AB  - &lt;p&gt;&lt;em&gt;A 28-day feeding trial study was conducted to evaluate the effect of Bacillus subtilis (probiotics) supplementation &lt;/em&gt;&lt;em&gt;on the growth performance of finisher broiler chickens. One hundred and twenty (120), three (3) weeks old mixed &lt;/em&gt;&lt;em&gt;sexes chicks were used in this study. The birds were randomly assigned to four dietary treatment groups; T&lt;/em&gt;&lt;em&gt;1&lt;/em&gt;&lt;em&gt;, T&lt;/em&gt;&lt;em&gt;2&lt;/em&gt;&lt;em&gt;, &lt;/em&gt;&lt;em&gt;T&lt;/em&gt;&lt;em&gt;3&lt;/em&gt;&lt;em&gt;, and T&lt;/em&gt;&lt;em&gt;4 &lt;/em&gt;&lt;em&gt;with Bacillus subtilis supplementation at 0ml/litre, 10ml/litre, 20ml/litre and 30ml/litre in drinking &lt;/em&gt;&lt;em&gt;water respectively. The treatment groups were replicated three times with ten (10) birds per replicate in a &lt;/em&gt;&lt;em&gt;Complete Randomized Design. The birds were housed in deep litter pens and all necessary routine management &lt;/em&gt;&lt;em&gt;practices were observed. The growth performance data were collected for parameters such as initial weight, final &lt;/em&gt;&lt;em&gt;weight, weight gain, feed intake and feed conversion ratio (FCR). The data collected were statistically analysed &lt;/em&gt;&lt;em&gt;using one-way analysis of variance (ANOVA) with SPSS version 16.0 and significance of differences among &lt;/em&gt;&lt;em&gt;treatments was determined using Duncan multiple range test. There were no significant differences (P&amp;gt;0.05) &lt;/em&gt;&lt;em&gt;across the treatment groups for Initial weight. However, significant (P&amp;lt;0.05) differences were observed for feed &lt;/em&gt;&lt;em&gt;intake, final body weights and feed conversion ratio (FCR). Therefore, supplementation of broiler finisher diet &lt;/em&gt;&lt;em&gt;with 20ml/litre in drinking water is recommended for optimal performance&lt;/em&gt;&lt;/p&gt;
