An 8-week study was conducted to evaluate three different diets supplemented with bovine lactoferrin (LF) at 0 (control), 800, and 1200 mg LF kg diet on somatic growth, hemato-immunological parameters, antioxidant status, and digestive enzyme activities in silvery-black porgy (Sparidentex hasta) juveniles. Fish fed the 800 mg LF kg diet had higher growth performance and feed utilization parameters than the other groups. Hematological and liver antioxidant parameters were not affected by dietary LF supplementation. Fish fed the 800 mg LF kg diet had higher plasma lysozyme activity values than the other groups. Total protease activity was higher in fish fed LF-supplemented diets than the control group. Results indicated that diet supplemented with 800 mg kg for 8 weeks enhanced somatic growth performance, lysozyme activity, and proteolytic digestive enzyme activities in S. hasta, as well as improving feed efficiency parameters like the protein efficiency and feed conversion ratios.
一项为期 8 周的研究评估了在三种不同的饮食中添加牛乳铁蛋白（LF），添加量分别为 0（对照组）、800 和 1200mg LF/kg 饲料，对黑鲷（Sparidentex hasta）幼鱼的体生长、血液免疫参数、抗氧化状态和消化酶活性的影响。摄食 800mg LF/kg 饲料的鱼比其他组具有更高的生长性能和饲料利用参数。血液和肝脏抗氧化参数不受 LF 饲料添加的影响。摄食 800mg LF/kg 饲料的鱼的血浆溶菌酶活性值高于其他组。添加 LF 的饲料组的总蛋白酶活性高于对照组。结果表明，在 8 周的时间里，饲料中添加 800mg/kg LF 可增强 S. hasta 的体生长性能、溶菌酶活性和蛋白水解消化酶活性，并提高蛋白质效率和饲料转化率等饲料效率参数。
