Assessment of two Superovulation Protocols for Embryo Production in Holstein Cows
The aim of this paper was to compare the effects of two superovulation protocols (synchronization of the follicular wave (SFW), and natural estrus (NE) induction of embryos produced for transference in Holstein cows. Twenty cows were chosen as donors, with a body condition (BC) of 2.75-3.5; 40-60 months old; 1-2 previous gestation services, and without reproductive problems. Two superovulation protocols were applied: SFW and NE. SFW was not observed to produce more embryos than NE in the blastocysts and morula stages.
