Effect of cod liver oil supplementation in commercial feed on reproductive organs weight and ovarian follicles size of local rabbits

This study aimed to determine the effect of cod liver oil supplementation in commercial feed on reproductive organs weight and ovarian follicles size of local rabbits. The experimental design used was Completely Randomized Design with four feed treatments, i.e. commercial feed without supplementation of cod liver oil (CLO) as control (P0), commercial feed supplemented by 3% CLO (P1), 4.5% CLO (P2), and 6% CLO (P3). Each treatment consisted of ten rabbits as replication and treatment were given to rabbits from aged 4 to 6 months. The parameters observed were the weight of the reproductive organs, namely the ovaries, fallopian tubes, uterus and the size of the ovarian follicles, namely primary, secondary, tertiary and preovulatory follicles of local rabbits. The results showed that various levels of cod liver oil supplementation in commercial feed differed significantly (Pl0.05) to the weight of the reproductive organs and the size of the ovarian follicles of local rabbits. It can be concluded that cod liver oil supplementation at 4.5% level in commercial feed capable increase the reproductive organs weight and ovarian follicles size of local rabbits.
