Preovulatory follicle dynamics and ovulatory efficiency in sows with thrifty genotype and leptin resistance due to leptin receptor gene polymorphisms (Iberian pig)

Research highlights ► This study is the first describing follicle dynamics of obese sows by ultrasonography. ► Follicular turnover and ovulation rate are not limiting prolificacy in obese pigs. ► A lower prolificacy may be more likely determined by a lower embryo survival.
