Observations regarding ultrasound disgnosis of anestrus syndrome in dairy cattle

Abstract

Visual transrectal ultrasonography is one of the most effective tools to study ovaries and uterine structures in cows. This study was conducted within a dairy cattle farm and aimed to highlight the importance of ultrasound examination for diagnosis of uterine and ovarian disorders in dairy cattle. During the study regarding ultrasound diagnosis of anestrus syndrome in dairy cattle, several types of genital pathologies were recorded. Thus, of all recorded uterine and ovarian disorders, 35 cases of endometritis (19.1%), 12 cases of acute metritis (6.5%), 26 cows with follicular cysts (14.2%), 21 cows with luteal cysts (11.5%), 42 cases of persistent corpus luteum (23%), 25 cows with ovarian inactivity (13.7%) and 22 cows with silent estrus (12%), were diagnosed. Reproductive tract ultrasound examination provides a more accurate identification and differentiation of ovarian and uterine disorders type, having a higher sensitivity and specificity than manual palpation, improving thus the diagnosis precision.
