Ovaries collected from a total of 35 Meishan gilts of various ages were morphologically and histologically examined. Vesicular follicles were first observed in ovarian sections at 45 d of age. Simultaneously, protruding follicles appeared on the surface of the ovaries, and then ovarian weight increased rapidly with an increasing number of protruding follicles. About half of the gilts between 75 and 90 d of age had ovaries with corpora lutea, indicating that some of them had started estrous cycles before reaching 75 d of age. In Meishan gilts treated with exogenous gonadotropins, ovaries were stimulated as early as 45 d of age. These results suggest that the precocity of Meishan gilts may include the development of vesicular follicles in the ovaries at an early age.
