ABSTRACT
The aim of this study was to evaluate the influence of lunar phases in Dorper sheep, according to theproportion of births (single double). Twenty were used two sheep from a breeding season. For the evaluation oflunar phases sheep were grouped proportionally according to the type of delivery (single double). The analysisof the types of delivery were obtained according to the moon phases in place by the Brazilian NationalObservatory, being considered corresponding to the lunar phase where the maximum headquarters was up totwo days before and after the date of interest after being compared by the test chi-square test (P <0.05). It wasfound that there was a greater proportion of births in the crescent moon (P <0.05) compared to other lunarphases. The conclusion of this research that the crescent moon of the lunar phases, seems to affect the types ofdelivery of Dorper sheep.(AU)
