This study was conducted to evaluate the effect of rosemary (Rosmarinus officinalis) leaf powder (RLP) at 0.0% (control), 0.5%, 1% and 2% as a dietary supplement for eight weeks, on the growth performance, carcass composition and haemato-biochemical parameters. One hundred twenty common carp (Cyprinus carpio) (21.11±0.17g) were randomly distributed to 12 cages (0.2 m3) with three replicates for 56 days. The results showed that RLP-supplemented diets achieved significant enhancement of growth performance (FBW, SGR and WG) and feed utilization (FCR, FCE and PI) compared with a control group. In addition, TFI and PI were significantly improved in 0.5 and 2% RLP-supplemented groups. RLP had no significant effects on body composition except moisture content which was significantly increased in fish fed with a 1% supplemented diet and crude protein which was significantly decreased in fish fed with a 1% supplemented diet compared to the control diet. The results showed a significant increase in RLP-supplemented diets in RBC counts, LYM, MCV, hematocrit, total protein, albumin and globulin compared with the control group. WBC counts significantly increased in fish fed the 0.5 and 2% RLP diets, and hemoglobin significantly elevated in fish fed the 1% RLP diet. Glucose, GRA, MCH, MCHC and MPV were significantly decreased in the group fed the RLP diets compared with the control group. The AST, ALT, LDL, VLDL, CHO and TG levels showed a significant decrease in RLP compared to the control diet (P < 0.05), while ALP level fluctuated (P > 0.05). The urea and creatinine levels were higher in the RLP groups compared with the control (P < 0.05). Dietary RLP 1% increased lipase when compared to the control group. However, amylase levels in fish fed 0.5 and 1% RLP has significantly improved, while fish fed 2% RLP has significantly decreased when compared to the control diet. Overall, the results demonstrated that dietary RLP supplementation enhanced the growth and health status of common carp.
本研究旨在评估迷迭香（Rosmarinus officinalis）叶粉（RLP）以 0.0%（对照）、0.5%、1%和 2%作为膳食补充剂，连续喂养 8 周对生长性能、胴体组成和血液生化参数的影响。120 条鲤鱼（Cyprinus carpio）（21.11±0.17g）被随机分配到 12 个笼子（0.2 m3）中，每个笼子 3 个重复，共 56 天。结果表明，与对照组相比，RLP 补充饲料显著提高了生长性能（FBW、SGR 和 WG）和饲料利用率（FCR、FCE 和 PI）。此外，在 0.5%和 2%RLP 补充组中 TFI 和 PI 显著提高。除了饲料中添加 1%RLP 组的水分含量显著增加和粗蛋白含量显著降低外，RLP 对体成分没有显著影响。与对照组相比，RLP 补充饲料显著增加了红细胞计数、LYM、MCV、红细胞压积、总蛋白、白蛋白和球蛋白。在 0.5%和 2%RLP 饲料组中白细胞计数显著增加，在 1%RLP 饲料组中血红蛋白显著升高。与对照组相比，葡萄糖、GRA、MCH、MCHC 和 MPV 在 RLP 喂养组中显著降低。与对照组相比，AST、ALT、LDL、VLDL、CHO 和 TG 水平显著降低（P<0.05），而 ALP 水平波动（P>0.05）。与对照组相比，RLP 组的尿素和肌酐水平更高（P<0.05）。与对照组相比，1%RLP 组的脂肪酶水平升高。然而，0.5%和 1%RLP 组的淀粉酶水平显著提高，而 2%RLP 组的淀粉酶水平显著降低。总的来说，结果表明，日粮 RLP 补充剂可增强鲤鱼的生长和健康状况。
