摘要: 通过采集内蒙古乌兰察布市四子王旗荒漠草原11种牧草,分别测定和计算它们的粗蛋白、粗脂肪、粗灰分、中性洗涤纤维、酸性洗涤纤维、可吸收营养物质总量、干物质采食量、干物质消化率、相对饲喂价值、相对牧草品质10项营养指标数据,并进行不同牧草营养价值综合评价。研究采用CRITIC客观赋权与GRA-TOPSIS综合评价模型相结合的方法,结果显示:禾本科中的三种牧草营养价值由高到低依次为羊草(Leymus chinensis)>短花针茅(Stipa breviflora)>无芒隐子草(Cleistogenes songorica);灌木、半灌木中的五种牧草营养价值由高到低依次为木地肤(Bassia prostrata)>驼绒藜(Krascheninnikovia ceratoides)>小叶锦鸡儿(Caragana microphylla)>冷蒿(Artemisia frigida)>狭叶锦鸡儿(Caragana stenophylla);杂类草中的三种牧草营养价值由高到低依次为糙苏(Phlomoides umbrosa)>银灰旋花(Convolvulus ammannii)>黄芪(Astragalus membranaceus)。

Abstract: By collecting 11 forage species from the desert steppe of Siziwang Banner, Ulanqab City, Inner Mongolia, we separately determined and calculated their crude protein, ether extract, crude ash, neutral detergent fiber, acid detergent fiber, total digestible nutrients, dry matter intake, dry matter digestibility, relative feeding value, and relative forage quality. A comprehensive evaluation of the nutritional value of different forages was conducted. The study employed a combined approach utilizing the CRITIC objective weighting method and the GRA-TOPSIS comprehensive evaluation model. The results of the study showed that the three forage grasses in the grass group, in descending order of nutritional value, were Leymus chinensis > Stipa breviflora > Cleistogenes songorica; the five forage grasses in the shrub and semi-shrub group, in descending order of nutritional value, were Bassia prostrata > Krascheninnikovia ceratoides > Caragana microphylla > Artemisia frigida > Caragana stenophylla; and the three forage grasses in the weedy group, in descending order of nutritional value, were Phlomoides umbrosa > Convolvulus ammannii > Astragalus membranaceus.
