AB  - &lt;p&gt;&lt;em&gt;This study evaluated the growth performance and economy of feed conversion of broiler chicken orally&lt;/em&gt;&lt;em&gt;administered Aloe vera and Vernonia amygdalina leaf extracts as phytomedicines. Using a completely randomized &lt;/em&gt;&lt;em&gt;design (CRD) model, a total of 120 one-day-old Ross 308 broiler chicks were randomly assigned to four &lt;/em&gt;&lt;em&gt;treatments. with three replicates having ten birds per replicate thus: T1 (control, vaccinated against Gumboro &lt;/em&gt;&lt;em&gt;disease at the 1&lt;/em&gt;&lt;em&gt;st&lt;/em&gt;&lt;em&gt; and 3&lt;/em&gt;&lt;em&gt;rd&lt;/em&gt;&lt;em&gt; week of the experiment and against Newcastle disease at the 2&lt;/em&gt;&lt;em&gt;nd&lt;/em&gt;&lt;em&gt; and 4&lt;/em&gt;&lt;em&gt;th&lt;/em&gt;&lt;em&gt; week of the &lt;/em&gt;&lt;em&gt;experiment); T2 (administered 100 g Aloe vera/4 litres of water); T3 (administered 100 g Aloe vera + 50 g &lt;/em&gt;&lt;em&gt;Vernonia amygdalina/4 litres of water); and T4 (administered 100 g Aloe vera + 100 g Vernonia amygdalina/4 &lt;/em&gt;&lt;em&gt;litres of water). The extracts were administered over four consecutive days per week followed by three days resting &lt;/em&gt;&lt;em&gt;period, for five weeks. All groups were fed the same diet (single phase formulated diet) for eight weeks. Data &lt;/em&gt;&lt;em&gt;collected for growth performance and economy of feed conversion were analysed using the SPSS statistical &lt;/em&gt;&lt;em&gt;package (version 23, 2021). Results showed that although there were no significant differences (P&amp;gt;0.05) in growth &lt;/em&gt;&lt;em&gt;performance across the treatments during the starter and finisher phases, T2 (100 g Aloe vera/4 litres of water) &lt;/em&gt;&lt;em&gt;consistently showed better weight gain and lower FCR, indicating superior growth performance. In conclusion, &lt;/em&gt;&lt;em&gt;Aloe vera and Vernonia amygdalina extracts did not negatively affect broiler growth performance, and T2 &lt;/em&gt;&lt;em&gt;emerged as the optimal treatment, offering the best balance between growth performance and economic efficiency&lt;/em&gt;&lt;/p&gt;
