A field-oriented study was conducted to have an insight of various etiological factors of anestrus and their occurrence in cattle and buffalo of Malwa region of Punjab. A total of 116 animals (Cattle-58; Buffalo-58) with the history of anestrus were subjected to gynaecological examination and diagnosis was made on the basis of history, clinical signs, rectal findings, body condition scores (BCS) and plasma progesterone profiles. Repeated clinico-gynaecological examinations were made and plasma samples taken at 3-5 days interval for 21 days. Out of the total 58 cows presented, 37 (63.79%) were in true anestrus, 6 (10.34%) in subestrus, 1 (1.72%) had persistent corpus luteum and 14 (24.13%) were found pregnant, whereas the number of buffaloes in the respective categories were 12 (20.69%), 15 (25.86%), 2 (3.45%) and 29 (50.00%). The higher number of buffaloes diagnosed to have subestrus reflects the inadequacy of farming community to detect estrus properly as they consider the vocalization as sole criteria of estrus. Also the percentage of animals (both cattle and buffalo) diagnosed as pregnant (although presented to be of anestrus) point towards the poor managerial skills of the fanners. Most of cows [20/37 (54.05%)] and buffaloes [10/12 (83.33%)] in true anestrus were postpubertal heifers having a BCS ranging from 2.0-2.5.
