Determination of Endogenous Faecal Glucocorticoid Metabolites to Evaluate Stress Response in Wild Pigs Interfering with Agriculture Adjoining Forest Regions in Correlation with Conflict and Meteorological Factors - A Non Invasive Approach

Boon Allwin, Jayathangaraj MG, Palanivelrajan M, Raman M

The study was carried out to assess the faecal cortisol concentration in wild pigs entering the agricultural fields around the forest and in domestic pigs comprising of desi pigs and cross bred pigs, in order to arrive at the baseline values pointing to stress factors. The adjoining areas of Mudumalai wildlife region, Sathyamangalam wildlife region and Anamalai wildlife region of Tamil Nadu, India were included in this study programme. The documentation of the quantifiable meteorological factors in the identified conflict areas was done. The mean faecal cortisol concentration in the case of wild pigs that entered in the agricultural fields adjoining the Mudumalai wildlife region, Sathyamangalam and Anamalai region were found using ELISA (Enzyme Linked Immuno Sorbent Assay). The mean faecal cortisol concentration of desi pigs as well as cross bred pigs was also documented to be used as primary and secondary control values. The occurrences of conflict were also classified as low, medium and high based on the intensity. Suitable management related measures were recommended pertaining to the findings observed in this study like increased mean faecal cortisol concentration in wild pigs, comparative wild pig- human conflicts pertaining to the variations in the meteorological factors of the areas were studied. The findings demonstrated that fecal glucocorticoid assays provide an index of physiological stress in wild pigs and may prove useful in addressing conservation and conflict issues.
