Abstract:

In the present study,Dapulian piglets (n=124),one indigenous breeds with higher disease resistance of North China,and Landrace (n=187),one commercial breed with lower disease resistance were used,routine blood traits and T-lymphocyte subpopulation traits of these piglets were determined by automatic blood cell analyzer and flow cytometry.Additionally,we performed analyses of breeds and litter effect on these traits in piglets.The results indicated that the most of the blood routine traits had small variation range,with the average variation coefficient of 22.92%,while the variation coefficient of mature T-lymphocyte cells (with average of 44.5%) were smaller than those of immature ones (with average of 112.77%).Comparison between the two breeds,except for RBC,HGB,LY,MID and PLT,the other 14 traits of routine traits were significantly different at 0.01 level.As respective for the T-lymphocyte subpopulation traits,except for CD4+CD8-CD3-,CD4+CD8+CD3- and CD3+,the other 7 traits were significantly different at 0.05 or 0.01 level.The piglets used in the study were sampled from 13 brood Dapulian sows and 28 brood Landrace sows,and analyses indicated that the sow effects on all the hematological traits were all significant at 0.05 or 0.01 level.To our knowledge,this is the first study aimed at determining and analyzing the routine blood traits and T-lymphocyte subpopulation traits of Dapulian and Landrace piglets at population level.Results of the study may provide important information for understanding the difference between the indigenous and commercial breeds and mining the characteristic of indigenous breed.
