The government’s tough new pollution standards ban livestock production near water sources or high populated areas
(Reuters) — China’s pig herd shrank last month at the fastest pace in almost two years, the Ministry of Agriculture said, the latest sign sweeping government steps to curb pollution have accelerated cuts in one of the nation’s critical farm sectors.
The hog herd in the world’s top pork consumer fell by 6.1 percent from a year earlier, the biggest percentage drop since January last year.
The sow herd was down five percent, the largest drop since March 2016. The government does not disclose the size of the herds.

Both sow and hog herds have registered a year-on-year drop each month since at least the start of 2016, but the pace of the decline has accelerated since July, as efforts to comply with new regulations gather pace.
In July, the pig herd fell by 4.8 percent and the sow herd by 4.2 percent, government records show.
