All inventory and pig crop estimates for September 2008 through June 2009 were reviewed using slaughter, death loss and current import and export data. Based on this review, adjustments of less than one percent were made to the March 2009 and June 2009 total inventory.  An adjustment of less than two percent was made to the December 2008-February 2009 pig crop.
