Here's what to look for:
* Vulva: Female pigs have a clearly defined vulva, a slit-like opening located just behind the anus.
* Udder: Female pigs have teats or nipples located along the belly, which become more prominent as they mature.
* Scrotum: Male pigs have a scrotum, which is a sac that holds the testicles. This is a clear indicator of a male pig.
However, it's important to note that:
* Young piglets: It can be difficult to determine the sex of young piglets, as their genitalia may not be fully developed.
* Experienced handlers: Experienced pig handlers can often determine the sex of a pig by observing subtle differences in body shape and behavior, but these are not definitive methods.
If you are unsure about the sex of a pig, it's best to consult with a veterinarian or experienced pig farmer. They can provide a definitive answer through a visual examination or other methods if necessary.
