Why do pigs need a large liver?
With the higher demand for energy around farrowing and milk production increases, the liver plays a crucial role (Figure 1). This greater need for energy causes an increase in body fat and protein mobilization that can result in metabolic disorders.
What does the liver do in a fetal pig?
The liver filters out poisons and chemicals and recycles hemoglobin from the bloodstream. When the pig is a fetus in its mother's uterus, the liver contributes to the production of blood cells.

How are fetal pigs and humans different?
pigs are quadrupedal and humans are bipedal. The fetal pig uterus is of a type called bicornate, compared to the simplex human uterus. This means that the pig uterus has two large horns in addition to the body. These horns are sometimes confused with the much smaller Fallopian tubes.
How does a pig's large intestine differ from a human's?
