Abstract

The aim of this study was to describe aspects of the parturition and uterine involution in native sheep from Brazilian Pantanal. Fifty-seven pluriparous ewes were used in this study. At parturition, the placenta expulsion (h), weight (g), total diameter of cotyledons, sex and weight of newborn, and single or twin parturition were evaluated. The uterine involution was evaluated by leucocytes profile, desquamation cells (cervix-uterine smears) and transrectal ultrasonography at 1, 7, 14, 21 and 28 days post-partum. The weight of the placenta and total of cotyledons were higher (P<0.05) in female lambs from single and twin parturition. Placental expulsion time and cotyledons diameter were not different (P>0.05) between sex and parturition classification. The total of neutrophils in twin parturitions were higher in days 1, 7 and 14 postpartum (78.5±9.5; 58.5±9.6 and 31.9±9.8, respectively). Macrophages were different (P<0.05) at 1 and 14 days postpartum in ewes with twin parturition (12.5±1.6 and 6.7±1.6, respectively). The regression analysis model revealed a quadratic curve estimation (P<0.001) to the diameter, area and uterine volume considering all postpartum period. In conclusion, the parturition characteristics are similar to other breeds. Leukocytary profile and the transrectal ultrasonography exam suggest that the uterine involution in native sheep of Brazilian Pantanal varies among 14 and 21 days postpartum.
