The basic idea of pig industry is to make full use of pig biology. The reason is that China's agriculture is still dominated by growing grain, and the cost and price of growing grain are very high, and many nutrients are rich. Not only pigs, sheep, cattle and other animals can be raised, but also various animals can be used as much as possible in human daily life, that is, biogas fermentation is the core of pig ecological breeding.
Therefore, at this time, livestock and poultry breeding is abandoned, and pig ecological breeding is a "planting and breeding" mode or "biogas breeding cycle", which can mobilize great enthusiasm. In the past, the scale of raising pigs was small, and pig manure was directly used in agriculture, which would not cause pollution! However, with the expansion of pig farms, there are more and more idle laborers in rural areas. Let's talk about the advantages of ecological pig raising in ordinary rural areas.
It solves the problem that manure is difficult to treat in pig production, turns waste into treasure, improves the rural ecological environment, reduces the use of chemical fertilizer, relieves the pressure, improves the ecological breeding of pigs, and is conducive to providing high-quality and nutritious meat food; This model can effectively solve the long-standing contradiction between the development of pig industry and environmental protection, and promote the comprehensive pollution of resources; Conducive to reducing pig diseases; Conducive to improving the quality and taste of meat; Conducive to expanding export trade; Suitable for transporting animals.
