摘　　要：试验旨在揭示几种灌木类粗饲料主要营养成分含量、饲草品质及饲用价值,同时分析同一植物不同部位和不同生长阶段的营养价值,为灌木类粗饲料资源的高效利用提供理论依据。选取鄂尔多斯杭锦旗地区柠条、小果沙棘、大果沙棘的茎秆、叶、果实等饲料原料,测定主要营养成分含量,并进行饲草品质及饲用价值的评定。结果表明:柠条的当年生新长带叶嫩枝营养价值、饲草品质和饲用价值最高,2年生带叶嫩枝次之。小果沙棘的2年生叶子的营养价值、饲草品质和饲用价值最高,2年生细枝带叶次之。大果沙棘当年生细枝带叶的营养价值、饲草品质及饲用价值最高,2年生细枝带叶次之。综上,从充分利用角度考虑,柠条2年生带叶嫩枝、小果沙棘2年生细枝带叶以及大果沙棘2年生细枝带叶更适合作为高营养价值粗饲料原料进行开发利用。This experiment aims to reveal the content of main nutrients,forage quality,and feeding value of several shrub-type coarse forages,as well as analyze the nutritional value of different parts and growth stages of the same plant,providing theoretical basis for the efficient utilization of shrub-type coarse forage resources.Caragana korshinskii,Hippophae rhamnoides subsp.sinensis,and Hippophae rhamnoides were selected as feedstock in Hangjin Banner,Ordos,and the content of main nutrients and evaluating the forage quality and feeding value were measured in this experiment.The results showed that:the newly grown tender shoots with leaves of Caragana korshinskii in the current year had the highest nutritional substances,forage quality,and feeding value,followed by the 2-year-old tender shoots with leaves.The 2-year-old leaves of Hippophae rham⁃noides subsp.sinensis had the highest nutritional substances,forage quality,and feeding value,followed by the 2-year-old thin branches with leaves.The 1-year-old thin branches with leaves of Hippophae rhamnoides had the highest nutritional substances,forage quality,and feeding value,followed by the 2-year-old thin branches with leaves.In summary,considering the full utilization,the 2-year-old tender shoots with leaves of Caragana korshinskii,the 2-year-old thin branches with leaves of Hippophae rhamnoides subsp.Sinensis,and the 2-year-old thin branches with leaves of Hippophae rhamnoides are more suitable for development and utilization as high-nutritional-value coarse forage materials.
