Abstract:
The present experiment was carried out to evaluate fertility response in postpartum lactating anestrous buffaloes in farm and field conditions during breeding and low breeding seasons by using synchronization protocols (Double prostaglandins, Presynch-Ovsynch, Ovsynch and CIDR-Ovsynch). The present study showed no significant difference (P>0.05) in estrus response between treatment groups, whereas significant difference (P<0.05) was observed between treatments and control group in farm and field, and significant difference (P<0.05) was observed in farm and field during breeding and low breeding seasons. Significantly (P<0.05) more number of buffaloes showed intermediate estrus during breeding and low breeding season under farm and field conditions. Overall conception rates were higher in Presynch-ovsynch (POVS) treated group during breeding and low breeding seasons under farm and field conditions, followed with Ovsynch (OVS), Double PG (DPG) and CIDR-Ovsynch (COVS) group. In conclusion, POVS hormonal protocol has been effectively improve the fertility response in sub-estrus buffaloes, whereas OVS hormonal protocol has been effectively improve the fertility response in true anestrous buffaloes in breeding and low breeding seasons.
