ive recently had my boar done to put him with some girls so he wasn't on his own, he was done on Friday and today was the day I tried to introduce them. I took them somewhere where neither of them had been before so it was a new place for them. I placed them all down and he started to hump the girls, so I googled why he was doing it, and it said it could take up to 6 weeks before all the seamen actually leaves his body?! is this true?! I really don't want Guinea pig babies lol
Hi!
A boar's behaviour will not change when he is neutered. He will still hump the girls. Just his ability to make babies.
However, when his testicles are removed, there is usually still semen in the tubes left, which can stay alive and viable for over 5 weeks post-op - unless your vet has also removed those...
I should know because my Tegan is the daughter of a supposedly safe over 5 weeks post-op boar (not one of my mine), and it caused a lot of upset to the rescue lady I had just recently adopted her mum and auntie from at the time! it REALLY can happen as late as that, and I have since heard of more cases. Most good British rescues now follow the 6 weeks guideline when neutering rescue boars or adopting sows out to live with a neutered "husboar"; but I have yet to hear of any accidents despite several years of this practice.
I am very sorry that your vet has not told you that a full boar needs to wait post-op. In your case, I would make a formal complaint.
If you are unlucky, and any of the sows was near her season, it only takes seconds for a pregnancy. Hopefully, your girls have escaped, but unless you know for sure which way things are going, you will have to treat any potentially pregnant sow as such.
Unfortunately, this means that you'd best open an ongoing support thread in our pregnancy section, where you can ask any questions and air any worries along the way. We have got pregnancy guides specifically for owners hat are dealing with an unplanned pregnancy at the top of the section, which you may helpful. They cover the whole period with all the details that you can reasonably know and need to do; I have cut out all the confusing/contradictory information that is floating around online and that is usually not at all helpful. When you start a pregnancy thread, please mention the cause, when your girls were with a boar and the age of your sows.
You won't be able to see anything for the 6-7 weeks until any babies start growing large enough to make a difference and to be able to be seen reliably on scan/x-ray if you want a vet confirmation; by then they get calcium in the skeleton and look different to other inner organs, which on occasion have been mistaken for babies...
During that time, it is very important that you ask for and especially follow our diet advice as that is the area where you really can influence the success chances for pregnant sows and their pups. Our general guide will tell you what to expect. Please take your time to read the information.

You can keep your boy next to your sows for company and interaction through the bars for the time being. He won't be happy after meeting them, but that can't be helped. Since they only met shortly, there is a good chance that nothing has happened, and you do not want to spoil that! A sow that lets a boar mount her during introduction is not necessarily in season, but she is signalling acceptance of him.
