Lean hog futures are facing selling pressure due to rising feed costs and declining pork exports, particularly to China. Despite these challenges, cash hog and fresh pork prices are rising, and supplies in cold storage are providing a buffer for reduced numbers. China's pork production has increased by 31.9% year-over-year in the first quarter of 2021, but African swine fever continues to temper expectations on the speed of the hog herd rebuilding. China's Ministry of Agriculture and Rural Affairs has released guidelines to reduce the use of corn and soymeal in hog and poultry feed, and has divided the country into regions to prevent and control animal diseases. Chinese hog producers are experiencing challenges such as falling hog prices, rising feed costs, and African swine fever, with some issuing profit warnings.
