In this study, changes of testosterone hormone levels in the blood serume of pre-pubertal Angora goat kids, during the months of May, June, July, and August, were researched. In these months, the testosterone hormone levels were found to be, 41.462.310; 53.611.940; 87.672.410, 205.468.700 ng/dl for the male kids and 2.000.000; 2.000.000; 2.570.172 ve 2.920.259 ng/dl for the female kids respectively, For the female kids, there was not any significant change in the testosterone levels measured during four months. However, the testosterone levels in male kids were found to be significantly increasing (P<0.01) due to the maturing age and consequently the approaching puberty.
