Indeks Massa Tubuh dan Morfometri Monyet Ekor Panjang (Macaca facicularis) di Bali

Abstract

A study to determine the body mass index and the morphometry of wild long-tailed macaques was carried out in Sangeh, Aka Wton, Ubud, Pulaki and Bukit Gumang. The macaques were anaesthetized intramuscularly with combined ketamine and xylasine using blow pipe or pistol. The body weight and the length of crown-mp, tail, upper arm, fore arm, thigh and leg, were measured under anaesthetized conditions. The body mass index was calculated by dividing the body weights with crown rump length (kg/m2).T he result showed that male macaques weighed almost 1.5 times heavier than those of female macaques. The body mass index of male macaques of Bukit Gummg is the smallest. Meanwhile, the sizes of female macaques were more relatively uniform than those of male macaques. Moreover, distinction among female groups can be made by determination upper and fore arm length, thigh length, and leg length. Key words: long tailed macaques (Macaca fasckularis), body mass index, morphometry
