摘要
Probiotic bacteria are used to balance a disturbed intestinal microflora and dysfunctions of the gastrointestinal tract (GIT). They could be an effective alternative to the use of synthetic substances in nutrition and medicine. We investigated the effect of probiotics and potentiated probiotics on the productivity of laying hens. An experiment was carried out on 30 hens of the Hyssex layer hybrid starting from week 30 of laying. The hens were divided into three groups, 10 hens in each (K – control group, L – hens supplemented with probiotics and L + E – hens fed probiotics potentiated with essential oils). No statistically significant differences among the groups were observed in the quality of eggs. Biochemical determination of yolk cholesterol showed an insignificant difference after 25 days of feeding the probiotics. By day 50 of the experiment, yolk cholesterol decreased significantly (P < 0.05) in group L + E and insignificantly in group L of layers. Biochemical examination of blood serum detected an insignificant decrease in the activity of ALT, serum cholesterol and total lipids. Our results allowed us to conclude that probiotics and potentiated probiotics favourably affected the investigated hens and their products.

益生菌用于平衡受干扰的肠道微生物区系和胃肠道功能障碍（GIT）。它们可能是在营养和医学中使用合成物质的有效替代品。我们研究了益生菌和增强益生菌对蛋鸡生产力的影响。从铺设第30周开始，对30只Hyssex层杂种母鸡进行实验。将母鸡分成三组，每组10只母鸡（K-对照组，L-母鸡补充益生菌和L + E-母鸡喂养益生菌强化精油）。在卵的质量方面没有观察到组间的统计学显着差异。在喂食益生菌25天后，蛋黄胆固醇的生化测定显示出不显着的差异。到实验的第50天，L + E组的蛋黄胆固醇显着下降（P <0.05），L组中的蛋白胆固醇显着下降。血清生化检查发现ALT，血清胆固醇和总脂质活性无显着降低。我们的结果使我们得出结论，益生菌和增强的益生菌有利地影响了调查的母鸡及其产品。
