As of September 1, 2025, the number of hogs and pigs on farms in the United States was 74.5 million, according to a new report from the U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS). This figure represents a 1% decrease compared to September 2024 but a 1% increase from June 1, 2025.
The report found that out of the total inventory, 68.5 million were market hogs and 5.93 million were kept for breeding purposes. Between June and August of this year, U.S. farms weaned 34.1 million pigs, which is a decline of 3% from the same period last year. From June through September, producers weaned an average of 11.82 pigs per litter.
Looking ahead, U.S. hog producers plan to have approximately 2.86 million sows farrow between September and November this year and about 2.82 million sows farrow between December and February next year.
Iowa continues to lead among states with the largest hog inventory at 25.1 million head, followed by Minnesota with 8.75 million head and North Carolina with 7.80 million head.
To compile these figures, NASS surveyed nearly 4,500 operators nationwide during early September using online responses, mail-in surveys, telephone interviews, and in-person visits.
