Overcoming unfavorable factors in safe pig farming in spring

The peculiar weather characteristics in spring have many unfavorable factors in the feeding and management of pigs. The unsafe factors for safe pig breeding in spring: 1. Repeated weather changes, high and low temperatures, and a large temperature difference between day and night. 2, with the gradual rise in temperature, a variety of pathogens breed. 3. The body resistance of pigs generally declined during the winter. 4. In early spring, there are many farmers who introduced seedlings and supplemented barrows. It is very easy to introduce wolves into the room. Only effective response to these unfavorable factors can reduce or eliminate the occurrence of swine diseases and ensure the safety of breeding and the benefits of breeding. First of all, we must solve the problem of heat preservation. The heat preservation in spring is still a top priority, and the temperature is variable. When cold air and rainy winds come along, we must pay attention to the details of the following insulation: (1) When it is cool or rainy or gale, we must quickly warm the pig house and add grass. . 2 To achieve "Chun Qiu Qiu Han," straw, plastic film, stoves and other insulation facilities can not be achieved too soon. Always hang curtains and check the loopholes to prevent the intrusion of thieves. 30 million attention was paid to the insulation of the delivery room piglets 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 status of the pigs. Not only do we need to do a good job of insulation, we must also do a good job of ventilation. 1 In closed pig houses, vents should be set one meter away from the ground. Every day at 1 to 3 o'clock in the afternoon, excreta and ventilating ventilation should be carried out at a higher temperature; 2 straw canopies should be covered in the vents at the roof of the greenhouse. Also do a good job inside and outside the pig house disinfection. (1) Thoroughly remove the weeds and silt around the pig dwellings and the dung ditch to prevent the growth of pathogens and mosquitoes. (2) Disinfection tanks shall be set up at the entrance of the pig farm. Disinfection basins shall be placed at the entrance of each piggery, and 2 to 3% of fire lye or 3 to 5% of Surwater shall be added. Entry and exit personnel must be sterilized. Disinfectant is added once every 2 to 3 days. (3) Thoroughly clean the door, window, ceiling, wall, pigshed and other health corners inside and outside the pig house, and spray with 2 to 3% of fire alkali solution. (4) Thoroughly clean the pig feed trough, tray, incubator, etc., then use 3 to 5 to sterilize the liquid, rinse with water, and dry it for use. (5) Foreigners and vehicles are prohibited from entering the farm. In particular, live pigs and sick pigs acquire personnel and vehicles. (6) The breeder should wear special shoes and clothes and strictly disinfect before entering the pig house. (7) Pighouses and pigs advocate the use of steam sterilization with peroxy acetic acid at a concentration of 1:500 to 1000, which can also reduce harmful gas concentrations. During the breeding process, it must be noted that it is necessary to promptly deworm the pigs. (1) To choose broad-spectrum and highly effective anthelmintic drugs of ivermectin plus fenofol. (2) When deworming the pig, remove the faeces and insecticide on the ground in time to avoid secondary infection of parasites. (3) Do worm worm worming alone. Nutrition is fundamental, nutrition is good, in order to improve body resistance. Therefore, it is necessary to strengthen the nutrition of the herd. (1) Feed the pigs with nutritious and rich feed. At present, the price of pigs is low, and some manufacturers produce and sell low-quality and low-priced feeds in order to cater to the appetites of pig farmers. These products must not be used cheaply. Otherwise, the pigs will suffer from malnutrition, poor growth and easy onset. (2) Pig farmers using self-ingredients must ensure the quality of raw materials, in particular, do not use water with excessive water content 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 formulating without authorization due to low pork prices. (4) Temperatures in the spring are gradually warming and the weather is humid. It is a season for the proliferation of various mycotoxins. Pay attention to the “three defenses” of feed: prevent rain, moisture, and mildew, and control the mycotoxin hazards from various sources. (5) There is a lack of green feed in early spring, and it is recommended to give sows a suitable amount of green and juicy feed, such as green leaves and carrots. (6) Appropriate amounts of Chinese herbal medicine and living seasonings are added to the feed in order to correct the disease and promote good health. Such as honeysuckle, ginger, green onions, garlic, vinegar and so on. (7) Regularly adding micro-ecological products such as prebiotics and yeast polysaccharides to the feed to regulate the gastrointestinal tract, improve gastrointestinal function, and prevent and treat various diarrheal diseases.
