With the further development of pig dly project, the number of peasant households in our county is increasing, and the need for scientific pig raising technology is more and more urgent. In order to make pig farming more scientific and produce good economic benefits, The scale pig farmer should also grasp the following points of technical measures: 1. Site selection for the farm. The address of the farm should be chosen to be sunny, flat, easy to drain, away from traffic routes and densely populated areas. 2, pig house construction. To pay attention to scientific architectural design, peasant households can use specific or single-row pig houses according to their actual conditions. The overall requirements for the pig house construction are that the pig house is cool in winter and cool in summer, and the area and the shuttle are spacious, with clear ventilation, the height of the pig house is more than 2.6 meters, and the roof is brightly tiled to increase the brightness. 3, pigsty construction. Pork floor and wall construction materials should be sturdy and durable, generally using triple land surface and brick walls. Breeding pens should be spacious and bright, with an area of ​​8 square meters (except for breeding pigs and commercial pigs with limited feed bar). The ground is flat and smooth, with a certain degree of slope. There is a leaky seam floor in the circle, which is easy to flush the ears and clear the excrement to ensure the cleanliness of the house. Automatic drinking fountains are installed in the circle to ensure that the pens are dry and the pigs can fully drink clean drinking water, reducing labor intensity. Sow litter sets up piglet incubators to increase the survival rate of piglets, and a piglet nursery ring is also built. 4, do a good job of water supply system construction. Large-scale swine production, drinking water, domestic water, clean water, loud ears, listen to water, etc., have a large amount of water. Pig farmers need to build water towers and do a good job in tap water supply and sales water system construction. 5, manure treatment. Large-scale swine production, excrement removal and disposal are very important. It is necessary to vigorously promote the storage and sterilization of biogas tanks, implement harmless production, and promote the use of biogas to save energy and protect the environment. 6, fully consider the layout of the building. When constructing a pig farm, people's living quarters and pig houses should be separated by a certain distance, generally more than 50 meters. In order to ensure the safety of people and livestock, according to the characteristics of the wind direction, people's living quarters are built on top of the wind, and the middle part is pig houses. The isolation treatment of the waste disposal area and the sick pigs is built in the next direction. 7, do a good job in file management. For large-scale swine production, records of archival materials, such as pedigree files of breeding pigs, litter records of sow mating, disease and epidemic records, and prevention and control programs and treatment results, records of pigs entering and exiting, pig farms and production operations, etc., should be well documented. Guide future production and management. 8, the advantages of pasture planting. Large-scale pig production is mainly based on formulated feeds, supplemented by green feed. Therefore, we must fully consider the cultivation of high-quality forage grasses, such as ryegrass, comfrey, chicory, and red vine, in order to supplement the needs of pigs with vitamins and water. 9. Anti-epidemic measures. Large-scale pig production, due to the large number of pigs, the high density of pigs, pigs in and out of the frequent, health and epidemic prevention work is very important. It is necessary to formulate strict disinfection measures, do a good job in environmental sanitation and disinfection, and prevent the invasion of pathogens. The pig farm should be strictly sterilized in the ordinary times, and the epidemic-prone season should pay attention to strengthening the disinfection. The disinfectant can use quicklime, plant ash, and caustic soda. We must do a regular epidemic prevention epidemic according to scientific immunization procedures, carry out epidemic prevention for swine fever every spring and autumn, and we must do a good job of preventing epidemics such as parvovirus, pseudorabies, and E. coli. Piglets also need to make good piglets. The epidemic prevention of diseases such as paratyphoid fever and yellow piglets and other diseases of piglets should be strengthened during the epidemic season.
