abstract
The present study was done to observe the follicular population with respect to three different seasons viz., winter, summer and rainy in sheep ovaries. Six hundred ovaries were collected in each season and the numbers of surface follicles were recorded. Among the three seasons, number of small, medium, large size and total surface follicles in each ovary was high (P<0.05) during winter season and significantly lower in summer compared to other season. The mean number of small surface follicles were statistically higher (P<0.05) in all the three seasons. It was evident from the result that in winter season number of total surface follicles in sheep ovaries was higher compared to summer and rainy season.
