Zero-emission pig breeding in biological fermentation beds is a new technology introduced from abroad in recent years. It mainly uses the aerobic fermentation of biological bacteria to solve the zero discharge of excreta, saves labor, saves electricity, saves water, saves land, achieves environmental remediation, improves pig disease resistance and meat quality, and is commonly referred to as “ Lazy people raise pigs. For this new practical technology, Lishui City Livestock Veterinary Bureau has organized technical personnel to visit Fujian and the province's Ruian, Jiaxing and other places to study their experience and feel that this new technology has indeed played a role in promoting the development of ecological pigs. After the inspection came back, an adaptation test was conducted in response to the actual hot weather in Lishui in the summer, and preparations such as decolonization, immunization and the like of the sheds, litter, strains, and test pigs were immediately performed. A few days ago, six bio-fermentation beds had been produced in Lishui City's animal husbandry thoroughbred field, and it was possible to invest in trials recently. According to local experience, the technology can increase the feed conversion rate, save about 10% of feed annually, save more than 90% of water, and save more than 60% of labor. The fermentation bed can be used continuously for 2-3 years at a time. The litter can be used directly as organic fertilizer. Clean environment, pig health, improve meat quality. Land is saved and excrement really reaches zero emissions. After the successful testing of this new technology, it will be applied as a key promotion model for the construction of an ecological-scale pig farm in pig farms where the city, especially the excreta disposal site is limited. The function of the reaction frame is to transmit force. Go to the floor and use it to test samples with hydraulic actuators. The size of the reaction frame or part of this frame will be used for most major experiments in the laboratory. Because the geometry of future experiments is unknown, the reaction frame has been designed as a reconfigurable frame that can apply forces at different height levels or vertically from above.
