Body morphometric traits may serve as practical indicators for selecting dairy goats. This study aimed to evaluate the relationships among body morphometry, udder volume, and milk production in Ettawa Crossbreed goats in Nusa Tenggara Barat, Indonesia. Twenty-five lactating does were evaluated for body length, body height, chest circumference, udder volume, and milk production using correlation and regression analyses. Mean measurements were 72.76 cm, 66.60 cm, 73.24 cm, 30.31 cm3, and 327.76 mL/day, respectively. Body morphometric traits were positively and significantly correlated with udder volume (r = 0.60–0.70; p ≤ 0.01) and milk production (r = 0.45–0.56; p ≤ 0.05). However, the correlation between udder volume and milk production was weak and not statistically significant (r = 0.33; p = 0.108). These findings suggest that body morphometry may support selection for udder development, whereas udder volume alone is not a reliable predictor of milk production.
