Morphometric Based Estimation of Timor Deer Body Weight

Abstract

This study aimed to develop a method for estimating the body weight of Timor deer based on morphometric measurements in captivity to facilitate monitoring without direct weighing. The research was conducted from August to September 2025 at the Jatilengger Deer Breeding Center, Blitar Regency. The animals observed consisted of 25 adult males and 22 adult females in good health. Body measurements included chest girth, body length, and body height, while actual body weight was recorded using a digital scale. The data were analyzed using multiple linear regression and compared with several empirical estimation formulas to identify the most accurate model. The results showed a strong correlation between body measurements and actual body weight in both sexes. The multiple linear regression model provided the highest level of accuracy and consistency in estimating body weight compared to empirical formulas. These findings indicate that morphometric parameters can effectively be used as predictors for body weight estimation in Timor deer. The developed model is expected to assist deer breeding centers in monitoring animal growth, evaluating nutritional status, and improving management efficiency without requiring direct weighing.
