Regular Ranch Fence.. DOES NOT KEEP DEER IN.. by any means.
4 or 5 strands of barbed wire only serves as a purpose to keep Cattlein and provide a property boundry line.
Deer Hop, or go under these fences with no problems at all.
actually.. even full grown cattle have NO PROBLEM jumping over a regular Barbed wire fence.
i see it alot. they just normally Dont, because they have no reason to and there not Afraid of Humans.
But i have watches Large Cows just Hop right over barbed wire fences.
as a matter of fact, im having that problem with the neighbors cattle every day this week since i put up my deer feeder.
they hop over, to get to the corn. and Knock my feeder over.

one will spend several hours looking for a broken fence, when cows are out.
when many times.. its not broken anywhere
