After entering March, the weather gradually warmed and livestock husbandry households began to make up the bar. Now we will introduce the key issues related to animal husbandry and aquaculture as follows: 1. Complete and thorough disinfection of livestock and poultry pens should fully utilize the favorable conditions for livestock and poultry sold before the Spring Festival. Before restocking, they must be strictly disinfected to kill pathogenic microorganisms. Ensure the safe production of livestock and poultry. Disinfection objects include: livestock and poultry manure, roads, sites, houses, appliances, feed grains, water basins, and transportation vehicles. 1. Disinfection of housing: excrement, litter (grass) and other cleaning materials, compaction and fermentation (preferably in a dry place far away from the site, excavation special fermentation pit seal disinfection); floors, walls, doors, windows, appliances, etc. According to the type of infectious disease, choose a suitable disinfectant for thorough spraying and cleaning. 1 Disinfectant can be used for antivirus or 111 to kill 1:300 to 1:400; disinfect the king 1:300; also use 1:300 to kill the spray. 2 Generally, at least about 1 liter of disinfectant is used per square meter. After disinfectant is sprayed, close the doors and windows for 2 to 3 hours. Then open the windows and ventilate and then wash the feeder trough with clean water. If it is a soil shed, it should be used after disinfection. Washers and lime compaction. 3 formalin fumigation: The specific approach is to put potassium permanganate in the container, placed in a sterile place, and then join the formalin. Since the two drugs react to boil and generate a large amount of bubbles, the containers used are deeper and the volumes are 10 times greater than the formaldehyde solution used. However, do not add potassium permanganate to formalin. The drug concentration was 28 ml of formaldehyde solution per square meter of space, 14 grams of potassium permanganate, and 14 ml of water. It is generally required to seal and sterilize for 12 to 24 hours, and then open the door and window to drain the remaining gas. 4 It can also be spray sterilized with 0.2% to 0.5% peracetic acid (2,000 ml/m3). 5 Disinfection of surrounding sites and roads can be sprayed with 10% bleach or 0.5% peracetic acid (200 ml/m2). If the soil site should be excavated surface bleaching powder, mixed, buried deep; cement, asphalt sites, roads can use 2% to 3% caustic soda liquid disinfection, must be washed repeatedly before use (there should be a certain interval between the time, the best Rinse every other day). 2. Disinfection of water: In the past, the use of boiling water and ultraviolet radiation to sterilize drinking water was troublesome and costly. Now available: 1 anti-drug Wei, 100 poisoning, etc. can be added according to the proportion of disinfection; can also be used for every 1000 milliliters of drinking water plus chloramine 0.5 to 1 gram, or add 25% of available chlorine bleach 2 to 4 grams. 2 Sewage can add 6-10 grams of bleaching powder per cubic meter of water (depending on the level of water pollution increase or decrease), after 6 hours can kill pathogens in the water; can also be filtered after the addition of gelatin precipitation and disinfection. 3. Disinfection of vehicle tools: 1 Carriage tools for general healthy livestock and poultry products and products shall be mechanically removed and washed with hot water at 60-70°C. (2) Vehicles and tools for transporting infectious diseases livestock and poultry (including viruses and bacterial livestock) shall be cleaned and sterilized on the next day in addition to 1% to 2% hot caustic soda solution. If the pollution is serious and the disease is severe, effective disinfection and cleaning should be repeated. 4, wear overalls and caps, regular disinfection: when there is an epidemic should pay attention to work clothes and caps cleaning and disinfection work, (if necessary, replace every day) can usually be used to sterilize sunlight, can also be sterilized by boiling or formalin fumigation 20 minutes. Whether it is usual or epidemic, uniforms are not allowed to pass out of the production area. Unconditional should also refer to the above disinfection requirements, frequently changing, washing, pants, and disinfection. 5. Disinfect workers: Disinfect soap and wash hands several times to disinfect; after the epidemic should be washed with soap, immersed in a 1:1000 solution of benzalkonium bromide for 3 to 5 minutes. Rinse with clean water and dry. It is worth pointing out that some breeders, especially the young ones, are not very aware of the importance of disinfection; some verbally have to strengthen the disinfection, but in fact have only done the disinfection of the housing or the environment, and neglected Hands, feet, clothing, tools, and other disinfection links often cause a batch of diseases, a batch of epidemics, and continuous difficulties. Therefore, we must not underestimate its harmfulness. We must heighten the attention of breeders and put them into practice in production. We must strictly adhere to all aspects of disinfection and sanitation work. Second, the development of animal husbandry in spring livestock immunization is an important means to prevent animal diseases. Pigs, cows, sheep, foot-and-mouth disease vaccine injections, immunization doses, and injection methods should be handled in accordance with the instructions. General piglet 20 to 25 days of the first time to avoid the first 2.0 ml per head, 50 to 60 days of age and then strengthen the immunization once again, 3.0 ml per head; male and female pigs fully immune spring and autumn. Immunization requirements reach 100%; chicken Newcastle disease, bursa of Fabricius, avian flu, Marek's, duck plague, gosling plague etc. are fully immunized according to immunization procedures. According to different vaccines, different inoculation methods are used at different ages. Stabbing, nasal, eye drops, nasal drinking, muscle or subcutaneous immune methods. Must follow the instructions described in the instructions to operate, immunity rate reached 100%. Conditional farms (households) recommend animal immune antibody monitoring to ensure high density, high quality, and achieve 100% immune effect.
