Technical Field

The invention relates to the technical field of ecological safety pig raising, in particular to a commercial pig safety production system.

Background

With the increasing prominence of breeding epidemic situation and environmental protection problems, the demand of the ecological controllable breeding farm is increasing. The ecological pig raising is to organize each production link by utilizing the ecological principle, so that the structure of a pig production system reaches the optimal degree, the biological production potential can be fully exerted, the natural production process is utilized to the maximum extent, and the investment of artificial chemical substances and mineral substances is reduced. The method makes full use of land, water surface and various feed resources according to local conditions in pig farm address selection and feed organization, so that a farming (animal husbandry) production system taking pigs as a core realizes virtuous circle, thereby greatly improving the utilization rate of natural resources. The ecological pig raising method has the advantages that excrement and urine sewage generated in the pig raising production process is returned to the field in a certain way, organic fertilizers are provided for various planting industries such as grain crops, feed crops, vegetable crops, fruit forests and the like, and accordingly the development of the pig raising industry is gradually promoted. The developed pig raising industry provides more organic fertilizers for the planting industry. This results in a good cycle of interdependent, mutually promoting organic. The pig raising industry and the planting industry are organically combined, so that the comprehensive productivity level of agriculture is improved, and the stability of an agricultural production system is enhanced.

At present, a large number of microorganisms of various types exist in most farms, wherein pathogenic microorganisms often cause animal diseases and endanger the health of workers in the farms, the pathogenic microorganisms can be horizontally transmitted through various facility devices and can also be vertically transmitted through excrement and urine, instrument facilities in a colony house, including floors, walls, roofs, fans, windows and the like, are important carriers of the pathogenic microorganisms, and small animals, mosquitoes and flies entering from the outside of the colony house and even air can carry the pathogenic microorganisms to cause the animal diseases. Most of the existing pigsties adopt longitudinal ventilation, under the ventilation mode, the wind speed distribution in the pigsties is uneven, ventilation dead angles exist easily, air flows in the whole pigsties, the infection probability and the prevention difficulty of infectious diseases such as swine fever are increased, and the economic benefit is low.

Meanwhile, the industry encourages to adopt a method of ectopic fermentation of excrement in recent years, a large amount of pig manure generated by most pigsties in the existing pig farm needs to be manually cleaned at regular time, then the pig manure is transported to a fixed place by a vehicle for fermentation, the method needs a large amount of manpower, and the amount of harmful gas released into the pigsties by the excrement is completely dependent on the cleaning times, and the environment in the pigsties is often poor.
