Achyranthes japonica extract as phytogenic feed additive enhanced nutrient digestibility and growth performance in broiler

<italic>Achyranthes japonica</italic> extract (AJE) is derived from a medicinal plant japonica</italic>, known for its anti-inflammatory, antioxidant, and antimicrobial properties. AJE contains multiple bioactive compounds, including saponins, triterpenoids, phytoecdysteroids, 20-hydroxyecdysone, inokosterone. Aim of this investigation was to examine the impact as phytogenic feed additive on growth performance, nutrient digestibility, excreta microbial count, noxious gas emissions, breast meat quality in broilers. About three hundred sixty, day-old broilers (Ross 308) were assigned into four treatments (five replication cages/treatment, 18 birds/case). Dietary treatments: CON, basal diet; 0.02% AJE, diet with 0.02%; 0.04% 0.06% AJE. Body weight gain increased linearly (<italic>p</italic> < 0.05) through inclusion during days 7 21, 21 35, well entire experimental period. Besides, intake 35 experiment doses broiler diet. Dry matter digestibility along increasing amounts With supplementation, nitrogen energy utilization tended improve 0.10). In summary, addition corn-soybean meal led higher body enhanced among them highest improvement found 0.06%-AJE indicating acceptance additive.
