According to incomplete statistics, in the third quarter of this year, it was reported that there were six pig farms under construction that were officially put into operation or about to be put into operation.

Let's count them carefully.

In late September, the Gu Yong pig breeding project of Zhaoqing Dinghe Agriculture and Animal Husbandry Co., Ltd., with a total investment of 400 million yuan, was officially put into operation, using intelligent building pig houses. It is estimated that the annual slaughter can reach 654.38+10,000 pigs.

In mid-September, it was reported that the pig-raising project of yongfu temple Building in Hubei Province, with a total investment of about 480 million yuan in fixed assets, entered the final stage. The project will build 9 building pig houses, with an annual output of 300,000 pigs. It is expected to be officially put into production in June 5438+065438+ 10.

At the beginning of September, the ecological breeding base of 65.438 million pigs in Wanning, Luoniushan, with a total investment of 654.38+88 billion yuan, resumed work in an all-round way, and all the buildings under construction have been capped. It is expected to be put into production at the end of February.

The base can simultaneously raise 50,000 pigs.

At the end of August, Hubei Zhongxin Kaiwei 26-story high-rise pig raising project was put into production, which triggered a heated discussion in the industry. There are two focuses in the discussion: the tallest pig building in the world and the investment of 4 billion.

It is understood that one building of this project can raise 600,000 pigs every year.

At the beginning of August, the intelligent pig-raising project of Li Anping Dong Rui Building began to be put into production. After all the projects are put into production, the annual output of pigs is 6.5438+200,000.

At the beginning of July, Longhua new pig breeding base was put into production. The base covers an area of 5,000 mu with a total investment of more than 2 billion yuan. It is planned to build 28 buildings, which is the largest single pig farm in Jiangnan at present.

The pig-raising projects in the above buildings have the nature of * * *: the investment is hundreds of millions and the annual output is tens of thousands! Although it is said that pig enterprises "have a big family business", the funds of hundreds of millions of yuan are not small. Why do pig enterprises like to "send pigs upstairs" in recent two years? Is it really to seize this vent?

Why does building pigs become an industry trend?

Since pig enterprises have invested in the construction, it shows that raising pigs in buildings is indeed profitable, and the most direct and obvious benefit is to save land.

Industry data show that raising pigs can save 80-90% of the land.

As we all know, raising pigs requires site selection and land grant. At present, under the condition of strictly observing the red line of 65.438+0.8 billion mu of cultivated land, it is not easy to get land for general pig raising projects, especially the pig raising industry without tax and pollution risks, which is usually not welcomed by local governments.

Building pig-raising projects usually requires supporting other industrial facilities, which can bring benefits to the local area and land grant will be relatively easy.

For pig enterprises that want to expand production on a large scale, "raising the most pigs with the least land" is very attractive.

The high concentration of pigs in buildings can not only save land, but also reduce the transportation cost of feed and weaned piglets to a certain extent. Moreover, due to the particularity of its management, it is necessary to rely on intelligent equipment for feeding, which can better control the feed and drinking water, thus achieving cost reduction and efficiency increase.

In addition, in the past two years, under the background of "carbon neutrality", the emission pressure of pig enterprises is great.

It is necessary to make some efforts in this regard, but it can also "reverse" reduce carbon emissions.

Taking the sewage treatment mode of the pig house on the 26th floor of Zhongxin Kaiwei, Hubei Province as an example, the wastewater and waste gas treatment system can interact, and the treated waste gas can be reused to disinfect the sewage. Ideally, the whole building can treat 654.38+100000 tons of sewage every day, reducing the carbon emission equivalent by 4 million tons.

However, all the above are the benefits of building a high-cost infrastructure for raising pigs.

According to industry sources, the cost per square meter of raising pigs is about 30% higher than that of flat-bed pig farms. No wonder pig enterprises need to invest hundreds of millions or even billions to build pig houses.

Fortunately, the construction pigsty has certain advantages in depreciation period, which can be depreciated by 15-20 years, and the cost can be shared equally.

The flat pigsty only has a depreciation period of 10- 15 years.

Under various favorable conditions, building pig raising has spread all over the country, especially in the southern mountainous areas.

However, we have also noticed that since the emergence of this pig-making model, there have been some doubts in the industry.

Is the cost and biological safety of raising pigs in buildings really a problem?

There are many problems, and we discuss several representative topics, such as "how to solve the problem of high breeding cost under ultra-high construction cost", "how to control the biosafety defense line under high-density breeding" and "how to avoid the corrosion of manure and urine in pig farms".

In terms of breeding cost, according to Jingji Zhinong, the cost of raising pigs in buildings that have been put into operation is shared, such as four links and one leveling, civil steel structure, equipment, environmental protection facilities, supporting facilities and introduction. The investment cost of a pig is about 2500 yuan.

In addition, it also announced its production achievements: in the first quarter of 2022, the delivery rate of its building breeding project in Gaozhou, Maoming, Guangdong Province was about 88%, the fattening survival rate was about 95%, and the production cost was about 14.89 yuan/kg.

Looking at the cost alone, this data is at a low level in the industry.

In terms of biological safety, it is suspected that if a pig is infected under high-density farming, tens of millions of pigs will be infected.

This is considered from the internal environment.

However, from the external environment, the building pig farm has only a small number of imports and exports, and the spread of non-epidemic diseases and other diseases can be effectively blocked through closed partition management and various technologies.

20 19 Up to now, it has been four years since pig raising in buildings, and large pig raising enterprises have already established a mature biosafety prevention and control response system.

At present, there is no clear data on the corrosion of pig farms, but builders should take this into account when designing pig farms.

Judging from the overall development trend, pig enterprises are still more inclined to enlarge the advantages of raising pigs in buildings and overcome the disadvantages.

Then, with the prevalence of building pig raising mode, will plane farming be gradually replaced?

The answer is no!

On the one hand, the construction cost of building pig farms is extremely high, which is unbearable for ordinary small and medium-sized pig farms, not to mention ordinary farmers.

On the other hand, at present, China's pig production capacity has basically recovered. Although large-scale pig enterprises are still expanding, they are limited by funds and land, and do not have the conditions for unlimited expansion in the future.

Considering the long-term development of the industry, the aquaculture industry needs to be improved and innovated, and building pigs is an attempt.

Through the continuous practice in the market, raising pigs can really promote the intensive development of pig industry, and also enable pig enterprises to greatly expand production in a certain period of time.

But the promotion of this model also needs to be fully considered. After all, raising pigs has extremely high requirements for capital, infrastructure, equipment and personnel.

On the whole, whether building pigs is a new way out for aquaculture depends on the long-term verification of the market.
