Objective: The research was accomplished to appraise the productive and reproductive physiology of repeat breeder (RB) cows and compare to normal cyclic (NC) cows. Methodology: A total of 366 RB cows were surveyed from 1859 crossbred and indigenous cows using a questionnaire upon positive sampling of RB syndrome in dairy farms throughout the selected areas of Bangladesh. Out of 366 RB cows, 170 were randomly selected, which were at day 0 of estrous cycle. To compare the physiological characteristics, 170 NC cows at day 0 of estrous cycle were also selected randomly. Results: Results showed that age, BCS, and parity were higher in RB cows than NC cows. Survey on productive characteristics illustrated that milk production (P [J Adv Vet Anim Res 2018; 5(3.000): 324-331]
