本研究旨在评估BioPlus 2B（一种含有地衣芽孢杆菌和B的益生菌）的功效。枯草杆菌和铁蛋白溶液对库图姆、弗氏红鲤库图姆、鱼苗生长性能、体成分和血液学指标的影响。在卵黄囊吸收后，将含有各种比例的益生菌和铁蛋白的干颗粒饲喂鱼60天。试验结束时，生长指数（最终体重、增重、特定生长率、日生长率、食物转化率和条件因子）、身体组成（粗蛋白、粗脂质、灰分和水分）和血液学参数[红细胞压积（Hct）、血红蛋白（Hb）、红细胞（RBC）、白色细胞（WBC）、中性粒细胞（NEUTR）、淋巴细胞（LYM）、平均细胞体积（MCV）、平均细胞血红蛋白（MCH）和平均细胞血红蛋白浓度（MCHC）]。关于身体组成，与对照组相比，接受益生菌和铁蛋白处理的鱼的总蛋白水平较高，灰分、水分和脂质水平较低（P < 0.05）。接受补充有益生菌和铁蛋白溶液的饮食的鱼显示出比饲喂基础饮食（对照）的鱼显著更好的生长。RBC、Hct、Hb、MCV、MCH和LYM在饲喂益生菌（1.6 × 10（9）CFU/g干颗粒）+铁蛋白溶液（7 mg/kg干颗粒）+干颗粒的鱼中均最高。这些结果表明，益生菌和铁蛋白溶液的组合代表了一种有效的膳食补充剂，用于改善库图姆鱼苗的胴体品质、生长性能和血液学参数。
This study aimed to assess the efficacy of BioPlus 2B, a probiotic containing Bacillus licheniformis and B. subtilis and Ferroin solution on growth performance, body composition and haematological parameters in kutum, Rutilus frisii kutum, fry. The fish were fed dry pellets containing various ratios of probiotics and Ferroin for 60 days after absorption of the yolk sac. At the end of the trial, growth indices (final weight, weight gain, specific growth rate, daily growth rate, food conversion ratio and condition factor), body composition (crude protein, crude lipid, ash and moisture) and haematological parameters [haematocrit (Hct), haemoglobin (Hb), red blood cells (RBC), white blood cells (WBC), neutrophils (NEUTR), lymphocytes (LYM), mean cell volume (MCV), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC)] were assessed. Regarding body composition, total protein levels were higher, and ash, moisture and lipid levels were lower in fish receiving the probiotic and Ferroin treatments compared with the control group (P < 0.05). Fish receiving diets supplemented with probiotics and Ferroin solution showed significantly better growth than those fed the basal diet (control). RBC, Hct, Hb, MCV, MCH and LYM were all highest in fish fed probiotic (1.6 x 10(9) CFU/g dry pellet) + Ferroin solution (7 mg/kg dry pellet) + dry pellets. These results indicate that the combination of probiotic and Ferroin solution represents an effective dietary supplement for improving carcass quality, growth performance and haematological parameters in kutum fry.
