摘要： 试验旨在研究在日粮中添加3%、5%亚麻油对血清甘油三酯、总胆固醇、高密度脂蛋白胆固醇和低密度脂蛋白胆固醇的含量及对肝脏脂肪酸合成酶、腹脂脂蛋白脂酶活性和肉鸡腹脂沉积的影响。选择216只21日龄罗斯308商品代肉用母雏，随机分为3组，每组6个重复，每个重复12只。3组分别饲喂基础日粮（对照组）、添加3%亚麻油和5%亚麻油日粮，试验期3周。试验结果表明，血清甘油三酯水平在各组之间差异不显著（P>0.05），与对照组相比，3%、5%亚麻油组总胆固醇水平上升（P>0.05），高密度脂蛋白胆固醇水平下降（P>0.05），3%亚麻油组显著提高了血清低密度脂蛋白胆固醇水平（P<0.05）。各处理组降低了肝脏脂肪酸合成酶和腹脂脂蛋白脂酶活性（P>0.05），但与腹脂沉积的趋势并不一致。

Abstract: An experiment was carried out to evaluate the effect of 3%, 5%linseed oil in diets on the content of TG, TC, HDLC, LDLC in serum and activities of FAS in liver, LPL in abdominal fat and body fat deposition of broilers. Two hundred sixteen 21dayold Ross 308 female broilers were randomly divided into three treatments with each treatment replicated 6 times with 12 birds for replicate,which were fed control diets， 3% linseed oil and 5% linseed oil for 3 weeks. The results showed that serum levels of TG were not significantly different among treatments (P>0.05). The TC level was slightly higher than the control (P>0.05) and LDLC levels slightly lower than the control (P>0.05). The HDLC level in 3% LO was significantly higher than the control (P<0.05). FAS activity in liver and LPL activity in abdominal fat were lower in 3%, 5% linseed oil than the control (P>0.05) which is disagreement with the tendency of abdominal fat deposition.

Key words: broilers; linseed oil; fatty synthetase activity; fat deposition
