Description The study was conducted to document the incidence and nature of oestrus like signs and follicular biometry during the lunar and peri-lunar days in crossbred cattle. Crossbred cattle (n = 678) which were reported to be with oestrus like signs on lunar days (full moon day and new moon day) and peri-lunar days were subjected for the investigation. Only 60.6 per cent of the animals during the study period were in actual oestrus. The remaining animals (39.4%) were found to be in various reproductive statuses viz., pregnancy (17.7%), mid-cycle oestrum (6.9%) and without any oestrus characteristics (14.8 %). The diameter of the dominant follicle in cattle with oestrus signs during lunar days (10.4 ± 0.2 mm) was significantly (P < 0.05) smaller than cattle in actual oestrus during normal days (12.2 ± 0.5 mm). Exhibition of oestrous signs with smaller follicular diameter indicated the probable chances of lunar influence on the follicular dynamics, steroidogenesis and reproductive characters in cattle.
