Abstract: Buffalo is one of the dairy livestock breeds in China, which has strong adaptability to high temperature, humidity, and rough feeding, and the buffalo milk has high nutrition and economic value, so it is known as the "king of milk". However, dairy buffaloes have late sexual maturity, unperceived estrus symptoms, and are susceptible to environmental factors, thus resulting in low reproductive efficiency, which in turn causes waste of workforce and economic losses. Therefore, it is important for dairy buffalo production to know effective estrus identification method and thus determine optimal breeding time. In this paper, we summarized the advantages and disadvantages of manual and automated methods for the identification of various estrus stages in dairy buffaloes, reviewed relevant studies on the identification of estrus in dairy buffaloes by blood, urine, saliva, cervical-vaginal fluid (CVF) and feces, and discussed the possibility of developing new methods for estrus identification in dairy buffaloes with omics technology by referring to relevant reports, aiming to provide reference for the development of new methods for estrus identification in dairy buffaloes.

Key words: dairy buffalo, estrus identification, blood, salivary, reproductive performance
