%X In this study, the contents of 8 nutrients(CP,NDF,ADF,IVDDM,Ca,P,Na,K)were measured for the twigs and leaves of 14 browse species, sedges,forbs,ferns and the bark of Ulmus spp.,collected in the southern Xiao Xingan Mountains,northeastern China,from 1991 to 1992.The results show that there was a significant difference in the content of those 8 nutrients for each forage item(P<0.05).The seasonal content of crude protein was highest and lowest in the leaves and the twigs of browses,respectively.The seasonal content of neutral and acid detergent fiber(NDF and ADF)reached highest in the browse twigs, and decreased to the lowest level in forbs.The seasonal content of calcium was highest in the browse twigs and forbs,and lowest in the sedges.For the potassium,it was highest in the forbs and ferns,and lowest in the browse twigs.The seasonal content of phophorus and sodium changed greatly,and showed no consistant patterns in each forage item.The content of crude protein showed alittle seasonal variation in the browse twigs,but it decreased continuously in the browse leaves,sedges,forbs and ferns,from spring to autumn.Each forage item had lower content of NDF and ADF in spring than in other seasons.There was a decreasing trend in the content of potassium while different seasonal pattern of change existed in the content of calcium, potassium and sodium for each forage item from spring to winter.The in vitro digestible dry matter was positively and negatively related to the content of crude protein and ADF,respectively.
