With the continuous improvement of the concept of large-scale and healthy farming, the natural pig raising method has become an energy-saving, environmental-friendly and efficient comprehensive pig raising technology. Since its promotion, it has shown obvious advantages and good results, and it has also been affected by the majority of farmers. Friends' wide attention and welcome. As a large animal husbandry province, Shandong attaches great importance to the promotion and application of the natural pig raising law and has increased its promotion efforts. From this issue, the Scientific Aquaculture Edition of the newspaper specially invites experts specializing in natural pig breeding research and Zhou Kaifeng, animal husbandry division of Shandong Provincial Animal Husbandry Station, to comprehensively and systematically introduce the relevant technologies of the natural pig raising law for readers' reference and application. At the same time, we also sincerely welcome the farmers to give feedback on the application of the technology and problems in a timely manner to our common exchange and improvement. contact number. --editor What is natural pig breeding? What is the comparative advantage? The "natural pig raising method" is also known as pig-breeding technology, pig-raising technique, and ecological pig-making technique. The basic approach is to set a litter pit in a pig house with a certain depth (generally 90 to 100 centimeters and a minimum height of 50 centimeters) filled with padding of agricultural and sideline products such as sawdust, rice husks, and corn stalks, using dedicated fermenting bacteria. Kind of fermentation mat production. Each finishing pig 1.2 to 1.5 square meters, 50 to 60 pigs can be kept in a pen. Pigs grow fast and have good meat quality and are popular with consumers. From the province's more than two years of experimentation and promotion, the natural pig-raising method has obvious advantages and has played a huge role in promoting pig production. The comparative advantage is mainly reflected in the following aspects: (a) solved the pig manure treatment. In the fermentation bed, pig manure was decomposed by microorganisms, there was no odor and flies in the pig house, and the environment was improved. (b) Improved pork quality. The fermentation bed is combined with a special pig house so that the pig house is ventilated and ventilated, with good lighting and temperature and humidity suitable for growing pigs. With this method pig farms, households, pig disease was significantly reduced. (c) Increased labor productivity. The natural pig-raising method can remove the litter for the first time in 1 to 2 years, and adopt techniques such as automatic feeding and automatic drinking. Reducing the sty of pigs only can save more than 50% of the labor force. One can keep 500 to 1000 pigs and 100 to 200 sows. (d) Increased pig growth rate. The microbial fermentation produces heat. The surface of the padding is 27°C to 28°C in summer, 17°C to 18°C ​​in winter, 30°C to 40°C below 10cm, and the core layer temperature can reach 50°C to 60°C. Winter and summer are beneficial to the growth of pigs. The average fattening period can be shortened by 10 to 15 days. (E) to improve the economic benefits of raising pigs. About 200 pounds of fat pigs, can save 40 to 50 pounds of feed, saving 80% to 90%, the price of commercial pigs per kilogram higher than ordinary pigs 0.6 to 1 yuan. Even without considering the factors of manpower savings, each pig can increase efficiency by 50-80 yuan. (6) To make full use of crop straws. In the process of producing organic litter by fermentation, wood chips, rice hulls, peanut hulls, corn stalks and other raw materials are fermented by a special padding fermentation microorganism and become a very good organic fertilizer. At the same time, the environmental pollution caused by farmers burning straw in Datian was reduced.
