U.S. Hog Inventory Up 6 Percent U.S. inventory of all hogs and pigs on June 1, 1998, was 61.6 million head. This was 6 percent above June 1997, and 3 percent above March 1, 1998. Breeding inventory, at 7.02 million head, was up 1 percent from June 1, 1997 and up slightly from March 1, 1998. Market hog inventory, at 54.6 million head, was 6 percent above last year, and 3 percent above last quarter. The March-May 1998 U.S. pig crop, at 26.7 million head, was 5 percent more than 1997 and 7 percent more than 1996. Sows farrowing during this period totaled 3.06 million head, 4 percent above last year. The sows farrowed during this quarter represented 44 percent of the breeding herd. The average pigs per litter continues to increase, with an average of 8.74 pigs saved per litter for the March-May period. Last year the litter rate averaged 8.65 pigs. Pigs saved per litter by size of operation ranged from 7.30 for operations with 1-99 hogs to 8.90 for operations with more than 5,000 hogs and pigs. U.S. hog producers intend to have 3.03 million sows farrow during the June-August 1998 quarter, 3 percent above the actual farrowings during the same period in 1997 and 10 percent above 1996. Intended farrowings for September-November 1998, at 3.04 million sows, are 4 percent above the same period last year and 12 percent above 1996. The total number of hogs under contract, owned by operations with over 5,000 head, but raised by contractees, accounted for 27 percent of the total U.S. hog inventory. Revisions All inventory and pig crop estimates for 1997 and March 1998 were reviewed using final pig crop, official slaughter, import, and export data in U.S. level balance sheets. Based on the findings of this review, small adjustments to the previous quarters estimates were made. This report was approved on June 26, 1998. Acting Secretary of Agriculture Richard E.

Reliability of June 1 Hogs and Pigs Estimates Survey Procedures: A random sample of 13,835 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. Data were collected from about 11,642 operations, 84.1 percent of the total sample, during the first-half of June by mail, telephone, and face-to-face personal interviews. Regardless of when operations responded, they were asked to report inventories as of June 1. Estimation Procedures: These hogs and pigs estimates were prepared by the Agricultural Statistics Board after reviewing recommendations and analysis submitted by each State 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 to it estimates of births and imports, and subtracts 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 June, 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 1.7 percent. This means that chances are 2 out of 3 that the final estimate will not be above or below the current estimate of 61.6 million head by more than 1.7 percent, or about 1,047,000 head. Chances are 9 out of 10 that the difference will not exceed 2.9 percent, or about 1,786,000 head (the 90 percent confidence level).
