| Abstract: | This study was aimed at elaborating the nutritional value of new varieties of alfalfa(Medicago sativa),and providing nutritional parameters for the adaption of alfalfa in the South of China.Growth properties,general nutrition of alfalfa hay and digestibility on five different growth periods(vegetative stage,bud stage,early flowering,flowering and podding stage) of Yumu No.1 alfalfa were studied.There was a significant influence on the nutrition of alfalfa hay in different periods(P<0.05).The leaf/stem ratio,fresh/dry ratio,crude protein,ether extract,ash and calcium decreased in turn switching from the nutrition stage to the pod-besring period.The whole variation trend is quick-slow-qiuck,characterized as "chair-type".The phosphorous decreased while the content of neutral detergent fiber,acid detergent fiber and acid detergent lignin increased from the nutrition stage to the pod-besring period.The whole trend showed fast-slow-fast anti-chair-type shape.The digestibility of alfalfa hay,digestible energy,crude protein,ether extract,ash,neutral detergent fiber,acid detergent fiber decreased in turn from vegetative stage to podding stage.Nutritional composition and digestibility of early flowering and flowering of Yumu No.1 alfalfa had no significant differences(P>0.05),which was different from the northern alfalfa hay.The nutrition composition digestibility of the alfalfa hay has a positive correlation with the protein content while a negative correlates with the ADL content.The influence of harvest time and variety on digestibility actually resulted from the combined effect of the protein of alfalfa hay and the content of acid detergent fiber. |
