Description The present study was designed to investigate the efficacy of three estrous synchronization protocols and subsequent comparative fertility in cyclic and noncyclic cows. A total of 75(n) cows were subjected to the three estrous synchronization protocols i.e. 5 day Co-Synch+TRIU-B (T1; n=25), ovsynch (T2; n=25), heatsynch (T3; n=25). Ten cyclic cows were kept as untreated control group. Trans-rectal ultrasonography and serum progesterone analysis were done at intervals during the course of study. The estrus induction rate was 91.66%, 88%, 96% in T1, T2 and T3 groups, respectively. Expression of estrus signs was highest in heatsynch protocol group cows as compare to other groups. The conception rate was 65%, 59.09%, 50% and 70% in T1, T2, T3 and control group, respectively. The overall mean serum progesterone (P4) concentration on day 0 (initiation), on the day of prostaglandin injection, on the day of AI and on the day 21 post-AI revealed that the values were significantly (p
