The present study evaluated the effects of dietary yeast supplementation on the growth and blood parameters of . Fish were fed with commercial feed supplemented with NuPro® at 0, 10, 40 and 80 g / kg for 30 days and, did not exhibit any difference in growth. Blood was analyzed at the end of the feeding trial and after handling stress. A significant reduction in albumin and triglycerides levels was observed with increased supplementation of NuPro® in the diet of . The interactive effect of diet and stress influenced plasma glucose levels, with a modulation at all levels of supplementation after stress, while in the control group the level was significantly high. NuPro® improved the innate immune response of at all the tested concentrations, with a significantly higher levels number of thrombocytes, leukocytes, lymphocytes, monocytes, and neutrophils than the control group. There was also an increase in the number of thrombocytes after stress. As the inclusion of NuPro® in the diet improved the innate immune response at all the concentrations tested and effectively modulated plasma glucose levels, this product can be recommended as an immunostimulant for fingerlings with the inclusion of 40 g/kg of feed.

添加酵母的饮食改善了巨骨舌鱼的先天免疫反应


本研究评估了膳食酵母补充剂对生长和血液参数的影响。用添加了 0、10、40 和 80 g/kg NuPro® 的商业饲料喂养鱼 30 天，没有表现出任何生长差异。在喂养试验结束时和处理应激后对血液进行分析。通过在饮食中增加 NuPro® 的补充，观察到白蛋白和甘油三酯水平显着降低。饮食和压力的相互作用影响了血浆葡萄糖水平，压力后各个补充水平都受到调节，而对照组的水平明显较高。 NuPro® 改善了所有测试浓度的先天免疫反应，血小板、白细胞、淋巴细胞、单核细胞和中性粒细胞的数量显着高于对照组。应激后血小板数量也有所增加。由于在日粮中添加 NuPro® 可改善所有测试浓度下的先天免疫反应，并有效调节血浆葡萄糖水平，因此该产品可推荐作为鱼种的免疫刺激剂，添加量为 40 g/kg 饲料。
