A description of normal ultrasonographic alternations of the uterus in the postpartum (PP) in buffaloes
is essential for the diagnosis of pathological conditions and improves the ability to differentiate puerperal
pathology from normal physiological changes. The current study aimed to characterize the
changes in uterine features assessed ultrasonographically in normal parturient Egyptian buffaloes
(n=20) during the post-calving period (Until Day 60 PP). In the current data, ultrasonographic findings
indicated that the uterine involution was completed at 4-6 weeks PP in normal calved Egyptian buffaloes.
Moreover, calving during the spring season and female new born calves were associated with
an enhanced uterine involution. Early cyclicity positively influences endometrial thickness (during early
PP), dorsal and ventral uterine curvature, and uterine lumen diameter (during late PP) as compared
with the late cyclic group. In conclusion, the uterine involution is ended by the 6th weeks PP in normal
parturient Egyptian buffaloes. Moreover, season and calves gender implicate in the changes associated
with uterine involution in buffaloes. It is extremely recommended to employ ultrasound examinations
in the dairy herd to improve the reproductive efficiency of females by reducing the days open and increasing
the number of milking animals.
