What Is a Broiler What is a broiler Continue This article is about the bird. For other purposes, see Broiler. BroilerDistributionWorld-wideUseMeatTraitsSkin colorYellowClassificationPoultry A broiler is any chicken (Gallus gallus domesticus) that is bred and grown specifically for the production of meat. Most commercial broilers reach slaughter weights between the ages of four and seven weeks, although slower growing breeds reach slaughter weights of about 14 weeks. Typical broilers have white feathers and yellowish skin. A broiler or sometimes broiler friser is also used sometimes to refer specifically to young chickens under 4.5 pounds, compared to large roasters. Due to extensive breeding for rapid early growth and livestock use to sustain this, broilers are susceptible to several welfare problems, especially skeletal malformations and dysfunction, skin and eye lesions and congestive heart disease. In order to ensure good well-being, the herd needs to be regularly assessed for ventilation, shelter, stocking density and home procedures. Tribal stock (broiler-selectors) grow to maturity, but also have their own welfare problems associated with the frustration of high-motivation feeding and pruning the beak. Broilers are usually grown as mixed sex flocks in large sheds in intense conditions. Modern Breeding Play Media Video chickens are almost ready to be killed in a modern broiler farm before the development of modern commercial meat breeds, broilers were mostly young male chickens taken from farm herds. Pedigree breeding began around 1916. At that time there were magazines for poultry farming. The crossbreeded chicken variety was made from a male naturally bi-breasted Cornish strain and a female of a high, large-gauge strain of white Plymouth rocks. This first attempt at meat interbreeding was made in the 1930s and became dominant in the 1960s. Initially, interbreeding suffered from problems of low fertility, slow growth and susceptibility to disease. Modern broilers have become very different from Cornish/Rock crossing. For example, Donald Shaver (originally an egg-production breeder) began collecting breeding stock for a broiler program in 1950. In addition, breeds usually favored, Cornish Games, Plymouth Rock, New Hampshire, Langshans, Jersey Black Giant and Brahma were included. Cobb acquired a white feathered women's line. A full-scale breeding programme was launched in 1958, with commercial deliveries to Canada and the United States in 1959 and Europe in 1963. As a second example, colored sex broilers were proposed by Shaver in 1973. Genetics was based on the company's egg breeding plan, which was developed in the mid-1960s. The difficulty facing the breeders of the colored broiler lies in the that chicken should be white-haired by the slaughter age. Age. 12 years, the exact color of sexing without sacrificing economic traits has been achieved. Artificial insemination Artificial insemination is the mechanism by which sperm are deposited in the reproductive tract of the female. Artificial insemination provides a number of benefits associated with reproduction in poultry production. Broiler breeds have been chosen specifically for growth, forcing them to develop large pectoral muscles that interfere and reduce natural mating. The amount of sperm produced and deposited in the chicken's reproductive tract may be limited because of this. In addition, men's overall sex drive can be significantly reduced due to growth choices. Artificial insemination has allowed many farmers to incorporate individual genes into their stock, increasing their genetic quality. Abdominal massage is the most common method used to collect sperm. During this process, the rooster is restrained, and the rear area, located to the tail and behind the wings, caressed. It's done gently but quickly. Within a short period of time, the male should get an erection of the phallus. As soon as this happens, the cloaca is compressed and the sperm is collected from the outer dryer of the vessel deferens. During in vitro fertilization, sperm is most often deposited intravaginally with a plastic syringe. In order for the sperm to be deposited here, the vaginal opening is everted through the cloaca. This is simply done by applying pressure on the chicken's stomach. The sperm- containing tool is placed 2-4 cm into the vaginal opening. As sperm is currently deposited, the pressure exerted on the chicken's stomach is being released simultaneously. The person performing this procedure usually uses one hand to move and guide the tail feathers, using the other hand to insert the tool and sperm into the vagina. General Biology Modern commercial broilers, such as Cornish Crosses and Cornish Rocks (citation necessary), are artificially selected and bred for large-scale, efficient meat production. They are marked by very rapid growth, high feed conversion rates and low activity. Modern commercial broilers are bred to reach a slaughter weight of about 2 kg in just 5-7 weeks. As a result, the behavior and physiology of broilers prepared for meat are the behavior of immature birds, not adults. Slow-growing free and organic strains have been developed that reach a killer weight between the ages of 12 and 16 weeks. Typical broilers have white feathers and yellowish skin. A recent genetic analysis showed that the yellow skin gene was incorporated into poultry by hybridizing with the grey jungle bird (G. sonneratii). Modern crosses are also good for meat production because they lack the typical hair that breed breeds which should be removed by sowing after plucking the carcass. Both men and women broilers grew for meat. Broiler behavior behavior changes in the environment, and changes as broiler age and body weight rapidly increase. For example, the activity of broilers growing outdoors is initially greater than broilers preparing indoors, but from six weeks reduced to comparable levels in all groups. The same study shows that in an outdoor group, surprisingly little benefit is made from extra space and objects such as perches - it was suggested that the main cause of this was foot weakness, as 80 percent of birds were found to have gait abnormalities at seven weeks of age. There is no evidence of a decrease in motivation to expand the behavioural repertoire, as, for example, in outdoor groups, for example, outdoor groups still retained soil, as such behaviour could also be performed from a reclining posture rather than standing. The study of the frequency of all sexual behavior shows a significant decrease with age, which indicates a decrease in libido. Reducing libido is not enough to explain the decline in fertility in heavy cocks at 58 weeks and is probably the result of a large volume or conformation of men at this age of intervention in some way with sperm transmission during copulation, which otherwise look normal. Feeding and converting feed chickens are omnivorous and modern broilers get access to a special diet of high-protein feed, usually delivered through an automated feeding system. This is combined with artificial lighting conditions to stimulate nutrition and growth and therefore desired body weight. In the United States, the average feed conversion rate (FCR) of broilers was 1.91 pounds of feed per pound of live weight in 2011, up from 4.70 in 1925. Canada has a typical FCR of 1.72. New zealand commercial broiler farms recorded the world's best chicken broiler FCR, stable at 1.38 or below. Welfare gives meat birds one-day chicks arriving to unpack and place in the barn. Young birds tucked into a closed broiler house. Artificial selection has led to a significant increase in the speed at which broilers develop and reach a killer weight. The time required to reach 1.5 kg of live weight was reduced from 120 days to 30 days between 1925 and 2005. Selection for rapid early growth and feeding and management procedures to support such growth have led to various social security problems in modern broiler strains. The well-being of broilers is of particular concern, given the large number of people that are produced; for example, in the United States, about 9 broiler chickens. Cardiovascular dysfunction Choice and husband for very rapid growth means that there is a genetically induced discrepancy between the energy-saving organs of broilers and his Bodies. Rapid growth can lead to metabolic disorders such as sudden death syndrome (SDS) and ascites. SDS is an acute heart failure disorder that affects mostly men of fast-growing broilers who appear to be in good condition. Affected birds suddenly start to flap their wings, lose their balance, sometimes scream, and then fall on their backs or sides and die, usually all within a minute. In 1993, broiler manufacturers in the UK reported a 0.8% incidence. In 2000, the mortality rate of VDD in Europe ranged from 0.1% to 3%. Ascites is characterized by hypertrophy and cardiac dilation, changes in liver function, pulmonary insufficiency, hypoxemia and accumulation of large amounts of fluid in the abdominal cavity. Ascites develops gradually and birds suffer for a long period before they die. In the UK, up to 19 million broilers die in their sheds from heart failure each year. Skeletal breeding dysfunction for breast muscle enlargement means that the center of gravity of broilers has moved forward and their breasts are wider than their ancestors, which affects the way they walk and puts extra strain on the hips and legs. There is a high frequency of skeletal problems in broilers, mainly in the locomotive system, including deformations of varus and valgus, osteodystrophy, dychondroplasia and femoral head necrosis. These leg abnormalities impair the locomotive abilities of birds, and lame birds spend more time lying down and sleeping. The behavioral activity of broilers decreases rapidly from 14 days. Reduced movement also reduces bone overcomotion and leads to skeletal abnormalities; they are reduced when broilers are carried out under experimental conditions.

