Report Tables

Special Note

Monthly farrowing and pig crop estimates are preliminary and may be revised in the Quarterly Hogs and Pigs Reports. Various factors can require revisions, such as sample variability, difference in reporting time-frame (monthly vs. quarterly), and pre-weaning and post-weaning death loss. Please refer to the Revision Policy on Page 3 of this report for more information.

Survey Procedures: A random sample of 2,800 U.S. producers from contractors to independent producers were used to provide data for these estimates. Survey procedures ensured that all breeding and farrowing operations, regardless of size, had a chance to be included in the survey. Large producers were sampled more heavily than small operations. Data were collected during the first-half of the month by mail, telephone, and face-to-face personal interviews. Operations were asked to provide information on sow and gilt inventories as of the first of the month, sows and gilts bred during the previous month, sows and gilts farrowed during the previous month, and the pig crop from these litters.

Revision Policy: Revisions to previous monthly estimates are made during the quarterly report. These revisions are to improve month to month, and quarter to quarter relationships. In December, estimates for all months and 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 with sow and gilt inventory 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.
