Beefmaster
Beefmaster is a breed of beef cattle that was developed in the early 1930s by Tom Lasater (the breed founder), from a systematic crossing of Hereford cows and Shorthorn cows with Brahman bulls. The exact mixture of the foundation cattle is unknown, but is thought to be about 25% Hereford, 25% Milking Shorthorn and 50% Brahman. It was first recognized by the USDA as a new breed in 1954. The original intention was to produce cattle that could produce economically in the difficult environment of South Texas. The cattle were selected by using the Six Essentials – weight, conformation, milking ability, fertility, hardiness and disposition. While brownish-red is the most common color, the breed has no color standards. Over the past decade, the Beefmaster breed has become very popular among herd managers using the breed in their heterosis Heterosis, hybrid vigor, or outbreeding enhancement is the improved or increased function of any biological quality in a hybrid offspring.

Beef Cattle
Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of mature or almost mature cattle is mostly known as beef. In beef production there are three main stages: cow-calf operations, backgrounding, and feedlot operations. The production cycle of the animals starts at cow-calf operations; this operation is designed specifically to breed cows for their offspring. From here the calves are backgrounded for a feedlot. Animals grown specifically for the feedlot are known as feeder cattle, the goal of these animals is fattening. Animals not grown for a feedlot are typically female and are commonly known as replacement heifers. While the principal use of beef cattle is meat production, other uses include leather, and beef by-products used in candy, shampoo, cosmetics, and insulin. Calving and breeding Besides breeding to meet the demand for beef production, owners also use selective breeding to attain specific trai ...

Cattle Breeds
List of cattle breeds — Over 1000 breeds of cattle are recognized worldwide, some of which adapted to the local climate, others which were bred by humans for specialized uses. Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. ''Bos indicus'' (or '' Bos taurus indicus'') cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia. ''Bos taurus'' (or ''Bos taurus taurus''), typically referred to as "taurine" cattle, are generally adapted to cooler climates and include almost all cattle breeds originating from Europe and northern Asia. In some parts of the world further species of cattle are found (both as wild and domesticated animals), and some of these are related so closely to taurine and indicus cattle that interspecies hybrids have been bred. Examples include the Dwarf Lulu cattle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hereford (cattle)
The Hereford is a British breed of beef cattle originally from Herefordshire in the West Midlands of England. It has spread to many countries – there are more than five million purebred Hereford cattle in over fifty nations worldwide. The breed was first exported from Britain in 1817, initially to Kentucky. It spread across the United States and Canada, through Mexico, to the great beef-raising countries of South America. Today Herefords dominate from Australasia to the Russian steppes, including Israel, Japan, continental Europe and Scandinavia, temperate parts of Australia, Canada, the United States, Kazakhstan and Russia, the centre and east of Argentina, Uruguay, Chile, and New Zealand, where they make up the largest proportion of registered cattle. They are found all over Brazil and in some Southern African countries, notably South Africa, Zambia and Zimbabwe. Their original popularity among ranchers of the American Southwest testified to the hardiness of a breed originat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shorthorn
The Shorthorn breed of cattle originated in the North East of England in the late eighteenth century. The breed was developed as dual-purpose, suitable for both dairy and beef production; however, certain blood lines within the breed always emphasised one quality or the other. Over time, these different lines diverged, and by the second half of the twentieth century, two separate breeds had developed – the Beef Shorthorn, and the Milking Shorthorn. All Shorthorn cattle are coloured red, white, or roan, although roan cattle are preferred by some, and completely white animals are not common. However, one type of Shorthorn has been bred to be consistently white – the Whitebred Shorthorn, which was developed to cross with black Galloway cattle to produce a popular blue roan crossbreed, the Blue Grey. History The breed developed from Teeswater and Durham cattle found originally in the North East of England. In the late eighteenth century, the Colling brothers, Charles and R ...

Brahman (cattle)
The Brahman is an American breed of zebuine-taurine hybrid beef cattle. It was bred in the United States from 1885 from cattle originating in India, imported at various times from the United Kingdom, from India and from Brazil. These were mainly Gir, Guzerá and Nelore stock, with some Indu-Brasil, Krishna Valley and Ongole. The Brahman has a high tolerance of heat, sunlight and humidity, and good resistance to parasites. It has been exported to many countries, particularly in the tropics; in Australia it is the most numerous breed of cattle. It has been used in the creation of numerous taurine-indicine hybrids, some of which – such as the Brangus and Brahmousin – are established as separate breeds. History Zebuine (Asian humped) cattle were present in the United States from 1849, when a single bull of Indian origin was imported from the United Kingdom to South Carolina. In 1885 a pair of grey bulls was brought directly from India to Texas; one was large, weighing over , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heterosis
Heterosis, hybrid vigor, or outbreeding enhancement is the improved or increased function of any biological quality in a hybrid offspring. An offspring is heterotic if its traits are enhanced as a result of mixing the genetic contributions of its parents. These effects can be due to Mendelian or non-Mendelian inheritance. Definitions In proposing the term heterosis to replace the older term heterozygosis, 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 considerations such as the role of genetic variation or the effects of genetic drift in small populations on these concepts. Inbreeding depression occurs when related parents have children with traits that negatively influence their fitness largely due to homozygosity. In such instances, outcrossing shoul ...
