Treatment of postpartum lactating anestrous Ongole cows (n=8) using G6G hormonal protocol was undertaken. Following the treatment, 7 cows exhibited estrus after second PGF2α injection. The estrus detection rate was 87.5 (7/8) per cent. Mean time to onset of estrus was observed as 34.3±4.08 h. The per cent of cows that showed intense, intermediate and weak estrus were 42.86, 57.14 and 0.0 per cent. The peak estrus synchrony with highest number of animals exhibiting estrus between 24 to 48 h was 57.14 (4/7) per cent. The artificial insemination submission rate was 87.5 (7/8) per cent. The conception rate at induced estrus in the present study for G6G treatment group was 62.5 (5/8) per cent. In the present study, overall conception rate among the postpartum lactating anestrous Ongole cows was higher with 75.0 (6/8) per cent in G6G group compared to 25.0 (2/8) per cent in the control group. The results of the present study with inseminations at induced estrus in postpartum lactating anestrous Ongole cows appears to be an effective method of managing fertility by using G6G protocol.
