Abstract
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
