Two important factors affect in vivo and in vitro embryo production in cattle: the intrinsic number of antral follicles in donors and the stage of follicular development at the beginning of treatments. Antral follicle population can be predicted by an ultrasound examination or the measurement of plasma AMH concentrations, but little can be done to modify it. Although embryo production can be increased by stimulating follicle growth with gonadotropins, simplified treatments are required to facilitate on-farm applications. The objective of this presentation is to describe simplified protocols for superstimulating donors and to propose alternatives by which the two embryo technologies can be applied in the same donor at the same time.
