Today’s U.S. Pork Industry
- There are 85,760 pork operations today compared with 3 million in
1950
- 80% of the hogs are grown on farms which produce 5000 or more hogs
per year
- Feed represents 65-75% of the total cost of production
- Smithfield Foods
- Worlds largest vertically integrated hog operation
- 700,000 sows
- 12 million market hogs annually
- controls about 15% of hogs in the US
Why Does This Matter?
- These influences have driven the industry to essentially all-confinement,
high-intensity rearing and this dramatically influences how hogs are
fed and managed.
- What does Smithfield do with the manure from 12 million hogs?
- What does Smithfield do with the unwanted fat on these hogs?
- How does ration formulation relate to these management issues?

Vitamin Ca |
| aAlthough vitamin C can be synthesized by
the pig, research evidence suggests that the early-weaned pig may
require a supplemental source in the diet for a short period postweaning. |
Production Phase
- Starter Pigs (10-50 lbs)
- Grower Pigs (50-140 lbs)
- Finisher Pigs 140-250 lbs)
