【摘要】 为了确定干旱区蒲公英的营养价值和饲用性能，以种植两年的蒲公英，年刈割四茬的混合草粉为试验材料，分析其营养成分，并做为添加料饲喂“岭南黄”小公鸡育肥。结果显示，蒲公英的粗蛋白质含量是苜蓿（甘农3号）的93.08%，无氮浸出物含量是1.29倍，粗脂肪含量是1.49倍，粗纤维含量是48.87%，粗灰分含量是1.24倍；含有丰富的维生素维生素C、维生素E、VPP、β-胡萝卜素、维生素B₁、维生素B₂，其中维生素B₂质量分数最高；Na、Mg、Fe、K、Ca、Cu、Zn、P、Mn和Co等矿质元素质量分数较高，尤其是K元素的质量分数最高，且Ca和P含量比例是1:2.8，适合动物营养需求。蒲公英草粉添加到家禽日粮，鸡发病率降低20%和死亡率降低10%，以添加量为10%～20%效果最好。更多还原

【Abstract】 In order to determine the nutritional value and feeding performance of Taraxacum mongolicum in arid area,the mixed grass meal of which planted for two years and cut four stubbles per year was used as experimental material to analyze its nutritional components,and was used as additive to feed“Lingnan yellow”cockerel for felling. The results showed that the crude protein content of Taraxacum mongolicum leaves was 93.08% of that of Alfalfa(Variety name is Gannong. The crude protein content of Taraxacum mongolicum was 93.08% than that of alfalfa（Gannong 3）,the nitrogen free extract content was 1.29 times,the crude fat content was 1.49 times,the crude fiber content was 48.87%,the ash content was 1.24 times. Taraxacum mongolicum leaf was rich in vitamins VC,VE,VPP β-Carotene,VB₁ and VB₂,of which VB₂ was the highest mass fraction. The mass fraction of mineral elements,such as Na,Mg,Fe,K,Ca,Cu,Zn,P,Mn and Co were high,especially the mass fraction of K was the highest,and the content ratio of Ca and P is 1 :2.8,which was suitable for animal nutritional need. Adding Taraxacum mongolicum leaf powder to poultry diets could effectively reduce the incidence rate 20%of chicken and death rate 10%. The best dosage rate of diets was 10%-20%. Taraxacum mongolicum could replace the same amount of corn flour and promote healthy growth of broilers.更多还原
