微囊化益生菌作用机理及其在畜禽养殖中的应用研究进展OA

Microencapsulation technology is an innovative formulation technique that encapsulates active ingredients within microcapsules using carrier materials.It has demonstrated unique advantages in the development of probiotic formulations for animal husbandry.Probiotics,as green feed additives,possess multiple beneficial functions,including regulation of gut microbiota,enhancement of immunity,and promotion of growth.However,traditional formulations face limitations,including poor acid resistance,low survival rates during gut colonization,and a propensity for activity loss,all of which restrict their application efficiency.Microencapsulation technology,by employing biocompatible encapsulation carrier materials in conjunction with processes like emulsification and spray drying,can effectively protect probiotics from degradation by gastric acid,bile salts,and other digestive fluids.This technology enables targeted delivery,controlled release,and sustained action,significantly improving the stability and bioavailability of the formulations.This article systematically analyzes the encapsulation mechanisms,the characteristics of carrier materials,and the protective mechanisms of microencapsulation technology on probiotic activity.It also reviews the application progress of microencapsulated probiotics in animal husbandry,with a focus on their effects in enhancing gut barrier function,balancing gut microbiota,boosting immune performance,improving production efficiency,and ensuring livestock product quality.The study provides theoretical support for the development of high-efficiency,stable microencapsulated probiotic formulations and promotes the large-scale application of microencapsulation technology in green animal husbandry.
