    AGE DETERMINATION IN ASIAN ELEPHANTS (Elephas maximus) BY DIFFERENT METHODS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-09) HITHAISHI, V.; Dr. K. V. JAMUNA); Dr. K. V. JAMUNA)
    A study was undertaken for determination of age in Asian elephant (Elephas maximus) by using different methods. Different morphometric measurements of 84 male elephants and 35 female elephants were taken. A total morphometric data of 119 animals belonging to 5 different places were analyzed by multiple regression analysis revealed that age was influenced by parameters like shoulder height and body length in males, right tusk girth was more significantly effecting than left tusk girth, whereas chest girth was more influenced by age in female elephants. Using this data the best fit equation was derived for male and female elephants separately to determine the age Y = - 61.254 + 0.277(H) ** + 0.536(L) ** Where, Y = age in years, H = height, L = length, ** represents that H and L is significant

    STUDY ON GASTROINTESTINAL PARASITES IN LIONS AND EFFICACY OF ANTHELMINTICS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-07) DHAREPPA GANAGER; Dr. G. S. MAMATHA)
    The present study was carried out to know the occurrence of gastrointestinal parasites in lions and to evaluate the anthelmintics efficacy in different locations viz., BBP, Bengaluru (12), SCZG, Mysuru (4) and TLST, Shivamogga (4). In a total of 20 faecal samples examined by direct and concentration methods, 15 samples revealed positive for helminthic infections viz., Ancylostoma spp. (66.6%), Toxocara leonina (60.0%), Spirometra spp. (20%) and protozoan infection of Balantidium coli (13.3%) cysts with an ove

    ULTRASONOGRAPHIC STUDY OF ABDOMINAL ORGANS IN SLOTH BEARS (Melursus ursinus)
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR-585 401, 2018-01) SUMEDH M. SHASTRY; Prof. M. NARAYANA BHAT
    Ultrasonographic study of abdominal organs in 18 sloth bears (Melursus ursinus) was conducted in Wildlife SOS, Bannerghatta Bear Rescue Centre. The sloth bears were anesthetized using ketamine and xylazine for the procedure. The animal was placed on the dorsal recumbency. The ultrasound study of different abdominal organs like the liver, gall bladder, spleen, kidneys and urinary bladder were carried out. The size, shape, thickness and echotexture of different organs were recorded. The lobes of liver were not well distinguished in ultrasound scanning except for caudate lobe. The normal hepatic parenchyma was uniform with fine or coarse granular echogenicity compared to spleen. The gall bladder was a round, oval or pear shaped structure. The wall was thin, smooth and hyperechoic with variable amount of sludge inside the bladder. Spleen was an elongated sock like structure. The spleen was divided into head, body and tail. The spleen was surrounded by a capsule which was found to be hyperechoic. The splenic parenchyma was fine, granular and relatively homogenous and was hyperechoic compared to the liver. Kidneys were paired, elongated and lobulated. Each lobule was surrounded by a capsule which was found to be hyperechoic. Echogenicity of both kidneys were the same. Each lobule consisted of cortex which had very fine and uniform echotexture. Medulla was an anechoic structure. The cortex and medulla were divided by a hyperechoic line. The normal bear urinary bladder was pear shaped. The bladder constituted of urine which was anechoic in nature. The physiological and biochemical parameters were also recorded. The respiration and heart rate were slightly below the normal range. This may have been due to the use of xylazine as anesthesia for sloth bears. The biochemical parameters were in the normal range.

    AGE DETERMINATION IN ASIAN ELEPHANTS (Elephas maximus) BY DIFFERENT METHODS

    A study was undertaken for determination of age in Asian elephant (Elephas maximus) by using different methods. Different morphometric measurements of 84 male elephants and 35 female elephants were taken. A total morphometric data of 119 animals belonging to 5 different places were analyzed by multiple regression analysis revealed that age was influenced by parameters like shoulder height and body length in males, right tusk girth was more significantly effecting than left tusk girth, whereas chest girth was more influenced by age in female elephants. Using this data the best fit equation was derived for male and female elephants separately to determine the age Y = - 61.254 + 0.277(H) ** + 0.536(L) ** Where, Y = age in years, H = height, L = length, ** represents that H and L is significant and Y = -54.615 + 0.720 (CG) ** Where, Y = age in years, CG= chest girth respectively. The morphological observations by visual method were to some extent yielded results which were not accurate and was with lot of variations. Hence visual method yielded only approximate age which could be used for age classes. The most useful methods according to this study was determination of age through dentition that was by lamellar number, stage of molar in progression, length and width of molar teeth and by using age reference line method in the mandibles. The 12 specimens of unknown age were used for the present study. Age Reference Line method could be successfully used in Asian elephants to allocate the age.
