The animal, Pig is Puerco or Cerdo.
Marrano is calling a person a Pig or Swine.
I think this topic has been covered before, a search might uncover extra information.
For my thoughts perhaps originally meaning 'pig' the animal it now seems to carry a rather derogative meaning:
Marranos or 'secret Jews' were Sephardic Jews, or Jewish people living in the Iberian peninsula, forced to convert to Catholicism-Christianity or be expelled from the Kingdoms of Castile and Aragon (Spain). This designation officially began in 1492 with the Castilian Alhambra Decree, reversing protections in the Treaty of Granada (1491), and used for conversos, or ' confirmed converts', at first. However, soon Marranos was used for people that continued to practice Judaism secretly, crypto-Jews preserving their Jewish identity, 'the secret Jews' or judíos escondidos (in Hebrew Anusim). Marrano in 15th century Spanish first meant pig, from the ritual prohibition against eating pork, practiced by both Jews and Muslims. During the Spanish Inquisition Marrano acquired the pejorative meanings: "filthy-pig" (sucio); swine (sin escrúpulos); and "filthy-dirty". In contemporary Spanish the word is no longer associated with Jews. In contemporary Portuguese the word refers only to crypto-Jews, with marrão meaning the animal pig or swine.
Although having said that it's interesting to note that 'swine flu' is referred to as 'la gripa del marrano' so perhaps the meaning is regional and would be offensive in some areas but still carry the meaning of just the animal in others. MHO only.

Right marrano means pig the animal?
