Pharmacologic control of swine reproduction.
Current approaches to control fertile estrus and parturition in the pig are discussed. Techniques to induce estrus in acylic pigs (pregnant mare serum gonadotropin and human chorionic gonadotropin) to synchronize estrus in cyclic females (progestins), and to control onset of ovulation (human chorionic gonadotropin) are described. Regimens that induce parturition (prostaglandins) and precipitate farrowings at more predictable times (oxytocin) are addressed.
