BEIJING (Reuters) - With China's Lunar New Year festivities fast approaching, pig farmers in the world's biggest pork market have little to cheer. As they fatten herds to meet peak demand, a slump in retail prices and a spike in feed costs are grinding up profits.
A wave of imports has squeezed pork retail prices 10 percent since they hit record levels in June on a domestic supply shortage. Meantime, the price of soymeal has hit a 2-1/2 year high in Sichuan JCI-SBM-CHDU as farmers buy up stock to feed up pigs for the New Year "golden season".
As Chinese consumers tuck into cured pork and stews for the holidays - starting in late January this year - farmers will have to soak up profit margins that have halved in six months during a buying spree that accounts for a quarter of annual pork consumption.
While profits are still close to historically high levels, the fall comes on top of food safety scandals and belt-tightening as economic growth stalls. China's pig farmers also face a growing concern: appetite for what is traditionally the country's favourite meat is waning in favour of cheaper alternatives like mutton and poultry.
"We're in the hottest season for pork consumption...but the scale of the increase (in demand) is lower compared with previous years," said Feng Yonghui, analyst with pork consultancy Soozhu.com.
In Sichuan, China's largest pig farming province, accounting for 10 percent of national pork production, profit margins JCI-HOGM-SICH have slumped 45 percent to 650 yuan per pig since May, when they touched their highest on records going back to 2009.
Feng expects profit margins nationwide to average 300-400 yuan per pig next year. That's well up from the average of the past five years, but down from bumper levels earlier this year.
In the eastern province of Shandong, meanwhile, some are bracing for things to get worse.
"2016 was a money-making year," said one Shandong farmer with 1,000 breeder pigs, speaking on condition of anonymity. "And in 2017, it's likely going be loss-making. Many dare not expand the herds even if they are making profits now."
An estimated 140 million pigs will be slaughtered in the two months leading up to the week-long New Year holiday, making that period the busiest months of the year accounting for 20 percent of the annual average total.
Yet that comes as weekly average national pork prices hover around 28 yuan ($4.03) per kilogramme, close to their weakest levels in calendar 2016.
Higher costs of feed compound the headache for breeders like Guangdong Wens 300498.SZ, the nation's largest, in the months before herds head for slaughter.
On average, the nation's pigs will gobble up about 90 kilograms of feed apiece in the two months leading up to the Lunar New Year, costing farmers a whopping 38 billion yuan ($5.47 billion) in rations based on a 50:50 mix of soymeal and corn, according to Reuters' calculations.
As demand climbed ahead of the winter, depleting supplies, national soymeal feed inventories CFD-SBMST-NATN have dropped to their lowest in three years at 363,500 tonnes.
Farmers can switch to other feed mixes, but the cost of possible replacements like sorghum, distiller's grain and rapeseed meal have also risen lately.
Analysts expect pork prices to remain under pressure well beyond the new year holiday as meat supplies grow, with farmers replenishing herds and imports rising.
"This spring festival (Lunar New Year), farmers can still get a relatively good price for their herds, but maybe not next year," said Soozhu.com analyst Feng.
