RESEARCH: About 17% of US sows kept in group housing

Results of a survey issued at the World Pork Expo show that to date, about 17.3% of the US sows spends some time in group housing. The remaining 83.7% are kept in gestation stalls.

The survey, conducted by University of Missouri extension economist Ron Plain, researched pork operations with 1,000 or more sows. He received responses from 70 operations, which combined own about 3.6 million of the nation’s 5.7 million sows.

The findings confirm NPPC’s concerns about recent pronouncements by food companies that they will use only pork from operations that are gestation-stall free.

The Plain survey found that 20.2% of sows on operations of 1,000-9,999 sows, 18.9% on operations of 10,000-99,999 and 16.4% on operations of more than 100,000 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% 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 would have 20.7%. 

NPPC – challenging
The National Pork Producers Council (NPPC), critical about the development to phase out sow stalls, noted 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.

“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,” R.C. Hunt, NPPC president, said. “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.”

“Today’s survey shows that these food companies obviously haven’t thought through the complexities, logistics or implications of their requests,” said Hunt. “Simply making an announcement without understanding the entire supply chain’s ability to meet these requests or the challenges involved is utterly befuddling. We feel it is important to have this first-hand information available to our customers.”
