Effects of Environmental Stressors on Livestock

The puerperium is the period between birth and complete uterine involution, which is around 40 days postpartum (dpp) in cattle. This study evaluated the dynamics of uterine involution in 19 crossbred dairy cows, who had given one or more births. The evaluation was done by observing the vital characteristics, body score, ultrasonographic and gynecological examinations, and the odor and characteristics of vaginal secretions. These evaluations were done during eight different moments of puerperium: day 0, 3, 7, 10, 14, 21, 28, and 43. The results from this study demonstrated that there are specific differences relative to uterine involution in crossbred dairy cows at 21 and 28 dpp. Additionally, these results suggest that the diagnosis and treatment of clinical endometritis normally done by evaluating the characteristics and the odor of vaginal secretions should be revised, since spontaneous recuperation of endometritis occurred at 43 dpp.
