Sus scrofa (Pig)

The pig (Sus scro­fa) is a mem­ber of the artio­dactyls, or cloven-hoofed mam­mals, which are an evo­lu­tion­ary clade dis­tinct from the pri­mates and rodents. Pigs exist in both fer­al and domes­ti­cat­ed pop­u­la­tions that have dis­tinct phe­no­types and kary­otypes. The hap­loid genome of the domes­ti­cat­ed pig is esti­mat­ed to be 2800 Mb. The diploid genome is orga­nized in 18 pairs of auto­somes and two sex chro­mo­somes.Sus scro­fa is an impor­tant mod­el organ­ism for health research due to par­al­lels with humans. Swine are omni­vores and their diges­tive phys­i­ol­o­gy is sim­i­lar to humans. Sim­i­lar­i­ties between humans and pigs also exist in renal func­tion, vas­cu­lar struc­ture, and res­pi­ra­to­ry rates. Pigs are used as mod­el organ­ism in many areas of med­ical research includ­ing obe­si­ty, car­dio­vas­cu­lar dis­ease, endocrinol­o­gy, alco­holism, dia­betes, nephropa­thy, and organ trans­plan­ta­tion. Pigs are also agri­cul­tur­al­ly impor­tant, as pork is a lead­ing source of pro­tein world­wide.
