Insemination and Fertilization Sperm are typically deposited into the reproductive tract near the junction of the cervix and uterus. Although much of the inseminate enters the uterus, there is a significant back-flow loss of semen volume which occurs over the next several hours after insemination. A basic understanding of the anatomical and physiological function of the female pig reproductive system can aid producers in anticipating and troubleshooting reproductive problems, and in facilitating decisions which impact performance of the breeding herd.A well-fed female pig can give birth to at least 10 piglets from each pregnancy and can deliver 2 litters per year. A pig’s breeding period can be any time of the year, however, pigs can become infertile in the warmer months. Female pigs that are healthy and well-bred can give birth safely twice a year.

How do pigs sexually reproduce?
Male pigs, or boars, become sexually active once they are 8 to 10 months old. During their productive months sows enter into a phase called estrus, or “heat,” every 21 days when they are not pregnant, sending signals to the boar that they are ready and able to mate.
How do pigs mate?
In hand mating, the female is usually mated two or three times during estrus, with the first service on the first day of standing estrus, and subsequent matings at 24-hour intervals; confirmed matings should be recorded. Many commercial producers breed the sow or gilt once daily as long as she will accept the boar.
What is the process of a female pig giving birth?
Gently rubbing the udder will make the sow relax and lie on her side in the position to give birth. Farrowing is a natural process and the sow will usually need no help. Once the first piglet is born the others, and the afterbirth, will quickly follow. Farrowing should be completed within 2 to 3 hours.
Does a pig reproduce sexually or asexually?

Why study the female pig reproductive system?
A basic understanding of the anatomical and physiological function of the female pig reproductive system can aid producers in anticipating and troubleshooting reproductive problems, and in facilitating decisions which impact performance of the breeding herd.
What is the external genitalia of a female pig?
The external genitalia of the female pig is composed of some connective and fatty tissues. The vulva is endowed with blood vessels and in gilts the vulva is often observed to swell and change color near the time of estrus. This swelling and color change are not as evident in sows, and color changes are not observable in dark skinned pigs.
How many times a year can a pig give birth?
Female pigs can give birth twice a year. Young female hogs go into heat when it is time for them to mate. According to Mother Earth News, in domestic mating on farms, male partners can mate with between 12 to 50 sows in stalls.
