Abstract This study aimed to evaluate the effects of Bay laurel leaf extract conjugated with zinc nanoparticles (Zn-Nano-BLLE) as a growth enhancer and antibiotic alternative in broiler diets on performance, carcass characteristics, blood markers. In completely randomized design, 264 one-day-old Ross 308 chicks were divided into four experimental groups assess impact Zn-Nano-BLLE supplementation. Each group consisted six replicates, each containing 11 unsexed chicks. The treatments follows: control (basal diet) without any additives, three receiving at 1, 2, 3 cm³ Zn-Nano-BLLE/kg feed, respectively. Results indicated that supplementation 1 or cm³/kg feed led significant improvements live body weight gain. lowest intake conversion ratio observed broilers supplemented (30.94 1.14, respectively). However, highest dressing, carcass, heart percentages found group. Additionally, fed showed levels total protein, albumin, globulin, while also exhibiting cholesterol low-density lipoprotein (161.52 88.35, immunoglobulin G (IgG) elevated groups, although no noted M (IgM). Birds given 2 demonstrated superoxide dismutase activity (164 U/ml), had levels. conclusion, dietary inclusion Zn-Nano-BLLE, particularly cm³/kg, enhanced immunity, productivity, antioxidant status, indicates its effectiveness natural production.
