United States Hog Inventory Down 1 Percent

80
United States inventory of all hogs and pigs on September 1, 2022 was 
73.8 million head. This was down 1 percent from
September 1, 2021, but up 2 percent from June 1, 2022.   

Breeding inventory, at 6.15 million head, was down 1 percent from last year, 
and down slightly from the previous quarter.

Market hog inventory, at 67.6 million head, was down 1 percent from last 
year, but up 2 percent from last quarter. 

The June-August 2022 pig crop, at 33.6 million head, was down 1 percent from 
2021. Sows farrowing during this period totaled 3.02 million head, down 
1 percent from 2021. The sows farrowed during this quarter represented 49 
percent of the breeding herd. The average pigs saved per litter was 11.13 for 
the June-August period, unchanged from last year. 

United States hog producers intend to have 2.97 million sows farrow during 
the September-November 2022 quarter, down 2 percent from the actual 
farrowings during the same period one year earlier, and down 6 percent from 
the same period two years earlier. Intended farrowings for December 2022-
February 2023, at 2.90 million sows, are down 1 percent from the same period 
one year earlier, and down 1 percent from the same period two years earlier. 

The total number of hogs under contract owned by operations with over 5,000 
head, but raised by contractees, accounted for 50 percent of the total United 
States hog inventory, up 1 percent from the previous year. 

Revisions

All inventory and pig crop estimates for September 2021 through June 2022 
were reviewed using final pig crop, official slaughter, death loss, and 
updated import and export data. The revision made to the March 2022-May 2022 
pig crop was 0.1 percent. A net revision of 0.7 percent was made to the March 
2022 all hogs and pigs inventory. The net revision made to the December 2021-
February 2022 pig crop was 0.6 percent.

Statistical Methodology

Survey Procedures: A random sample of roughly 4,700 United States producers 
was surveyed to provide data for these estimates. Survey procedures ensured 
that all hog and pig producers, regardless of size, had a chance to be 
included in the survey. Large operations were sampled more heavily than small 
operations. During the first half of September 2022, data were collected from 
about 3,000 operations. The data collected were received by electronic data 
reporting, mail, telephone, and face-to-face personal interviews. Regardless 
of when operations responded, they were asked to report inventories as of 
September 1, 2022.

Estimating Procedures: Hogs and pigs estimates were prepared by the 
Agricultural Statistics Board after reviewing recommendations and analysis 
submitted by each regional field office. National and State survey data were 
reviewed for reasonableness with each other and with estimates from past 
years using a balance sheet. The balance sheet begins with the previous 
inventory estimate, adds the estimates of births and imports, and subtracts 
the estimates of slaughter, exports, and deaths. This indicated ending 
inventory level is compared to the Agricultural Statistics Board estimate for 
reasonableness.

Revision Policy: Revisions to previous estimates are made to improve quarter 
to quarter relationships. Estimates for the previous four quarters are 
subject to revision when current estimates are made. In December, estimates 
are reviewed from all quarters of the current year, all quarters of the 
previous year, and December two years prior. The reviews are primarily based 
on hog check-off receipts and slaughter. Estimates will also be reviewed 
after data from the Department of Agriculture five-year Census of Agriculture 
are available. No revisions will be made after that date.

Reliability: Since all operations raising hogs are not included in the 
sample, survey estimates are subject to sampling variability. Survey results 
are also subject to non-sampling errors such as omissions, duplication, and 
mistakes in reporting, recording, and processing the data. The effects of 
these errors cannot be measured directly. They are minimized through rigid 
quality controls in the data collection process and through a careful review 
of all reported data for consistency and reasonableness.

To assist users in evaluating the reliability of the estimates in this 
report, the "Root Mean Square Error" is shown for selected items in the 
following table. The "Root Mean Square Error" is a statistical measure based 
on past performance and is computed using the difference between first and 
final estimates. The "Root Mean Square Error" for hog inventory estimates 
over the past 20 quarters is 1.4 percent. This means that chances are 2 out 
of 3 that the final estimate will not be above or below the current estimate 
of 73.8 million head by more than 1.4 percent. Chances are 9 out of 10 that 
the difference will not exceed 2.4 percent.
