ABSTRACT
The objective of the experiment was to verify, through ultrasonography, the follicular activity of ostriches in different seasons of the year, correlating them with photoperiod, number of rainy days in each month and egg laying. Eight females were evaluated monthly, during 12 consecutive months in an ostrich farm located in the Center-West of Minas Gerais, Brazil. It was found that the time of the year for egg laying lasts for eight months, from June to January. The egg laying was positively correlated (r = 0.48; P<0.01) with photoperiod. However, there was no correlation between the egg laying and the follicular activity with the amount of rain. Considering the technique adopted, the right antimere offered better ultrasonographic access. The method was efficient for ovary follicular evaluation in the ostrich, offering adequate subsidies for the evaluation of the reproductive activity of the female.
