The objectives of the present study were to evaluate the effects of photoperiodicity, gauge (G) of ovum pick-up (OPU) needle, and two methods of follicular wave emergence on follicular turn-over, oocyte recovery (OR), quality of the oocytes (OQ), and early in-vitro developmental competence of embryos in Nili-Ravi buffaloes (n = 20). In 1 experiment, buffaloes (n = 12; 4 buffaloes/season) were randomly assigned to optimize the OPU's (n) either with 17 G or 18 G needle in one of the following seasons: 1) peak breeding season (PBS; Sep-Nov; n = 31), 2) transition breeding season (TBS; Dec-Feb; n = 32), and 3) low breeding season (LBS; Apr-June; n = 32). During 2 experiment, buffaloes (n = 8) were enrolled randomly in a 2 × 2 cross-over design to compare the two methods of wave emergence either using follicular ablation (FA; n = 4), or synchronization protocol (CIDR-EB; n = 4) during PBS. In FA method, the ovarian follicles were aspirated (week -1), and subsequently repeated OPU's (n = 55) were performed for 7 weeks. However, in CIDR-EB synchronized buffaloes, a progesterone device (CIDR) was inserted in the anterior vagina and a single dose of estradiol benzoate (2 mg) and prostaglandin (150 μg) were administered i.m. on d 1. The CIDR was removed on d 7 and repeated OPU's (n = 56) were performed. In both experiments, a 7-d resting period was provided between each OPU session. Data on the follicular turn-over, OR, OQ, and early stages of embryonic development were analyzed with mixed models using the PROC MIXED and GLIMMIX procedures of SAS. Results revealed that the number of medium sized follicles (LSM ± SEM) and rate of OR (%) were greater (P < 0.05) during PBS (2.76 ± 0.40; 61%) and TBS (1.73 ± 0.30; 54%) as compared to LBS (0.68 ± 0.30; 31%) in buffaloes, respectively. The OR rate was also greater (P < 0.05) using 17 G as opposed to 18 G needle (62% vs. 35%), however, there was no effect (P > 0.05) of season and G of needle on OQ in buffaloes. In experiment 2, the number of small (3.50 ± 0.63 vs.2.69 ± 0.60) sized follicles was higher (P < 0.05) in FA, whereas, medium (1.13 ± 0.45 vs. 1.59 ± 0.45) sized follicles were greater (P < 0.05) in CIDR-EB synchronized buffaloes. The OR rate (67% vs. 53%), and OQ (Grade I_+_II; 15% vs. 16% and Grade III_+_IV; 85% vs. 84%), remained similar (P > 0.05) in FA and CIDR-EB treated buffaloes, respectively. Similarly, rates of in-vitro maturation (66% vs. 59%), cleavage (42% vs. 53%), 4-cell (27% vs. 32%), 8-cell staged embryos (23% vs. 25%), and morula (13% vs. 8%) did not differ (P > 0.05) between FA and CIDR-EB methods of follicular wave emergence, respectively. Taken together, it is concluded that peak or transition breeding seasons are suitable to perform OPU using 17 G needle for maximum follicular turn-over, and OR in buffaloes. However, the two fundamental methods of synchronization of wave emergence resulted in similar efficiency for OPU derived in-vitro embryo production in Nili-Ravi buffaloes.
