Quote from "keeping pigs by Tony York" Hernias: if a piglet has a hernia it can be operated on but is rarely necessary and is not something i would recommend. if the pig is intended for fattening, is not in any discomfort, is eating well and showing no other signs of illness it is best left. The meat will not be affected and although a little unsightly it will not affect the pig.you may find it comes and goes, whilst in some cases it will disappear altogether before the piglet is even weaned. The trauma of an operation can cause the pig more stress than the hernis itself. A hernia is simply a rupture that may be caused by strain or being trodden on by another pig. In some cases, a hernia may be a congenital abnormality. if there are a number of piglets from the same litter born with hernia's or that develop hernias as young weaners then you should seriously consider changing or culling the boar.
