The two types of fencing that I will never use are barbed wire and high tensile. I know many people use high tensile and think it is safe for horses, but it is not. The stuff will cut a horse to ribbons if they run into it. I have seen it happen and I know personally of several horses who were either gravely injured or killed by high tensile.
The fencing you see in many of my photos is designed for rotational grazing. It is a light weight poly twine with tiny stainless-steel filaments running through it. The posts are fiberglass. It is the only fencing that I have used for a number of years. I would like to build a more substantial perimeter fence around my property using wide poly tape and wooden posts at some point, but due to expense, that is far off. While the fence does not look very substantial, to the animals it is. Electric fence is more of a psychological barrier then a physical one and I have found this fencing to be highly effective and very safe.
The main thing to remember about all fencing, no matter what it is, is that animals will challenge it if they are crowded, discontented, panicked or overly hungry. This fencing works well for me because my animals are none of those things, they have enough space that even in a panic they don't go through the fence. This is not good fencing to use if animals are crowded or in populated areas where keeping people out is just as important as keeping the critters in.
Farm Buddy also uses this same fencing for her cattle and has done so for at least twenty years. This field is separated into two large rectangles (you can just see the divider fence on the right side of the picture going up the hill). You can't quite see it, but there is another fence about 100 feet behind the cows. Every day Farm Buddy moves that fence a little ways up the hill giving the cows fresh grass. When they reach the top, they start down the other side. By the time they get back to the starting point, the grass is ready to graze again.
