million head.  This was up  1 percent from Sept. 1, 2005 and up
2 percent from June 1, 2006. 

Breeding inventory, at 6.08 million head, was up 2 percent from

Revisions
               
All inventory and pig crop estimates for September 2005 through
June 2006 were reviewed using final pig crop, official slaughter,
death loss, and updated import and export data.  Based on the
findings of this review, a small adjustment of less than one-half
of one percent was made to the March 2006 inventory along with an
adjustment of slightly larger than one-half of one percent to the
June 2006 total inventory.
