Economic circulation method of pig industry

Abstract

The invention provides an economic circulation method of pig industry, which solves the problem of manure treatment in pig farms, changes wastes into valuable substances and greatly lowers the cost consumption. The method utilizes the manure to produce the energy sources and fertilizers, and adopts the economic model of self supply of energy sources and feeds. The method comprises the following steps: S1. respectively establishing a cultivation farm and a plantation, wherein the cultivation farm is used for breeding pig herds, and the plantation is used for planting feed raw materials; S2. collecting the cultivation farm manure, and carrying out marsh gas fermentation treatment; S3. collecting marsh gas, and carrying out harmless treatment; S4. establishing a marsh gas energy supply mechanism to put the marsh gas into use as an energy source; S5. carrying out dry-wet separation on the marsh gas fermentation residues, and collecting the liquid substance and solid substance; S6. irrigating the plantation by using the liquid substance as a liquid fertilizer to enhance the nutrients of the soil; S7. producing an organic fertilizer by using the solid substance as the raw material; S8. cultivating the feed raw materials by using the organic fertilizer; and S9. producing the feed by using the feed raw materials, and feeding the pig herds.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to an economic cycle method for pig raising. Background technique [0002] Breeding is an important part of agricultural production, especially pig farming, which can not only increase income, but also provide people with meat and raw materials for the food industry. The pig industry is a very important industry, especially in China, where the pig industry has occupied a position that cannot be ignored in the national economy. [0003] At present, there are several problems that need to be solved urgently in the development of the pig industry: 1. Large amount of excrement discharge, high cost of purification treatment, serious environmental and air pollution, and unqualified breeding environment leads to high incidence of pig herds and high risk of breeding 2. The larger the scale of the pig farming industry, the higher the energy consumption, and the high cost of energy ...

Problems solved by technology

[0003] At present, there are several problems that need to be solved urgently in the development of the pig industry: 1. Large amount of excrement discharge, high cost of purification treatment, serious environmental and air pollution, and unqualified breeding environment leads to high incidence of pig herds and high risk of breeding ; 2. The larger the scale of the pig farming industry, the higher the energy consumption, and the high cost of energy input; 3. The feed purchased directly may not be suitable for the needs of the pigs, the feed consumption is large, the conversion rate is low, and the output and input are difficult to achieve ideal
