Distribution and intensification of pig production in China 2007–2017

Abstract

Driven by population growth and rising incomes, the demand for animal source foods in low and middle-income countries is increasing rapidly. Pork is one of the most commonly consumed animal-based food, with the highest demand being in China due to its largest population and changing dietary habits linked to increasing wealth. Here, we show the changes in pig production systems in terms of farms capacity, productivity and production at the national and provincial levels by analyzing several censuses of China. In addition, we used a downscaling methodology to provide a recent and highly detailed map of the distribution of pigs in China. Between 2007 and 2017, pork production in China increased by 26.6\%, up to 55 million tons and the number of large-scale farms with a yearly production of over 10 000 heads increased by 145\%. Much of the production has changed from extensive backyard subsistence farming to intensive corporate farming. Moreover, the pig distribution has shifted from watercourse-intense southeast to northeast and southwest of China due to environmental policy in 2015. These policy-driven transitions primarily aimed to increase pig production efficiency and reduce environmental impacts and resulted in a profound transformation of geographic production patterns.

Assessing and improving on-farm biosecurity knowledge and practices among swine producers and veterinarians through online surveys and an educational website in Illinois, United States

“…However, a good proportion of our users were Mandarin and Spanish speakers. These findings were expected as China is a leading pork producer worldwide (59), which recently experienced a devastating ASF outbreak (60) that might increase pork producers' awareness of infectious swine diseases and eagerness to learn more about effective disease prevention methods. The high proportion of Spanish-speaking visitors on the website can be explained by the data suggesting that over three-quarters of agricultural workers worldwide are Spanish speakers (61, 62).…”

Isolation, Identification, Genomic Diversity, and Antimicrobial Resistance Analysis of Streptococcus suis in Hubei Province of China from 2021 to 2023

“…Hubei, a prominent pig production and transportation center in China [36], recorded a total annual pig production of 42.86 million in 2022. However, little well-directed data regarding the genomics and AMR of S. suis have been reported in Hubei Province.…”

Can States Become Wealthier While Keeping Livestock Intensification Low? Evidence From India

“…This is important since the impacts of livestock for society, the environment, public health, and animal welfare depend not only on the densities of livestock, but on the modes of production used to rear them. Some studies have examined intensification across a specific region or country, but all of these have looked at spatial predictor variables such as availability of cheap feed or vegetation, topography, access to cheap markets, and climate, rather than wealth (Cheng et al, 2023;Gerber et al, 2005;Van Boeckel et al, 2012;Zhao et al, 2022).…”
