Abstract:

The colostrum of ruminants encompasses abundant bioactive components, of which microRNAs are kind of non-coding RNAs that can regulate gene expression at the post-transcriptional level and play important roles in regulating development of the mother's mammary gland and gastrointestinal tract of young ruminants. In recent years, studies on the profile and function of microRNAs derived from ruminant colostrum have attracted attention. In this review, the source, composition, influencing factors, and function of microRNA in ruminant colostrum as well as the limitations of current studies and future research directions were summarized, with an aim to provide theoretical support for the production of high-quality colostrum and improve integrated mother-neonate cultivation level.

Key words: ruminant, colostrum, microRNA, extracellular vesicles
