AB  - In this study, haematological traits, lysozyme concentration and T lymphocyte subpopulation as markers of innate immunity were detected and compared among Landrace, Large White and a chinese indigenous breed, Songliao Black pig. The animals were of the same age and kept under the same environmental conditions to reduce non-genetic variation in immune traits; they were all apparently healthy and were vaccinated by CSF live vaccine at 21 days of age. Except LY%, MO%, CD4<SUP>¯</SUP>CD8<SUP>¯</SUP>% and RDW, the other detected immune traits were significant difference between before (20 days) and after vaccination (35 day). While the values of MCV, MCH, MCHC, MO%, CD4<SUP>+</SUP>CD8<SUP>+</SUP>% and CD4<SUP>+</SUP>CD8<SUP>+</SUP>/CD4<SUP>¯</SUP>CD8<SUP>+</SUP> values decreased after vaccination, the others increased. The values of WBC, GR, LY, MO, CD4<SUP>+</SUP>CD8<SUP>¯</SUP>% and CD4<SUP>+</SUP>CD8<SUP>+</SUP>% were significant difference among Large White, Landrace and Songliao Black pig (p&lt;0.05). Our analysis confirms that Songliao Black pig has better innate immune level than Landrace and Large White. The animal resource population was suggested to be appropriate to investigate further the QTL and genes contributing to differences on these innate immune traits in pigs.
