Quarterly Hogs and Pigs ISSN: 1949-1921 Released September 28, 2017, by the National Agricultural Statistics Service (NASS), Agricultural Statistics Board, United States Department of Agriculture (USDA). United States Hog Inventory Up 2 Percent United States inventory of all hogs and pigs on September 1, 2017 was 73.5 million head. This was up 2 percent from September 1, 2016, and up 3 percent from June 1, 2017. Breeding inventory, at 6.09 million head, was up 1 percent from last year, and up slightly from the previous quarter. Market hog inventory, at 67.5 million head, was up 3 percent from last year, and up 3 percent from last quarter. The June-August 2017 pig crop, at 33.0 million head, was up 2 percent from 2016. Sows farrowing during this period totaled 3.10 million head, up 2 percent from 2016. The sows farrowed during this quarter represented 51 percent of the breeding herd. The average pigs saved per litter was a record high of 10.65 for the June-August period, compared to 10.58 last year. Pigs saved per litter by size of operation ranged from 7.80 for operations with 1- 99 hogs and pigs to 10.70 for operations with more than 5,000 hogs and pigs. United States hog producers intend to have 3.07 million sows farrow during the September-November 2017 quarter, up 1 percent from the actual farrowings during the same period in 2016, and up 5 percent from 2015. Intended farrowings for December-February 2018, at 3.02 million sows, are up 1 percent from 2017, and up 3 percent from 2016. The total number of hogs under contract owned by operations with over 5,000 head, but raised by contractees, accounted for 47 percent of the total United States hog inventory, unchanged from the previous year. Revisions All inventory and pig crop estimates for September 2016 through June 2017 were reviewed using final pig crop, official slaughter, death loss, and updated import and export data. The net revision made to the September 2016 all hogs and pigs inventory was 1.3 percent. The net revision made to the March 2017 all hogs and pigs inventory was 0.4 percent. A revision of 0.8 percent was made to the December-February 2017 pig crop. A revision of 0.3 percent was made to the June 2017 all hogs and pigs inventory.

Statistical Methodology Survey Procedures: A random sample of roughly 7,500 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 2017, data were collected from about 5,500 operations, 72 percent of the total sample. 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, 2017. Estimating 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 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 73.5 million head by more than 1.4 percent. Chances are 9 out of 10 that the difference will not exceed 2.4 percent.
