Other key findings in the report were:

  • Of the 72.9 million hogs and pigs, 66.7 million were market hogs, while 6.13 million were kept for breeding.
  • Between December 2022 and February 2023, 32.1 million pigs were weaned on U.S. farms, up slightly from the same time period one year earlier.
  • From December 2022 through February 2023, U.S. hog and pig producers weaned an average of 11.02 pigs per litter.
  • U.S. hog producers intend to have 2.93 million sows farrow between March and May 2023, and 2.97 million sows farrow between June and August 2023.
  • Iowa hog producers accounted for the largest inventory among the states, at 23.4 million head. Minnesota had the second largest inventory at 8.90 million head. North Carolina was third with 8.00 million head.

To obtain an accurate measurement of the U.S. swine industry, NASS surveyed roughly 4,500 operators across the nation during the first half of March. The data collected were received by electronic data recording, mail, telephone and through face-to-face interviews.

There will be a question-and-answer session during a live #StatChat on the @usda_nass Twitter account today at 4:00 p.m. EDT to answer your questions about the Quarterly Hogs and Pigs report. To ask a question, make sure you include the #StatChat to any questions you may have. The #statchat happens every quarter after the Quarterly Hogs and Pigs Report is released.

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Kwangwook Kim, Assistant Professor at Michigan State University, discusses the use of non-nutritive sweeteners in nursery pig diets. He explains how sucralose and neotame influence feed intake, gut health, metabolism, and the frequency of diarrhea compared to antibiotics. The conversation highlights mechanisms beyond palatability, including hormone signaling and nutrient transport. Listen now on all major platforms!

“Receptors responsible for sweet taste are present not only in the mouth but also along the intestinal tract.”

Meet the guest: Dr. Kwangwook Kim / kwangwook-kim is an Assistant Professor at Michigan State University, specializing in swine nutrition and feed additives under disease challenge models. He earned his M.S. and Ph.D. in Animal Sciences from the University of California, Davis, where he focused on intestinal health and metabolic responses in pigs. His research evaluates alternatives to antibiotics, targeting gut health and performance in nursery pigs.
