FEMALE
The sows usually have a smooth swelling over their genital area. Sometimes, it can be bumpy looking, making you think it might be a male! If you gently part the genital opening, on a sow, a "Y" shaped opening should appear.

It should usually be pretty easy to sex an adult male -- especially in this case. Note on this photo how you can see the ridge of the shaft underneath the skin between the testicles. This is the same \'ridge\' that you feel for in babies and young boars as well.

Of course, you can still get a penis to extrude on a neutered male.

Great pictures.  I have rabbits and guinea pigs and it seems like it is a lot easier to sex the guinea pigs than the rabbits.  I have a pregnant female pig, who when she has her babies, I can sex them easily with the pictures.

Thanks so much for the info!  I am "babysitting" a GP this weekend, and had no clue about their behavior or nutrition!
