Résumé
The experiment was conducted from Nov.2005 to Nov.2006.During the study, biomass and nutrition of grassland、liveweight of grazing sheep and goat were measured. By analyzing the relation of the dynamic of plant biomass and nutrition to the change in liveweight of grazing sheep and goat, acquired results showed as following:1、Plant biomass was minimum in middle of May 2005 and was maximum in middle of Sep.. The results suggested that the dynamic of plant biomass liked single kurtosis.2、Nutritional content was different during different months. There is best nutritional value in summer, worse in autumn and worst in winter and spring.3、Compared with adult goat and sheep ,lamb and kid had more net year liveweight increases ; Compared with sheep, goat had more net year liveweight increases.4、With the dynamic of plant biomass, the liveweight of grazing sheep and goat showed variation .There were significant correlations between plant biomass and liveweight of grazing sheep and goat.5、With the dynamic of nutritional content, the liveweight of grazing sheep and goat also changed . There were correlations between nutritional content and liveweight of grazing sheep and goat.6、Compared with nutritional content, the liveweight of grazing sheep and goat was more affected by plant biomass

Mots clés : Plant biomass Nutritional content The live weight of grazing sheep and goat
