Electric Fencing for pigs
Pigs are easily kept in by electric fences , they are thin skinned have little hair and wet noses plus they are intelligent and learn.
When first introduced to a electric fence they will need to be educated . Pigs and piglets will at first seem to run through the live electric fence, in fact they panic at the shock from the fence and more often than not end up on the out side of the fence. It can help if a training pen is erected that has a second fence ( stock fence , wall ) behind the new electric fence so they can not go too far. After a few shocks the pigs learn to respect and avoid the electric fence. This adversion to the fence can continue even after it has been moved to the point that they will not cross the old fence line , putting down straw over the old fence line can help .
Please do not take these heights as cast in stone you will need to adjust the heights depending on breed size, age and the mix of age range.
Adult full size pigs only
Two lines at 25 cm and 45 cm
Piglets and adults
Three lines at 15 cm, 25 cm, 40 cm
Because the first line can be as low as 15 cm ( or lower if required ) it is critical the is NO vegetation touching this bottom line. Any plant touching the fence will allow power to leak to earth making the fence substantially weaker. Additionally watch for soil building up from the pigs rooting and ultimately touching the bottom line of the fence.
If you are moving the pigs abut and using temporary posts watch for the posts being under minded by the pigs rooting . Metal pig tail posts grip the ground better than plastic posts because of the large metal triangle in the ground.
