With the increasing requirements of environmental protection in aquaculture industry, the comprehensive utilization of chicken manure and sewage needs to realize the trinity of government, enterprise and market, establish an operation mechanism with enterprise investment as the main factor, appropriate government support and active participation of social capital, improve the agricultural subsidy system guided by green ecology, give full play to the decisive role of market in resource allocation, guide and encourage Encourage social capital investment, cultivate and develop the industry of breeding waste resource utilization.

在的大环境下，养殖户要及时了解的畜牧业养殖政策，自己找十三五畜牧养殖规划来看看，否则逆天而行只能被淘汰，对抓的越来越严，不少地区没有取得环评的养殖场被勒令关门停业。对于大型养殖场来说，上一套粪污处理设施并没有太大压力，但是大猪预混料对于散户来说，这一套粪污处理设施便可能耗尽所有资金。万一环评不过关便要关门停业，这对散户来说是致命打击。

In the environment of environmental protection, farmers should timely understand the state's animal husbandry and breeding policies, and look for the 13th five-year plan for animal husbandry and breeding. Otherwise, they will only be eliminated if they go against the weather. The state pays more and more attention to environmental protection. Many farms that have not obtained the EIA in many areas have been ordered to close down. For large-scale farms, the previous advanced sewage treatment facilities are not too much pressure, but pig premix for retail investors, this set of sewage treatment facilities may run out of money. In case the EIA fails, it will close down and close down, which is a fatal blow to retail investors.

另外管理和技术也是散户的一个弊端，举一个简单的例子，从母猪产仔到肉猪出栏，大猪预混料几家散户可以做到全程对生猪进行跟踪记录档案，顶多就是记一下哪窝猪仔打了那些疫苗，等进入育肥阶段之后更是基本没有任何资料。虽然养殖散户拥有多年的养殖经验，但是技术仍然不比大型养殖场，各个环节专人负责，各司其职，效率非常高。

In addition, management and technology is also a disadvantage of retail investors. For a simple example, from sows to meat pigs, several retail investors can track and record the whole process of pig production. At most, they can record which litter of piglets were vaccinated. After entering the fattening stage, there is basically no information. Although individual farmers have many years of breeding experience, their professional technology is still no better than that of large-scale farms. Each link is in charge of by a specially assigned person, and the efficiency is very high.
