摘要

在新西伯利亚州立大学兽医和生物技术研究所药理学和普通病理学教研室的实验条件下,研究了基于枯草芽孢杆菌菌株 DSM 32424(活性成分浓度为 106 CFU/g)的益生菌制剂 Vetom 1 对日本鹌鹑产蛋量的影响。药物剂量分别为 50、75 和 100 毫克/千克活体重。按照《欧洲保护用于实验或其他科学目的的脊椎动物公约》[1]饲养鹌鹑,并进行初步适应性检疫,结果所有实验组(实验组和完整组)的产蛋率均为 0.30±014(σ² =4.58)。在益生菌 Vetom 1 的作用下,日本鹌鹑的雌性产蛋率有所提高,这种变化在整个剂量谱变化中具有直接的剂量依赖性。使用所研究的制剂后,实验组鹌鹑的蛋重指标变异水平与对照组的高变异统计背景指标相比有所下降。这种变化具有剂量依赖性。使用益生菌制剂 Vetom 1 可以减少负面环境因素(技术压力)对鸟类产蛋的影响,在使用不同剂量的益生菌制剂时,实验组鸟类的产蛋频率同步。

About the influence of a microbial preparation on the egg production of quail
In experimental conditions of the vivarium at the Department of Pharmacology and General Pathology of the Institute of Veterinary Medicine and Biotechnology of Novosibirsk GAU the effect of the probiotic preparation Vetom 1 based on the microorganism Bacillus subtilis strain DSM 32424 with a concentration of the active component 106 CFU/g on egg production of Japanese quail was studied. The drug was applied in doses of 50, 75 and 100 mg/kg live body weight. The birds were kept in accordance with the European Convention for the Protection of Vertebrate Animals Used for Experiments or Other Scientific Purposes [1] and underwent a preliminary adaptation quarantine, which resulted in an egg-laying rate of 0.30±014 (σ² =4.58) in all experimental (experimental and intact groups). Under the action of probiotic Vetom 1 there is an increase in the proportion of egglaying females of Japanese quail, the changes have a direct dose-dependent character on the whole change of the dose spectrum. At application of the studied preparation there is a decrease in the level of variability of egg weight indicator in quails of experimental groups in comparison with statistically highly variable background indicators of the control group. The changes have a dose-dependent character. The use of probiotic preparation Vetom 1 reduces negative environmental factors (technological stress) impact on egg production of birds, synchronizing the frequency of egg-laying in experimental birds at different dosages of probiotic preparation application.
