Alpine musk deer (Moschus sifanicus.) are endangered due to illegal hunting and habitat degradation. Musk deer farming may be an important way to conserve musk deer populations and as a method for the sustainable utilization of musk deer resources, but no studies have been conducted on the stereotypic behavioral of captive musk deer. From June 2008 to January 2009, the stereotypic behavior of captive alpine musk deer was studied at Xinglongshan Musk Deer Farm (XMDF) located in Xinglongshan National Nature Reserve, Gansu Province. A total of 54 musk deer were studied. Focal sampling was used to observe and record the frequencies of stereotypic behaviors (e.g.galloping or to-fro-walking). Stereotypic behavioral differences between specified enclosure populations were explored according to variables such as Range, Age, Age classes, Gender and Reproduction costs. The results showed captive alpine musk deer in XMDF developed and expressed abundant locomotor and oral stereotypic behaviors ((0.084±0.025) times, n=54), as a result of stable, artificial concentrate-food provisions. The relatively narrow enclosure area had a direct effect on the development of stereotypic behavior, withindividuals enclosed in smaller spaces expressing stereotypic behavior more frequently than those in larger areas (P<0.05). The intensity of stereotypic behavior in females ((0.07±0.03) times, n=31) was significantly lower than that of males ((0.11±0.04) times, n=23) owing to the former's lactation experience (P<0.05), and captive bred musk deer ((0.10±0.06) times, n=15) were inclined to demonstrate stereotypic behavior more frequently than those captured from the wild ((0.07±0.02) times, n=30) due to differences in experience, the difference, however, was not significant (P>0.05). No significant difference in duration of behavior was found between months, but musk deer expressed stereotypic behaviors more often during mating season ((0.140±0.05) times, n=32) than non-mating season ((0.037±0.017) times, n=47). Moreover, the stereotypic behaviors expressed by sexually inactive females ((0.17±0.12) times, n=10) was significantly more frequent than sexually active females ((0.05±0.02) times, n=15) (P<0.05), correspondingly, sexually inactive male musk deer expressed stereotypic behavior ((0.10±0.04) times, n=13) more frequently than sexually active males((0.06±0.02) times, n=9),the difference being insignificant (P >0.05).
