Abstract:
Fertility response following fixed time insemination was studied in 48 Sirohi goats, randomly divided into 4 groups, each comprising 12 animals (n=12). Animals of group l received Ovsynch protocol; in group II (IMOvP-1), treatment was similar to group-I plus additional 3-doses of long-acting insulin @ 0.14 IU/ kg b. wt. subcutaneously on day 4, 5 and 6. In group-III (IMOvP-2), treatment was similar to group-I plus 3 additional doses of long-acting insulin @ 0.14 IU/ kg b. wt. subcutaneous on day 8, 9 and 10. However, animals of group–IV were kept as control. All the animals were inseminated once at fixed time i.e. 16 hrs after second GnRH injection using fresh semen and pregnancy was confirmed by ultrasonography at 30 days post insemination.
The results of fertility response using fixed time insemination protocol in goat shows significantly higher synchronization of oestrus in treatment groups (83.33%-GI; 91.66%-GII and 100%-GIII) as compared to control group (8.33%-GIV). The conception rate at fixed time insemination was also recorded higher in treatment groups (58.33%-GI, 83.33%-GII and G-III) as compared to control group (8.33%-GIV). The analysis of results revealed higher conception rate in insulin modified Ovsynch protocols where the intensity of oestrus was better during fixed time insemination.
