ABSTRACT

Asian elephant, Elephas maximus is placed in Schedule I and Part I of Indian Wildlife Protection Act (1972) conferring it the highest level of protection. In higher mammals like elephants, reproductive success exclusively depends on odour produced from female during oestrus phase and response made by the male before mating. The odours released by the females qualitatively vary with the reproductive state namely during pre-oestrous, oestrous and post-oestrus periods. The present study aimed to identify and compare the volatile profiles of urine samples of male and female Asiatic elephants in captivity. From our assay it was found that peculiar pheromonal carrying compounds namely p-Cresol, 9-Octadecenal, 9-Hexadecenal, 13-Octadecenal and 6-Octadecenoic acid were present only in female urine sample when compared with the male urine sample. In SDS-PAGE analysis, it was confirmed that the protein with low molecular weight protein below 20 kilo daltons has been found and it depict that these are the compounds which act as pheromone carrying lipoproteins.
