United States inventory of all hogs and pigs on December 1, 2013 was 65.9 million head. This was down 1 percent from December 1, 2012, and down 2 percent from September 1, 2013.
Breeding inventory, at 5.76 million head, was down 1 percent from last year, and down 1 percent from the previous quarter.
Market hog inventory, at 60.2 million head, was down 1 percent from last year, and down 2 percent from last quarter.
The September-November 2013 pig crop, at 29.3 million head, was down slightly from 2012. Sows farrowing during this period totaled 2.88 million head, down slightly from 2012. The sows farrowed during this quarter represented 50 percent of the breeding herd. The average pigs saved per litter was a record high 10.16 for the September-November period, compared to 10.15 last year. Pigs saved per litter by size of operation ranged from 8.00 for operations with 1-99 hogs and pigs to 10.20 for operations with more than 5,000 hogs and pigs.
Although producers intend to farrow more sows in the first half of 2014, the impacts of the Porcine Epidemic Diarrhea virus (PEDv) will likely slow growth in pigs per litter and keep supplies of market hogs relatively tight during 2014.
