geographic region (e.g., Roquefort cheese); # certifying that goods or services meet particular standards for quality, materials, methods of manufacturing, for example, tests by the Underwriter Laboratories; # certifying that the manufacturer has met certain standards or belong to a certain organization or union (e.g.,BIS Certification in clothing). ...

Beef
Beef is the culinary name for meat from cattle (''Bos taurus''). Beef can be prepared in various ways; Cut of beef, cuts are often used for steak, which can be cooked to varying degrees of doneness, while trimmings are often Ground beef, ground or minced, as found in most hamburgers. Beef contains protein, iron, and vitamin B12. Along with other kinds of red meat, high consumption is associated with an increased risk of colorectal cancer and coronary heart disease, especially when processed meat, processed. Beef has a high Environmental impact of meat production, environmental impact, being a primary driver of deforestation with the highest greenhouse gas emissions of any agricultural product.

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conse ...

Herdbook
A breed registry, also known as a herdbook, studbook or register, in animal husbandry, 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 ''European Association of Zoos and Aquaria'' (EAZA) and the US ''Association of Zoos and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Texas Longhorn
The Texas Longhorn is an American breed of beef cattle, characterized by its long horns, which can span more than from tip to tip. It derives from cattle brought from the Iberian Peninsula to the Americas by Spanish conquistadors from the time of the Second Voyage of Christopher Columbus until about 1512. For hundreds of years the cattle lived a semi-feral existence on the rangelands; they have a higher tolerance of heat and drought than most European breeds. The coat can be of any color or mix of colors; in some 40% of the cattle it is some shade of red, often a light red. In the twenty-first century, the Longhorn is considered a part of the cultural heritage of Texas. History The Texas Longhorn derives from cattle brought to the Americas by Spanish conquistadors from the time of the Second Voyage of Christopher Columbus until about 1512. The first cattle were landed in 1493 on the Caribbean island of La Isla Española (now known as Hispaniola) to provide food for ...
