This study investigated the effects of Setipinna taty protein peptides on the growth, body composition, antioxidant ability and intestinal flora of juvenile Nibea albiflora. The results of this study indicated that there were no significant differences between the control and experimental groups regarding survival, specific growth rate (SGR), feed conversion rate (FCR) and body composition (p > 0.05). Also, there were no significant differences among the control and experimental groups regarding the superoxide dismutase (SOD), glutathione peroxidase (GSH‐PX) and malondialdehyde (MDA) contents of juvenile Nibea albiflora (p > 0.05). For catalase (CAT), the contents of the 42 mg/ml and 21 mg/ml groups were significantly higher than that of the control group (p < 0.05). Regarding lysozyme (LYZ), the content of the 42 mg/ml group was significantly higher than those of the control and 21 mg/ml groups (p < 0.05). The alpha diversity did not exhibit significant differences between the control and experimental groups (p > 0.05). At the phylum level, the dominant intestinal flora in the experimental groups were Tenericutes and Proteobacteria, which accounted for approximately 90.94% of the total flora. At the genus level, Mycoplasma was more abundant in the control group, and Marivita and Qidonghai fungi were the dominant genera in the experimental groups. The results of this study demonstrated that the Setipinna taty protein peptides can change the abundance of the dominant community in the intestine of juvenile Nibea albiflora.

Setipinna taty蛋白肽对白花苜蓿生长，身体成分，抗氧化能力和肠道菌群的影响

这项研究调查了Setipinna taty蛋白肽对幼龄Nibea albiflora的生长，身体组成，抗氧化能力和肠道菌群的影响。这项研究的结果表明，对照组和实验组在存活率，比生长率（SGR），饲料转化率（FCR）和身体组成方面无显着差异（p  > 0.05）。另外，有控制中和关于超氧化物歧化酶（SOD），谷胱甘肽过氧化物酶（GSH-PX）和少年丙二醛（MDA）的含量没有差异显著实验组黄姑鱼（p > 0.05）。对于过氧化氢酶（CAT），42 mg / ml和21 mg / ml组的含量显着高于对照组（p  <0.05）。关于溶菌酶（LYZ），42 mg / ml组的含量显着高于对照组和21 mg / ml组（p  <0.05）。在对照组和实验组之间，α多样性没有显着差异（p  > 0.05）。在门的水平上，实验组中主要的肠道菌群是Tenericutes和Proteobacteria，约占菌群总数的90.94％。在属水平上，对照组中支原体含量较高，而Marivita和启东海真菌含量较高。是实验组中的主要属。这项研究结果表明，Setipinna taty蛋白肽可以改变幼龄Nibea albiflora肠道中优势群落的数量。
