What is the timeline of a pig’s life?
breeding –> gestation (3mo, 3 wks, 3 days=114 days) –> farrowing (weaning=10-15 lbs) – nursery (>12-40lbs) –>
grower (40-120 lbs) –> finisher (120 to 250 lbs)
5 Primary Types of Swine Operations
- Purebred or Seedstock operations.
- Farrow to wean.
- Finishing.
- Farrow-to-finish operation.
- Integrated corporate production.
Purebred or Seedstock Operations
Similar to farrow-to-finish except the end product is primarily breeding boars and gilts or show pigs, which may be purebred or controlled crossbreeds
<1% of total hogs raised in the US
Farrow-to-Wean Operations
Breeding herd (sows and boars) produces:
(1) Early-weaned pigs at 10–15 lbs
or
(2) Feeder pigs at 35–50 lbs
Finishing Operation
Feeder pigs (range from 30 to 90 lbs) are purchased and then grown to market weight
