Abstract: The present invention relates to screening of the expression profile of growth specific genes in swine and a functional cDNA chip using the same and provides nucleotide sequences of novel growth factors related to the growth in the muscle and fat tissues of swine. Also, the present invention provides a functional cDNA chip for screening and function analysis of growth specific gene according to breeds and tissues of swine prepared by integrating only the growth specific genes obtained as described above. Therefore, the functional cDNA chip for screening and function analysis of growth specific gene according to breeds and tissues of swine can be used in the swine improvement and breeding of a new breed.

Abstract: The present invention relates to novel growth-related genes derived from pig and provides novel growth-related genes DNA which are involved in incensement of growth rate of pig using the microarray technology. Therefore, the growth-related genes derived from pig according to the present invention can be used in feeds for increasing the daily body weight gain of pig or applied in genetic improvement of pig with excellent growth performance. Thus, the present invention is very useful for the hog raising industry.
