The objectives of this study were to investigate different levels of multi-enzymes (polzyme®) liquid on the growth performance, carcass & relative organ weights and meat quality in broiler chicken. The study lasted 32 days and took place at Hajee Mohammad Danesh Science and Technology University April 2024. A total of 120 mixed-sex broiler chicks (Arbor acres), aged 7 days, were randomly assigned into four treatment groups (T0, T1, T2, and T3,) with each group consisting of three replicates, and each replicate containing 10 chicks. Four supplemental levels of multi-enzymes (polzyme®) liquid were added in to their drinking water. T0 was designated as control group, receiving solely commercial feed and tap water without (polzyme®) whereas T1, T2, and T3 were donated the commercial feed and tap water supplemented with 0.5, 1 and 1.5 ml / L of (polzyme®) liquid respectively. The current findings indicate that the of the addition of 0.5 ml / L multi-enzymes (polzyme®) to broiler’s drinking water enhanced (p˂0.05) their weight at 28 days of age and their final body weight and overall feed intake but did not have any effect of feed conversion ratio (FCR). Furthermore, polzyme® supplementation at 0.5 ml/L of Polzyme® in broiler drinking water showed significant influence (p˂0.05) on relative organ’s weights (breast, thigh, head, gizzard and intestine). However, supplementation at 1.5 ml/L Polzyme® in broiler drinking water showed significant influence (p˂0.05) on cooking loss value of broiler breast, but not dripping loss. Therefore, it can be concluded that adding 0.5 ml/L of commercial multi-enzyme (Polzyme®liquid) to broiler drinking water had the best values for increasing growth performance, overall feed intake, carcass yield percentage (%), carcass weight, and relative organ weights between treatment groups. It also produced economic benefits.
