互花米草的饲用价值分析

Spartina alterniflora from Min River Estuary Wetlands-A New Source for Forage

摘要: 分析不同收割时期闽江口湿地互花米草的营养成分,确定最佳收获期,并探讨互花米草的饲用价值。结果表明,互花米草的最佳收获期是6~9月的营养生长期,在此期间的互花米草粗蛋白13.57%、粗脂肪3.04%、钙0.34%、磷0.18%、天冬氨酸1.37%、谷氨酸0.75%、中性洗涤纤维58.78%、酸性洗涤纤维34.47%、NaCl含量3.51%。互花米草不仅氨基酸组成成分齐全、含量丰富,饲料相对价值(RFV)达98.17%,与杂交狼尾草相近,具有一定的饲用价值。

Abstract: This study was to determine the commercial value and optimum harvest time of the common cordgrass, Spartina alterniflora, collected from the wetland of Min River estuaries in Fujian.The analytical results indicated that the grass' nutritional value peaked between June and September in a year.During this period of time, its crude protein reached 11.54%; calcium, 0.32%; phosphorus, 0.16%; NDF, 58.78%; ADF, 34.47%; ash, 7.93%; and NaCl, 3.35%.Consequently, S.alterniflora was found to be rich and complete in amino acids, and that it could be a potential source as forage.
