| dc.description.abstract | In the present study, treatment of postpartum lactating anestrous Ongole cows (Bos indicus) using Heatsynch and G6G hormonal protocols and their influence on fertility was studied. The mean level of PCV is statistically significant (P<0.05) on the day 0 and on the day of induced estrus. The total serum cholesterol, glucose and protein profiles varied non-significantly between conceived and non-conceived Ongole cows, in both the treatments. The mineral profile did not reveal significant variations (P>0.05) in serum calcium, phosphorus, iron, copper and zinc concentrations of Ongole cows between periods of the treatments with Heatsynch and G6G protocols. The estrus detection rate was 75.0 (6/8), and 87.5 (7/8) per cent in Heatsynch (Group A) and G6G (Group B) groups. Analysis of data of onset of estrus revealed significant difference (P<0.05) between two treatment groups. Heatsynch treated group showed intense to weak estrus signs, while the G6G treated group showed intense to intermediate estrus signs. Peak estrus synchrony with highest number of animals exhibiting estrus between 48 to 72 h with 4/6 in Heatsynch group and between 24 to 48 h with 4/7 in G6G group was observed. The artificial insemination submission rate was 75.0 (6/8) and 87.5 (7/8) per cent in Heatsynch and G6G groups, respectively. The conception rate at induced estrus with Heatsynch treatment was 66.67 (4/6), and with G6G treatment it was 71.43 (5/7) per cent. Overall conception rate among the postpartum lactating anestrous Ongole cows treated was higher with 85.71 (6/7) per cent in G6G (Group B) followed by 83.33 (5/6) per cent in Heatsynch (Group A). During this treatment period in the control group, only 37.5 (3/8) and 25.0 (2/8) per cent anestrous Ongole cows exhibited estrus and conceived, respectively. The results of present study, with inseminations at induced estrus appears as an effective way of managing reproduction in postpartum lactating anestrous Ongole cows using Heat synch and G6G protocols which revealed acceptable estrus response and conception rates. | en_US |
