In the study, effects of S. officinalis essential oil on growth performance, health and antioxidant activity in C. carpio were investigated. The fish (13 ± 0.21 g) were fed with diet containing 1 and 3 ml kg of sage oil for 60 days. At the end of study, growth performance was not affected in fish fed with sage essential oil (p > 0.05). Superoxide dismutase (SOD) activity in hepatopancreas increased with addition of 1ml kg sage oil to the diet. However, Catalase (CAT) activity and malondialdehyde (MDA) values were not significantly altered in common carp. Total protein, albumin, glucose and hepatopancreas enzymes (aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP)) in blood serum were not affected by sage essential oil supplementation. At the histological examinations, no pathological findings were observed in hepatopancreas and intestine of carp. Goblet cells number and villi length in intestine increased with sage supplementation (p < 0.001). In addition, fertility, granulation and number of follicles increased in common carp fed with sage essential oil. Mortality after challenged with A. hydrophila was not observed in carp fed with 1ml kg concentration of sage essential oil. As a result, use of sage oil can be recommended in carp farming to improve gut health, provide disease resistance against A. hydrophila infection, and increase of fertility.
在这项研究中，研究了迷迭香精油对鲤鱼生长性能、健康和抗氧化活性的影响。将 13±0.21g 的鱼用含有 1 和 3ml/kg 迷迭香油的饲料喂养 60 天。研究结束时，喂食迷迭香油的鱼的生长性能没有受到影响（p>0.05）。添加 1ml/kg 迷迭香油到饲料中可增加肝胰腺中超氧化物歧化酶（SOD）的活性。然而，鲤鱼的过氧化氢酶（CAT）活性和丙二醛（MDA）值没有显著改变。血清中的总蛋白、白蛋白、葡萄糖和肝胰腺酶（天冬氨酸氨基转移酶（AST）、丙氨酸氨基转移酶（ALT）、碱性磷酸酶（ALP））不受迷迭香油补充的影响。在组织学检查中，在肝胰腺和肠道中没有观察到病理发现。肠道中的杯状细胞数量和绒毛长度随着迷迭香的补充而增加（p<0.001）。此外，喂食迷迭香精油的鲤鱼的繁殖力、颗粒形成和卵泡数量增加。在喂食 1ml/kg 浓度的迷迭香油的鲤鱼中，没有观察到感染嗜水气单胞菌后的死亡率。因此，在鲤鱼养殖中使用迷迭香油可以改善肠道健康，提供对嗜水气单胞菌感染的抵抗力，并提高繁殖力。
