Abstract:
Postpartum lactating anestrous Ongole cows were treated with estrus and ovulation hormonal protocols Heatsynch (Group A) and G6G (Group B) and progesterone profile analysis was done following estrus induction. The mean progesterone concentration 10 days before initiation of treatment in Heatsynch treated group was 0.78±0.12 (0.3 to 1.2) ng/ml and on the treatment initiation day was 0.81±0.16 (0.7 to 1.4) ng/ml, at the time of PGF2α injection on day 7 was 1.64±0.89 (1.3 to 1.9) ng/ml and on the day of estrus was 0.62±0.60 (0.4 to 1.2) ng/ml. The mean progesterone concentration 10 days before initiation of treatment in G6G treated group was 1.16±0.15 (0.6 to 2.2) ng/ml and on the treatment initiation day was 1.26±0.14 (0.5 to 2.6) ng/ml, on the day of second PGF2α injection on day 17 was 1.28±0.52 (0.5 to 2.3) and on the day of estrus was 0.77±0.05 (0.5 to 1.3) ng/ml. Cows that had high concentration at -10 and on the day of intiation of treatment had conceived at induced estrus. The hormonal protocols (Heatsynch and G6G protocol) had significant influence on circulatory serum progesterone profiles.
