Pig farming doesn't make money, so look back at the fields - what insight does this rural proverb offer?

Thanks for the invitation! If you like it, please remember to like and follow!

In rural areas, the traditional family-style pig farm, with pig farming and crop growing combined and pig manure recycled, has no pollution problem! In the past, China was dominated by a smallholder economy, and land was the foundation of survival! Pig farming could only be regarded as a "sideline"! Raising pigs was not for the pigs themselves, but only for pig manure to fertilize the fields! This was also a drawback of our traditional agricultural development over several thousand years! Now, in the new era, pig farming is no longer limited to the benefits of the pigs themselves, and obtaining benefits from composting manure has become widely recognized!

In recent years, China's economy has developed rapidly, and the people's material and cultural life has gradually improved! The demand for quality of life is also constantly rising! The supply of meat products is also continuously increasing! By comparison, the scale of pig farming is also constantly expanding, especially since pig prices have kept rising in recent years, and the phenomenon of rural residents following the trend in pig farming has been serious! In some areas, pig farmers have weak awareness of environmental protection, and pollution problems from pig farms emerge one after another! Since 2016, a "storm" targeting the treatment of farming pollution has swept through the pig farming industry! It is uncertain whether the vast number of small rural pig farmers will leave or stay! The only certainty is that the waste from pig farms must be treated!

In fact, isn't this just like the principle contained in the rural proverb "Pig farming doesn't make money, so look back at the fields"? The only difference is the scale of pig farming! Traditional pig farming took the family as the unit, with a small farming scale, pig manure was easy to handle, and the family farmland could directly absorb it! Today, however, most pig farmers no longer grow crops, and those who grow crops do not raise pigs! Thus, on one side resources pile up and pollute the environment, while on the other side people eagerly await land that lacks fertilizer! What is missing in this phenomenon is the resource-based treatment and utilization of pig manure!

At present, the mainstream manure resource treatment models for pig farms can be roughly divided into two types:

1. Circular planting and breeding, ecological return to the fields!

This model of resource-based treatment of pig manure is roughly the same as the traditional combination of pig farming and crop growing with pig manure returned to the fields, and the difference is scale! Large-scale pig farms must have land with a matching capacity to bear the waste! After pig farms carry out "three separations, two modifications and reuse," pig manure undergoes microbial anaerobic fermentation, and biogas is used for daily life or biological power generation! The biogas residue and biogas slurry are used for agricultural planting, so as to bring into play the economic benefits and social and ecological benefits of pig farming!

2. "Turning waste into treasure" aerobic composting

Pig manure is a high-quality raw material for producing organic fertilizer! Pig manure composting is not only a zero-discharge project for manure in pig farms, but also another channel for broadening the income of pig farms! It has been widely promoted not only in large-scale pig farms but also among small rural pig farmers! This article will not describe it in detail; pig farmer friends who are unclear can follow me, as I posted some techniques on ectopic fermentation bed composting a few days ago!

In short, most rural proverbs are rough in wording but not in reasoning. For our contemporary pig farmers, whether rural or large-scale pig enterprises, "Pig farming doesn't make money, so look back at the fields" still has practical significance! If pig manure is handled well, how could there be no money to be made! In fact, this is also the key to building a sustainable pig farming economy with "integrated planting and breeding and circular agriculture and animal husbandry"!
