Pregnancy
Fetal pigs do not have teeth developed in the womb. They only start developing teeth after birth.
During the 4th month, the first month of the second trimester, the greatest amount of fetal growth occurs.
The fetal mass increases at the greatest rate between weeks 9 to 14 of pregnancy. This period is known as the "growth spurt" stage of fetal development, where the baby's organs and body structures rapidly form and grow.
Fetal lungs are not functioning; no organism can start to breathe while immersed in amniotic fluid. Lungs only begin to function at birth.
Pigs have a gestation period of 114 days.
