I just got a couple of dozen very wild unhandled sheep from a fellow going out of the business. A lot of them showing bottlejaw. Ran them through a makeshift corral into a chute made of old pallets. Without this drencher I think this might have never been possible. It is handy to be able to change the dose on the fly. Although you do waste a small amount when dialing down, the convenience is worth it.

I have been using the same brand drench gun over the past 7 or so years and wormed hundreds of sheep. It really is worth the cost as it saves time and makes it a lot easier to treat a large flock. The only problem is that I neglected to order the drench nozzle. I think that the product summary needs to clearly say that you need to order the drench nozzle separately if you plan to use the product to worm animals. Since I don't want to pay shipping, I need to wait until I have other items to order and add the nozzle to the order (bummer).

Purchasing my fourth drench gun. We run 120 doe goat herd, and it is a breeze worming them all the same afternoon with two people and a good working chute system. Because they are cheap compared to the competition, I always keep an extra on hand for parts or in case one breaks. They are easy to clean and maintain. Only issue I have ever had is an old doe grabbing onto the drench gun nozzle when I was pulling it out and it cracked the plastic tip where it connects. This completely breaks the gun because the check valves will not work properly when air can seep in the crack. This was after about 4 years of use and a lot of doses given. Well worth the money, and comparatively a well made affordable drench gun. I just took my last spare and used it to apply delouse topical treatment, which we had been using a old single dose hand drencher for. It really sped up productivity running two of them. I would hands down buy it again.

Bill F from New Hampshire

The unit feels semi-disposable. It performed well the first time I used it, but there were a couple of glitches. The most important was that about halfway through drenching my lambs with Valbazen I noticed that the dosage had increased to 6 ML, enough for a 200-pound animal. Fortunately, Valbazen has a very high degree of safety, but who knows how many lambs received this overdose before I noticed it? The second was that the drench nozzle has a tendency to shift, requiring me to stop and adjust it quite a few times -- maybe every 10 lambs or so.

I miss the old Syrvet drenchers, which were more rugged and durable than this, but my recent experience with two of them (purchased elsewhere) is that while they felt rugged they were in fact junk, which could fall apart after drenching as few as 100 lambs. I believe this unit will outperform the Syrvet, despite its shortcomings.

About Conductivity

Conductivity measures the amount of electrical current a material can carry. The opposite measure is known as resistance.

Tinned Copper Superconductor

Many of Premier’s electric net fences feature a green and white superconductor that has both stainless steel and tinned copper filaments for optimal conductivity.

These “premium” nets are 10 times more conductive (38 ohms per 1000') than “basic” nets offered by our competitors. This enables the electric pulse to travel much farther and be less affected by weed contact.

Customers who are unhappy with netting are often those who’ve chosen nets from China or their farmstore equivalents.

Types of Line Posts

Line posts are built into the net. Three options are available.*

Line Posts Compared
  1. Single Spike (SS)
    The best choice, unless your soils are always soft or very hard.
  2. Double Spike (DS)
    Posts allow you to push in the spikes with your foot. When soil is hard or rocky, double spikes are more difficult to install and remove.
  3. Drivable Posts (DP)
    Allows use of a mallet or dead blow hammer for installing posts in dry, hard or rocky soil. Features a “spike stop” for extra support and internal fiberglass ribs for added strength.

Tip: To insert a line post into frozen or hard soil, use a power tool to drill pilot holes.

* Not all fences have all line post options.

About Positive/Negative (Pos/Neg) Nets

Is your area dry?

Conventional electrified fence systems rely on soil moisture to be effective. However, not all areas have the required moisture.

Dry soil increases resistance—a weaker, less effective pulse occurs that does not deter animals.

To overcome this, Pos/Neg nets* are wired to allow the use of every other horizontal strand as an extension of the ground terminal. Because half the strands are connected to the ground terminal or ground rod, reliance on soil moisture is reduced. A PowerLink must be purchased separately to make the secondary ground connection.

How it works…

In order to receive a shock, the animal must touch both a positive (hot) and negative (grounded) strand at the same time. This will deliver more pain to the animal than an all hot net (Pos/Pos) because moisture in the soil is not required to complete the circuit.

Pos/Neg fences can be converted to Pos/Pos in moist conditions. Remember, all fences must be kept free of vegetation.

* Not all fences have Pos/Neg options.

Line Post Spacing

“Plus” nets—6'8" spacings between built-in line posts*

Line Post Spacing

Standard nets—10' or 12' spacings between built-in line posts*

* Spacings are approximate.
Distance between built-in line posts may vary by product.

Essential Energizer Advice

  • Buy a larger energizer than necessary. When the fence pleases, most folks will buy more fence—and need additional output.
  • Use a low-impedance intermittent pulse energizer.
  • Use a fence tester to check the voltage often.
  • Use enough ground rod(s)—included with our energizer kits.
  • Don’t allow your lead acid battery to discharge below 40%.
  • Use insulated wire that is designed for electric fences.
  • Always connect the fence to an energizer, not an outlet.
  • Visit this link for answers to other common energizer questions.

Two Basic Types

  1. All-in-one Solar
    • Solar units are very portable.
    • Because they need a battery, these units are more costly to purchase and operate than plug-in units.
    • Batteries are less effective in cold temperatures (deplete faster).
    • Most farmstore solar units are too weak, in joules of output, to properly energize netting. That’s why we designed our own.
  2. Plug-in & Battery
    • Least cost to purchase and operate per joule of output.
    • Best for fences exposed to heavy vegetation.
    • Cold temperatures do not affect performance.
    • Recommended for whole-farm systems, but can be complex to install. Higher output requires more ground rods, underground cables, multiple output terminals, etc.

While at Iowa State University, Dr. Dan Morrical was responsible for educational programs in all areas of sheep production, ranging from nutrition, genetics, marketing and management. Research areas focused on applied projects in the areas of nutrition, forage utilization, genetics, out-of-season breeding and lamb survival.

Dr. Morrical has been heavily involved in providing educational resources to the sheep industry. He has authored over 30 extension fact sheets, ration balancing software programs, grazing videos and co-authored the nutrition chapter of the SID Handbook with Dr. Margaret Benson from Washington State University.

Dr. Morrical now serves as Premier’s on-staff small ruminant nutritionist and sheep production advisor. Most recently, he’s introduced a line of “GOLD FORMULA” mineral premixes under The Shepherd’s Choice® brand, aimed to maximize hoof health and immunity.

Braided vs. Twisted

Braiding instead of twisting the horizontals increases the frequency of metal filaments on the outside of the strand.

Braided vs. Twisted Electric Net Fences

What’s the benefit?

  1. More metal is exposed on the outside of the strand. This enables improved animal to conductor contact. The electric pulse is better able to travel from the fence and into the animal, resulting in a memorable shock.
  2. A tighter, braided weave results in fewer snags when carried or pulled through pastures, reducing frustration.
