Fetal Pig Dissection
2
Background Information

• These specimens are NOT raised for dissection
  purposes. They are salvaged from pregnant sows
  at slaughter for food.
• They have been embalmed via the umbilical cord.
• Arteries and veins also injected with latex (red
  arteries, blue veins).

3
Objectives

• Perform a whole body dissection of a vertebrate
  like ourselves
• Many similarities exist!
• Muscular, digestive, respiratory, circulatory,
  reproductive systems
• Identify the major anatomical features of the pig
• Understand the relationships between form
  function of each organ, each system, and how all
  systems interconnect homeostasis!

4
Objectives

• Determine the sex of pig using external
  anatomical landmarks
• Determine age of fetus via length (fetal pig
  gestation time time in the uterus)
• Gestational time for pigs ranges between 112-114
  days
• Length specifies age
• 11 mm - 21 days 17 mm - 35 days
• 2.8 cm - 49 days 4 cm - 56 days
• 22 cm - 100 days 30 cm -- birth
