The temperature in spring is high and low, and there is a large temperature difference between day and night. With the gradual recovery of temperature, various pathogens breed and become active. Farmers should pay attention to the following points when raising pigs in the spring. Ventilation and insulation 1. In the event of cooling or rainy windy weather, it is necessary to warm the pig house quickly and add grass. 2. To achieve the "Spring Festival", straw, plastic film, stoves and other insulation facilities can not be withdrawn prematurely. Hang curtains at any time to check the loopholes and prevent the intrusion of thieves. 3. Pay attention to the insulation of production house pigs and nursery pigs, especially the effective temperature of the abdomen. 4. There is a large temperature difference between day and night in the north, and it is necessary to adhere to the night patrol system and regulate the temperature of the housing at any time according to the condition of the herd. 5. Closed-type pig houses shall be provided with vents at 1 meter from the ground. Daily excrement and ventilation shall be conducted at 1 pm to 3 pm when the temperature is high; the straw vents at the roof of the piggery will be covered with straw curtains at night. Pighouse disinfection inside and outside 1. Thoroughly remove the culprits around the pig house and the weeds and silt from the ditch to prevent the growth of pathogens and mosquitoes. 2. There is a disinfection pool at the entrance of the pig farm. Disinfect pots are placed at the entrance of each pig house. Add 2% to 3% of fire lye or 3% to 5% of the Surwater; workers must be sterilized every 2 days to 3 days. Add a disinfectant once. 3. Thoroughly clean the door, window, ceiling, wall, pigshed and other health corners inside and outside the pig house, and then spray with 2%~3% fire alkali solution. 4. Thoroughly clean the pig feed trough, tray, incubator, etc., and then use 3% to 5% to sterilize the liquid. Rinse with dry water and dry. 5. It is forbidden for outsiders and vehicles to enter the farms, especially live pigs and sick pigs as well as acquisition of personnel and vehicles. 6. The breeder should wear special shoes and clothing and be strictly sterilized before entering the pig house. 7. Pigs and pigs are encouraged to use fumigation with peracetic acid at a concentration of 1:500 to 1:1000, which can reduce the concentration of harmful gases. De-worming pigs 1. Select broad-spectrum and highly effective anthelmintic drugs for ivermectin plus fenofol. 2. When removing insects from pigs, remove manure and ground insecticides in time to avoid secondary infections by parasites. 3. Do a worm worming alone. Strengthen nutrition and improve herd resistance 1. Can't use low-quality, low-cost feeds cheaply, otherwise it will lead to malnutrition, poor growth, and proneness to disease. 2. Pig farmers using self-ingredients must strictly control the quality of raw materials, in particular, do not use excessive moisture and moldy corn. It is recommended that corn be sieved prior to use to remove impurities. 3. Do not change low-quality raw materials or formulate feeds without formulas due to low pork prices. 4. As the temperature in the spring gradually warms up, it is necessary to pay attention to the “three defenses†of feed, that is, prevent rain, moisture, and mildew, and control the damage of mycotoxins from the source. 5. The lack of green feed in early springs encourages sows to be fed with green and juicy feed, such as green leaves and carrots. 6. Appropriate amount of Chinese herbal medicine and living seasonings are added to the feed in order to restore the health of the pigs and prevent diseases. Such as honeysuckle, ginger, green onions, garlic, vinegar and so on. 7. In the feed regularly add micro-ecological products, such as probiotics, yeast polysaccharides and other conditioning gastrointestinal tract, improve the gastrointestinal function of pigs, prevention and treatment of various diarrheal diseases.
