Australian Brangus
Australian Brangus are a polled breed of beef cattle, developed in the tropical coastal areas of Queensland, Australia by crossbreeding Brahman and Angus cattle during the 1950s. History Brangus were first developed in the United States and later developed independently in Australia as the Australian Brangus. The breed was produced to establish higher tick and heat tolerance Plant breeding is process of development of new cultivars. Plant breeding involves development of varieties for different environmental conditions – some of them are not favorable. Among them, heat stress is one of such factor that reduces the pr ... than that of other cattle breeds. They are a widely used source of meat throughout Australia and exported to countries such as Japan and America. Benefits The Australian Brangus cattle are about Brahman and Angus in their genetic makeup, however, the Brahman content can range from 25% to 75%. This allows beef producers to select cattle suitable for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polled Livestock
Polled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC. Terminology The archaic term or is sometimes used to refer to hornless livestock (especially cattle) in folk songs, folk tales, and poetry, and in the name of the polled Irish Moiled cattle breed. "Muley" derives from Irish and Scottish Gaelic ''maol'', and Welsh ''moel''. Genetics In cattle, the polled allele is genetically dominant to that for horns. The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being developed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Angus (cattle)
The Aberdeen Angus, sometimes simply Angus, is a Scottish breed of small beef cattle. It derives from cattle native to the counties of Aberdeen, Banff, Kincardine and Angus in north-eastern Scotland. In 2018 the breed accounted for over 17% of the UK beef industry. The Angus is naturally polled and solid black or red, although the udder may be white. The cattle have been exported to many countries of the world; there are large populations in Australia, Canada, New Zealand, South America and the United States, where it has developed into two separate and distinct breeds, the American Angus and Red Angus. In some countries it has been bred to be taller than the native Scottish stock. Its conservation status worldwide is "not at risk"; in the United Kingdom the original Native Aberdeen Angus – cattle not influenced by cross-breeding with imported stock – is listed by the Rare Breeds Survival Trust as "at risk".

Brangus
The Brangus is an American hybrid breed of beef cattle derived from cross-breeding of American Angus and Brahman stock. Registered animals have 5/8 Angus and 3/8 Brahman parentage. A similar hybrid breed, the Australian Brangus, was separately developed in Australia from about 1950. History Research into crossbreeding of Angus and Brahman stock was begun in about 1932 at the Iberia Livestock Experiment Station of the Agricultural Research Service of the United States Department of Agriculture near Jeanerette, Louisiana, where crossbreeding of Brahman and Shorthorn cattle had already shown good results. It was hoped that the good adaptation of the Brahman to hot and humid conditions could be combined with the better meat qualities of the Angus, as well as its black coat and polled characteristic. An ideal proportion of 5/8 Angus to 3/8 Brahman was established. By 1949 the cattle were distributed in sixteen American states and in Canada. A breed society Breed clubs are associat ...

Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In addit ...

Thermoregulation
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above for six hours. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It results when the homeostatic c ...
