introduction history of industry POULTRY-KEEPING is interesting because it gives pleasure as well as profit to persons of both sexes, all ages all walks in life m all sections of the country It is useful alike on the farm and in the City back-yard In the cold in the sunny, in the hill and mountain country, or on the plain It may be conducted as an exclusive business or as a side line It affords pleasure and profit for rich and poor It is the universal agricultural industry   he best way to start a poultry enterprise is to begin modestly and let the business build its increases  It is believed that poultry production started in Asia over 3000 years ago. Although some records suggest that chickens were raised around 3200 BC, archaeological evidence only goes back to about 2000 BC. It is considered that chickens originate from India, and that the red jungle fowl is an ancestor to today’s modern chicken. The breeding of chickens in captivity dates back to at least 1400 BC in Egypt. But intensive poultry production only  before 7500 BCE. Chickens were brought to Sumer In Thebes, Egypt, the tomb of Haremhab, built about 1420 BCE, shows a depiction of a man carrying bowls of ostrich eggs and other large eggs,  arrived in Greece around 800 BCE, where the quail had been the primary source of eggs IN ancient Rome, eggs were preserved using a number of methods, and meals often started with an egg course The dried egg industry developed in the 19th century, before the rise of the frozen egg industry. In 1878, a company in St. Louis, Missouri started to transform egg yolk and white into a light-brown, meal-like substance by using a drying process.   intensive poultry production only began in the 20th century. Indeed, the past 100 years have seen an impressive growth, chiefly in the production of chickens and eggs, turkeys, ducks, and geese. It is the advent of vaccination for conditions such as Marek’s disease, in addition to preproducing good quality day-old chicks starts with the breeder flock. Not only is the quality of the egg important, but also the health and nutritional status of the breeders are having an impact on day-old markable improvements in nutrition, genetics, and management, that has allowed the poultry industry to quickly develop since the late 1960s    In general we can divide the factors associated with chick quality in two categories: EGG RELATED FACTORS hatchery and brooding management factors (egg handling , incubation, chick processing and placement SOURCES OF CHICKENS Primary breeding companies supply the breed performance These white hybrid layers are capable of laying 324 eggs per hen housed at 72 weeks of age with a feed conversion of 3.04 pounds of feed per dozen or 1.91 kg feed per kg of egg.der stock chickens for various breeder/hatchery companies who then supply the day-old pullet chicks to be grown into laying hens housing system feeding program in general   lighting program  economy of layer farm indices layer health management vaccination program suggested vaccination program spray vaccine onovo vaccine hatchary vaccine fowl pox vaccine cleaning disinfection receiving baby chicks  automation in layer farm egg collection manure removal flock following rearing table postmortem  procedures serology how to take blood sample how to make Elisa test  Elisa software
