China’s pig farms battle new surge in African swine fever

A surge in African swine fever infections in China is set to reduce hog output later this year, farm managers and analysts said this week, pushing up prices in the world’s top pork consumer as demand recovers.

The incurable disease has plagued China for years, with an initial wave during 2018 and 2019 killing millions of pigs and leading to a dramatic decline in meat output that roiled global markets.

Infections this year began to surge relatively late in the season, around the Lunar New Year holiday in January, when millions of people travelled after China had relaxed its COVID curbs, said three managers at pig farming companies and analysts.

“Data from swine fever virus testing companies show that the number of positive detections exploded after the new year holiday. The order of magnitude in a single month has reached the level of the whole year of 2022,” said analysts at Huachuang Securities in a report.

“We guess that the current swine fever infection area in northern production areas may be reaching 50%,” it added.

Northern provinces such as Shandong and Hebei are among the top producers of hogs.

A senior manager at one of the country’s top hog producers agreed with the estimate.

“We do see quite a lot of new infections in March. We feel it hasn’t ended yet, that’s the problem,” he said, declining to be identified due to the sensitivity of disease outbreaks in China.

Hard to assess

Chinese farms typically do not report disease outbreaks to the government, making it challenging to get an accurate picture of the extent of the infections. The Ministry of Agriculture and Rural Affairs did not immediately respond to a request for comment.

The impact of the outbreaks depends on how early they are detected and how they are managed, said the pig company manager.

A milder form of the virus that has few clinical symptoms is common, making it challenging to detect, he added.

Chinese hog prices have hovered around 15 yuan ($2.18) per kilogramme since late last year, pressured by weak demand and excess supply.

Large losses last year encouraged many farmers to downsize herds in the winter, which has pushed up slaughter volumes.

Infected pigs sent to slaughter could also be weighing on the price, said Jim Long, chief executive of Canadian genetics company Genesus, which sells breeding pigs in China.

“We continue to believe the low China hog price is due to many pigs going to slaughter at any weight due to ASF [out]breaks,” he wrote in a report this week.

The disease outbreaks, as well as the prior herd reductions, will lead to fewer hogs reaching the market when demand improves in the second half of the year, said the Huachuang report.

Though not as serious as in 2019, the disease could reduce production by more than 10%, Huachuang analyst Xiao Lin told Reuters.

“It is serious in some provinces but not across the country,” said Pan Chenjun, senior analyst at Rabobank, who estimated “around 10%” of production could be impacted.
