摘要
不同品种鸭血浆VLDL水平有一定的特异性。产蛋期母鸭血浆VLDL浓度高于相应品种公鸭4．48-17．65倍。产蛋率超高的母鸭其VLDL水平越高，而变异系数超低。7周龄肉鸭VLDL浓度与脂肪率和体重有一定正相关，与瘦肉率有一定程度负相关。
Plasma VLDL content had genetic speaciality in different duck specs. The female duck VLDL content during laving pened was 4. 48-17 .65 times higher than that of male duck. The higher egg-laying rate the female duck had, the higher content and lower coefficient of variability the plasma VLDLwas. There were active Correlations betWeen VLDL content with body weigh and fat rate,and negative correlation with lean rate in 7-week-old meat duck.
