\textbf{Abstract}
\begin{abstract}
\normalsize{
Efficiency of feed conversion, faecal oocyst count and microbial load of broiler chickens fed supplements of three phytogenic plants were evaluated. A total of four hundred and eighty 1 day"=old Arbor Acre chicks were divided randomly into six treatments and four replicates. Fresh leaves of the plants were harvested, washed, dried and milled. The milled leaves were included to the basal diet as follows; Treatment 1 was a negative control (containing no antibiotic nor phytogenic plant) while treatment 2 served as the positive control (containing Neoceryl). Diet 3 contained \unitfrac[5]{g}{kg} \textit{Azadirachta indica} leaf meal. The birds in treatment 4 were given diets that contained \unitfrac[2.5]{g}{kg} each of \textit{Azadirachta indica} and Spondias mombin leaf meals. Diet 5 contained \unitfrac[2.5]{g}{kg} each of \textit{Azadirachta indica} and \textit{Chromolaena odorata} leaf meals, while those in treatment 6 received diets containing the three test ingredients at \unitfrac[1.7]{g}{kg} each. Data obtained on growth performance and microbial load were analysed using one"=way ANOVA (SAS, 1999) and significant means were separated using Duncan's Multiple Range Test at $p < 0.05$. At day 56, significant differences ($p < 0.05$) were observed across the treatments for final weight, daily feed intake, daily weight gain and feed conversion ratio. Total bacteria count in excreta was highest in T2 and lowest in T1 and T3 at the end of the starter phase and finisher phases. Birds on diet 3 had the highest mean value for total bacteria count in the rectal swab while birds on diet 1 recorded the lowest. T6 had the highest mean value for total bacteria count in the small intestine while T3 had the lowest mean value. Birds fed diets containing \textit{Azadirachta indica} had a value of 4200 opg count. Oocyst was not present in birds fed diet 4. This study concluded that \unitfrac[2.5]{g}{kg} \textit{Azadirachta indica} and Spondias mombin improved FCR, reduced faecal oocyst count and microbial load of broiler chickens.}
