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.
本研究旨在确定牛膝提取物(AJE)补充到玉米-豆粕-小麦基础日粮中对肉鸡生长性能、养分消化率、盲肠微生物区系、粪便有害气体排放和肉质的影响。选用 432 只 1 日龄雄性罗斯 308 肉鸡,初始体重(IBW)为 41.11±1.65g,随机分为 4 种日粮处理。每个处理有 6 个重复笼,每个笼有 18 只肉鸡。日粮处理由玉米-小麦-豆粕基础日粮组成,并添加 0、0.025、0.05 和 0.1%的 AJE。AJE 补充在第 1 期和第 2 期以及整个试验期间线性影响体重增重(BWG)和平均日采食量(ADFI)。随着 AJE 添加水平的增加,干物质(DM)的消化率在第 35 天呈线性提高。日粮中添加不同水平的 AJE 对盲肠乳酸菌、大肠杆菌和沙门氏菌计数、粪便有害气体氨、硫化氢、总硫醇、二氧化碳、乙酸和丙酸排放、肉质和相对器官重量没有显著影响。因此,我们得出结论,日粮中添加 0.1%的 AJE 可以提高肉鸡的 BWG 和 ADFI,提高干物质消化率。
