Effects of synthetized porcine follicle-stimulating hormone and synthetized human chorionic gonadotropin on reproductive efficiency in pigs.

ABSTRACT: This study aimed to evaluate the application of synthetized porcine follicle-stimulating hormone (spFSH) in combination with synthetized human chorionic gonadotropin (shCG) in inducing puberty in gilts, promoting estrus and ovulation in multiparous sows, and improving reproductive performance. In gilts, treatment with 30 µg spFSH + 150 IU shCG advanced the onset of puberty to 160 ~ 175 days of age in 76.62% of gilts, with a significantly lower incidence of ovarian cysts compared to PMSG and PG600. Hormonal profiling demonstrated that the applied protocol successfully induced endocrine maturation in gilts to levels consistent with those characteristic of natural puberty. In multiparous sows, the estrus-inducing effect of 30 µg spFSH + 150 IU shCG was comparable to PMSG and PG600 (400 IU PMS
