Large Scale Raising
16th century, cockfighting flourish in England, King Henry VIII keen cockfight held at Whitehall Palace, makes this game became popular in the UK national sport. In 1849, Queen Victoria issued a royal decree to ban cockfighting activities. Since then, chicken feeding became a popular hobby for British. 1849, Birmingham exhibition held in the central of England, where China's cochin stole the show for its huge size, filled with fluffy feather over the whole body, quickly caused a sensation in England and let people have crazy enthusiasm for poultry
Late 19th century, the poultry boom crossed the Atlantic Ocean, sweeping the U.S. East Coast that chicken raising increasingly became American's hobby. In 1873, the American Poultry Association set standards to develop farmers selectively breeding purebred chickens. In 1880, US census counted the number of chicken for the first time that the whole of USA had 102 million at that time, and rapidly increased to 258 million. In 1891, poultry breeding started a a hundred-year history from family farming to large-scale industrial faming, when Cornell University became the first one offer the course of poultry farming among of all agriculture universities.
Early 20th century, chicken still played a minor role in the American eating habits and economy. After industrial stage marked by cattle and pigs entering into the mechanized slaughterhouse, chicken were still in the free-arrange and small scale farming stage. In the middle of the 20th century , the appearance of feedstuff with antibiotics and vitamins adding brought a significant breakthrough for this industry , then a large farm with 250,000 chicken followed. In this new agriculture field, vitamin D become an important factor for chicken meat price. Scientists found that lack of vitamin D can cause metabolic disorders and rickets. Chicken, as the same with people, need get sun to synthesize vitamin D by itself to keep bones healthy. However, keeping chicken outside may face some weather and diseases and other uncertainties. Therefore, in order to increase chicken weight, people added cod liver oil to the feed, set up large shed through temperature control, feedstuff, lighting.
In 1928, during the presidential election, Republican candidate Hoover promised to the American people in campaign speech that , "if he is elected president, Americans will forever fight against poverty, each port will have a chicken in every family. President Hoover certainly did not realize his promise. The Great Depression followed to make the millions of farms forced to close. In order to ease economy crisis, in April 1933, the U.S. Congress passed Agriculture Mortgage Law to offer short-term loans to poultry farms, in order to promote farmers specialize in production of chicken meat and egg, which greatly improved the production of eggs. Some farmers began to specialize in modern egg farm, which greatly improved the egg production. Betty MacDonald's classical memoir Egg and I and its same name film adaption described this subtle economic change, which can be enough to prove that all art comes from life.
The profit of chicken faming was increased by research on genetics and automation. At present, the most advanced chicken house has the same size as two football fields, with automatic feeding and watering for every one hour. The bottom of cage inclines slightly, so that the produced eggs roll onto the conveying belt and washed, graded, packed automatically. Undoubtedly it is a huge change that consumers can purchase fresh meat with low price, which should thanks to the amazing advances in technology and the market at different times.
Nowadays, the number of chickens on the earth has far exceeded the human race, almost three times as humans. Worldwide chicken has showed us a epic saga of culture, religious and food, offered us delicious omelette, chicken casserole, braised chicken, fried chicken and chicken liver sauce and also provided us an interesting answer: based on the evolutionary history, scientists suspected that herbivorous dinosaurs generally ate horsetail and ferns, therefore meats of dinosaurs were more like poultry meat, rather than steaks or pork chops and its flavor should be closer to the birds - Eagle or chicken. Thus, when a child went to the natural Natural History Museum for the first time, and asked their parents " what is the taste of dinosaurs' meat?", and now parents can answer " Chicken Flavor".
During World War II, due to lack of beef and pork, the demand for chicken meat was increasing gradually for it as the sources of protein and then it became the main meat for human. After the war, American poultry farming industry moved from north to south. The southern national condition was good for its mild climate and convenient grain transportation, which made the chicken meat price cheaper. In efficient conversion from grain to protein, the production cost of modern chicken is much lower. For each live chicken, one pound added just only needed less than two pound feed, less than half of 1945 's, however, one pound of beef need seven pounds of feed, and for one pork, more than three pounds of feed needed.
