Ovarian abnormalities impair the development of follicles and, subsequently, estrus cycles in buffaloes. In order to compare and systematically document the various conditions affecting the ovary, 1000 buffalo carcasses from various slaughter houses located at Puducherry and Chennai were examined. Both right and left ovaries were collected from 200 (20%) buffaloes, where one or both the ovaries were apparently abnormal and were subjected to detailed examinations for various conditions/affections. The cystic ovarian disease (COD) which includes follicular cysts (50/200 cases, 25%), luteal cyst (3/200 cases, 1.5%), cystic corpus luteum (5/200 cases, 2.5%), cystic rete ovarii (10/200 cases, 5%), inclusion cysts (2/200 cases, 1%) and parovarian cyst (3/200 cases, 1.5%). Out of 6 various cystic conditions recorded in this study, the major finding was follicular cyst (25%) followed by cystic rete ovarii (5%).
The study highlighted the importance of knowledge on genital diseases in buffaloes because of its intimate relationship with animal reproductivity and productivity. Pathological conditions affecting the ovaries leading to ovarian dysfunction are the highest in order of magnitude among the abnormalities of reproductive organs of buffaloes. Inactive ovaries lead to acyclicity and anestrus causing infertility in buffaloes. This phenomenon is attributed to multiple factors including malnutrition, parasitism, improper hygiene and pollution. Post slaughter examination of the ovaries provides more specific information on the tissue change which might not have been clinically detected.
