You will not only have to keep the bulls out, but some cows will try to get in with the bulls during estrus.
Have found cows in the bull pasture a many a morning.
The top strand and the middle strand should do it. Wire. Barbed wire.
If you have metal posts, let the bottom strand be the gound. That way, the ground travels the length of the fence and will work throughout in dry weather.
I don't know about your area but in Indiana you can face jail time for a hot barbed wire!
If an animal gets caught up it it they can be terribly injured. I have about 5 miles of hot Hi-tensil and the largest charger I could find ( 12.5 jules ) so the barbs are not needed but the DNR has pictures of deer caught in hot barbs and if a DNR officer finds hot barbs you will get a fine ( up to $5,000.00 ) the first time and 6 months the second time! They also have the power to take your livestock.
