为筛选适宜在黔西南岩溶区生长的优良饲料灌木以促进当地畜牧业的发展,提高农民收入,本研究对生长在黔西南州的3科19属27种饲料灌木的6种常规营养成分进行了定量与相关分析,结果表明,1)马棘和小构树均满足典型蛋白质饲料的要求;2)科别间粗灰分均值差异极显著,桑科显著高于其他2科.科别间无氮浸出物均值差异显著,豆科极显著低于蔷薇科,显著低于桑科;3)粗纤维与无氮浸出物、粗脂肪、粗蛋白、粗灰分均呈显著或极显著的负相关,其含量过高会影响饲料灌木的整体营养价值.

Six nutrient contents of 3 families with 19 genera and 27 species of fodder shrubs were measured in order to select suitable fodder shrubs to grow in the karst areas in Southwest Guizhou. And thereby promote the development of local animal husbandry and increase the income of farmers, then dates are made quantitative and correlation analysis. 1) Indigofera pseudotinctoria and Broussonetia kazinoki meet the requirements of a typical protein feed. 2) Mean values of ASH and NFE showed extremely significant difference among three families: The Moraceae had significantly higher ASH content than the other two families. The Leguminosea had significant lower NFE content than the Moraceae and Rosaceae; 3) There were high negative correlation coefficients between CF and NFE,EE,CP,and ASH,so the CF content strongly affects the overall nutritional value of fodder shrubs.
