摘　　要：本试验旨在研究饲粮中添加沙棘果渣对育肥羔羊生长性能、器官指数、血清生化指标和肌内脂肪酸组分的影响。选取24只3月龄杜泊×小尾寒羊杂交公羔[(25±1)kg],随机分为4组,每组6只羊。各组分别饲喂含有0(对照)、10%、20%和30%沙棘果渣的试验饲粮。试验期50 d。结果表明:1)10%和20%水平组羔羊的宰前活重显著高于对照组和30%水平组(P<0.05),10%水平组羔羊的平均日增重显著高于其他各组(P<0.05),20%水平组羔羊的平均日采食量显著高于其他各组(P<0.05),10%水平组羔羊的料重比显著低于其他各组(P<0.05)。2)30%水平组羔羊的肝脏、脾脏指数显著高于其他各组(P<0.05),网胃指数显著低于其他各组(P<0.05)。10%、20%和30%水平组羔羊的大肠和小肠指数显著高于对照组(P<0.05)。3)30%水平组羔羊的血清高密度脂蛋白(HDL)含量显著高于其他各组(P<0.05),10%、20%和30%水平组羔羊的动脉粥样硬化指数(AI)显著低于对照组(P<0.05),10%、20%和30%水平组羔羊的血清总抗氧化能力(T-AOC)、谷胱甘肽过氧化物酶(GSH-Px)和超氧化物歧化酶(SOD)活性显著高于对照组(P<0.05),30%水平组羔羊的血清谷草转氨酶(AST)、谷丙转氨酶(ALT)、乳酸脱氢酶(LDH)活性及肌酐(CRE)和尿素氮(UN)含量显著高于其他各组(P<0.05)。4)10%、20%和30%水平组羔羊的背最长肌中亚油酸、反油酸、花生四烯酸、总多不饱和脂肪酸(ΣMUFA)和总不饱和脂肪酸(ΣUFA)比例显著高于对照组(P<0.05),油酸、总饱和脂肪酸(ΣSFA)和总单不饱和脂肪酸(ΣPUFA)比例显著低于对照组(P<0.05)。由此可见,育肥羔羊饲粮中添加沙棘果渣有利于其生长发育和生长性能的提高,适宜添加水平为10%~20%。The objective of the this study was to investigate the effects o f dietary sea buckthorn pomace on growth performance, organ indexes, serum physiological parameters and intramuscular fatty acid composition of fattening lambs. Twenty-four 4-month-old Dorperxsmall thin-tailed crossed ram lambs [（25±1） k g ] were selected and randomly divided into four groups with 6 sheep per group. Sheep in the four groups were fed the experimental diets which contained 0 （control）, 10% , 20% and 30% sea buckthorn pomace, respectively. The experiment lasted for 50 days. The results showed as fo l low s： 1） the slaughter body weight o f lambs in 10% and 20% groups was significantly higher than that in control group and 30% group （P〈0.05） , the aver-age daily gain of lambs in 10% group was significantly higher than that in other groups （P〈0.05） , the average daily feed intake of lambs in 20% group was significantly higher than that in other groups （P〈0.05） , the ratio of feed to gain of lambs in 10% group was significantly lower than that in other groups （P〈0.05）. 2） The l iv -er and spleen indexes of lambs in 30% group were significantly higher than those in other groups （P〈0.05）, and the reticulum stomach index was significantly lower than that in other groups （P〈0.05）. The large intes-tine and small intestine indexes of lambs in 1 0 % , 2 0 % and 3 0 % groups were significantly higher than those in control group （P〈0.05）. 3） The serum high density lipoprotein （H D L ） content o f lambs in 30% group was significantly higher than that in other groups （P 〈0.05） , the atherosclerosis index （ AI ） o f lambs in 10% , 20% and 30% groups was significantly lower than that in control group （P〈0.05） , the total antioxidant capac-ity （T-AOC ） and activities of glutathione peroxidase （GSH-Px） and superoxide dismutase （ SOD） in serum o f lambs in 10% , 20% and 30% groups were significantly
