摘　　要：用京白蛋鸡研究了开产前饲喂高脂日粮对血浆极低密度脂蛋白含量的影响，及对开产后产蛋性能的影响。结果表明蛋鸡开产前饲喂高脂日粮可使试验鸡血浆极低密度脂蛋白水平显著增加。在蛋鸡开产后对其生产性能有良好的影响，使产蛋量（克／只日）和蛋重显著增加（Ｐ＜０．０１），产蛋率也有增加的趋势，但不显著（Ｐ＞０．０５）。This study was conducted to determine the effect of high lipid diet on the plasma very low density lipoprotein(VLDL) concentration and the laying performance with Jin-bai hens before sex mature.The result showed that high lipid diet made the plasma VLDL concentration increased,and it had a good affection on laying performance after sex mature,the egg production (egg mass, g./hen.day) and egg weight were increased significantly(P<0.01),and the laying rate(%) had the trend to be increased.
