This study was conducted using spent coffee grounds in concentrated diets as a defaunating agent. Defaunation was performed by supplementing spent coffee grounds as follows: T1 (Control) — Napier Grass + Concentrates (at 1.0% of body weight); T2 —Napier Grass + Concentrates (at 0.75% of body weight) + Spent Coffee Grounds (at 0.25% of body weight); T3 — Napier Grass + Concentrates (at 0.50% of body weight) + Spent Coffee Grounds (at 0.50% of body weight); and T4 — Napier Grass + Concentrates (at 0.25% of body weight) + Spent Coffee Grounds (at 0.75% of body weight). The experiment was set up in a Completely Randomized Design (CRD). Rumen fluid was collected in each animal through stomach tubing before and after the experiment for bacterial and protozoal counting. Results revealed that spent coffee grounds (P<0.001) is effective in reducing protozoal numbers and increasing the bacterial population in all levels and frequencies as compared to the control. However, T4 appeared to be the best treatment in reducing protozoal numbers with a corresponding greater increase in bacterial counts. Therefore, spent coffee grounds can effectively manipulate the rumen environment by reducing the protozoa without negative effects on bacteria.
