| 摘 要： | 选用288只30周龄健康固始母鸡,随机分为4组,分别饲喂添加不同共轭亚油酸(0、0.5%1.0%和2.0%)的饲粮,经过6周饲养后测定蛋品质及鸡血清指标。结果表明:随着共轭亚油酸添加量的增加,蛋黄总胆固醇和总甘油三酯显著减少(P<0.05)。当共轭亚油酸添加量达到2.0%时,能显著增加蛋黄重和改善蛋黄色泽(P<0.05)。鸡血清中的总胆固醇和极低密度脂蛋白随着共轭亚油酸添加量的增加,有先增大然后减小的趋势,差异达到显著水平(P<0.05)。

| Abstract: | A total of 288 30-week-old Gushi layers were randomly divided into four groups and maintained in individual laying cages throughout 6 weeks of the experimental period. The layers were assigned to four treat-menu that consisted of commercial layer diets containing 0,0.5%,1.0%,2.0%. The results showed that CLA reduced TC and TG of yolk (P<0.05). Egg mass, egg shape index and Haugh units were not influenced by the dietary of CLA. Hens fed 2% dietary of CLA increased yolk weight and yolk color (P<0.05). The TC and VLDL-C increased at the first and then decreased as conjugated linoleic acid to add volume, reaching a significant difference (P<0.05). |
