肉鸭血浆脂类浓度与体脂含量关系的研究

以42日龄樱桃谷肉鸭(公、母各30只)为试验素材,测定其血浆甘油三酯、磷脂、胆固醇、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)和极低密度脂蛋白(VLDL)的浓度,并屠宰测定其皮脂重(率)、腹脂重(率)和胸、腿肌肉的含脂率.结果表明公鸭血浆胆固醇、LDL、HDL和VLDL浓度极显著高于母鸭;肉鸭血浆胆固醇与甘油三酯呈显著相关,与HDL、LDL、磷脂呈极显著相关,血浆甘油三酯与LDL、VLDL呈极显著相关.HDL与LDL、磷脂呈极显著相关;LDL与磷脂、VLDL呈极显著相关;血浆胆固醇、甘油三酯、HDL、LDL、磷脂浓度与体脂性状相关均较弱,而血浆VLDL浓度与皮脂重、皮脂率、腹脂重呈显著负相关.

STUDY ON THE RELATIONSHIP BETWEEN PLASMA LIPIDS CONCENTRATION AND BODY FATNESS TRAITS IN MEAT TYPE DUCKS

Plasma lipids concentration and the carcass fatness traits of 42-day-old Cherry Valley ducks were measured. The results showed that the concentrations of plasma triglyceride (TG), phospholipid (PL), total cholesterol (CHO), high density lipoproteins (HDL), low density lipoproteins (LDL) and very low density lipoproteins (VLDL) were significantly higher in male than those in female ducks. There were significant correlation between plasma CHO and TG concentrations, and very significant correlation between plasma CHO and HDL, LDL, PL concentrations, significant correlation between TG and LDL, VLDL concentrations, significant correlation between DHL and LDL, PL concentrations, very significant correlation between LDL and PL, VLDL concentration. No significant correlation between plasma CHO, TG, HDL, PL concentrations and body fatness was found, but there were significant negative correlation between plasma VLDL concentrations and skin weight, the percentage of skin,abdominal fat weight.
