Quarterly Hogs and Pigs

Agricultural Statistics Board Briefing

Travis Averill, Chief

Livestock Branch

December 23, 2021
Special Note

Each December, NASS procedures allow for revisions to 

the previous 8 quarters of estimates for hogs and pigs. 

Since March 20, 2020, NASS has suspended in person 

data collection due to the pandemic for health and safety 

reasons. In addition, the pandemic has impacted 

production practices and slaughter plant operations 

during this unprecedented time in various magnitudes. 

The December 2019 quarterly revisions are available only 

in Quick Stats, whereas all other quarterly revisions are 

provided in this report and Quick Stats. Please contact 

the Livestock Branch at (202) 692-0069 or email at 

hq_sd_lb@usda.gov with any questions or concerns.
