益生菌是能够定殖宿主消化系统的有益细菌，增加天然植物群并防止病原生物体的定殖，从而确保饲料的最佳效用。然而，商业益生菌往往不符合预期的标准，这些菌株的效力的可行性仍然值得怀疑。另一个主要问题已经被强调与抗生素抗性益生菌的应用有关，抗生素抗性基因可以在生物体之间转移。近年来，微生物代谢产物作为饲料添加剂以替代饲用抗生素已得到广泛研究。各组间的采食量、蛋重、蛋重和饲料转化率差异不显著（P > 0.05）。从28周龄开始，与其他组相比，COM 456组的粪便pH值显着降低（P < 0.05）。从30周龄开始，COM 456的乳酸菌计数水平显著高于（P < 0.05），COM 246和COM 345分别在32和34周龄时其次。从30周龄开始，观察到COM 246和COM 456中粪便肠杆菌科细菌的显著减少（P < 0.05）。血浆胆固醇和蛋黄胆固醇水平在COM456中最低（P < 0.05），其次是COM345和COM246。处理组之间的蛋黄重量无显著差异。与对照组相比，添加代谢物组合的处理组中C18：3、C20：2和C22：6的含量显著升高（P < 0.05）。本研究证明了代谢物组合补充剂在产蛋鸡中的积极作用。在添加代谢物组合的所有处理中均观察到母鸡日产蛋量增加。此外，代谢产物组合COM 456降低了粪便pH值和粪便肠杆菌科细菌数量，改善了粪便乳酸菌，降低了血浆和蛋黄胆固醇，并改善了粪便挥发性脂肪酸含量。生物后代谢物组合可用作替代饲料添加剂，以实现高生产率和更好的动物健康，同时减少常规化学治疗剂如饲料中抗菌剂的使用。
Probiotics are beneficial bacteria that are able to colonize the host digestive system, increasing the natural flora and preventing colonization of pathogenic organisms and thus, securing optimal utility of the feed. However, commercial probiotic often do not meet the expected standards and the viability of the efficacy of these strains remains questionable. Another major issue has been highlighted in relation to the application of antibiotic resistant probiotics, the antibiotic resistant gene can be transferred between organisms. Recently, postbiotic metabolites produced from microbes have been extensively studied as feed additive in order to substitute in-feed antibiotics. No significant difference (P > 0.05) was found among the treatment groups on overall feed intake, egg weight, egg mass and feed conversion efficiency. COM456 had a significant reduction (P < 0.05) in faecal pH compared to the other groups at 28 weeks of age onwards. COM456 had significant higher (P < 0.05) level of lactic acid bacteria counts from 30 weeks of age onwards, followed by COM246 and COM345 at 32 and 34 weeks of age, respectively. Significant reduction of faecal Enterobacteriaceae (P < 0.05) were observed in COM246 and COM456 from 30 weeks of age onwards. The lowest levels (P < 0.05) of plasma and egg yolk cholesterol were observed in COM456, followed by COM345 and COM246. There was no significant difference in terms of yolk weight between the treatment groups. Significant higher (P < 0.05) content of C18:3, C20:2 and C22:6 were found in treatments supplemented with metabolite combinations as compared with the control group. The present study demonstrated the positive effects of metabolite combinations supplementation in laying hens. Increase in hen-day egg production was observed in all treatments supplemented with metabolite combinations. In addition, the metabolite combinations, COM456 had reduced the faecal pH and faecal Enterobacteriaceae population, improved the faecal lactic acid bacteria, reduced the plasma and yolk cholesterol and improved the faecal volatile fatty acids content. Postbiotic metabolite combinations can be used as an alternative feed additive to achieve high productivity and better animal health while reducing the use of conventional chemotherapeutic agents such as in-feed antimicrobials.
