Research progress on application of microecological preparation in cultivation of Litopenaeus vannamei
Microecological preparations are a new type of feed additive with the characteristics of green,ecological,non-toxic,residue free,non resistant,and wide range of action.They have the functions of regulating intestinal microbiota balance,inhibiting harmful bacterial growth,enhancing body immunity,purifying water quality,improving feed utilization rate,and promoting the growth and development of aquatic animals.They have been widely used in aquaculture.In recent years,the significant progress has been made in the application research of microecological preparation in the cultivation of Litopenaeus vannamei,especially in terms of growth performance,immune function,disease resistance,and other aspects.The article reviews the classification,mechanism of action,and application effects of microecological preparations in the cultivation of Litopenaeus vannamei.The aim is to provide a reference for the research of microecological preparation and its reasonable application in the cultivation of Litopenaeus vannamei,and further promote the efficient and healthy development of Litopenaeus vannamei culture industry.
