A total of 480 one-day-old Arbor Acres broiler chicks were randomly assigned to four dietary groups, each including six replicates (n = 20/replicate). Broilers in the first group (G1) were fed a basal diet without any additives (control). Broilers in groups 2, 3 and 4 (G2, G3 and G4) were fed a basal diet supplemented with 0.1%, 0.2% and 0.4% coriander (Coriandrum sativum L.) seed powder (CSP) respectively. Feeding trials lasted for 42 days, and after that growth, carcass traits, haematological parameters, gut microbiota and economic efficiency (EE) were evaluated. Final body weight (FBW), total weight gain (TWG), total feed intake (TFI) and red blood cell (RBC) counts of broilers in the G4 and G3 treatment groups were significantly higher (p < .05) compared with broilers in the G1 treatment group. The feed conversion ratio (FCR) was better (p < .05) in the G4 treatment group (1.72) than in the G1 treatment group (1.84). Broilers in CSP treatment groups had significantly higher haemoglobin (Hb) concentrations, packed cell volume (PCV) and platelet counts, and had lower (p < .05) Escherichia coli and Clostridium perfringens counts compared with broilers in the G1 treatment group. Dressing, liver, pancreas, bursa and thymus percentages were higher (p < .05) in broilers in the G4 (70.30, 3.18, 0.31, 0.10 and 0.32% respectively) treatment group, compared with broilers in the control (G1) group (66.57, 2.37, 0.23, 0.04 and 0.21% respectively). Broilers in treatment groups G4 and G3 had lower percentages of abdominal fat and lower total bacterial counts (p < .05) than broilers in treatment groups G2 and G1. The highest economic efficiency (EE) was found in treatment group G4, and EE in this group was 13.06% greater than in the control (G1) group.
总计 480 只 1 日龄 Arbor Acres 肉鸡雏鸡被随机分配到四个日粮组，每个日粮组包括 6 个重复（n=20/重复）。第一组（G1）的肉鸡饲喂基础日粮，不添加任何添加剂（对照）。第二组、第三组和第四组（G2、G3 和 G4）的肉鸡分别饲喂基础日粮添加 0.1%、0.2%和 0.4%的芫荽（芫荽，Coriandrum sativum L.）籽粉（CSP）。饲养试验持续 42 天，然后评估生长性能、屠体特性、血液学参数、肠道微生物群和经济效益（EE）。G4 和 G3 处理组的肉鸡最终体重（FBW）、总增重（TWG）、总采食量（TFI）和红细胞（RBC）计数均显著高于（p<.05）G1 处理组。G4 处理组（1.72）的饲料转化率（FCR）优于（p<.05）G1 处理组（1.84）。CSP 处理组的肉鸡血红蛋白（Hb）浓度、红细胞压积（PCV）和血小板计数显著升高（p<.05），大肠杆菌和产气荚膜梭菌计数显著降低（p<.05），G1 处理组。G4 处理组的肉鸡屠宰率、肝脏、胰腺、法氏囊和胸腺百分比较高（p<.05），分别为 70.30%、3.18%、0.31%、0.10%和 0.32%，对照组（G1）为 66.57%、2.37%、0.23%、0.04%和 0.21%。G4 和 G3 处理组的肉鸡腹部脂肪百分比和总细菌计数较低（p<.05），而 G2 和 G1 处理组的肉鸡腹部脂肪百分比和总细菌计数较高。G4 处理组的经济效益（EE）最高，比对照组（G1）高 13.06%。
