摘要
试验以仙湖肉鸭A系为研究材料,测定其49日龄的屠体性状及4项血脂指标,并探讨它们之间的关系。结果显示:公鸭血清甘油三酯(TG)与腹脂率呈中等的表型正相关,且相关关系显著;高密度脂蛋白(HDL-c)与胸肌率、瘦肉率呈显著的中等正相关;低密度脂蛋白(LDL-c)与胸肌率、腿肌率、瘦肉率均呈微弱的负相关,却与腹脂率、皮脂率呈弱的正表型相关,但它们相关关系不显著。母鸭TG与腹脂率呈中等表型正相关,且相关关系显著;HDL-c与胸肌率、瘦肉率呈弱的正相关、与腹脂率、皮脂率均呈弱的负相关;LDL-c与胸肌率呈中等的负相关,但相关关系未达到显著水平,LDL-c与腹脂率呈中等正相关,且相关关系显著;而血清胆固醇与各项屠体性状间的相关关系不密切。上述结果表明:血清中的TG可作为仙湖肉鸭腹脂率选择的辅助指标;HDL-c可作为公鸭胸肌率选择的参考指标;LDL-c也可作为母鸭腹脂率选择的重要参数。
Carcass traits and four blood lipid parameters of 49-day-age strain A of Xianhu meat ducks were measured to study the correlations between them. The results were as follows：for male ducks,there was a significant and moderate positive phenotypic correlation between triglyceride （TG） and abdominal fat rate;breast muscle rate and leg muscle rate were moderate,significant and positive correlation to high density lipoprotein（HDL-c）;low density lipoprotein（LDL-c）had a faint negative correlation with breast muscle rate,leg muscle rate,lean muscle rate and a faint positive correlation with abdominal fat rate and subcutaneous fat rate,both of which were insignificant. For female ducks,there was a significant and moderate positive phenotypic correlation between TG and abdominal fat rate;breast muscle rate,lean muscle rate had a faint positive correlation with HDL-c,abdominal fat rate,subcutaneous fat rate had a faint negative correlation with HDL-c;LDL-c had a moderate negative correlation with breast muscle rate;;LDL-c had a significant and moderate positive correlation with abdominal fat rate;there was no significant correlation between serum cholesterol and carcass traits. Conclusions could be drawn that TG in serum could be an assistant index for abdominal fat rate selection of Xianhu meat ducks,HDL-c for breast muscle rate selection of male ducks and LDL-c for subcutaneous fat rate selection of female ducks.
