“…In Mithun, female and male reproductive physiology has been studied in detail (Dhali et al, 2006; Perumal, De, et al, 2021). The length of the estrous cycle is in the range of 20–25 days with a longer duration of oestrus (50–67 h) and no distinct visible or behavioural signs of estrus (silent estrus) (Dhali et al, 2006; Ramesh et al, 2022). A recent study on follicular dynamics and hormonal profiles revealed that Mithun cows exhibit two, three and four follicular waves with a preponderance of three follicular waves (Ramesh et al, 2022).…”
