The purpose of this study was to evaluate the leukocyte count and the oxidative metabolism of neutrophil in Saanen goats during periods of pregnancy, parturition and postpartum. Were used 20 Saanen goats, clinically healthy and serologically negative for caprine arthritis encephalitis virus (CAEV). Blood samples were collected by jugular venipuncture 49 (M1), 42 (M2), 35 (M3), 28 (M4), 21 (M5), 14 (M6), seven (M7), three (M8) days before the parturition, on the day of birth (M9), three (M10) and seven (M11) days postpartum, for the leukocyte count, and serum for cortisol, estradiol and progesterone determination. From 28 days (M4) before parturition until seven days postpartum (M11) blood samples were collected for evaluation of oxidative metabolism of neutrophils by the nitroblue tetrazolium reduction test (NBT). The results showed that at parturition day there were an increase in cortisol and estradiol levels and a decrease in progesterone serum, neutrophilic leukocytosis and left shift slight, decrease of lymphocytes, increase in the neutrophil: lymphocyte, eosinopenia, monocytosis and basophilia. There was a neutrophilic leukocytosis and an increase in the neutrophil: lymphocyte on the seventh day postpartum. There were not significant alterations in oxidative metabolism of neutrophils during pregnancy, parturition and postpartum. It was concluded that parturition causes an elevation in cortisol and estradiol levels and a decrease in progesterone serum determining a neutrophilic leukocytosis and left shift slight, with a reduction of lymphocytes, increase in the neutrophil:lymphocyte, eosinopenia, monocytosis and basophilia. Neutrophilic leukocytosis, increase in the neutrophil: lymphocyte and fibrinogen are detected on the seventh day postpartum. Pregnancy, parturition and the postpartum do not change the oxidative metabolism of neutrophils evaluated by NBT reduction test. |
