Abstract:	The effects of graded levels of dietary Tridax procumbens (T. procumbens) on semen qualities and morphologies in the rabbit buck were investigated using a completely randomized design. Forty-eight (48) growing rabbit bucks of 16 to 18 weeks of age and weighing 1260 -1305 grams were used in the investigation. The rabbit bucks were randomly assigned to four dietary treatments of rabbits (12) per treatment and 4 replicates of 3 rabbits/replicate. The four treatments contained all nutrients at similar concentrations, except varied levels of dietary T. procumbens contents as: T1 (negative control) contained 0g of the test ingredient, that is, T. procumbens. T2, contained 200g of T. procumbens, T3, contained 300g of T. procumbens and T4, contained 400g of T. procumbens/kg of feed respectively.The rabbit bucktreatment groups received their respective diets for two months (8 weeks). Semen were collected from the bucks by teasing them with a doeusing artificial vagina.Each ejaculate was evaluated for pH, volume, motility, viability and morphology. There were no differences (P > 0.05) amongst treatments in semen pH. However, semenvolume, motility, viability and normal morphologies of rabbits increased linearly (P
