| Abstract | Introduction The Sumatran rhinoceros (Dicerorhinus sumatrensisi, with a population of less than 400 in the world, is the most critically endangered of all the five existing rhino species. Its distribution that used to range from northern India to Borneo is now fragmentarily found in Sumatra, Peninsula Malaysia, and Sabah. In other parts of South-EastAsia, such as Sarawak., Thailand, Myanmar, and Laos, their existence has yet to be confirmed and the viability of any population is unlikely. Poaching for horns, habitat degradation for timber and land conversion into agriculture, industries and other human uses are major threats to these rhinos (WWF, 1996). Worldwide, captive breeding for over a hundred years has yet to produce a progeny. Aggressive courtship behaviour may be the major factor for difficult breeding in Sumatran rhinos. Such occasion usually occurs due to untimely introduction of the male to a female that is not in oestrus (Zainal-Zahari et al., 1995). In order to determine oestrus, various methods including plasma hormonal assay (Zainal-Zahari et al., 1995), excretory metabolites assay (Heistermann et al., 1998; Wasser et al., 1996; Schwarzenberger et al., 1993; Hindle et al., 1992) and ultrasonography (Schaffer, et al., 1994) have been deployed. These methods may although proved to be effective, are usually costly, tedious and require professional handling. Thus, vaginal cytology, a fast, inexpensive and an easy method that had been proven effective in dogs (Wright et al., 1990; England, 1992), sheep (Zourgui et al., 1976), Yucatan pigs (Rodgers et al., 1993) silver foxes, Vulpes vulpes (Boue et al., 2(00) was employed on Sumatran rhinoceros to test for its applicability in detecting oestrus in this species. |
