Abstract Mushroom (Flammulina velutipes) stem residue (MSR) is rich with bioactive ingredients. This study aimed to assess the role of mushroom stem residue (MSR) on growth performance, meat quality, antioxidant status, and lipid metabolism of broilers. A total 168 Arbour Acres male broilers were assigned into 3 treatments (7 replications, 8 chicks each) and fed a basal diet as control (CON); 1% mushroom stem residue containing diet (1% MSR); and 2% MSR containing diet. Superoxide dismutase, glutathione peroxidase, and catalase value in serum, thigh muscle, breast muscle and liver sample, were higher (linear and quadratic, p < .05) in MSR groups than that of CON. Malondialdehyde content in serum, thigh muscle, breast muscle and liver tissue sample, were lower (linear and quadratic, p < .05) in MSR diets than CON. Compared with control, total cholesterol value of liver sample was lower (linear and quadratic, p < .05) in 2% MSR diet on day 21 and day 42. Triglyceride value was also lower (linear and quadratic, p < .05) in both levels of MSR diets than control on day 21 and day 42. MSR at 2% level can be applied on improving antioxidant status and lipid metabolism of broilers. HIGHLIGHTS Flammulina velutipes mushroom stem residue (MSR) contains different bio-active ingredients which can be used in broiler diets. MSR had no any adverse effects on growth performance and normal meat quality of broilers. MSR could improve different antioxidant enzyme activities in breast muscle, thigh muscle, liver tissue and serum of broilers. MSR could reduce cholesterol levels in liver tissue of broilers. MSR at 2% level can be applied on improving antioxidant status and lipid metabolism in broilers.

蘑菇（金针菇）茎残留对肉鸡生长性能、肉质、抗氧化状态和脂质代谢的影响

摘要 香菇（Flammulina velutipes）茎渣（MSR）富含生物活性成分。本研究旨在评估蘑菇茎渣 (MSR) 对肉鸡生长性能、肉质、抗氧化状态和脂质代谢的作用。总共 168 只 Arbor Acres 雄性肉鸡被分配到 3 个处理组（7 次重复，每组 8 只小鸡）并饲喂基础日粮作为对照 (CON)；含 1% 蘑菇茎残渣的饮食（1% MSR）；和含 2% MSR 的饮食。MSR 组的血清、大腿肌肉、胸肌和肝脏样本中的超氧化物歧化酶、谷胱甘肽过氧化物酶和过氧化氢酶值高于 CON 组（线性和二次方，p < .05）。MSR 饮食中血清、大腿肌肉、胸肌和肝脏组织样本中的丙二醛含量低于 CON 饮食（线性和二次型，p < .05）。与对照相比，在第 21 天和第 42 天，2% MSR 饮食中肝脏样本的总胆固醇值较低（线性和二次方，p < .05）。两个 MSR 水平的甘油三酯值也较低（线性和二次方，p < .05）第21天和第42天的日粮比对照高。2%水平的MSR可用于改善肉鸡的抗氧化状态和脂质代谢。亮点金针菇蘑菇茎渣 (MSR) 含有不同的生物活性成分，可用于肉鸡日粮。MSR对肉鸡的生长性能和正常肉质没有任何不利影响。MSR可提高肉鸡胸肌、大腿肌、肝组织和血清中不同抗氧化酶的活性。MSR可以降低肉鸡肝组织中的胆固醇水平。
