Blood samples were taken from birds,from a commercial line of broiler chicken,being in a fully fed staternand in fasting state for 2,4, 6 hours respectively at 49 d of age and plasma very low density lipoproteinrn(VLDL) concentration was measured with turbidimetric assay. The experiment results showed that the varia-rntion coefficients of plasma VLDL concentration mersured at four different times were 58.11％, 74.39％, 69.rn70％ ,47. 83％ ,respectively for male broilers,and 41.82％,60.87％. 59.26％,50. 0％for female broilers re-rnspectively. Plasma VLDL concentration decreased with the fasting time. There was a significant positive phe-rnnotypic correlation between abdominal fat weight,percentage of abdominal fat and plasma VLDL concentra-rntion for the birds being in fully feeding state,and the correlation decreased or no longer existed for the biredrnbeing in fasting state. The conclusion was that for practically application of plasma VLDL content selected inrnbroiler chicken breeding,blood samples should be collected from birds being in feeding state.
