Post-natal growth in live mass and in body dimensions with age is descriptionbed in a captive herd of eland Taurotragus oryx, using the von Bertalanffy growth equations. Asymptotic live mass of males (575 kg) was 45% higher than the value for females (316 kg). Asymptotic body dimensions were also higher in males, girth by 27%, height at withers by 13% and body length by 9%, these data illustrating the sexually dimorphic nature of growth in eland. In winter, body growth rates were significantly lower than in the summer, but these variations are not apparent from theoretical von Bertalanffy growth curves. A combination of linear measurements is descriptionbed for the prediction of live mass.
