- country separated from Europe, Mexico and Africa
- climate
Most common source of disease is?
new arrivals
When bringing in new arrivals what should you do?

Other ways disease can enter a farm
- introduction of pigs carrying disease
- semen from boar stud
- trucks, equipment (contaminated with manure)
- contaminated feed
- rats, mice, birds, dogs and cats
- people (directly ie influenza or contaminated boots)
- aerosol- virus particles blown from neighboring farm
CAZ=?
controlled access zone
- pig farm yard
- -building and driveway
- access limited
RAZ=?
restricted access zone
- labeled with signs, locked doors
- where pigs are housed
- wash hands or shower
- change from street clothes into barn boots and coveralls
Biosecurity: vehicles
- can be contaminated by pig manure from other farms
- ensure trucks that have been to other farms have been cleaned
- don’t allow vehicles near barn
- have dead-stock pick-up at end of lane

- sows with larger litters
- fat sows
- hot weather
Splay leg birth deficiency
weankess
- not very mobile
- hard to compete with others
- will die because won’t get enough food for energy (hypoglycemia) or colostrum to fend off pathogens
Major causes of pre weaning mortality
management (crushing of piglets from not using farrowing crates and non-slip flooring)
-chilling- low viability guy will die of hypothermia- have no fat stores at birth
-starvation
Disease
-diarrhea
Piglet processing includes:
iron administration (prevents anemia)
clipping of needle teath
castrate males
dock tails
