Abstract: In order to explore the immunologic difference between Chinese indigenous and exotic pigs, immune indexes, including serum levels of IgG, IL-12, IFN-γ, neutrophil function and total white blood cell count, were compared between Songliao black pig and Large white pig, partial production index were detected also. The results indicated that total white cell count, as well as neutrophil function, levels of IL-12 and IFN-γin culture supernatant of peripheral blood mononuclear cell were similar between the two pig breeds (P＞0.05). The serum levels of IgG was significant between Songliao black pig and Large white pig（P＜0.05）, IL-12 and IFN-γ of Songliao black pig were very significantly higher than that of Large white pig（P＜0.01）. There were no difference between two breeds in birth weight, weaning weight and others(P＞0.05). The 180-days-aged weight of Songliao black pig was significantly lower than that of Large white pig (P＜0.01). The results were helpful to explore the immunologic mechanism of difference of disease resistance between Chinese indigenous and exotic pigs.
