First forum post here, have been reading on the forums for quite a while.

Last fall I got a set of 5 piglets from a nearby farm, I thought I was getting 5 girls, but after 2 months realized one of them was a boy, and her was obviously intact since we did not realize he was a boy. The short story is that I got rid of the boy in March (clearly not soon enough) and just this week I realized that one of the girls is pregnant. As her brother is the only male they have ever been near I have to assume he got her pregnant.

What do you think I should expect from the pregnancy, in terms of what shape the piglets will be in when they come out? I am new to breeding and birthing animals. I know there is often a certain amount of inbreeding in some breeding setups, but am not sure what to expect in this situation.

Thanks

Expect either a small litter or a regular sized litter with high mortality.

Normally, the piglets will be fine, but I would raise them to butcher weight then put them in the freezer.

I wouldn't be inclined to use them for breeding stock.

You have what we called a 'bacon litter'. If you get anything that lives, raise it and put it on your table.

Unless the background of your pigs has a history of defects, I wouldn't expect to see a problem with the litter. Defects don't simply pop up out of nowhere. Unless you intimately know the background of your pigs bloodlines, I wouldn't suggest doing inbreeding on a regular basis, though.

Thanks all for your replies. I have no intention of doing any further breeding using any of these pigs, these were only supposed to be freezer stock anyway.

Line breeding is fine for a one or two time event. As Su Ba mentioned, if there are no defect in the parents, then all that has happened is a single line breeding.
What it will show you is if there are any recessive gene defects in the sow and boar since they are brother/sister.
The gilts and shoats will most likely be just fine and don't need to be destroyed. They will eat fine and as long as you don't breed any shoats to any of your girls, all will be fine.

I would document the babies and ear mark them so you know who is who for the rest of their lives.

do get a new, non related boar, which can service all the girls, both those you have now and the new litter gilts should you decide to keep those.
do remove all shoats (you can tell visually a boy from a girl at 2 weeks old or even younger). Shoats can be sold for feeder hogs or put into your freezer as long as you do this before 8 months have passed since that is when the shoats can breed.

Hi, I didn't think that mine will mate cuz they came home together. But, I think my boy got his sister pregnant. Cuz I dint see her in heat again and somewhat she had gained weight which is hard to tell cuz she a big eater and used to push her brother away to eat his food lol.
Now, my choice that I need to make is since I'm relocating.  I'm keeping the possible Mama, will get her fix for sure and dane with the baby of hers if she give birth, but who should I take the father will be fix or other girl piggy that this Mama stay close to. I'm taking 3 but just don't know what's the best. The father who is her brother or other girl who is her companion. What do you think? Thank you

I have line breed sheep before and it is a roll of the dice

They either will be really great piglets or the worst possible.

If they are great ones, use the pig as breeding stock but you cannot go more then two generations.

It’s called line breeding and acceptable with livestock, it’s just risky because you might end up with bad stock. Who wants to possibly lose a whole year
