The technical principle of pig breeding in fermentation bed

The use of some highly efficient and beneficial microorganisms and litter in a pig house to build a fermentation bed. The pigs directly discharge the excrement on the fermentation bed, using the pig's arch excavation habits, and artificially assisted turning over of the pig manure, urine, and bedding. Fully mixed, through the decomposition and fermentation of beneficial fermentation microbial colonies, the pig manure and urine organic substances are fully decomposed and transformed. The technical principle of pig breeding in fermentation beds is basically the same as the principle of decomposition of organic fertilizers in farmland. The key is the selection of the ratio of carbon to nitrogen in the litter and the fermenting microorganisms. The core of its technology lies in the construction and management of the "fermentation bed." It can be said that the efficiency of the "fermentation bed" determines the economic efficiency of the pig-raising method.
1. Using the principles of air convection and solar elevation angles, local construction of pig houses makes full use of the air flow in different seasons to build pig houses. The pig houses are equipped with adjustable ventilation facilities such as shutters to control the air flow and flow rate of the pig house. The roof of the pig house and the windows should fully consider the rules of the sun.
2. Use bio-fermentation principle to treat excreta to solve the problem of environmental pollution Due to the continuous growth and reproduction of fermenting microorganisms, the excreta produced by pigs is rapidly decomposed to achieve the effect of treating excrement.
3. Using the greenhouse and pavilion effects to improve the somatosensory temperature of the pigs, the insulation curtains will be lowered in winter. The whole pig house becomes a greenhouse, and the fermentation bed will also generate considerable heat, which will improve the abdominal temperature of the pigs. Similarly, in the summer, the pigs felt very cool because of the effect of similar pavilions such as sweeping winds, drafts, etc. due to the almost open windows.
4. Using the principle of occupation of beneficial bacteria to enhance the disease resistance of pigs, raise the efficiency of breeding and the quality of pathogenic bacteria on the basis of the quality of pathogens. The pathogenic bacteria reach a certain concentration, due to the proliferation of beneficial microorganisms such as fermenting microorganisms, on beds, air In every corner of China and even in pig houses, beneficial bacteria are permeated, making beneficial bacteria the dominant bacteria and forming a natural barrier against pathogens. Even with the stimulation of a very small amount of pathogenic bacteria, the pigs can only produce a specific immune response, so that the pigs can form a strong protective force.
In a word, the fermentation bed pig raises new requirements for pig house construction, feeding and management, bio-safety system construction, diet preparation, disease prevention and control, etc. on the one hand, and on the other hand it provides good fermentation microorganisms The cultivation conditions allow them to quickly absorb the excreta of the pigs. On the other hand, they must also ensure that the pigs are provided with a good living environment to meet the needs of the pigs in different seasons and physiological stages so as to increase the breeding efficiency.
