Vet on call: Common birth defects in pigs

What you need to know:

  • Animals that give birth to many young ones and frequently like pigs, dogs and cats are good models for observing birth deformities.
  • The most common cause of birth deformities are genetic problems arising from breeding closely related lines of animals. This is termed inbreeding.
  • Furthermore, animals with one observable genetic defect may also be having other internal defects that only become apparent later in life.
  • Hermaphroditism occurs when pigs are born with both male and female reproductive traits and organs. Such animals grow to maturity but must not be bred.
