Abstract: The overuse of antibiotic growth promoters (AGPs) in poultry production has raised significant public health concerns, leading to a global push toward safer, natural alternatives. This study aimed to evaluate the efficacy of ORIGORAN, a phytogenic-based feed additive developed by Rivansh Animal Nutrition Pvt Ltd, as a sustainable substitute for traditional AGPs and probiotics in broiler chicken diets. A 42-day feeding trial was conducted using 240 day-old commercial broiler chicks,randomly assigned into four dietary treatment groups:T1 (Control – Basal diet),T2 (Basal diet + Antibiotic growth promoter),T3 (Basal diet + Probiotic),and T4 (Basal diet + ORIGORAN at 500 gm/ton feed).Growth performance parameters, including body weight gain, feed intake, and feed conversion ratio (FCR), were recorded weekly. Haematological,biochemical, and carcass quality parameters were assessed at the end of the trial. The group supplemented with ORIGORAN (T4) exhibited significant improvements (p<0.05) in body weight gain and FCR compared to the control group,and comparable results to the AGP (T2) and probiotic (T3) groups.Birds fed ORIGORAN showed healthier intestinal morphology, enhanced liver function, and improved immune response, as indicated by elevated lymphocyte counts and reduced heterophil-to-lymphocyte ratios. Serum biochemical profiles,including ALT, AST, and cholesterol levels, were within physiological limits, confirming the product's safety. Additionally, ORIGORAN supplementation reduced the colonization of pathogenic bacteria such as E.coli and Clostridium perfringens in the gut, suggesting strong antimicrobial activity. These findings demonstrate that ORIGORAN is an effective natural growth promoter that can enhance broiler performance, support gut health,and improve immunity without the adverse effects associated with AGPs. Its phytogenic composition provides a promising, residue-free alternative for antibiotic-free poultry production,aligning with global trends toward safe and sustainable animal farming.
