The study was to investigate the effects of garlic (Allium sativum) powder on feeding attraction activity, growth performance and digestive enzymes of juvenile Japanese seabass, Lateolabrax japonicus (initial weight: 29.82 ± 0.24 g). Six concentration gradients (0, 5, 10, 15, 20 and 25 g/kg diets) were formulated for luring and feeding experiment. The results showed a clear attractive trend of garlic powder for L. japonicus. A 28‐day feeding experiment indicated garlic could reduce the feed conversion ratio (FCR) (p < .05). The content of the body crude lipid was significantly increased at 10–15 g/kg diet (p < .05). Digestive enzyme activities including trypsin, amylase (AMS) and lipase (LPS) in the intestine were the highest at 10 g/kg diet (p < .05). Overall, garlic powder provides a promising and effective method for Japanese seabass healthy culture by improving fish growth and digestive ability. The results of this research suggested the additive suitable dosage of garlic powder was about 10 g/kg diet.

大蒜粉对日本鲈鱼取食性、生长和消化酶活性的影响

本研究旨在研究大蒜（Allium sativum）粉对日本鲈鱼幼鱼（初始重量：29.82 ± 0.24 g）的摄食吸引活性、生长性能和消化酶的影响。为引诱和喂养实验配制了六个浓度梯度（0、5、10、15、20 和 25 g/kg 饲料）。结果表明大蒜粉对L. japonicus具有明显的吸引力。一项为期 28 天的饲养实验表明，大蒜可以降低饲料转化率 (FCR) (p < .05)。在 10-15 g/kg 日粮中，身体粗脂的含量显着增加 (p < .05)。肠道中包括胰蛋白酶、淀粉酶 (AMS) 和脂肪酶 (LPS) 在内的消化酶活性在 10 g/kg 饮食时最高 (p < .05)。全面的，大蒜粉通过提高鱼的生长和消化能力，为日本鲈鱼的健康养殖提供了一种有前途和有效的方法。本研究结果表明大蒜粉的添加剂适宜用量约为10 g/kg日粮。
