The effect of dietary inclusion of leaf powder (MLP) on the growth, meat quality, carcass characteristics, hematobiochemical profile, and cecal bacteria of broiler chicken was investigated in this research trial. In this study, 192-day-old Arbor Acre broiler chicks were assigned in a completely randomized design to three groups: control, antibiotic, and MLP. A standard basal diet was given to the control group, while the antibiotic group received 75 mg/kg chlortetracycline, and the MLP group received 100 mg/kg leaf powder supplemented basal diet. Each group was further divided into eight replicates consisting of eight birds each, and the trial ran for 35 days. Among the groups, the MLP-fed broilers achieved the highest final body weight (FBW), average daily gain (ADG), and average daily feed intake (ADFI). Notably, the FCR for the whole experimental period was lower in the MLP group, indicating a more efficient use of feed for growth. Supplementation of MLP with basal diet significantly increased ( < 0.05) the weight of thighs and drumsticks relative to live weight %, while the spleen and abdominal fat weight (% of live weight) were significantly decreased ( < 0.05). Adding MLP to the diet improved the meat quality of broilers, as indicated by the highest pH of meat at 45 min and the lowest cooking loss (%) observed in this group. MLP exhibited hypocholesterolemic and hypolipidemic effects, with the lowest total cholesterol and triglyceride levels compared to non-supplemented groups. The hematological profile revealed that the MLP group exhibited the highest RBC count and Hb level, while also showing the lowest H/L ratio. Moringa supplementation significantly ( < 0.05) modulated the cecal bacterial population, reducing pathogenic and spp. while increasing beneficial spp. and the total aerobic plate count (TAPC). In conclusion, leaf powder (MLP) can be used as a natural feed supplement for promoting the growth, meat quality, healthy blood, and sound health of broilers.
本研究试验考察了日粮中添加辣木叶片粉（MLP）对肉鸡生长性能、肉品质、胴体特性、血液生化指标及盲肠细菌的影响。本研究中，将192只1日龄的爱拔益加肉鸡雏鸡采用完全随机设计分为三组：对照组、抗生素组和MLP组。对照组饲喂标准基础日粮，抗生素组添加75 mg/kg金霉素，MLP组添加100 mg/kg辣木叶片粉的基础日粮。每组再分为8个重复，每个重复8只鸡，试验期为35天。在各试验组中，饲喂MLP的肉鸡最终体重（FBW）、平均日增重（ADG）和平均日采食量（ADFI）最高。值得注意的是，MLP组整个试验期的料重比（FCR）较低，表明饲料转化为生长的效率更高。基础日粮中添加MLP显著提高了（P<0.05）大腿和小腿相对于活体重的百分比，而脾脏和腹脂重量（占活体重的百分比）显著降低（P<0.05）。日粮中添加MLP改善了肉鸡的肉品质，该组在45分钟时肉的pH值最高，烹饪损失率（%）最低。MLP具有降胆固醇和降血脂作用，与未添加组相比，总胆固醇和甘油三酯水平最低。血液学指标显示，MLP组红细胞计数（RBC）和血红蛋白水平（Hb）最高，同时H/L比值最低。添加辣木显著（P<0.05）调节了盲肠细菌菌群，减少了致病性大肠杆菌和沙门氏菌，同时增加了有益的乳酸菌和总需氧平板计数（TAPC）。总之，辣木叶片粉（MLP）可作为天然饲料添加剂，促进肉鸡生长、改善肉品质、维持血液健康和整体健康。
