    EFFECTS OF ENVIRONMENTAL ENRICHMENT ON BEHAVIOURAL WELFARE AND FAECAL CORTISOL METABOLITE LEVELS IN CAPTIVE LION-TAILED MACAQUES (Macaca silenus)
    (2021) MOULIDHARAN M; TANUVAS; Prathipa A; Vijayarani K; Palanivelrajan M; Sridhar K
    This study was carried out at Arignar Anna Zoological Park, Vandalur, Chennai, Tamil Nadu with the main objective to study the effect of environmental enrichment on behavioural pattern of captive lion-tailed macaques (LTMs) based on ethogram and faecal cortisol metabolite levels. A systematic ethogram was designed and general behaviour of the LTMs (total=18) from three different enclosures (six LTMs per enclosure) were assessed. The general behaviours were grouped into behavioural states and behavioural events. The behavioural states and events were categorized into normal self-directed, normal social interaction, abnormal self-directed and abnormal social- interaction. Based on the activity pattern of the LTMs, the behavioural states were further categorized into self-directed active, self-directed resting, social, abnormal behaviour and out of sight. In the normal self-directed state, the LTMs spent maximum time sitting and minimum time lying down. Similarly, in the normal social interaction state, the LTMs spent maximum time in allogroom and minimum time wrestling. Self-oral was the only abnormal behavioural state observed. Based on the activity pattern of the behavioural states recorded, it was found that the LTMs spent maximum time in self-directed active state and minimum time in abnormal behavioural state. The behavioural event with high frequency recorded was scan, whereas less frequency were recorded in hide and peek, scream, threat leap and regurgitate and reingest.

    EVOLVING HEALTH INDICATORS TO ASSESS WELFARE STATUS OF CAPTIVE ASIAN ELEPHANTS
    (TANUVAS, CHENNAI, 2021) VEERASELVAM M.; TANUVAS; SELVARAJ P.; SENTHILKUMAR T.M.A.; SENTHILKUMAR S.; SENTHILKUMAR A.
    Protecting and conserving the elephants had acquired the highest ever priority now, due to their dwindling populations. For improving the welfare and management of captive elephants, health and welfare indicators are needed. The study on ‘Evolving health indicators to assess welfare status of captive elephants’ was undertaken to identify and evolve welfare indicators. Indicators were evolved to assess the health and welfare of captive elephants through measurements of a range of physical (body condition score, physical parameters, foot health and disease profile), physiological (stress parameter-cortisol and cardiac biomarkers) and behavioural indicators (housing, feeding and environmental factors). The study population consisted of 46 female captive elephants, which included 24 temple elephants and 22 privately maintained elephants. As a physical indicator. Body Condition Score (BCS)of the elephants were scored in the range of 1 to 5 based on evaluation often regions of the body with various criteria for each body regions. In this 1 to 5 score index, BCS = 1-2 equated to “underweight/thin”, BCS = 3 assigned to “Ideal/normal” and BCS = 4-5 was assigned to “overweight/ obese”. Most of the animals in this study attained BCS =3, followed by BCS = 4. Health profiling included assessments of haematology, serum biochemistry, serum electrolytes, and blood gas and acid base values. Elephants were screened for their heavy metal and trace element status. No significant changes were observed in these values among the elephants. The normal range of these parameters observed in this study indicated the wellbeing and good health of these captive elephants. These values from the larger sample size of 46 elephants could well serve as regional reference range for the assessment of captive elephants.

    MOLECULAR SPECIES IDENTIFICATION OF SNAKES USING ECDYSED SKIN
    (2018) Pattanayak, Deeptimayee; Senthilkumar, K; Vijayarani, K; Senthilkumar, A; Sreekumar, C; TANUVAS
    A study was carried out to identify the species in captive snake species through molecular species identification using ecdysed skin and also to design a universal primer which can amplify the cyt b fragment of all snake species. The samples were collected from Arignar Anna Zoological Park (AAZP) Vandalur, Chennai, and Nadan Kanan Zoological Park, Bhubaneswar and Chennai Snake Park Trust, Guindy. The moulted skins were collected from Rat snake, Indian cobra, Indian Rock Python and Reticulated Python between October, 2017 and March, 2018. The skin samples were collected from individual enclosure and stored in a zip lock cover. During sample collection, the molted skins were characterized by various morphological characters and physical properties through direct observation. Morphological characteristics and physical properties revealed that most of the blackish brown skins were found in Reticulated python (73.33%) and in Indian Rock python (60.00%). The skin colour of pale white was mostly found in case of Rat snake (80.00%) and Indian cobra (53.33%). The statistical analysis revealed highly significant variations (P<0.01) among the the ecdysed skin colour of snake and the species of snake. The skin samples were sheded as fragment casts in case of Reticulated python and Indian Rock python (100%) and in case of Rat snake and Indian cobra the snake the skin were molted as both fragmented pieces and single casts also. The statistical analysis showed that Indian cobra and Rat snake frequently molted the skin as a single piece but in case of Pythons skin was never found as a single piece however sheded as a fragments of skin.

    IDENTIFICATION OF SPECIES AND SEX IN TIGER (Panthera tigris) AND LION (Panthera Leo) THROUGH MOLECULAR SCATOLOGY
    (TANUVAS, 2016) Sharmila, B; Senthilkumar, K; TANUVAS; Jayathangaraj, MG; Karthickeyan, SMK
    A study was carried out to identify species and sex in tiger and lion through molecular scatology techniques and also to develop DNA Barcode for captive tigers and lions present at Arignar Anna Zoological Park (AAZP) Vandalur, Chennai. The scat samples were collected from 29 tigers (11 males and 18 females) and 18 lions (male 7 and female = 11). During sample collection the scat samples were characterized by various morphological characters and physical properties.

    (TANUVAS, 2016) Bashir, Sofiumer; Jayathangaraj, MG; TANUVAS; Senthilkumar, K; Karthickeyan, SMK
    Leopard (Panthem pardus) is the most widely distributed species of wild cats in the World and it is the most common Wild carnivore involved in man- animal conflicts necessitating the identification and monitoring of problematic species. Molecular scatology is a relatively new approach with great potential for species identification and monitoring of animals in conflict zones at DNA level.
