Of the 74.5 million hogs and pigs, 68.5 million were market hogs, while 5.93 million were kept for breeding.

Between June and August 2025, 34.1 million pigs were weaned on US farms, down 3% from the same time period one year earlier.

From June through September 2025, US hog and pig producers weaned an average of 11.82 pigs per litter.

US hog producers intend to have 2.86 million sows farrow between September and November 2025, and 2.82 million sows farrow between December 2025 and February 2026.

Iowa hog producers accounted for the largest inventory among the states, at 25.1 million head. Minnesota had the second largest inventory at 8.75 million head. North Carolina was third with 7.80 million head.

To obtain an accurate measurement of the US swine industry, NASS surveyed 4,479 operators across the nation during the first half of September 2025. The data collected were received online through NASS’s Respondent Portal, by mail, telephone and through face-to-face interviews.
