Quarterly USDA Report Shows Minor Herd Changes

U.S. hog inventory slightly declines

The U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS) announced that as of September 1, 2025, there were 74.5 million hogs and pigs on American farms. This marks a 1% decrease from September 2024 but a 1% increase compared to June 1, 2025. 

Of the total inventory, 68.5 million were market hogs raised for meat production, while 5.93 million were kept for breeding purposes. Between June and August 2025, farmers weaned 34.1 million pigs, which is 3% fewer than during the same period last year. From June through September, producers averaged 11.82 pigs per litter. 

Looking ahead, U.S. hog producers plan to have 2.86 million sows farrow, or give birth, between September and November 2025. Another 2.82 million sows are expected to farrow between December 2025 and February 2026, ensuring steady future production. 

Iowa continues to lead the nation in hog numbers with 25.1 million head. Minnesota follows with 8.75 million, and North Carolina ranks third with 7.80 million head. 

To gather these figures, NASS surveyed 4,479 hog and pig operators across the country in early September. Data collection was completed through online submissions, mail, telephone interviews, and face-to-face visits, ensuring accurate and reliable reporting. 

The full Quarterly Hogs and Pigs report, along with other agricultural updates, is available on the NASS website. This regular report provides valuable insight into the size and health of the U.S. swine industry, helping farmers, businesses, and policy makers make informed decisions about production and marketing.
