Abstract There is a proven influence of the moon on some agricultural tasks, but at level of the animáis such influence has been little analyzed. The objective of this research was the analyze of influence moon about some reproductive process in bovines. The results of the present investigation were obtained by X2 from a data set of 830 registrations of natural heat and 305 data of births, collected of some herds located in the Southern Región of Ecuador-South America. The study showed that the natural heat and the births in bovines follow a eyelieal process, having a higher incidence of these processes in the phases of first quarter and full moon, while in the waning phase, the incidence is lower. Also is noted that the mating cows in any phase, tend to calve in the two following phases and the probability of parturition in the same phase that oceurred the mating is lower. As for the synchronization of heat, the better results in the conception rate at the first service were obtained when the female bovine were synchronizing in the dark moon and first quarter phases. In conclusión have influence of the moon phases in the reproductive process analyzed, so is important it's considered for take better results.

Keywords : Moon; pregnancy; calve; reproductive efficiency; synchronization of heat.
