摘要: 2008年9月—2009年7月,对江苏大丰麋鹿国家级自然保护区野放麋鹿生境中食源植物芦苇(Phragmites australis)和互花米草(Spartina alterniflora)的营养成分变化进行了研究;并对5条样线上的样点分别采样,对互花米草和芦苇的粗蛋白、酸性洗涤纤维及中性洗涤纤维分别进行了测定。结果表明:互花米草粗蛋白含量为8.09%,酸性洗涤纤维为36.34%,中性洗涤纤维为69.82%;而芦苇的年度粗蛋白含量为2.84%,酸性洗涤纤维为45.99%,中性洗涤纤维为77.78%;大丰野放麋鹿生境中互花米草的营养成分含量比芦苇高,可见,互花米草是野放麋鹿的喜食植物。

Abstract: During September 2008 to July 2009, a comparative study was made on the nutritional components of Phragmites australis and Spartina alterniflora in the Dafeng National David’s Deer (Elaphurus davidianus) Reserve of Jiangsu. The samples were collected from the sampling sites along 5 sampling lines, with the crude protein, acid detergent fiber (ADF), and neutral detergent fiber (NDF) analyzed. In the Reserve, the crude protein, ADF, and NDF contents of S. alterniflora were averagely 8.09%, 36.34%, and 69.82%, and those of P. australis were averagely 2.84%, 45.99%, and 77.78%, respectively, suggesting that S. alterniflora had a higher nutritional value than P. australis, and thus, David’s Deer would prefer to S. alterniflora rather than to P. australis.
