To obtain an accurate measurement of the U.S. swine industry, NASS surveyed over 8,500 operators across the nation during the first half of December. The data collected were received by electronic data recording, mail, telephone and through face-to-face interviews. All surveyed producers were asked to report their hog and pig inventories as of December 1, 2018.
