Description

Disinfection equipment for poultry hatching device and its disinfection method

technical field

The invention relates to the technical field of poultry hatching environment regulation and control, in particular to disinfection equipment for poultry hatching devices and a disinfection method thereof.

Background technique

my country is a big country in poultry breeding and consumption. The production and consumption of poultry meat and poultry eggs ranks among the top in the world. Unlike mammals, the embryonic development of poultry is independent of the mother, which is convenient for hatch management and operation. With the development of the poultry breeding industry, the hatching of existing poultry eggs has all been artificially hatched. According to the poultry industry report, in 2021, the hatching amount of eggs of laying hens, broilers and meat ducks in my country will be close to 19 billion. For other poultry such as pigeons, quails, etc., the hatching amount of breeding eggs is close to 20 billion pieces per year. Therefore, the poultry hatching market is huge, and the hatching industry occupies an important position in the animal husbandry.

Artificial hatching is a key link in modern poultry production. The hatchability and hatching quality are the lifeline of the hatching market, and are also related to the economic benefits of the entire poultry breeding industry. Under the condition of a certain variety and egg quality, environmental regulation is the key factor affecting the hatching quality. The key factor. Egg disinfection is a key measure to control the spread of diseases. It can reduce the spread of vertical infectious diseases and other common diseases. Now the egg hatching market attaches great importance to the disinfection of the eggs before hatching. After the eggs are laid, they will be more or less polluted, and many bacteria will be attached to the eggshells. As time goes by, the number of bacteria will increase rapidly. In order to prevent bacteria from entering the shell through the eggshell membrane and contaminating the eggs, in the poultry farm, the collected eggs are disinfected in the poultry house disinfection room within 2 hours. At the same time, strict disinfection management will also be carried out in the hatchery egg warehouse control.

Commonly used disinfectants in hatcheries include chemical disinfectants such as phenols, aldehydes, quaternary ammonium salts, iodine, and chlorine, but they will cause some pesticide residues, and the disinfection effect is usually between 90-95%. There will be some germs surviving, and the remaining germs will continue to reproduce during the egg hatching process due to suitable temperature and humidity conditions. When the amount of germs reaches a certain level, it will endanger the production and development of the embryo, and even cause death. Still have higher death rate in the embryo in the hatching of existing kind of egg, especially the higher death rate in the kind of egg hatching embryo of duck, goose and pigeon, wherein main reason is exactly germ infection. And in the hatching of existing kind of egg, also have to adopt the ultraviolet ray sterilization mode, but this kind mode generally is to carry out disinfection before hatching, can not satisfy the requirement to the whole process disinfection of hatching.
