It is just a different way of doing it.
I use three 50′ lengths to make a paddock. The 1J energizer kicks out about 3to5kv. The cows touch it once or twice and they wont do it again. For that matter, the energizer is more bout keeping coy out then keeping the cows in.
Same with the goats.
Hogs on the other hand, they will try and test the fence. For them, I use a 2J energizer, putting out 5to10kv.
For both the cows and the hogs, the extra fencing to to create the next paddock, then open the makeshift gate between the two paddocks and let them in. Close the gate, tie off the paddock, hook up the energizer and done.
One length of fence weights about 15-20lbs. I can do a cow paddock in about 30-40 minutes to include water, and the energizer. If my wife is there to help, we can knock it out in 20minutes.
If it gets hot in the summer, I sometimes have to water the cows twice a day.
The hogs, they need a lot of water as those guys like to spill their water and make a wallow to stay cool. So I just do it for them.
Once they get trained, they know the drill.
The only livestock to see a vet was the goats. Twice in 7 years.
Oh, yeah! Pasture fed meat of anykind tastes a world different! My pork, has an extra porky flavor!
