United States Hog Inventory Up 3 Percent United States inventory of all hogs and pigs on June 1, 2017 was 71.7 million head. This was up 3 percent from June 1, 2016, and up 1 percent from March 1, 2017. This is the highest June 1 inventory of all hogs and pigs since estimates began in 1964. Breeding inventory, at 6.07 million head, was up 2 percent from last year, and up slightly from the previous quarter. Market hog inventory, at 65.6 million head, was up 4 percent from last year, and up 1 percent from last quarter. This is the highest June 1 market hog inventory since estimates began in 1964. The March-May 2017 pig crop, at 32.3 million head, was up 4 percent from 2016. This is the second largest March-May pig crop since since estimates began in 1970. Sows farrowed during this period totaled 3.06 million head, up 3 percent from 2016. The sows farrowed during this quarter represented 50 percent of the breeding herd. The average pigs saved per litter was a record high 10.55 for the March-May period, compared to 10.48 last year. Pigs saved per litter by size of operation ranged from 7.70 for operations with 1-99 hogs and pigs to 10.60 for operations with more than 5,000 hogs and pigs. United States hog producers intend to have 3.06 million sows farrow during the June-August 2017 quarter, up slightly from the actual farrowings during the same period in 2016, and up 2 percent from 2015. Intended farrowings for September-November 2017, at 3.06 million sows, are up slightly from 2016, and up 4 percent from 2015. The total number of hogs under contract owned by operations with over 5,000 head, but raised by contractees, accounted for 48 percent of the total United States hog inventory, up from 47 percent the previous year.

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 June 2017, data were collected from about 5,400 operations, 71 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 June 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 71.7 million head by more than 1.4 percent. Chances are 9 out of 10 that the difference will not exceed 2.5 percent.
