Recently, prioritize has been given to using natural phytogenic or nano compounds as growth promoters and immunostimulants in fish diets as an alternative to antibiotics.
The main propose of this trial was to determine the impact of supplementing diets with spirulina or curcumin nanoparticles on the performance and health indicators of Nile tilapia fingerlings.
In a 56-day feeding trial, 180 tilapia fingerlings were assigned into three main groups, as follows: 1st, control group, 2nd, Spirulina platensis (SP; 5 g kg diet) and 3rd, curcumin nanoparticles (CUR-NPs; 30 mg kg diet).
Incorporating tilapia diets with SP or CUR-NPs significantly improved performance, body chemical analysis, blood biochemical and hematological indices, digestive enzyme activities, and antioxidant and immunostimulant features compared to the control.
Fortified tilapia diets with CUR-NPs or SP efficiently boost the productivity and health of Nile tilapia fingerlings.
The research introduces new practical solutions for applying safe feed additives as alternatives to antibiotics in tilapia farming.
最近，人们优先考虑在鱼类饲料中使用天然植物或纳米化合物作为生长促进剂和免疫刺激剂，以替代抗生素。
本试验的主要目的是确定在饲料中添加螺旋藻或姜黄素纳米粒子对尼罗罗非鱼鱼苗生长性能和健康指标的影响。
在为期 56 天的饲养试验中，将 180 尾罗非鱼鱼苗分为三组：1. 对照组；2. 螺旋藻（SP；5 g kg 饲料）；3. 姜黄素纳米粒子（CUR-NPs；30 mg kg 饲料）。
与对照组相比，在罗非鱼饲料中添加 SP 或 CUR-NPs 显著提高了生长性能、体化学成分分析、血液生化和血液学指标、消化酶活性以及抗氧化和免疫刺激特性。
在尼罗罗非鱼鱼苗饲料中添加 CUR-NPs 或 SP 可有效提高尼罗罗非鱼鱼苗的生产力和健康水平。
本研究为在罗非鱼养殖中应用安全的饲料添加剂替代抗生素提供了新的实用解决方案。
