Pathology and occurrence of uterine atrophy in cattle

The present investigation was carried out from May 2009 to October 2009. During this period a total number of 390 samples of female genital tract were examined from cattle of different age and breeds, of which 156 were found to have various abnormalities. Out of these, 64 samples revealed pathological lesions in the uterus, of which 5 cases (3.2%) were of atrophic uterus. Grossly, the serosal surface of uterus appeared lusterless, with comparatively hard wall. The mucosa was devoid of mucosal folds and showed numerous small, hard, closely arranged cotyledons. Microscopically, mucosa contained few small inert glands as well as cystically dilated glands lined by flat epithelium. Thick walled sclerotic endometrial vessels with reduced lumina were also noticed.
