This study aimed characterize aspects of uterine morphoechogenicity and CL, relating to the P4concentrations during the rainy and dry seasons. Nine mares were used, synchronized with two doses of 1,0 mLPGF2α and monitored by ultrasound and rectal palpation. The ecogenicity - uterine and CL - were determinedby the degree of edema and glandular organization, respectively. Had blood collected by puncturing the jugularvein for dosing P4 by ELISA. Among the mares was no difference in ovulation rate between the periods (P <0,05). As for uterine morphoechogenicity, there was no significant difference between periods (P > 0,05). Therewere differences between periods (P < 0,05) for plasma levels of P4, being higher in the rainy season.Regarding CL morphoechogenicity presented from anechoic to hyperechoic center. The changes in the uterineechogenicity and CL is the expected for the species as well as progesterone concentrations, showing nodifference between the periods.(AU)
