| 摘 要： | 本试验旨在研究饲粮中添加大豆磷脂(SL)对产蛋鸡生产性能和鸡蛋磷脂含量的影响.选用360只22周龄健康产蛋鸡,随机分为5个处理,每个处理6个重复,每个重复12只鸡.5种试验饲粮中分别添加0、0.5%、1.0%、2.0%和4.0%的SL.试验期4周.试验结果表明:1)0.5%SL组平均蛋重最大(P>0.05),1.0%SL组平均日采食量最低(P>0.05),1.0%和2.0%SL组的料蛋比较低(P>0.05),均显著低于对照组(P<0.05),产蛋率以0.5%组最高(P>0.05),即饲粮中添加0.5%～2.0%的SL可改善产蛋鸡的生产性能;2)饲粮添加SL可以降低鸡蛋蛋黄水分含量(约1.7个百分点)(P>0.05)、1.0%、2.0%和4.0%SL组的蛋黄粗脂肪含量显著高于对照组(P<0.05);1.0%、2.0%和4.0%SL组全蛋中总磷脂显著高于对照组(P<0.05),1.0%和2.0%SL组蛋黄中总磷脂含量显著高于对照组(P<0.05),同时蛋黄胆固醇含量略有增加(P>0.05);1.0%、2.0%和4.0%SL组蛋黄和全蛋中磷脂酰胆碱(PC)含量显著高于对照组(P<0.05);2.0%SL组磷脂酰乙醇胺(PE)最高,但各组间差异不显著(P>0.05);PC/PE随饲粮SL添加量的增加而线性升高,0.5%、1.0%和2.0%SL组均显著高于对照组(P<0.05),4.0%SL组显著高于其他组(P<0.05).结果提示,饲粮添加一定水平的SL可改善产蛋鸡的生产性能,提高鸡蛋中总磷脂和PC含量.

| Abstract: | A trial was conducted to study the effects of dietary supplementation with soy-lecithin(SL) on the performance and phospholipid contents in eggs of laying hens.Three hundred and sixty healthy 22-week-old laying hens were randomly divided into five groups with six replicates in each group and twelve laying hens per replicate.The laying hens were fed for 4 weeks with diets containing 0,0.5%,1.0%,2.0% and 4.0% SL,respectively.The results showed that 1) the average egg weight in 0.5% SL group was the highest of... |
