U.S. swine industry is changing fast

Who raises hogs?

How hogs are raised?

Where hogs are raised?

Vertical Integrationof the Swine Industry

• One company controls, through ownership or contract relationships, from the farm to the fork

Trends Changing the U.S. Swine Industry

1. Improved herd performance

- Producer efficiency -

2. Fewer & bigger hog farms

3. Specialization

4. Fewer & bigger packing plants

5. Geographic shift in production

6. Integration of production and packing

7. Contracting

8. Globalization

• Producer Efficiency– Pigs/litter

– Litters per breeding animal

– Market pigs per breeding animal

– Pork production per breeding animal

– Slaughter weights

Specialization

Allowed producers to become more efficient and lower costs of operation.

Modern Swine Production

Intensive management• Breeding programs - hybrids• Feeding programs• Environmentally controlled buildings• Disease control/sanitation is critical

– “all in, all out” production systems– “shower in, shower out”– Multiple-site systems

Where are pigs produced in the United States?

Geographic Shift

Geographic Shift in Hog Production

Sows are leaving the corn states

Hogs went to N.C. because N.C. developed a better system

Hogs are moving west to get away from rain and people

Sow Reproductive Information

Item Average

Age at puberty 4-7 mo

Estrous Cycle length 21 d

Duration of estrus 2-3 d

Occurrence of ovulation 2nd day of estrus

Gestation length 114 d

1st estrus postpartum 3-5 d post-weaning

Reproductive Management

• Estrus Detection - expose the sow/gilt to boar– vocalization, “flirt” with the ears– respond to pressure on the rump (won’t move)– greatly swollen vulva

Reproductive ManagementMating systems• Pen mating

– natural, but controlled matings based on estrus

• Artificial Insemination (AI) usage by large integrators (nearly 100%)– use “fresh” semen,

collected from boars on site– frozen semen yields

smaller litters than fresh

Farrowing• Process of the sow/gilt giving birth.

• Farrowing stalls (crates)– protect baby pigs from being “crushed”– provides for “dual heat”

• drip coolers for the sow• heat pads/lamps for

baby pigs (85-95o F)
