Brief introduction to nouns:

Poultry refers to birds and animals raised artificially, mainly for their meat, eggs and feathers, but also for other purposes. Generally speaking, they are pheasants and ducks, such as chickens, geese and quails, but there are also birds of other families, such as turkeys, pigeons and various songbirds. For example, among domestic ducks domesticated by wild ducks, Beijing Duck is a good variety, with an annual output of 70 ~ 120 eggs. The Beijing Roast Duck made from it is well-known at home and abroad for its delicacy.

Origin:

All kinds of domestic chickens in the world originated from red grouse, which are distributed in southern provinces of China, Indian and Southeast Asia. It was first domesticated in China and India, with a history of more than 5,000 years in China, and then gradually spread to Europe, the United States, Africa and all over the world. Turkey is a wild bird native to America. Later, it was domesticated and became poultry. Its ancestors also lived a wild life in the south-central United States.

Reproduction and incubation:

Poultry breeding and hatching are generally divided into artificial hatching and female hatching, but with the development of science and technology in recent years, artificial hatching technology has matured and occupied most of the market. Generally, there should be special incubation equipment, that is, the so-called chick incubator, which is similar to a box with heating function, and there should be a special incubation room with a relatively good environment.

After each batch is hatched, the equipment, appliances and rooms should be cleaned and disinfected immediately. Cleaning and disinfection steps of incubator and incubator: take out incubator tray and humidified water tray, rinse with water first, then scrub the inner and outer surfaces of incubator with bromogeramine (pay attention to the cleanliness of the top of incubator), rinse the floor of incubator with high-pressure water, and then fumigate and disinfect incubator, with 42ml formalin and 2 1g potassium permanganate per cubic meter.

Nutritional value:

The meat and eggs of poultry are rich in nutrition. Poultry meat is rich in protein, phosphorus and other minerals, and a lot of vitamin B complex. Compared with most beef and pork, the meat fat of poultry is lower, and the liver of poultry is rich in vitamin A. For small farms and families, poultry is a relatively more convenient living thing because of its small size.
