Abstract
There are some systems in order to synchronize oestrus in lactating does. Among them, PMSG and �bioestimulation� methods are mostly used in farms. In the present work, we used adult does, with more than seven parturitions and inseminated after four different synchronization treatments: control, bioestimulation 48h (doe-litter separation 48h before AI), bioestimulation 24h and PMSG (25 UI 48 h before AI). At the end of experiment period, does were killed and their ovaries and uterus removed to microscopy analysis. Results showed no differences in total number of ovarian follicles, hemorragic follicles, ovary and uterus size and weight among the used treatments. In conclusion, the different methods of estrous synchronization don�t alter the ovarian physiology in these adult does.
