文摘

FSH stimulation increased the number and the proportion of medium-sized follicles for OPU in non-lactating Holstein cows. The use of FSH stimulation in four or six administrations resulted in similar OPU-IVP efficacy. Cows with high follicle population have 90% increase in the number of blastocysts and tended to have lower blastocyst rate.
