Abstract: The white lipped deer (Cervus salbirostris) is a rare animalwith great economic value，and ecedemic in China． In order to protects， develop and utilize the resources，we study the food habits and reproduction of the white lipped deer.the research was
carried out in 1986 by the Sine-Japanese Team of United survey in Yushu，Goluo Provintures of Qinghai Province and Garze Prefecture of Sichuan Province.Of course the data collected before were used in this paper．
The white lipped deer is a plant eater． According to direct observation and the analysis of two rumina contents of the deer．the plants which the deer feeds belong to 62 among them 24species are most preferable (Table．2)， grasses (Grarmneae) and sedges (Cyperraeeae) are the most important food of the deer． According to the observation， there was a close relationship between the grazing time and the biomaas of the plant communities used． The duration of grazing bouts among stags in daytime was shorter than that among does．More grazing time was spent in the morning，spent lesser at noon and much more time was lying down or ruminate itself, the next grazing peak was in the later afternoon． Tho bite rate of the deer was simi1ar in adult
stags and does (Tab.1)．
In early Sept．mature stags left their usual!ivable range gradually，some of them moved directly to the rutting does and attempt to form their harems． During th rutting season，stages show excited，active and eat almost nothing.In order to monopolize the harems， there were intence competitions or fight ng between muture stags． At last，a haremholding stagwas produced． The others reverted to wander around the harem fat apart over 100m． Mating period lasted about ten days．the body weight and status of harem-holder show a rapid decline，especially in the latest period of rutting．So a new vigorous stag usualIy took it positition. 8 groups of the deers were observed (Tab．3)．
Mating season of white lipped deer is different in dissimilar region,especially in different altitude (Tab．4)．At this stage does also show their interest in the stags，lick and sometimes mount them．When the mating behavior is over，the conceiving does become staider．Gestation period is about 8 months (230-250 days)．The mated does will birth give from the end of May to late June next year．The breed once yeas and the female onlygives birth to one young．After the birth of calves，the mother licks clean the body at once．After halfan hour of the birth，the caLf is usually able to stand． Through 2-3 days，doe commonly leads her calf move slow away the place of birth， reach to the dense shrub or higher grass．The mother grazes or rests within the sight about lOOm far from her calf． If disturbance happen， the calf quickly hides itself，and the mother commonly escapes toward to the opposite direction so as to leave the calf． She attempted to turn away the sight of the enemies．
