摘要
在对云南 7种豆科灌木树种分布和适生环境生态习性了解的基础上 ,测定了这 7个树种叶片的常规营养成分、微量元素、氨基酸等的含量 ,并进行了动物饲喂试验。结果表明 :7种豆科灌木树种叶片营养成分含量均高于谷物类饲料 ,其叶片粗蛋白含量高于 13% ,且微量元素、氨基酸含量丰富 ,钙磷比适宜 ,具有较高的营养价值。7种豆科灌木的叶粉按 5 %比例用于 0～ 30日龄肉用仔鸡日粮中对雏鸡的健康无不良影响 ,可直接用于鸡的日粮当中。其中 ,多花 艹抗 子梢、波叶山蚂蝗、毛叶猪屎豆、毛叶秧青和白花羊蹄甲叶粉的蛋白质利用率较高 ,表明其蛋白质品质较佳 ,具有较好的饲用价值。
The distribution and suitable habitats of seven Leguminosae species were reviewed. In order to learn the value of the tested shrub species as fodder, the contents of nutrient components, microelements and amino acids were measured, and the experimentation of feeding animals was conducted as well. The experimental results show that the contents of seven tested species are all higher than that of normal crops, taking the content of gross protein as an example, content in those tested shrub species is averagely 13 % higher than normal crops as fodder. Besides, tested Leguminosae species enjoyed the characteristics of high content microelements, high content amino acids, proper proportion of Ca to P, the nutrient value is quite promising. The experimentation of leaf powder feeding indicates that 5 % of leaf powder mixed in normal food of chickling will not bring any negative effect, therefore, the leaf powder can be directly used in daily food of chickling. Among the shrub species tested, the protein utilization ratios of Campylotropis polyantha,Desmodium sequax,Crotalaria lonchophylla,Dalbergia yunnanensis and Bauhinia variegata are desirable, which indicates the protein qualities of these species are promising, with high fodder value.
