title: Modern pig farming in the People's Republic of China: growth and veterinary challenges.
abstract: Cyclical oversupply and non-profitability situations have led to pig industry consolidations in the People's Republic of China, with many smaller farmers leaving the industry. In 2007, pork supply worsened due to outbreaks of 'high fever blue-ear disease', a complex disease issue that includes highly virulent porcine reproductive and respiratory syndrome, porcine circovirus and classical swine fever. Best estimates suggest that 50 million pigs were affected. More recent natural disasters (earthquakes/freezing winters) have also limited pig production in some areas. Overall expansion of the Chinese breeding herd is now continuing at a good pace and is likely to be sufficient to supply the predicted 7% annual increase in demand for pork. High prices of feed ingredients (cereals and soybean) continue to create cost-of-production issues. Authorities have instigated many helpful measures over the past decade, including insurance for farm breeder stock, direct subsidies for farm expansions and breeding programmes, free supplies of some vaccines, and taxation exemptions. Specific challenges remaining include: the high levels of spread, persistence and on-farm impact of key virus infections on single-site farm systems; the variable titre and potency of some local vaccines; the low level of technical capacity in laboratories and the lack of training and expertise among farm staff; and the lack of a distinctive representative voice for pig farmers.
