It is very surprising that in Denmark one can easily find a pig as compare to a human being. The researchers have proved that the country has approximately 5.4 million human inhabitants, but each year it exports 25 million pigs. In simple terms it has been assumed that outnumber of pig and residents is nearly 5:1.
A joint project between the Danish Committee of Pig Breeding and Production, and the Chinese Academy of Sciences, delivered nearly four million pieces of genomic information on five breeds of pigs because of the great availability of pigs in Denmark. Scientists offer more precise way of testing medications and surgical techniques, since the pig is so similar to the human. Infact the pig hearts and other organs have been eyed for possible use in human transplants but there are fewer rejection problems related to tissues, than there are to living, functioning organs.
