Description

Technical Field

[0001] The invention belongs to the field of liquid fermented feed, in particular to a green and low-cost liquid fermentation feeding system. Background Art

[0002] Pig farming is an important industry in my country's agriculture and plays an important role in ensuring the safe supply of meat. my country's pig farming is transforming from traditional pig farming to modern pig farming. Most of the current domestic pig farming methods use dry feed and cold water, and a small part uses wet mixed feed. Pigs fed in the above way often have the following problems: easy diarrhea, difficult digestion, low immunity, slow growth, etc. Because of the above problems, many domestic pig farmers now use a large amount of antibiotics in food to solve the problem. A large amount of antibiotics will cause the feed to contain too much copper and zinc, and high copper and high zinc pig feed will produce serious heavy metal pollution, which is very unfavorable to the growth of pigs.

[0003] At present, there are methods for feeding pigs with liquid feed in China. The applicant introduced a feeding system for liquid feed in the patent number: 201710269411.4, and the patent name is: A liquid fermentation automatic feeding system and feeding method. It can automatically feed and improve feeding efficiency, and also has the following advantages: (1) the digestion and absorption rate of food by pigs is greatly improved; (2) the immunity of pigs is improved and they are not easy to get sick; (3) the anti-diarrhea ability is greatly enhanced; (4) no antibiotics are added to the liquid feed, avoiding heavy metal pollution such as high copper and high zinc; (5) the growth rate and survival rate of pigs are greatly improved. However, in the actual long-term use, due to the use of more electronic components, the equipment cost is high and it is easy to fail and increase the maintenance cost. At the same time, since the temperature control device needs to be continuously powered on to maintain the temperature, the energy consumption is high and the operating cost is increased. For the above reasons, it cannot be widely promoted and applied. Summary of the invention
