That is quite important. All equine lovers may have been quite concerned about this before. But they must also be mindful of making the excuse that their land is also just too large for them to police. It is their property, so they should be taking every measure to secure their agricultural property and all its contents at all times. No excuses, please. Equine lovers have concerns about the fences. That may have been quite understandable before.
This in the sense that fencing structures have been deliberately set up to provide some form of barrier against unwanted intruders. The intruders could be wild predators and blatant cattle and horse thieves. To prevent them from mounting the fence, crawling their way under and over, the fences have been barbed wired. Now, this would have been quite dangerous for the horses. They love to roam, and so they should.
In their daily cavorting they may come close to the edge of your property. As a keeper of mainly equine stock, you can have a specialist horse fence installation done. Your specialist service provider will also be assisting you with all other activities on the ranch. He will be looking after your corralling requirements for those times of the day when it is necessary to ring the horses in. You can also use such fencing for other farming activities, particularly if it is the case that you are keeping other livestock, particularly stock that needs to roam, just like the horses do.
Now, if crime and wildlife activity is pretty rampant in your rural setting, you might wish to consider some form of double glazing if you will. You will need an overreaching fence beyond your horse fence to take care of security.
