The objective of this study was to evaluate the effect of the synchronization method of follicular wave on superovulatory response of bovine embryo donors. For this, seven Girolando cows and five Girolando heifers previously selected (depending on the reproductive history, sanitary conditions, nutritional and reproductive tract without anatomical abnormalities) were randomly assigned to three treatments according to the synchronization of follicular wave before the superovulation: i) synchronization with GnRH ii) synchronization with progestagen implant and application of estradiol benzoate iii) without synchronization (based on estrus detection - Control Group). After submitted to the treatment for synchronization of follicular wave, the donors were superovulated with eight decreasing FSH doses, applied twice daily by deep intramuscular injection (IM) with intervals of 12 hours for each application, with a total dose of 133 mg for each animal. The first insemination was conducted 12 hours after application of ovulation inducer (GnRH) and the second insemination conducted 12 hours after the first. The superovulatory response was measured with an ultrasound device (MINDRAY D2200 VET) to quantify the number of corpus luteum present in the ovaries on the day of embryo flushing and also assessed the number and quality of embryos recovered. It was observed that animal category and crossbred influenced the superovulatory response (p <0.05). The heifers showed a higher response to superovulatory treatment (100% of response in all treatments) when compared to cows had showed 85.7%, 57.1% and 57.1% of superovulatory response to estrus based group, GnRH and P4+EB, respectively. The genetic group (crossbred) also showed influence on superovulatory response (p <0.05) since the 3/8 animals responded better than 3/4animals. The treatments for follicular wave emergence synchronization did not show differences for superovulatory response (p>0.05), recovered structures and viable structures. So, we conclude that the treatments for follicular wave synchronization with GnRH or P4+BE can be used in Girolando donors with same efficiency of estrus based group. Besides, we conclude also that Girolando heifers have better superovulatory response than cows as well as 3/8 crossbred donors. === Embora a transfer?ncia de embri?es bovinos seja uma t?cnica amplamente empregada em todo o mundo, a variabilidade da resposta de doadoras ao tratamento superovulat?rio ainda ? uma importante limita??o.

Para tanto, sete vacas e cinco novilhas, previamente selecionadas (em fun??o do hist?rico reprodutivo, condi??es sanit?ria, nutricional e trato reprodutivo sem anormalidades anat?micas) foram aleatoriamente distribu?das em tr?s tratamentos de acordo com o m?todo de sincroniza??o da onda folicular previamente ? superovula??o: i) sincroniza??o com GnRH; ii) sincroniza??o com implante de progest?geno e aplica??o de Benzoato de Estradiol; iii) sem sincroniza??o (observa??o do cio base - Grupo Controle). Depois de submetidas ao tratamento para sincroniza??o da onda folicular, as doadoras foram superovuladas com oito subdoses decrescentes de FSH, aplicadas duas vezes ao dia, por via intramuscular profunda (IM), com intervalos de 12 horas a cada aplica??o, somando 133 mg por animal. A primeira insemina??o foi realizada 12 horas ap?s a aplica??o do indutor da ovula??o (GnRH) e a segunda insemina??o realizada 12 horas ap?s a primeira. A resposta superovulat?ria foi avaliada com auxilio de um aparelho de ultrassom (MINDRAY D2200 VET) para quantificar o n?mero de corpos l?teos presentes nos ov?rios no dia da coleta assim como pelo n?mero e qualidade dos embri?es recuperados. Foi observado que a categoria animal e o grau de sangue influenciaram a resposta superovulat?ria (p<0.05). As novilhas apresentaram uma maior resposta ao tratamento superovulat?rio (100% de resposta em todos os tratamentos) quando comparadas ?s vacas que apresentaram 85,7%, 57,1% e 57,1% de resposta superovulat?ria para os grupos cio base, GnRH e P4+BE, respectivamente. O grupo gen?tico (grau de sangue) tamb?m mostrou influ?ncia na resposta superovulat?ria (p<0.05) sendo que os animais 3/8 responderam melhor ao tratamento superovulat?rio do que os animais 3/4. Os tratamentos de sincroniza??o da emerg?ncia da onda folicular n?o apresentaram diferen?as na resposta superovulat?ria (p>0.05), nas estruturas recuperadas e nas estruturas vi?veis. Desta forma, conclui-se que os tratamentos de sincroniza??o da onda folicular com GnRH ou com P4+BE podem ser utilizados em doadoras Girolando com a mesma efici?ncia do cio base. Al?m disso, conclui-se tamb?m que novilhas Girolando respondem melhor ao tratamento superovulat?rio do que vacas assim como as doadoras de grau de sangue 3/8 quando comparadas as 3/4.
