Abstract: The brown shell egg-type chickens had been used in this study to determine its plasma very low-density lipoprotein (VLDL) concentration. After two generation divergent selection for plasma VLDL concentration, plasma high and low VLDL concentration groups had been established. The influences of divergent selection for plasma VLDL concentration on some correlated traits had been found. In plasma low VLDL concentration group, body weight, egg weight, albumin weight were slightly higher than that of the plasma high VLDL concentration group, while abdominal fat weight, yolk weight, ratio of yolk to egg weight, egg cholesterol content, egg cholesterol weight were lower than that of the plasma high VLDL concentration group(p>0.05). Only the difference of yolk and egg weight ratio was very significant (p<0.01) according to experimental results. The correlation coefficient between plasma VLDL concentration and these traits had been estimated, the estimated correlation coefficient between plasma VLDL concentration and egg weight, albumin weight were negative, however the positive estimated correlation coefficient between plasma VLDL concentration and body weight, abdominal fat weight, yolk weight, ratio of yolk to egg weight, egg cholesterol content, and egg cholesterol weight had been found, indicating that the selection for low egg cholesterol group using plasma VLDL concentration as an indirect selection index was practicable, and further selection and research are necessary.

Key words: very low density lipoprotein, cholesterol, egg-type chicken, very low density lipoprotein, cholesterol
