Olive leaves have been used traditionally to improve the immunity against several infections. Current study aimed to examine the effect of fortified feed with olive leaves extract on haematological and biochemical parameters of . Total 400 healthy fish were divided randomly into four groups and were cultured for two months in glass tanks of 250 L water capacity in triplicate. Fortified feed was prepared with various extract, 1%, 1.5% and 2% concentration in diet, while, control-group diet was without extraction. Results showed that all the haematological parameters including WBC, RBC, Hb, PCV and plasma protein were significantly increased while the biochemical parameters such as globulin albumen ratio increased in fish which fed on 1% of extract, but the level of cholesterol and triglycerides was decreasing by increasing the concentration of extract. It was concluded that olive leaves extract can be used to enhance the immunity, growth and health of fish.
橄榄叶传统上被用于提高对多种感染的免疫力。本研究旨在探讨添加橄榄叶提取物的强化饲料对. 的血液学和生化参数的影响。将 400 条健康鱼随机分为 4 组，在 250 升水容量的玻璃缸中，每缸 3 重复，养殖 2 个月。强化饲料用不同浓度的提取物（1%、1.5%和 2%）和对照组（无提取物）制备。结果表明，1%提取物组鱼类的所有血液学参数（包括白细胞、红细胞、血红蛋白、红细胞压积和血浆蛋白）均显著升高，球蛋白白蛋白比等生化参数也升高，但随着提取物浓度的增加，胆固醇和甘油三酯的水平下降。结论：橄榄叶提取物可用于增强鱼类的免疫力、生长和健康。
