ABSTRACT: This research was conducted to determine the effects Achyranthes japonica extract (AJE) supplementation to corn-soybean meal-wheat-based diet on the growth performance, nutrient digestibility, cecal microflora, excreta noxious gas emission, and meat quality of broiler chickens. A total of 432 one-day-old male Ross 308 broiler chickens, having initial body weight (IBW) of 41.11 ± 1.65 g were randomly allotted to 4 dietary treatments. Each treatment had 6 replicates cages with 18 broilers per cage. Dietary treatments composed of corn–wheat–soybean meal–based diets along with the addition of 0, 0.025, 0.05, and 0.1% of AJE. Bodyweight gain (BWG) and average daily feed intake (ADFI) were linearly influenced by the supplementation of AJE duringphase1 and 2 and the overall trial period. Inclusion of increasing levels of AJE linearly improved the digestibility of dry matter (DM) on d 35. Dietary supplementation of increasing levels of AJE failed to show significant effects on cecal Lactobacillus, coliform, and Salmonella counts, excreta noxious gas ammonia, hydrogen sulfide, total mercaptans, carbon dioxide, acetic acid and propionic acid emission, meat quality, and relative organ weight. Therefore, we concluded that supplementation of 0.1% of AJE in diets could improve BWG and ADFI, dry matter digestibility in broilers.
