RESUMO:

In order to evaluate the effects of eCG, BE and GnRH on the follicular dynamics and luteal characteristics of lactating buffaloes (Bubalus bubalis), 40 females were submitted to an FTAI protocol. At day 0 all animals received an intravaginal P4 device, associated with 2mg of BE and 0.5mg of sodium cloprostenol. In D9, the implant was removed and 0.5mg of sodium cloprostenol was administered in all animals and 400UI of eCG in half of the animals. In the D10 (24 hours after implant removal) half of the females treated with eCG and half of the females not treated with eCG received 1,0mg of BE. In D11 the other half of the eCG treated females and the untreated females received 10μg of a GnRH analogue (buserelin acetate). In this way, the four experimental groups were constituted: C/eCG+GnRH (n= 10), S/eCG+GnRH (n= 10), C/eCG+BE (n= 10) and S/eCG+BE (n= 10). With the use of B-mode and power-Doppler ultrasonography, DFol (D9, D10 and D11), DFOV, TXFol, VFOV, %VFOV, MOV and TxOV were evaluated in follicular dynamics, in addition to DCL D18, VCL and dosages of P4 (D18) for the luteal function. Statistical analyzes were performed using the Tukey test, Kruskal-Wallis test and repeated measures ANOVA with a significance level of 5%. Significant statistical differences were found for DCL D18 with 1,78±0,12cm in the group (C/eCG+BE) and 1,62±0,11cm in the group (S/eCG+BE), in addition, in the P4 between the treatments C/eCG+GnRH (4,09±0,94 ng/mL) and S/eGC+GnRH (2,80±0,70 ng/mL). Regarding the variables evaluated by the power-Doppler mode, no statistical difference was found between the experimental groups. It was concluded that the use of BE or GnRH associated to eCG allowed efficient synchronization and induction of ovulation in lactating buffaloes submitted to an FITAI protocol, and should also take into account the cost-benefit factor favorable to the use of BE.
