Broiler
A broiler is any chicken (''Gallus gallus domesticus'') that is bred and raised specifically for meat production. Most commercial broilers reach slaughter weight between four and six weeks of age, although slower growing breeds reach slaughter weight at approximately 14 weeks of age. Typical broilers have white feathers and yellowish skin. Broiler or sometimes broiler-fryer is also used sometimes to refer specifically to younger chickens under , as compared with the larger roasters. Due to extensive breeding selection for rapid early growth and the husbandry used to sustain this, broilers are susceptible to several welfare concerns, particularly skeletal malformation and dysfunction, skin and eye lesions and congestive heart conditions. Management of ventilation, housing, stocking density and in-house procedures must be evaluated regularly to support good welfare of the flock. The breeding stock (broiler-breeders) do grow to maturity but also have their own welfare concerns re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature. Genetic studies have pointed to mult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feed Conversion Ratio
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows,Dan Shike, University of IllinoiBeef Cattle Feed Efficiency/ref> pigs, chickens, and fish) the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output (thus mass of feed per mass of milk or meat). In some sectors, feed efficiency, which is the output divided by the input (i.e. the inverse of FCR), is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI). Background Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outp ...

Poultry
Poultry () are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails, and turkeys). The term also includes birds that are killed for their meat, such as the young of pigeons (known as squabs) but does not include similar wild birds hunted for sport or food and known as game. The word "poultry" comes from the French/Norman word ''poule'', itself derived from the Latin word ''pullus'', which means "small animal". Recent genomic study involving the four extant Junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia - although this was previously believed to have occurred later - around 5,400 years ago - in Southeast Asia. The process may have originally occurred as a result of people hatching and rearing young birds fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth Rock Chicken
The Plymouth Rock is an American breed of domestic chicken. It was first seen in Massachusetts in the nineteenth century, and for much of the early twentieth century was the most widely kept chicken breed in the United States. It is a dual-purpose chicken, raised both for its meat and for its brown eggs. It is resistant to cold, easy to manage, and a good sitter. History The Plymouth Rock was first shown in Boston in 1849, but was then not seen for another twenty years. In 1869, in Worcester, Massachusetts, one D.A. Upham cross-bred some Black Java hens with a cock with barred plumage and a single comb; he selectively bred for barred plumage and clean (featherless) legs. His birds were shown in Worcester in 1869; the modern Plymouth Rock is thought to derive from them. Other people have been associated with the development of the Plymouth Rock, as have other chicken breeds including the Brahma, the Cochin (both white and buff), the Dominique, and the White-faced Black Spa ...

Dyschondroplasia
Tibial dyschondroplasia (TD) is a metabolic disease of young poultry that affects the growth of bone and cartilage. Often occurs in broilers (chickens raised for meat) and other poultry which have been bred for fast growth rates. The tibial cartilage does not mature enough to ossify (turn into bone). This leaves the growth plate prone to fracture, infection, and deformed bone development. It is the leading cause of lameness, mortality, and carcass condemnations in commercial poultry.

Cornish Chicken
The Indian Game is a British breed of game chicken, now reared either for meat or show. It originated in the early nineteenth century in the counties of Cornwall and Devon in south-west England. It is a heavy, muscular bird with an unusually broad breast; the eggs are brown. In the United States the name was changed in the early twentieth century to Cornish. A white variant, the White Cornish, was developed there at about the same time, and is much used in modern industrial chicken meat production in many parts of the world, either for cross-breeding to produce hybrid broilers, or to produce fast-growing " game hens". History The breed was developed by Sir Walter Gilbert, of Bodmin in Cornwall, in about 1820. It was intended to be a gamecock, but had no aptitude for cockfighting. It is recognised as "Indian Game" in Australia, by the Poultry Club of Great Britain in the United Kingdom, and by the Entente Européenne in Europe. In the United States the name was changed i ...

Donald Shaver
Donald McQueen Shaver (born August 12, 1920) was a Canadian pioneer in the poultry industry, who founded a breeding company that achieved worldwide prominence. At its peak Shaver Poultry Breeding Farms was the world's largest, being one of only two "world class foundation breeding" companies in Canada. Shaver died in 2018 of age related causes. Early life Born in Galt Ontario (today part of Cambridge) he attended Galt Primary School and the Galt Collegiate Institute, graduating 1937. His mother's family was of Scottish descent, while his father's side was Hessian, settling in Canada around 1840. The family name was originally "schæfære" meaning shepherd. He developed an interest in poultry when in 1932 he was given two hens by a great aunt. Young Don would travel by bicycle to attend poultry conferences given by Prof. W.R. Graham at OAC. His business was first named Grand Valley Hatchery after the local region in Ontario. By the mid '30s he was selling 2000 chickens a week ...

Ascites
Ascites is the abnormal build-up of fluid in the abdomen. Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. Symptoms may include increased abdominal size, increased weight, abdominal discomfort, and shortness of breath. Complications can include spontaneous bacterial peritonitis. In the developed world, the most common cause is liver cirrhosis. Other causes include cancer, heart failure, tuberculosis, pancreatitis, and blockage of the hepatic vein. In cirrhosis, the underlying mechanism involves high blood pressure in the portal system and dysfunction of blood vessels. Diagnosis is typically based on an examination together with ultrasound or a CT scan. Testing the fluid can help in determining the underlying cause. Treatment often involves a low-salt diet, medication such as diuretics, and draining the fluid. A transjugular intrahepatic portosystemic shunt (TIPS) may be placed but is associated with co ...
