Why is the skin of your pig yellow.?

Why is the skin of your pig yellow.? Jaundice, or icterus is yellow coloration of white connective tissue in the body, skin or eye sclera, the latter being the only sign in pigs. The yellowing/jaundice results when there is an increase of biliary salts in the blood and it takes one of three forms. Pre-hepatic jaundice, or hemolytic icterus, occurs due to massive blood destruction that overwhelms the detoxifying capacity of the liver. Hepatocellular icterus comes from direct liver injury, and post-hepatic icterus is caused by obstruction of biliary drainage. Several infections can affect directly the blood or the liver causing yellowing these are: Leptospira (mainly fetuses), mycoplasma, E. coli and Salmonella. In all cases other signs can help to address infective causes. Ascaris suum can also cause icterus through direct parasitosis of the liver with later migration to the lungs. At the abattoir white spots are evident in the liver.
