Abstract:

The objective of this study was to compare the conception rate for fixed-timed artificial insemination (FTAI) and observed heat artificial insemination (HAI) prior to the scheduled FTAI in Doublesynch and Estra doublesynch synchronization protocols as well as HAI in mineral supplemented cyclic non breeding cattles (RB). A total of 80 animals (40 RB cows, 40 RB heifers) were selected and divided into four groups each constituting 20 RB animals (10 heifers and 10 cows) in which different therapeutic regimen was followed along with supplementation of area specific mineral mixture (ASMM) for 60 days. Group I animals served as control which thrived on regular farmer practice. Group II animals were provided with only mineral supplementation (ASMM) for 60 days. Group III animals were provided with mineral supplementation along with the use of double synch protocol for estrous synchronization. Group IV animals were provided with mineral supplementation along with the use of Estra double synch protocol for estrous synchronization. Fixed time artificial insemination was performed in group III and IV whereas in group I and II, artificial insemination was done on observed estrus. Pregnancy diagnosis was done 45-60 days following artificial insemination by rectal palpation. Results revealed significant improvement in conception rate in treatment groups as compared to control group. The conception rate was highest in group IV (70%) followed by group III (65%), group II (40%) and 15 percent in group I (control group). Comparison of different treatment protocol suggested that Estra doublesynch protocol fared better than other treatment schedule in establishment of pregnancy in repeat breeding cows and heifers.
