Abstract

The aim of the present study was to evaluate some reproductive characteristics such as uterine involution, ovarian activity and first estrus after parturition, and reproductive disorders in buffaloes reared in the mixed system (floodplain and land / artificial pasture) in an experimental farm of  Belém, Pará State, Brazil. A total of 62 female buffaloes and 167 postpartum periods were evaluated between 2002 to 2005 through gynecological and ultrasound examination. Animals were kept on artificial pasture during the rainy season (January-June) whereas on the floodplain areas with excellent availability of pasture during the dry season (July-December). The resumption of ovarian activity, verified by visual observation of the first estrus, was in average 47.06 ± 25.66 days, while the uterine involution verified by rectal palpation and ultrasound examination was 27.5 ± 7.77 days. The number of cases of abortion, retained placenta and embryonic death were 10 (5.90%), 13 (7.78%) and 14 (8.38%) cases, respectively, while the number of cases of uterine infection was 18 (10.7%). Regarding nonfunctional ovaries, 26 (15.56%) cases were found and two (1.19%) cases of ovarian hypoplasia, three (1.79%) cases of ovarian cysts and two (1.19%) cases of salpingitis were observed.
