- feed efficiency
- carcass traits (loin eye area & back fat)
6
Q
Swine Industry
A
- Boar Stud
- Gestation
- Farrowing
- Nursery
- Feeder/finisher
7
Q
Boar Stud
A
- individual boar housing
- collection pens
- extremely high bio security
(Isolated, seperate, quarantine, water purification, air filtration)
8
Q
Gestation/Breeding
A
- gestation barn (weaning to 110/112 of gestation)
heat check, breed sows, sow thermal comfort - farrowing barn
houses sows in crates, sow comfort, baby pig safety, thermal environment, worker safety and comfort
9
Q
Reproduction
A
- sow
estrous cycle = 21 days
estrus period = 15-96 hours
infertile estrus = 1-3 days post parturition
10-25 ovarian are shed at each estrus
10
Q
Nursery
A
*entry at approx. 15 pounds and 21 days of age
* exit at approx. 50 pounds and 70 days of age
- high bio security
- thermal comfort
- comfortable flooring (heated zones)
- weaned pig feeders to aid feeder
11
Q
Finishing
A
- entry at approx. 50 pounds and 70 days of age
- exit at approx. 280 pounds and 180 days of age
- least bio security
- natural or mechanical ventilation
- feed and water access
- stocking density and pig space
12
Q
Wean to finish
A
- entry at approx. 12 pounds and 21 days of age
- exit at approx. 280 pounds and 180 days
- skips nursery phase
Advantages= less movement & improved lifetime
Disadvantage = disease control & suitability
