Getting Real About the High Price of Cheap Food

By Bryan Walsh Friday, Aug. 21, 2009

“Somewhere in Iowa, a pig is being raised in a confined pen, packed in so tightly with other swine that their curly tails have been chopped off so they won\'t bite one another. To prevent him from getting sick in such close quarters, he is dosed with antibiotics. The waste produced by the pig and his thousands of pen mates on the factory farm where they live goes into manure lagoons that blanket neighboring communities with air pollution and a stomach-churning stench….”

History of the Pig
  • 9000+ years ago; Humans in caves/huts with pigs nearby
  • by 3,000-4,000 BC Persian*, Egyptian, Chinese & desert civilizations all ate pork & pigs were an important part of their culture
  • Pig herds spread West and North in Eurasia

* Muhammad lived 570-632 AD

History of the Pig
  • Jewish, Islamic and some Hindu sects stopped eating pork; reasons included
    • nomadic cultures not as suited to pigs as to cattle/sheep/camels
    • pigs ate waste products and were considered unhealthy
    • pork could contain parasites that made people sick

What was the industry image in Biblical times?

pigs were critical in history

  • Ancient Persia
  • Ancient Egypt
  • Ancient Greece
  • Roman Empire
  • Celtic nations
  • Colonizing nations (Spain, UK, Dutch, etc.)
  • Today
pigs in historical art
Pigs in Historical Art
  • Greek pig sculptures & drawing on a plate
  • circa 500 BC; Louvre, Paris
history of the pig3
History of the Pig
  • The Roman Empire improved pig breeding and spread pigs
  • Two types were developed:
    • Large, floppy ears, much lard
    • Smaller, erect ears, for meat

Iberian pigs from modern-day Spain

history of the pig4
History of the Pig

By the 1500s:

  • In the North, Celtic people bred large-bodied, well-muscled pigs
  • In Southern Europe, Iberians developed smaller-framed, lard-type pigs
  • All pigs of the day were dark colored
history of the pig5
History of the Pig

Sea-going explorers used live pigs (domestic and wild):

  • to eat along the way
  • to supply seedstock for new colonies
  • to hunt on a later visit

Explorers used pork in the form of:

  • salt pork
  • cured pork
usa phases of growth in pig s
USA Phases of Growth in Pig #s
  • Phase 1 -- The early settlers(colonial days)
  • Phase 2 -- 1776 to 1865(pigs move west)
  • Phase 3 -- 1865 to 1995(pigs with grain)
  • Phase 4 -- Now and futurea. Away from peopleb. Away from waterwaysc. Biosecurity concerns
world meat situation
World Meat Situation

Pork is the #1 meat eaten in the world

  • Pork 106 million metric tons
  • Beef 65 million metric tons
  • Poultry 95 million metric tons
meat production in 1969 2009 and projected for 2030
Meat Production in 1969, 2009 and Projected for 2030

** FAO estimate from 2003

2003 & 2009 FAO reports




Who is exporting pork?

FAO 2009:


usa import export of pork
USA Import-Export of Pork

USA exports are rising!


The USA Breeding Herd is shrinking in numbers

…But herd productivity is increasing and more pork is being produced with fewer sows


Corn prices were very high last year; they are lower now and we expect a large corn crop

… But price for pigs is still below break even by $20/pig or more

Break even


Hog farms have lost money, on average, for the last 40 months and will do so for at least another 8 months (until summer of 2010)

sows on large farms
Sows on large farms
  • In September, 2006, Smithfield bought PSF
  • Triumph Foods includes 5 or more producers


production technologies
Production Technologies
  • Cattle & Sheep are more often grazed
  • Pigs & Poultry are more intensified

Dramatic changes in global meat production could increase risk of diseases

Livestock producers should invest more in biosecurity and disease monitoring

17 September 2007, Rome - Global animal food production is undergoing a major transformation that could lead to a higher risk of disease transmission from animals to humans, FAO warned today.


production schedules
Production schedules
  • Based on a 20 or 21 week cycle
  • 20 groups of sows would be on a weekly schedule
  • Each week one group farrows another is weaned and another is bred
  • Shorter lactation length results in more litters per sow per year (up to a point)
what drives production
What drives production?
  • Lower the cost
  • Increase pigs per sow per year
    • Increase farrowing or conception rate
    • Increase litter size
  • Increase weight gain
  • Improve feed efficiency
  • Improve animal health
    • Morbidity
    • Mortality
benefits of pigs to the region
Benefits of Pigs to the Region
  • Kids and grand kids can stay here
  • Community prospers
  • Land values increase
  • Local grain and land have added value
  • Local multiplication of economic effect
  • Rural lifestyle can be protected
change in pig industry
Change in pig industry
  • Virtually no small, family commercial farms
  • Show pigs are a different industry in the USA and this is especially strong in Texas
  • Pork is a commodity or in a niche
  • Little opportunity to start a commercial pig farm and be successful in the USA
  • Great opportunities to work for corporations
  • International opportunities abound in Latin America, Eastern Europe and Asia
restructured usa pig industry
Restructured USA Pig Industry
  • About 50% of the pigs now come from very large farms, primarily corporations
  • The mid-sized farms are less competitive and therefore are exiting the industry
  • Society is concerned about:
    • The loss of the family farm
    • Pollution
    • Animal welfare
    • Food safety, etc.
  • The flip-side societal concern is: how will we feed 10 billion people?
