Pig industry is an important industry in China's agriculture. It plays an important role in ensuring the safe supply of meat, and large-scale pig farming is easy to breed a lot of germs.

How much does it cost to build an environmentally friendly pig farm now?

Take the pig farm in Jiangshan City, Quzhou as an example:

1. The specification of the fermentation bed of the pig farm is 42m*24m*1.4m. The fermentation workshop covers an area of 1000 square meters (including more than 200 square shifters and sewage collection tanks). The civil construction cost is about 300 yuan per square meter. The total volume of bedding material 1036m3, about 40m3 fermentation bed, can treat 1 ton of sewage.

2. The fermentation mattress material is composed of grain hull, sawdust and bacteria. The ratio of chaff to bacteria is 6: 1. The fermentation mattress material needs 250 grams of bacteria.

3. The market price of chaff and sawdust is 400 yuan per ton, and the market price of 250 grams of bacteria is about 15 yuan. The monthly consumption of bacteria is 10 grams per cubic meter (0.3-0.4 yuan per pig). The whole set of flipping and throwing machine is more than 200,000 yuan, running for 3 hours / day, total power 22KW. There are one sewage pump, one sewage pump, one sewage collection tank and one homogenization tank respectively, with an artificial monthly salary of 3-4 thousand.

What are the site selection conditions and matters needing attention for pig farms?

The choice of the address of pig farm is the primary task of building pig farm. The proper location of pig farm and reasonable architectural planning and layout can not only facilitate production management, but also give full play to the benefits of pig raising. The site selection of pig farm should pay attention to the following five aspects:

1. Topography and topography: the overall requirements of the site are high and dry terrain, good drainage, leeward to the sun, neat and open terrain, the ground should be flat and slightly gentle slope, the slope should be 1% to 3%, the maximum should not exceed 25%. To have sufficient area, it is generally considered that each sow can reproduce 40 square meters and commercial pigs 3 square meters.

2. Water source and water quality: sufficient water quantity and good water quality are required (in line with drinking water hygiene standards).

In large-scale pig farms with dry manure removal process, the total water supply should not be less than 20 tons per 100 basic sows per day (hot seasons and dry areas can be increased by 25%).

3. Soil and soil quality: Sandy loam is the most ideal, which is beneficial to the health and epidemic prevention of pigs.

4. Power supply and transportation: adequate power supply is required. In general, large pig farms should be supplied by secondary power supply network and equipped with generators. Pig farms should be selected in places with convenient transportation, more than 1000 meters away from the trunk lines (railways, national highways and provincial highways), more than 500meters away from the main roads, and not less than 50,100 meters away from rural roads. For small and medium-sized pig farms, the above distance can be appropriately smaller, but not less than 100 meters from the traffic trunk line, and the pig houses of professional pig farmers should also be more than 20 meters away from the residence.

5. Surrounding environment: pig farms and villages and towns, factories and other livestock and poultry farms should maintain a proper distance to avoid mutual pollution. General pig farms should be more than 500m, large pig farms should be more than 1000 meters. Within 1000 meters, there are no chemical plants, slaughterhouses, tanneries, paper mills, mines and other enterprises that can easily cause environmental pollution. In recent years, more and more people have returned to the countryside, and they urgently need to find land to do projects in rural areas. As a result, "land brokers" have been derived. "Land brokers" mainly earn intermediary fees from growers or investors. At present, Tuliu Group is recruiting land transfer service providers and setting up land transfer service centers across the country.
