Raw data of growth, hematology an, antioxidant activities enzyme in Oreochromis niloticus fed guava leaf extract meals.

The data is for an 84-day feeding trial on Nile tilapia (Oreochromis niloticus) fed diets with aqueous Psidium guajava leaf extract (PGE). Growth, intestinal morphology, and antioxidative properties were evaluated. A 30% crude protein basal diet was formulated. Concentrated extract (PGE) was dried into powder in hot air-oven at 30oC and mixed with the other feed ingredients at 0.25, 0.50, 0.75 and 1.00% (Diets T1, T2, T3, and T4 respectively). The result indicates that more feed was consumed in groups of fish fed PGE treated diets. Villi length and width were presented. and the area of absorption calculated. Antioxidant enzyme activities and oxidative marker including total protein, superoxide dismutase, glutathione peroxidase, and glutathione s-transferase were examined in fish.本数据集源自一项针对尼罗罗非鱼（Oreochromis niloticus）开展的84天饲喂试验，试验组鱼类饲喂添加番石榴叶水提取物（aqueous Psidium guajava leaf extract，PGE）的日粮。本试验对受试鱼的生长性能、肠道形态及抗氧化特性进行了评估。研究人员配制了粗蛋白含量为30%的基础日粮；将浓缩PGE置于30℃热风烘箱中干燥制成粉末，随后以0.25%、0.50%、0.75%及1.00%的比例与其他饲料原料混合，分别对应日粮组T1、T2、T3、T4。试验结果显示，饲喂添加PGE日粮的各组鱼类摄食量更高。本研究测定了肠绒毛的长度与宽度，并计算了肠道吸收面积；同时检测了鱼类体内的抗氧化酶活性与氧化应激标志物，包括总蛋白、超氧化物歧化酶、谷胱甘肽过氧化物酶以及谷胱甘肽S-转移酶。
