Minor Expansion in US Hog Herd Confirmed

Mar 30, 2023

As expected, the USDA’s latest quarterly hogs and pigs report confirmed some minor expansion in the US hog herd.

Released Thursday, the report pegged the total US inventory of all hogs and pigs as of March at 72.86 million head, up about 0.2% from 72.68 million on the same date last year. Pre-report expectations were for a slightly more aggressive year-over-year increase of 0.3%.

The March 1 breeding inventory, at 6.13 million head was up roughly 0.5% on the year, compared to trade ideas of 0.6%. The number of market hogs came in at 66.73 million, an increase of about 0.2% from 66.59 million a year ago, but still also slightly below expectations.

The December 2022-February 2023 pig crop, at 32.1 million head, was up slightly from last year. Sows farrowing during this period totaled 2.91 million head, down slightly from previous year. The average pigs saved per litter was 11.02 for the December 2022-February 2023 period, compared to 10.95 last year.

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
