‘Doka’ is a temporary teat engorgement phenomenon lasting for 3 to 5 days before the onset of the estrus period in cyclic and acyclic Murrah heifers. It is commonly observed by villagers in Haryana as an indicator of the initiation of cyclic reproductive activity or estrus in buffaloes. The present study was conducted to observe the morphological changes in the teat and udder during and after ‘Doka’ in Murrah buffaloes. Udder morphology was studied in thirty-five animals, which were categorized into two groups: Group I - cyclic ‘Doka’ (n=14) and Group II - cyclic without ‘Doka’ (n=21). Additionally, both udder and teat measurements were studied in forty-six animals, further divided into four categories: Group I (n=19) - cyclic ‘Doka’, Group II (n=14) - cyclic without ‘Doka’, Group III (n=6) - acyclic ‘Doka’, and Group IV (n=7) - acyclic without ‘Doka’. Cyclic ‘Doka’ animals exhibited a bowl-shaped udder, cylindrical teats, and fused quarters. During ‘Doka’, cyclic ‘Doka’ (7.41±0.23 inches) and acyclic ‘Doka’ (7.30±0.79 inches) animals showed significantly greater udder depth compared to acyclic animals without ‘Doka’ (7.41±0.23 inches). The teat length of fore and rear teats in cyclic ‘Doka’ animals was non-significantly (p<0.05) higher during the ‘Doka’ stage compared to the post-‘Doka’ stage. Rear teat diameter in acyclic ‘Doka’ animals (37.73±3.93 mm) was significantly (p<0.05) larger than that in acyclic animals without ‘Doka’ (24.74±2.16 mm).Therefore, it can be concluded that udder and teat morphological changes during ‘Doka’ can serve as a useful tool for estrus detection in Murrah buffaloes.
