The study was to investigate effects of asafoetida (Ferula sinkiangensis K. M. Shen) powder on feeding attraction activity (FAA), growth performance, healthiness, and digestive enzyme activity of juvenile Lateolabrax japonicus. Six concentration levels (0, 5, 10, 15, 20, and 25 g/kg diets) were formulated for luring and feeding experiment. Results showed that asafoetida could stimulate the appetite of L. japonicus at the dietary levels from 10 to 25 g/kg; reduce the feed conversion ratio (FCR) and feed intake (FI) at 10–20 g/kg; increase the weight gain (WG) and specific growth rate (SGR) at 5–10 g/kg; increase the hepatosomatic index (HSI), body crude lipid content, serum total protein (TP) content, and lysozyme activity at 10–15 g/kg; decrease the moisture at 10–15 g/kg; and increase the serum total superoxide dismutase (T-SOD) activity at 5–15 g/kg, when compared with the control group (p < 0.05). Digestive enzyme activities including amylase (AMS) and trypsin in the intestine were significantly affected by the asafoetida powder (p < 0.05). Regression analyses between the FAA, FCR, WG, SGR, HSI, LZM, T-SOD, AMS, trypsin, and the dietary asafoetida powder levels showed that the optimal additional amount was 16.95, 13.65, 8.36, 8.15, 15.45, 9.94, 8.75, 11.77, and 7.07 g/kg, respectively, indicating that the optimal amount of asafoetida powder was located in 7.07–16.95 g/kg diet. However, combined with the significant difference analyses obtained from the current study, we would suggest the additive suitable dosage was 10 g/kg.

本研究旨在研究细叶阿魏酸粉对幼年日本鲈鱼的摄食引诱活性（FAA），生长性能，健康性和消化酶活性的影响。制定了六个浓度水平（0、5、10、15、20和25 g / kg饲料）用于诱饵和喂养实验。结果表明，沙枣能刺激日本刺槐的食欲。饮食水平为10至25克/千克；将饲料转化率（FCR）和饲料摄入量（FI）降低10–20 g / kg；以5-10 g / kg的体重增加体重（WG）和比生长速率（SGR）；以10–15 g / kg的剂量增加肝体指数（HSI），体内粗脂质含量，血清总蛋白（TP）含量和溶菌酶活性；以10–15 g / kg减少水分；与对照组相比，血清总超氧化物歧化酶（T-SOD）活性提高了5–15 g / kg（p  <0.05）。肠球菌粉对肠道中的消化酶活性（包括淀粉酶（AMS）和胰蛋白酶）有显着影响（p <0.05）。FAA，FCR，WG，SGR，HSI，LZM，T-SOD，AMS，胰蛋白酶和日粮中粉尘含量之间的回归分析表明，最佳添加量为16.95、13.65、8.36、8.15、15.45、9.94、8.75分别为11.77和7.07 g / kg，这表明最佳剂量的粉虱粉位于7.07–16.95 g / kg的日粮中。但是，结合当前研究获得的显着性差异分析，我们建议添加剂的合适剂量为10 g / kg。
