This study investigates the effects of incorporating paper mulberry ( L.) powder into the diets of Cherry Valley ducks on growth performance, serum biochemistry, and the gut microbiome. A total of 350 14-day-old male Cherry Valley ducks were randomly assigned to five groups receiving diets with 0%, 4%, 6%, 8%, and 10% paper mulberry powder for 42 days. Growth performance, meat quality, serum immunity, and cecal microbial composition were assessed. The results showed no significant differences in average daily feed intake and feed conversion ratio among treatments, with the 6% paper mulberry group showing the highest average daily gain (79.73 g) ( < 0.05). Meat quality parameters, including color, drip loss, cooking loss, and shear force, were not significantly affected by paper mulberry powder supplementation, while the 8% paper mulberry group showed the highest pH value (5.47) ( < 0.05). Serum biochemistry revealed increased total protein (G0, G4, G6, G8, and G10: 41.50, 44.47, 45.58, 45.67, and 45.85 g/L, respectively), albumin (G0, G4, G6, G8, and G10: 18.61, 19.56, 20.29, 20.2, and 20.39 g/L, respectively), total cholesterol (G0, G4, G6, G8, and G10: 5.31, 4.96, 5.37, 5.53, and 5.59 mmol/L, respectively), and high-density lipoprotein cholesterol (HDL) in ducks fed 6%, 8%, and 10% paper mulberry powder, with lower alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBI) in the 8% and 10% groups ( < 0.05). Cecal microbial diversity was enhanced with paper mulberry powder, particularly in the 6% group, which showed increased Bacteroides abundance ( < 0.05). Supplementing duck diets with 6% paper mulberry powder increased average daily gain, without adversely affecting meat quality and health, suggesting its potential as a sustainable feed ingredient in the duck meat industry.
本研究调查了在樱桃谷鸭日粮中添加构树（L.）粉对其生长性能、血清生化指标和肠道微生物群的影响。总共350只14日龄雄性樱桃谷鸭被随机分为五组，分别饲喂含0%、4%、6%、8%和10%构树粉的日粮，为期42天。评估了生长性能、肉质、血清免疫和盲肠微生物组成。结果表明，各处理组的平均日采食量和饲料转化率无显著差异，6%构树粉组的平均日增重最高（79.73克）（P<0.05）。构树粉添加对肉质参数，包括颜色、滴水损失、蒸煮损失和剪切力没有显著影响，而8%构树粉组的pH值最高（5.47）（P<0.05）。血清生化指标显示，饲喂6%、8%和10%构树粉的鸭，其总蛋白（G0、G4、G6、G8和G10组分别为41.50、44.47、45.58、45.67和45.85克/升）、白蛋白（G0、G4、G6、G8和G10组分别为18.61、19.56、20.29、20.2和20.39克/升）、总胆固醇（G0、G4、G6、G8和G10组分别为5.31、4.96、5.37、5.53和5.59毫摩尔/升）和高密度脂蛋白胆固醇（HDL）有所增加，8%和10%组的丙氨酸氨基转移酶（ALT）、天冬氨酸氨基转移酶（AST）和总胆红素（TBI）较低（P<0.05）。构树粉可提高盲肠微生物多样性，尤其是6%组，其拟杆菌丰度增加（P<0.05）。在鸭日粮中添加6%构树粉可提高平均日增重，且对肉质和健康无不良影响，表明其在鸭肉产业中作为可持续饲料成分的潜力。
