Free testosterone level and quality of cauda epididymis sperm of local rabbit that given commercial feed supplemented by cod fish liver oil

This study was intended to determine the free testosterone levels and sperm quality of local rabbit that was given commercial feed supplemented cod fish liver oil.  The experiment design that was used in this research was Complete Random Design (CRD) with four experiments of feed, i.e. commercial feed without cod fish liver oil (R-0) as control, commercial feed + 1,5% cod fish liver oil (R-1), commercial feed + cod fish liver oil 3% (R-2), commercial feed + cod fish liver oil 4,5% (R-3). Each experiment included eight rabbits and feed experiment was given starting by 13 weeks to 26 weeks years old. The variable that observed was free testosterone level and sperm quality of local rabbit. The data that was obtained to be analyzed with One Way ANOVA and if its contrast was done more test with Duncan’s Multiple Range Test (DMRT). The result of this research was to show that supplementation of cod fish liver oil in the commercial feed was to show the result that a real distinction of (P<0, 05) towards free testosterone level and sperm quality of local rabbit
