Fenceless Holistic/Rotational management

This entire idea is for the formation of a theory, I do not graze or have the land to graze. Am just thinking about it in my head:

Anybody know the viability or possibility of grazing herd animals(sheep, cattle, goats) in a rotational/holistic format without the use of physical fences. Would like to stay away from manufactured fences (barbed, electric, plastic/polyester). This leaves only a couple of options. Wood, stone, hedgerows, or dogs. Wood would be rather expensive and time consuming to make as well as unrealistic as it would have to meet specifications for multiple animal sizes. Stone seems workable on the utility side, however it would also be way to expensive and time consuming to make on any real scale. Hedgerows sound good until you realize it will take a couple years to make a livestock “proof” fence across large sections of land. This leaves the prospect of dogs which seem to work well in my head but am curious to know if the herding capabilities of dogs would be capable of forcing livestock to graze only portions of a field at a time (for the rotational/holistic aspect). Are dogs viable. Am I missing something?

“Hedgerows sound good until you realize it will take a couple years to make a livestock “proof” fence across large sections of land.”

Would also like to mention the fact that hedgerows aren’t the easiest things to alter so would only really be effective as fencing on the borders of the property or general land separation.

Yes it is possible. You will need something around your perimeter. There will be a bit of wandering. This will probably only work if you can have one large tract of land with multiple watering points.
You will then need either an extremely well trained herding dog, or horse, or both, salt would also help. You would plan out ahead of time where you want your herd\flock on each day. Then use your horse and or dog to move the stock where you want them. Once they are in the right place you reach the hard part, you need to settle them in that spot so they stay. You need to take the motion out of the herd, which means going to the front of the herd and turning some around, once they are all facing different directions and grazing they are settled. Having some salt in the middle of the area you want them in will attract them to that spot.
This idea is about replacing fences with extraordinary stockmanship, this is extremely difficult to find. With this system at no point should a cow, sheep or goat move faster than a walk. Herding dogs tend to create too much excitement for this to work. What is best for this is one person on an old horse.
If the stock do get excited and run the herds momentum will probably take them right past where you want them to stop.

You need a Shepard. Or cowboy.
