Abstract

Abstract: The dynamic changes of nutrients content in 3 kinds of forage ramie were preliminarily studied and the nutritional value of the feeding Ramie was evaluated by the grey correlation degree method. The results showed that the content of crude protein and crude fat of 3 kinds of forage ramie was decreased-ascending-decreasing with the harvest stubble. The content of total phosphorus in 3 kinds of forage ramie and HR001 crude ash showed ascending-descending-ascending trend. The content of crude ash in HR002 and Zhongzhu No.2 showed a downward-rise-decline-rise trend. The CA content of 3 kinds of ramie and the content of HR001 and HR002 crude fiber showed a rise-decline-rise-decline trend with the number of harvesting stubble. The weights of 6 evaluation indexes were：crude protein,crude ash,crude fiber,calcium,phosphorus and coarse fat. Using the grey correlation degree to evaluate the nutritive value of the forage ramie,the overall performance of ramie HR002 was the best,the ramie HR001 was the second,and the Zhongzhu No.2 was the worst.

Key words: ramie（Boehmeria nivea L.）, nutrient, dynamic change, grey relational degree
