A survey released at the
2012 World Pork Expo found
that a majority of the U.S. sow herd spends some time in individual housing or
gestation stalls. Recently, several large fast-food companies announced they
will only use pork from pig operations that are
gestation-stall free.
The survey, conducted by University of Missouri extension economist Ron
Plain, found that currently only 17.3 percent of sows spend a portion of
gestation in open pens. Plain surveyed pork operations with 1,000 or more sows
and received responses from 70 operations, which combined about 3.6 million of
the nation’s 5.7 million sows.
“Today’s survey shows that these food companies obviously haven’t thought
through the complexities, logistics or implications of their requests,” said
National Pork Producers Council President R.C. Hunt, a pork
producer from Wilson, N.C. “Simply making an announcement without understanding
the entire supply chain’s ability to meet these requests or the challenges
involved are utterly befuddling. We feel it is important to have this first-hand
information available to our customers.”

The Plain survey found that 20.2 percent of sows on operations of 1,000-9,999
sows, 18.9 percent on operations of 10,000-99,999 sows and 16.4 percent on
operations of more than 100,000 sows are in open pens for some portion of
gestation. When asked about plans to put more sows in open pens, the largest
operations indicated that 23.8 percent of their sows would be in them in two
years, operations of 10,000-99,999 sows would have 21.3 of their pigs in such
pens and operations of 1,000-9,999 sows would have 20.7 percent.
“Given that few sows always are in open housing and that producers may use
both individual and group housing, it would be extremely difficult and costly
for the pork supply chain to sort, segregate and trace product to meet the
requirements of these food companies,” said Hunt. “Regardless, this issue is
about giving animals the best care possible, and hog farmers like me know
through years of experience that individual housing provides that best
care.”
But it is important to note, according to the NPPC, that an operation may use
both individual and open pen, or group, housing and that sows on some operations
may spend time in both systems.
