According to the USDA's Quarterly Hogs and Pigs report, issued on Sept. 28, United States inventory of all hogs and pigs on Sept. 1, 2012 was 67.5 million head. This was up slightly from Sept. 1, 2011, and up 3 percent from June 1, 2012.

Breeding inventory, at 5.79 million head, was down slightly from last year, and down 1 percent from the previous quarter. Market hog inventory, at 61.7 million head, was up slightly from last year, and up 3 percent from last quarter.

The June-August 2012 pig crop, at 29.3 million head, was down slightly from 2011. Sows farrowing during this period totaled 2.89 million head, down 1 percent from 2011. The sows farrowed during this quarter represented 49 percent of the breeding herd.

The average pigs saved per litter was a record high 10.13 for the June-August period, compared to 10.03 last year. Pigs saved per litter by size of operation ranged from 7.60 for operations with 1-99 hogs and pigs to 10.20 for operations with more than 5,000 hogs and pigs.

Intended farrowings for December-February 2013, at 2.82 million sows, are down 1 percent from 2012 and down 1 percent from 2011.
