Abstract: With the development of global animal husbandry, the restrictions on the use of feed antibiotics have gradually increased. Microecological preparations can replace antibiotics in livestock and poultry production due to their green, safe, highly efficient, non-toxic, and low drug-resistance-inducing characteristics. Microecological preparations can promote the development of the animal immune system and intestinal tract, improve the body's immune performance, and enhance the mucosal physical barrier. They also possess multiple functions of regulating the composition and activity of intestinal microbiota, maintaining intestinal microbiota balance, improving digestive function, enhancing feed digestibility and utilization efficiency, promoting growth and development, and alleviating stress. The period from birth to weaning is a crucial period in the life cycle of calves. The health status of calves at this stage is directly related to their adult productivity, overall health and breeding efficiency. Based on this, with summarizing the different types and functions of microecological preparations, this paper reviews the regulatory mechanisms of microecological preparations in the growth and development of calves from the aspects of enhancing growth performance, improving body immunity and regulating intestinal microbiota balance and health, aiming to promote microecological preparations to play a greater role in advancing the development of calf breeding industry and accelerating the green transformation of animal husbandry.
