【摘要】 试验取180日龄罗曼褐壳蛋鸡168羽,随机分为2组,对照组饲喂基础日粮,试验组在基础日粮中添加1.5%蜂花粉,于212日龄每组随机取鸡蛋30枚,测定平均蛋重、蛋壳厚度、蛋形指数、蛋黄的色泽,鸡蛋的粗蛋白、粗脂肪、胆固醇及部分微量元素的含量,研究蜂花粉对蛋品质的影响。结果:试验组蛋壳厚度增厚9.22%(P<0.01),蛋黄重量提高6.89%(P<0.05);蛋黄的色度显著高于对照组(P<0.05),胆固醇含量降低29.18%,差异极显著(P<0.01)。微量元素含量差异不显著(P>0.05)。结果显示:蜂花粉可改善蛋品质。更多还原

【Abstract】 A total of 168 180-day-old Roman Brown layers were randomly divided into 2 groups.The control group was fed on the basic diet,and the experiment group supplemented 1.5% bee pollen.30 eggs were selected randomly at 212d of each group,the average egg weight,eggshell thickness,egg-shaped index,egg yolk chromaticity,the content of crude protein,crude fat,cholesterol and trace elements were measured to study the effects of bee pollen on egg quality of layers.The results were as follows: compared with experiment group,thickness of eggs increased by 9.22%(p<0.01).The weight of egg yolk increased by 6.89%(p<0.05).The yolk’s color of experiment groups increased higher than control groups(p<0.05),but the content of cholesterol was reduced by 29.18%,extremely significantly(p<0.01).The content of trace elements were not significant from that of control groups.The results showed that the bee pollen could improve egg quality.更多还原
