摘要

摘要本试验旨在研究在常规养殖条件下,牛至油微胶囊饲料添加剂VISNAT 1对虹鳟鱼生长性能、肠道和皮肤组织形态学、血清生化指标、鱼片氧化状态和脂肪酸(FA)分布的影响。此外,还评估了胰岛素样生长因子-1 (IGF-1)和生长激素1 (GH-1)基因表达水平的变化。选取200尾亚成鱼(52 g±3.2),随机分为2个不同处理,每个处理4个重复。对照组饲喂基础饲粮,牛至组饲喂在饲粮中添加1.0 kg/t牛至精油的饲粮。结果表明,该植物制剂有利于改变饲料、鱼片和血清氧化状态,提高鳟鱼生产性能。此外,牛至精油对肠道和皮肤的组织病理学和组织形态学有有益的影响。此外,在虹鳟鱼饲料中添加牛至油可以启动肝脏的有丝分裂和抗凋亡反应,这是IGF-1受体促进身体生长和健康的主要作用之一。因此,牛至精油可以作为鳟鱼饮食的补充,但对其作用还需要进一步的研究。

Nano-oregano essential oil improves rainbow trout’s (Oncorhynchus Mykiss) growth performance, oxidative status, fatty acid profile of fillet, affects gene expression and supports skin and intestinal histomorphometry
Abstract The present study was conducted to investigate the effects of a microencapsulated oregano feed additive containing oregano essential oil named “VISNAT 1” on growth performance, intestinal and skin histomorphometry, serum biochemical parameters, fillet oxidative status and fatty acids (FA) profile of rainbow trout (Oncorhynchus mykiss) under conventional farming conditions. Also, changes in the expression levels of both Insulin-like growth factor-1 (IGF-1) and Growth hormone 1 (GH-1) genes were assessed. A total of 200 sub-adult trouts (52 g±3.2), were randomly allocated into two different treatments with four replicates each. The control group was fed a basal diet, while oregano group was fed diet supplemented with oregano essential oil at the level of 1.0 kg/t of feed. The results indicate that the phytobiotic product beneficially altered feed, fillet and serum oxidative status and improved performance of trouts. Also, oregano essential oil beneficially affected the histopathology and histomorphometry of intestine and skin. Moreover, oregano oil addition in the rainbow trout diet can initiate mitogenic and anti-apoptotic responses in the liver, which is one of the main actions of IGF-1 receptor promoting body growth and health. As a result, oregano essential oil can be used as a supplement on trouts diet but further investigation upon its action should take place.