  • Broiler Chickens
    The Life of: Broiler Chickens Chickens reared for meat are called broilers or broiler chickens. They originate from the jungle fowl of the Indian Subcontinent. The broiler industry has grown due to consumer demand for affordable poultry meat. Breeding for production traits and improved nutrition have been used to increase the weight of the breast muscle. Commercial broiler chickens are bred to be very fast growing in order to gain weight quickly. In their natural environment, chickens spend much of their time foraging for food. This means that they are highly motivated to perform species specific behaviours that are typical for chickens (natural behaviours), such as foraging, pecking, scratching and feather maintenance behaviours like preening and dust-bathing. Trees are used for perching at night to avoid predators. The life of chickens destined for meat production consists of two distinct phases. They are born in a hatchery and moved to a grow-out farm at 1 day-old. They remain here until they are heavy enough to be slaughtered. This document gives an overview of a typical broiler chicken’s life. The Hatchery The parent birds (breeder birds - see section at the end) used to produce meat chickens have their eggs removed and placed in an incubator. In the incubator, the eggs are kept under optimum atmosphere conditions and highly regulated temperatures. At 21 days, the chicks are ready to hatch, using their egg tooth to break out of their shell (in a natural situation, the mother would help with this). Chicks are precocial, meaning that immediately after hatching they are relatively mature and can walk around.

REV. 29 (1978) www.NationalAgLawCenter.org UNITED STATES V. NATIONAL BROILER MARKETING ASSOCIATION: WILL THE CHICKEN LICKIN' STAND? CHARLES GORDON BROWNt Most of the nation's major broiler! producers are skeptical of the wisdom of the old adage "build a better mouse trap and the world will beat a path to your door." The broiler industry built a better mouse trap all right. Sweeping technological and organizational innovations have transformed the industry into one of major agricultural importance. From a meager $19 million in 1934,2 gross farm income from broilers soared to $2.9 billion in 1975,3 a more than fifteen hundred percent increase in just four decades. The remarkable growth of the industry has been accompanied by an even more remarkable phenomenon: broilers are cheaper today than ever before, despite escalating production costs,4 because the efficiency of the industry has kept prices low. 5 The broiler industry's mouse trap has been so success­ ful, in fact, that it has become a model for other areas of agricultural production.6 But the news is not all good.

By Verel W. Benson and Thomas J. Witzig, Conunodity Economics Division, Economic Research Service, U.S. Department of Agriculture, Agricultural Economic Report No. 381. This report updates "The Chicken Broiler Industry: Structure, Practices, and Costs," Marketing Research Report No. 930, published in May 1971. ABSTRACT Extensive changes in production, processing, and marketing during the last few decades have changed the chicken broiler industry from one of small, widely scattered farms to one that is large, concentrated, and efficient. More than 99 percent of all broilers produced are grown under contract and by integrated firms which vary in size of operation and complexity. About 84 percent of all production is concentrated in 10 States. Some of the other factors that contributed to these changes are costs, energy use, prices, processing, marketing, and demand. Keywords: Broilers, consumption, costs, demand, energy, marketing, processing. ACKNOWLEDGMENTS The authors wish to acknowledge the assistance of George B. Rogers, William L. Henson, Harold B.
