U.S. Hog Inventory Up 1 PercentU.S. inventory of all hogs and pigs on March 1, 2007 was 61.1 million head. This was up 1 percent from March 1, 2006, but down 2 percent from December 1, 2006. Breeding inventory, at 6.08 million head, was up 1 percent from last year, but down slightly from the previous quarter. Market hog inventory, at 55.0 million head, was up 1 percent from last year, but down 2 percent from last quarter. The December 2006-February 2007 pig crop, at 26.1 million head, was up 2 percent from 2006 and up 3 percent from 2005. Sows farrowing during this period totaled 2.87 million head, up 1 percent from both 2006 and 2005. The sows farrowed during this quarter represented 47 percent of the breeding herd. The average pigs saved per litter was 9.08 for the December 2006-February 2007 period, compared to 9.03 last year. Pigs saved per litter by size of operation ranged from 7.60 for operations with 1-99 hogs and pigs to 9.20 for operations with more than 5,000 hogs and pigs. U.S. hog producers intend to have 2.91 million sows farrow during the March-May 2007 quarter, down slightly from the actual farrowings, but up 1 percent from 2005. Intended farrowings for June-August 2007, at 2.92 million sows, are virtually unchanged from both 2006 and 2005. The total number of hogs under contract, owned by operations with over 5,000 head, but raised by contractees, accounted for 39 percent of the total U.S. hog inventory, unchanged from last year. Revisions All inventory and pig crop estimates for March 2006 through December 2006 were reviewed using final pig crop, official slaughter, death loss, and updated import and export data. Based on the findings of this review, small adjustments of less than one-half of one percent were made to the March 1, 2006 total inventory, September 1, 2006 total inventory, March-May 2006 pig crop and the September-November pig crop. An adjustment slightly larger than one-half of one percent was made to the June-August 2006 pig crop.

Reliability of March 1 Hogs and Pigs Estimates
Survey Procedures: A random sample of roughly 9,300 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 March, data were collected from about 7,350 operations, 79 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 March 1.
Estimation Procedures: These 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 0.9 percent. This means that chances are 2 out of 3 that the final estimate will not be above or below the current estimate of 61.1 million head by more than 0.9 percent. Chances are 9 out of 10 that the difference will not exceed 1.5 percent.
