Reproductive Physiology and Anatomy of the SowReproductive Physiology and Anatomy of the Sow

Sexual Behavior in Swine. Length of estrus or heat is variable and may last only 12 hours in gilts or up to 60 hours or more in sows. Since the actual time of the onset of estrus is rarely known, it is recommended that a female receive at least two matings during estrus.

Two services as compared to one may increase conception rate and litter size by approximately 10%.. After ovulation, the follicular structures are transformed into corpora lutea. Beginning on about day 1 to 2 after mating, they produce and release the hormone, progesterone which is responsible for maintaining pregnancy. If conception does not occur, prostaglandin (F2a) is secreted by the uterus causing the corpora lutea to ...
