Economic Impact of Double Synch Protocol in Buffaloes during Summer Season

The aim of the study was to evaluate the economic impact of Doublesynch protocol by improving fertility in postpartum buffaloes. The experiment was conducted in 200 lactating buffaloes at dairy farm, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, Punjab during summer months (April to July). The buffaloes were divided into 2 groups. The buffaloes in group I (Doublesynch group, n=100) were administered PGF2α (Cloprostenol, 500 μg i.m.) on day -2, GnRH (Buserelin acetate, 20 μg, i.m.) on day 0, a second PGF2α on day 7 and a second GnRH on day 9 (Buserelin acetate, 10 μg, i.m.). The buffaloes were inseminated twice at 14 to 16 h and 38 to 40 h following second GnRH. Buffaloes in group II (Control group, n=100) that exhibited natural estrus during the study period were inseminated at detected estrus. Pregnancy diagnosis was performed at 45 days post AI by ultrasonography. The higher (P<0.05) pregnancy rate in Doublesynch (58.0%) compared to control group (39.0%) indicated the success of Doublesynch protocol in buffaloes during summer. The service period in Doublesynch group was 12 days shorter than in control group that improved the economics of dairy farm by Rs. 3225.12/pregnancy. In conclusion, profitability in dairy farming can be enhanced through application of Doublesynch protocol in postpartum buffaloes during summer season.
