Hernia was my first thought too.
If it's not causing him pain/discomfort and you're planning on slaughter at around 6 months just keep an eye on it. Providing it's not strangulated or causes a twist in the gut it really shouldn't affect things. But I would talk to the breeder who you got him from, they may not be aware, and from my point of view as a breeder I'd want to know if one of my pigs developed something like that. Of course, it may be that they are aware of it, but I would have thought they'd have at least mentioned it

I have a young Kune Kune boar at present who has a scrotial hernia (KK's are really prone to them) as he's grown so has the hernia. But (without sounding hard hearted) he's destined for pork so I see no need to do anything about it. Obviously if he ever seems pained or troubled by it we'll get him to the vet asap.
