Pork industry estimates 17 percent of sows in open pens

DES MOINES, Iowa -- Estimates regarding how many U.S. sows are housed in open pen gestation systems have varied widely. The Humane Society of the United States (HSUS) and some food companies tend to point to 30 percent of sows as the current industry level.

However, the National Pork Producers Council (NPPC) joined forces with University of Missouri agricultural economist Ron Plain to get a more accurate industry assessment. The team conducted an email survey touching on operations with 1,000 or more sows. The survey just wrapped up on Tuesday of this week and Plain reported the results at World Pork Expo today in Des Moines.

Plain referred to the survey as a "fast attempt" to determine the production level and the process took less than a month. "You can't survey all U.S. hog farms in that time," he said. So he opted for a representative sample. In the end, the survey involved 70 firms, and 3.6 million sows and breeding gilts. With an estimated 5.7 million sows in the U.S. breeding herd, that means the survey covered 62.6 percent of the herd. The survey respondents involved personnel who either owned or managed the sows. 

"We asked what percentage of females are housed in open-pen gestation, which we defined as females that, once they were confirmed as pregnant, were housed in pens where they could not touch the sides," Plain reported. The overall average came up at 17 percent.

For a more precise breakdown, Plain indicted that for operations with 1,000 to 9,999 sows, 20.2 percent were in open-pen gestation at some point; for units with 10,000 to 99.999, it was 18.9 percent; and for herds with more than 100,000 sows, the rate was 16.4 percent.

The 17 percent average is slightly higher than the industry anticipated, which would have been in the 10 percent area.

The survey also asked what percentage might be housed in pens two years from now and the responses averaged 23 percent of the sows would be in pens, Plain added. Again, the levels broke down as 20.7 percent for systems with 1,000 to 9,999 sows; 21.3 percent for herds with 10,000 to 99,999; and 23.8 percent for the largest operations. 

NPPC and Plain both emphasized that a lot of operations run some combination of pen and stall housing and the survey numbers do not mean that the sow was always housed in pen gestation, but rather that the animal spent some amount of time in a pen. Neither does the estimate mean that 17 percent of U.S. production comes from open-pen gestation.

"This is a very complex issue," said Dallas Hockman, NPPC's vice president of industry relations, "and the most dramatic one in my 30 years in the industry." He noted that pork producers conducted the survey in order to "bring forth the facts," regarding the availability and potential supply of pork from systems not tied to getstation-sow stalls.

"Our customers expressed the need for information on the supply of pork and we wanted to reach out to producers to provide factual information," Hockman noted.

He emphasized that pork producers "do care" about about how their hogs are raised and that they deserve to be part of the dialogue involving food companies' long-term plans. "It's a truth in labeling issue and whether or not product can be segregated and met the demand," Hockman added. "Consumers deserve to get the product promised, and we want to deal in factual information."

He added: "The key take-away is that we stand ready and willing to talk with our customers about what they need; it's not a matter of drawing a line in the sand."

But he pointed out that there will be many costs along the way, not just for producers but for packer/processors, transportation issues and other requirements to maintaoin a segregated product. "It's a complex issue," Hockman noted again.

Over 30 years of records, Will never go back to open pens, Even if it's against the law. HSUS is not the experts. You can not tell me open pens with a 27% cull rate is better than 12% in crates. Crates - born alive 9.8 pigs, Open pens - 8.9 born alive, One thing is for sure it would raise prices.

That seems nuts. We gotta evolve. Adapt or die, right? People want more room for pigs, then more room we should give them. There are humane ways to do group housing.

Dr. Temple Grandin seems like a pretty good expert on the issue, and she says the pork industry should phase out gestation crates for pigs and move to group housing systems.

i think its crazy to NOT make the switch to group housing. our stalls are gonna depreciate soon enough, and i for one want to give my pigs more room...especially now that i see all the big buyers i'll have!

I want some industry leadership that's going in the right direction! We're constantly changing the way we do business, and this issue should be no different. A decade ago, sales were lagging, and we changed our practices to recover. Group housing is the newest push. So what? Let's just do it.

While I don't raise pigs, my family did when I was growing up. I saw what happens when sows have plenty of room and are in groups. It wasn't pretty even ours was a small number, probaby always fewer than 20 sows. Too many piglets killed one way or another by sows, pigs maimed by one another, ets. We asked animal science departments to help find better ways. They did: farrowing crates resulted. My question: what are you going to do to protect the animals from their natural instincts in group housing? Much of the criticism of stalls and support from pens seems to come (on this site) from people who believe they will reap the rewards of people willing to pay higher prices for changing systems. So, wouldn't the honest thing be to simply advertise your kinder, gentler system, and stop bashing those who are using the best of current science to raise their pigs? Why not sell your product on IT'S merit, NOT by bashing the science based crate system, if you believe in going back to past 'free range' systems? The bonus would be that a determined animal RIGHTS groups would not be gaining leverage against all other food animal producers by gaining your support......because that is where all this really originates, IMO.
