Hi again,
Looks like my previous post caused a tad of amusement :-)
Obviously if the pig is not bothered by it, then let it be, however, I have seen it where the ear does get so swollen the pig holds its head on its side and cant right its head.
When that happens you have to do something, whether it be a 10Kg weaner or a 230Kg Boar, obviously amending the procedure for restraint to suit.
Yes it can be a worrying experience with a large animal, I remember only too well me and a vet in a livestock trailer trying to clip the hoofs of a 200Kg Sow who did not want her nails clipped !
Thanks
