摘　　要：理毛行为(Grooming behavior)的定义是动物个体对自身或其同类个体体表(皮肤、毛发或羽毛等)进行的多种形式护理,包括对体表进行有规律的梳理,以及用舌头或嘴唇舔皮肤和毛发等(Vea et al., 1999 )。在灵长类动物中,理毛行为大多表现为个体接触和探查自身或另一个体体表被毛,将毛发分开后从中拣出盐粒或皮肤寄生物放入口中咀嚼或直接用嘴咬食被毛下的盐粒或皮肤寄生物(李银华和李保国,2002)。Grooming behavior is one of the social behaviors commonly found among primates. Such behavior is often associated with particle removal, with the groomers manually brushing away,or sometimes devouring, loose particles. However, the function of allogrooming and the associated particulate matter still remain controversial. In this study, we used all occurrence sampling to record autogrooming and allogrooming behaviors in captive Sichuan snub-nosed monkey(Rhinopithecus roxellana) in the Endangered Animal Breeding Center of the Beijing Wildlife Park from February to Match 2017. A total of 120 bouts of autogrooming and 259 bouts of allogrooming were recorded to test the hygienic functional hypothesis and the compensation hypothesis of allogrooming. The particulate matter on the hair and skin was checked for ectoparasite, flakes of skin or secretion of salt using microscopy. In addition, we manipulate salt and protein intake via offering the monkeys with drinking water of different concentrations of salts and fresh Populus leaves with high protein, in order to test the nutritional function of allogrooming and particle intake. Our results suggested that the grooming behaviors of the monkeys in general were consistent with the prediction of hygienic functional hypothesis, but in adult males,but not in adult females, were broadly in line with the prediction of compensation hypothesis. No association was noted between grooming and removal of parasites, and neither the functions of obtaining protein, or sodium chloride were confirmed. In conclusion, grooming behavior of captive Sichuan snub-nosed monkeys is more likely to be a semi-ritualized social behavior.
