13-storey hotels in thousands of pigs in southern China are considered a safe livestock model in front of African pigs.

In a 13-storey small-scale apartment building in southern China, more than 10,000 pigs are captured in tight security conditions.

This luxury pig farming model is a modern biosafety approach, in which pigs, main meat in China, protected from viruses, including African pig rauling has a halve

Called the Pig Hotel, these giant vertical farms are being built by many companies, including Myuan and New Hope Food Company, which apply strict control measures for each large livestock

China is copying the best model of Europe and America to narrow the biosafety distance, according to Rupert Claxton, Director of Gira meat consulting firm based in the UK, who has advised many shallow

For 20 years, China has done what Americans took 100 years to do it, he said.

African pig cholera causes dead pigs a series of fierce outbreaks in China in 2018. In a year, about half of the pigs of more than 400 million pigs in China are wiped out, more than US pork's porkers and

Food security becomes a top priority, and when prices have increased to the highest level in 8 years, the Chinese government must open an emergency frozen meat stockpile to lower prices.

To date, China's pig restoration is faster than expected, when super farms constantly increase livestock capacity.

However, the threat from the target of African pigs still exists, with 11 clusters of outbreaks in the first 6 months of 2021, causing more than 2,000 pigs being destroyed, according to the Chinese Ministry of Agriculture data in July.

In developed countries such as the US, Denmark and the Netherlands, countries with the best biosafety standards in the world and have never recorded a recent African pig outbreak, a few companies

Today, large complexes of pig raising are one of China's food security pillars.

As of 2020, 57% of China's pig production comes from farms that provide more than 500 pigs per year.

New Hope Group recently completed three 5-storey buildings on an area of about 140,000 m2 in Binh Coc District in East Beijing.

According to Gong Jingli, factory monitoring, facilities equipped with robot monitoring animal body temperature, air filter, automatic feeding and sterilization system, do not allow outsiders to visit for safety reasons

Large-scale means greater risk, when thousands of pigs are captured in the same place that can spread rapidly infectious diseases.

Tom Gillespie, American veterinarian with more than 40 years of experience, said he was asked to remove wedding rings but was allowed to wear glasses when visiting a livestock base in China.

Some large farms also build dormitories for workers to minimize workers exposed to outside, the strategy that Gillespie said it would be difficult to implement in other countries.

In Europe and America, we are limited to the scale of pig farms because people don't want to live near these huge facilities, Claxton said.

Expanding vertical space is a popular choice in countries that lack area.

High-rise farms can reduce 30% of agricultural land use area compared to traditional farms with the same size, construction positions are also flexible by can be arranged in the mountains, according to Gong, monitoring of

Muyuan, China's largest pig breeding company, said land fund for 100 million pigs.

The number of large-scale pig farms in China increased also reflects the change in the diet of the people.
