In recent years, the rapid development of the duck industry, in China's breeding is scattered farmers and large-scale duck farm, farm duck coexist, duck disease is becoming more and more complex, which poses a great threat to the production of ducks. Many farmers do not pay attention to the control of disinfection and environmental sanitation, which makes the breeding environment worse and worse, and the breeding efficiency is greatly reduced. Scientific and reasonable disinfection management can effectively kill and reduce the reproduction and spread of pathogenic microorganisms, control their transmission media, and cut off the transmission routes, so as to avoid common infectious diseases such as duck gizzards, salmonella, duck flu, and pasteurella ducks. The occurrence of the disease provides a safe breeding environment for the duck population and provides a good start for the work of the year.
In early spring, the temperature is relatively low, although the frequency of bacterial activity is not high, but in the case of appropriate conditions can be a large number of breeding, endangering the health of ducks. In addition, due to the cold weather in early spring, the resistance of duck body is generally weak. If neglecting the disinfection work can easily lead to the outbreak and epidemic of the disease, disinfection work is the primary task of early spring duck safety management.
Disinfection method
1. Disinfection room (with UV lamp) and disinfection tank (disinfection liquid) in front of the duck farm to disinfect the vehicles and personnel entering the duck farm.
2. Waste treatment. The duck dung, weeds, wastes, and other animal carcasses shall be removed within 6 meters of the duck house, and transported away from the duck house to be burned and buried.
3. Disinfection of empty duck houses. After the ducks are sold or transferred out, duck dung and litter shall be promptly cleaned. The duck houses shall be thoroughly cleaned and washed, and utensils such as sinks and troughs shall also be cleaned, and the walls shall be disinfected with lime water. Then use an ordinary disinfectant such as Poison-killing spray to disinfect once. One week before entering the duck, the duck house should be fumigated with formalin plus potassium permanganate for 24 hours, and then open the doors and windows for ventilation. Within 2 meters of the duck house, weeding and earthing were performed and a layer of quicklime was laid.
4. Appliances, equipment, cleaning and disinfection. The troughs, drinking fountains, brooding and warming equipment, cleaning equipment, disinfection equipment, nest boxes, etc. in duck houses must be thoroughly disinfected before use. The method is to first soak and rinse with clean water, and then use 0.1% benzalkonium bromide or other disinfectant liquids for scrubbing disinfection, rinse with water and dry. Then fumigate once again in the duck house.
5. Disinfection of the duck house in use. The weather in early spring is still cold, and most of the duck-raising households focus on thermal insulation, neglecting ventilation and ventilation. If we only emphasize the insulation of the duck house and neglect the ventilation, it can easily lead to air pollution in the house and a large number of pathogens. Ducks grow in the breeding environment of pathogens. Inhaling harmful gases such as carbon dioxide and ammonia for a long period of time are often prone to diseases such as E. coli, chronic respiratory diseases, infectious bronchitis, laryngitis, and carbon dioxide poisoning, leading to a decrease in survival rate. Therefore, in early spring, the duck farm should pay attention to heat preservation and gradually increase the ventilation and cleanliness of the house. The correct method should be ventilated 10-5 minutes every 2-3 hours. It is best to open a few skylights at the top of the shed to achieve both warmth and turbidity. People enter the duck house without bad odor sensation, and the water droplets on the plastic film around the shed are the ideal environment. The manure and litter in duck houses should also be removed in a timely manner so that the ammonia gas evacuated from duck manure can be reduced to the lowest level. The duck house can be sterilized with 0.3% peracetic acid solution. The method is to use 30 milliliters of peracetic acid solution per cubic meter of space. When spraying the duck body, avoid the opening, once a week.
6. For the duck itself, it is generally used in the winter and spring to disinfect the drinking water, that is, to add disinfectant (such as 100 toxin, strong disinfecting spirit, sodium hypochlorite, Weidao disinfectant, etc.) in drinking water according to the ratio. Once in the week, ducklings are usually treated with 1 potassium permanganate (warm water).
7. Staff disinfection. Before the duck farm staff enters the production area, they must replace the disinfected work clothes, rubber shoes, etc., and sterilize them under ultraviolet light for about 10 minutes before entering the duck farm. Any qualified duck farm can ask the staff to change all the clothes and take a bath. Work clothes, etc. must be disinfected daily with ultraviolet light and washed once a week.
Rational selection of drugs
According to the identification of disinfecting drugs, combined with their own environment, the purpose of disinfection, the object, epidemiological trends, and disease conditions of ducks, according to the principle of high efficiency, broad spectrum, economy, and small side effects, disinfectant drugs should be selected, and strict attention should be paid to disinfectant drugs. Instructions for use Dispense disinfectants, improve the effectiveness of disinfectants, and achieve the purpose of disinfection.
1. The choice of disinfectant for drinking water. Drinking Water Disinfection Requirements The disinfectant used is not corrosive and irritating to the intestines of ducks. The commonly used drugs are halogens. Sodium hypochlorite, bleaching powder, dichloroisocyanuric acid, and chlorine dioxide are commonly used. Low concentrations of ducklings are used. Potassium permanganate drinking water can also clear the small intestine.
Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods. They can be used in the pharmaceutical industry, food industry, health industry, beauty industry and other industries.
Plant extracts are based on plants as raw materials. According to the needs of the use of the final product extracted, through physical and chemical extraction and separation processes, one or more effective ingredients in the plant are obtained and concentrated without changing the effective ingredients. The product formed by the structure. According to the different components of the extracted plants, glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc. Are formed; according to different properties, they can be divided into vegetable oils, extracts, powders,crystalline powder, etc.
