Electric fences are easily adapted to most applications and can be installed temporarily or permanently. These fences are relatively easy to maintan and economical to build. However, they require routine inspection and maintenance to ensure proper operation and protection capability.
How an electric fence works
For electricity to flow in a system, such as an electric fence, there must be a complete and uninterrupted (closed) circuit. The electrical current must travel from its source (fence energizer) through the circuit (fence) and back to the source. This flow only occurs when a charged wire of the fence becomes grounded.
Under normal operating conditions, an electric fence functions as an incomplete (open) circuit with repeating pulses of electricity generated by the energizer sent through the charged wires of the fence. When an animal touches a charged wire, it grounds the fence, creating a closed circuit. An electrical pulse travels through the animal and back to the energizer, delivering a shock to the animal.
The electric shock is unpleasant to animals (and humans, too), but is not lethal. However, if an animal gets caught in a fence for an extended period, it may dies of stress. An electric fence is humane, since it can only shock the animal if it persists in making contact; once the contact is broken, the fence does not 'spit' at the animal.
Other objects and materials including vegetation, sticks, fallen trees and non-insulated posts in contact with charged wires can also create a partial or total closed circuit. This partial or closed circuit can result in a reduced electrical charge (voltage) and an inadequate shock to repel predators that contact charged wires of the fence. Fences should be checked and maintained regularly to address this potential problem.
Electric Fence Designs
An effective electric fence for predator control consits of:
a source of the high-voltage signal, called an "energizer", that may be operated by a solar cell, a batter or, peferably, may be plugged into the domestic system -this generates short, highly peaked pulses of elctricity
a live wire, or wires, of high tensile steel that carry the pulses around the enclosed area
posts, that can be made of cedar, steel, or fiberglass, depending on budget and topography
a grounding system, starting at the energizer, one side of whose output is grounded through a system of low resistance ground rods, which should be carried along with the live wire around the enclosed area
insulation, to insulate the live wire from accidentl contact with the ground, whish would short it out, and render it ineffective
tension springs on long stretches, to limit the mechanical tension in the wires as they contract when air temperature drops
lightning protectors, since the live wires are exposed to lighning strokes and induction from power lines

Landfills
Electrifying your landfill should, not only be mandatory, but should be one of your first considerations. A well-designed and properly installed electric fence will prevent bears from accessing your landfill. There are some special considerations that should be considered when electrifying such a highly attractive site. You will need to consider bears digging underneath the fence. To prevent digging, you can lay down horizontal fencing one foot below the surface.
Bears also have a habit of entering the gate when it is left open and often get caught inside. There are a couple of options to prevent access through open gates: (1) automatic sliding gates that open and close when the weight of a vehicle passes over the entrance, and (2) electrified cattle grate entrance. Of these two options, the second will be more effective and easier from a human-use standpoint.
We started our first ranch in Costa Rica about 35 years ago, in 1980. We began by raising Brahman cattle like everyone else. Brahman are known for their ability to thrive in hot tropical climates. And they have a relatively huge, meaty rump compared to other cattle breeds. But Brahman are not known for tender meat.
So about 15 years ago, we began a quest to create cattle hybrids that maintained the tropical heat tolerance and large rump of the Brahman, but also incorporated the superior meat quality of the European cattle breeds.
We started by importing Red Angus genetics from the renowned 5L Ranch in Montana. The bull we used is called Norseman King, and he is one of the most-impressive examples of the breed.
The offspring from this genetic cross are very impressive animals. They are long, well structured, extremely fertile, as well as very gentle and curious. The cows from this cross are especially good mothers.
The introduction of Red Angus into our herd was an enormous leap forward in terms of meat quality. But then, a little more than 4 years ago, we had an opportunity to dramatically improve meat quality again, by acquiring semen from 4 different bloodlines of Japanese Wagyu.
You may not recognize the breed name, Wagyu, but you probably recognize the term “Kobe beef.” Kobe beef comes from Wagyu cattle raised in Japan’s Hyogo Prefecture. Kobe is more like a trademark — only meat from Wagyu cattle raised in Hyogo can be called Kobe.
We chose Wagyu cattle because this breed has some interesting and unique characteristics. They have the highest genetic propensity to produce marbled meat. Marbling is what makes beef tender, juicy, and flavorful.
Wagyu meat is also unique in that it has the highest “good fat to bad fat” ratio of all the cattle breeds. It is also extremely rich in Omega 3 and Omega 6 fatty acids. It is so unusually healthier than other beef that some people describe it as the “olive oil of animal fats.”
Today, we have more than 1,100 cattle on our ranches. Of those, only the very best will be selected for our artisan beef program. They are then given additional pampering and care, and we maintain extremely strict health protocols for them. If one of these animals is ever injured or ill, and requires a life-saving treatment of antibiotics, it is then removed from our artisan beef program.
Just to be absolutely clear … all of the beef we sell under the Hacienda Sur name is guaranteed to have never had any contact whatsoever with antibiotics. Never.
We guarantee the same for hormones. Some cattle producers give their animals growth hormones so they grow faster and bigger. Others give their cows estrogen so they all come into heat at the same time. We completely disagree with both practices. We have never used hormones on our cattle, and we never will.

Speedrite Electric Fence Energizers offered by Valley Farm Supply was established in 2004 by Lancaster County local, John “JC” Remsberg, to provide quality farming supplies and equipment. The supply store warehouse is located in New Providence, PA. However, they provide service to professional farmers and hobby farmers throughout the country and internationally. Valley Farm Supply was initially started as a concept through eBay®, but as demand grew, so did the business. Over the years, one thing has been constant – the friendly, knowledgeable service you receive.

JC’s knowledge regarding farming supplies is unparalleled. Working in the farm industry, before becoming a wholesale dealer, gives JC the advantage that big box farming stores just don’t have.
JC talked with me about countless stories, where customers have looked to Tractor Supply Company® and other larger stores for help, only to end up dissatisfied. In one case, a customer called looking for fencing to keep bears from getting into his farm. The grade of fencing from Tractor Supply Company® did not hold up to the test. This customer was just starting out his Beekeeping ventures and had 10,000 honey bees. JC was able to get him durable fencing that would work keeping the bears at bay, and sent him videos guiding him on how to install it correctly.
Valley Farm Supply is also one of the largest wholesale dealers for Gallagher® equipment. In addition, they carry many other brands of truest, speedrite, staff, patriot, and cyclops electric fencing, livestock watering systems and grazing supplies. Being one of the largest dealers in the Northeastern USA, they are able to pass amazing savings on to their customers.
