High pork prices in the northeastern province of Jilin is prompting farmers to raise pigs to reach an average weight of 175 kilograms to 200 kilograms, higher than the normal weight of 125 kilograms. They want to raise them “as big as possible,”said Zhao Hailin, a hog farmer in the region. The trend isn’t limited to small farms either. Major protein producers in China, including Wens Foodstuffs Group Co, the country’s top pig breeder, Cofco Meat Holdings Ltd. and Beijing Dabeinong Technology Group Co. say they are trying to increase the average weight of their pigs. Big farms are focusing on boosting the heft by at least 14%, said Lin Guofa, a senior analyst with consulting firm Bric Agriculture Group. The average weight of pigs at slaughter at some large-scale farms has climbed to as much as 140 kilograms, compared with about 110 kilograms normally, Lin said. That could boost profits by more than 30%, he said.
