Sows farrowing during this period totaled 2.86 million head, down 1 percent from 2010 and down 5 percent  from 2009. The sows farrowed during this quarter represented 49 percent of the breeding herd. The average pigs saved per litter was a record high 9.80 for the Dec. 2010-Feb. 2011 period, compared to 9.61 last year. Pigs saved per litter by size of operation ranged from 7.50 for operations with 1-99 hogs and pigs to 9.90 for operations with more than 5,000 hogs and pigs.

All inventory and pig crop estimates for June 2009 through Dec. 2010 were reviewed using final pig crop, official slaughter, death loss, and updated import and export data. Based on the findings of this review, an adjustment of slightly more than one percent was made to the Sept. 2010 total inventory.  An adjustment of less than one half of one percent was made to the Dec. 2010 total inventory. An adjustment of more than one percent was made to the June-Aug. 2010 pig crop.
