Summary

• These fetal pigs are unborn. When processing sows
  for meat, they are removed from the uterine horn
  and made available to science labs.
• They belong to the Sus scrofa species and the
  Order Artiodactyla.
• They are omnivorous, feeding on both plants and
  animals. The lifespan of a pig is 15 to 20 years
  and the body temperature is slightly higher than
  that of a human. Pigs are valuable experimental
  animals for study of effects of drugs and
  radiations.
