The present study aimed to evaluate the additive effect of beeswax on production performance, carcass characteristics, and some biochemical parameters in broiler chickens<strong>.</strong></p> <p><strong>Materials and methods:</strong> A total of 192 Cobb 500 chicks aged 7 days and weighing an average of 76.57±1.24 g were used and divided into 4 groups: a control group (L0) receiving a basic diet and three experimental groups randomly receiving a basic diet supplemented with 0.25% (L1), 0.50% (L2), and 0.75% (L3) beeswax powder.</p> <p><strong>Results:</strong> The results of this study revealed that incorporating beeswax into the broiler chicken diet significantly improved (p˂0.05) certain growth parameters (average daily gain and feed conversion ratio). Specifically, 0.25% supplementation (L1) led to a significant improvement in the average daily gain (3%), the average feed conversion ratio (16.17%), and mortality rate (50%). A significant decrease (p &lt; 0.05) in feed intake (FI) was observed during the finishing phase (weeks 4–5) for groups L2 and L3. An inclusion rate of 0.25% of beeswax offers the best balance, improving growth performance while reducing feed costs.</p> <p><strong>Conclusion:</strong> Beeswax shows potential as a beneficial feed additive, offering a natural alternative for use in poultry feed.</p> <p><strong> </strong><strong>Keywords</strong><strong>:</strong> Bee products, feed supplement, growth performance, poultry</p> Hippolyte MEKUIKO WATSOP, Lydie MAIDJAKBA, Mama MOUCHILI, François DJITIE KOUATCHO, Jules LEMOUFOUET, Danut Nicolae ENEA, Aoudou YAOUBA Copyright (c) 2026 Journal of Experimental and Applied Tropical Biology https://creativecommons.org/licenses/by-nc/4.0 https://www.journal.jeatb.com/index.php/1/article/view/67 Sat, 25 Jul 2026 00:00:00 +0000
