Organ, Testicular and Epididymal Morphometrics of Male Rabbits fed Dietary Cerium Oxide
32 growing buck rabbits of about 12 weeks old were used to assess the effects of inclusion of different dietary concentrations of Cerium oxide (CeO), a Rare Earth Element, at 0, 50, 100, 150mg on organ and relative organ weights, testes and epididymal morphometrics of the animals. The animals were randomly allotted to the four dietary groups, with eight animals per group. The weights, lengths and widths of reproductive organs, other body organs (like liver, kidney, spleen, heart, adrenal gland, pancreas, lung and gastro-intestinal tract) were determined. The results showed no significant (P<0.05) influence of dietary cerium oxide on organs weights (except for relative liver and kidney weights) and the testicular volume but the testicular and the epididymal weights and lengths were significantly (P>0.05) influenced by dietary cerium oxide especially at 50 mg level of cerium oxide inclusion.
