U.S. hog producers intend to have 2.89 million sows farrow during the June-August 2010 quarter,
down 2 percent from the actual farrowings during the same period in 2009 and down 6 percent from
2008. Intended farrowings for September-November 2010, at 2.90 million sows, are down 1 percent
from 2009 and down 4 percent from 2008.
The total number of hogs under contract owned by operations with over 5,000 head, but raised by
contractees, accounted for 44 percent of the total U.S. hog inventory, down from 46 percent last year.
Revisions
All inventory and pig crop estimates for June 2009 through March 2010 were reviewed using slaughter,
death loss and current import and export data. Based on this review, adjustments of less than one
percent were made to the December 2009 total inventory and March 2010 total inventory. An
adjustment of two percent was made to the September-November 2009 pig crop.
This report was approved on June 25, 2010.

Quarterly Hogs and Pigs Agricultural Statistics Board
June 2010 18 NASS, USDA
Reliability of June 1 Hogs and Pigs Estimates
Survey Procedures: A random sample of roughly 8,800 U.S. 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 producers were sampled more heavily than small operations.
During the first half of June 2010, data were collected from about 7,200 operations, 82 percent of the
total sample. The data collected were received by electronic data reporting (EDR), mail, telephone, and
face-to-face personal interviews. Regardless of when operations responded, they were asked to report
inventories as of June 1, 2010.
Estimation Procedures: Hogs and pigs estimates were prepared by the Agricultural Statistics Board
after reviewing recommendations and analysis submitted by each 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 for all quarters of the current and previous year are reviewed. 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 affects 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
1.6 percent. This means that chances are 2 out of 3 that the final estimate will not be above or below the
current estimate of 64.4 million head by more than 1.6 percent. Chances are 9 out of 10 that the
difference will not exceed 2.8 percent.
