The paper tried to make a connection between the lunar phases and the bovine conception rate both in dairy and beef farms. The goal of the study was to improve the efficiency of farming by sparing semen doses used for a successful insemination. 1481 pregnant cattle from seven different areas of Romania were the subject of this study. New moon and waxing crescent vs. full moon and waning crescent were associated with the insemination process. In one farm hormonal timing was used for inducing heats. In the others farmyards the oestrus was marked by spontaneous behaviour changing. The results confirmed a small influence of the lunar phases on the conception rate. The score was tight proportionally with the number of subjects. However the full moon offered a higher number of gestations than the new moon. The cows with hormonal timing heats offered a better connection between the lunar phase and fertility. Further studies could be done in this direction.
