Disinfection with chickens is a measure for the production of green products

Disinfection with chickens is an effective measure to prevent and control avian influenza and Newcastle disease in large-scale @#@ 230 @#@ farms, especially when there is more spring wind, it is especially necessary to raise chicken houses of different ages. Specific operation methods:

Choose the appropriate time in winter when the temperature is low, it is best to choose the noon when the temperature is high, the aerosol evaporates quickly, the chicken breathes quickly, absorbs quickly, and acts quickly. In spring and summer, the normal temperature is higher than 20 ° C. It is best to choose the afternoon or evening. The temperature is constant. The aerosol evaporates slowly, and the floating disinfection time in the house is long and the effect is good.

Choosing the right medicine to disinfect chickens has a narrow application area, which is mainly determined by the corrosion of the respiratory tract and digestive tract mucosa of chickens and the lethality of pathogenic microorganisms in the house. Strong acids are highly lethal, but they are corrosive to chicken cages in chicken houses and corrosive to human and chicken mucosa. Choose neutral drugs with high efficiency, broad spectrum, strong, non-toxic irritation, no peculiar smell, no residue on eggs and skin, quaternary amine diquaternary amine salts with no corrosion on mucous membranes are ideal, commonly used commodities include Baiduqing, Baiduqing, 1210, Jundu No.5, holy disinfectant, strong gold iodine, etc., do not simply look at the variety of commodity names, but look at the main chemical components, chemical composition and structure to choose.

The dilution ratio of disinfection drugs is determined by the chemical molecular structure of the drugs combined with the structure of water molecules. The lethality of different proportions is different. The structural formula of drug molecular groups is different, and the ability to compete for pathogens is different. Generally, it is divided into three grades: emergency disinfection is aimed at serious pollution in epidemic season. The dilution ratio is larger and the water is less. Prevention disinfection in epidemic period is diluted by 1:1000~2000 times. Usually disinfection is generally 2000~3000 dilution times, especially targeted disinfection, according to the characteristics of pathogens to determine the dilution times. Bacteria dilution times are large, add more water, often 2000 times to 3000 times, virus dilution times are small, add less water, generally 500 times to 1000 times, according to the need for necessary dilution.

Choose moderate water quality water quality is different, there are two criteria, one is PH value, the other is hard water and soft water, hard water contains calcium and magnesium ions, competition and drug molecular groups combined, affecting the combination of pathogens, but also affect lethality, so in the dilution of quaternary amine drugs to choose soft water, or boiled water. PH value is 6~7 neutral water is good, but also does not destroy the chemical structure of diquaternary amine.

Physical environment Physical environment refers to the storage of items in the house, sticks, broken glass, egg skin, chicken feathers, chicken manure and other miscellaneous garbage, to be completely removed.

Close the door for about 1 hour after spraying the drug. The drug should float in the air for as long as possible, at least half an hour. Moreover, the condition of the chickens should be constantly observed to prevent accidents such as poisoning, suffocation and disturbance.

In short, spray disinfection is a technology that must be mastered in the process of raising chickens. Although there is no index visible to the naked eye, there is a standard for healthy growth and infection of chickens. High disinfection technology, good chicken growth, high productivity, less elimination, less dosage, less infection, less drug residue, is the basic technology of disease prevention, the first important checkpoint of disease prevention.
