How to Use

Use the Caisley Applicator to install:

  1. The male and female tags will come to you slightly connected. You will need to tear them apart.
  2. Press the black clamp and slide the female part of the tag under the metal spring finger. The printed side of the female tag will be against the jaw of the applicator.
  3. Slide the male tag over the metal pin. Be sure to push it all the way onto the pin! The printed side of the male tag will be against the other jaw of the applicator.
  4. Ensure the male pin aligns with the female opening and both tags are fully seated. (Don't squeeze the applicator yet.)
  5. Place the ear between the jaws of the applicator. While gripping the ear, quickly and firmly squeeze the handles together until the male tag is inserted through the ear and into the female tag.

Proper ear tag placement for cattle

Tag placement is critical to success!

Whenever possible, tag when the ear is dry and clean. Avoid the large veins in the ear. Tissue around damaged veins heals slowly—so it’s prone to infection.

Designs that allow air near the wound will heal more quickly. For best results, apply an antibiotic, a fly repellent and/or a disinfectant to the ear tissue or tag.


Customization

We can custom laser imprint (at no additional charge!) EID cattle tags before they leave our door. Each tag will be assigned a unique animal EID number that is registered with the USDA. Premier has no control over this number.

Imprinting options include:

  • Farm name (or other text)
  • Numerical sequence (e.g. 100, 101, 102, etc.)
  • Last 5 digits of Animal ID (AIN)
  • Blank

Custom imprinted ear tags are NOT returnable.

Premier will provide a data export (CSV format) of assigned Animal IDs (AIN) once your order has been shipped.


Common Questions

Why does the identification number start with 840?
EID tags that begin with the numerals 840 are considered an official animal identification tag by the USDA. Having an Official ID allows for interstate travel, along with disease traceability, data capturing and sharing. With USDA tags, a Premises ID (PIN) is required.

You can apply for a Premises ID for through your state’s animal health department.

What is the difference between HDX and FDX tags?
HDX and FDX tags both adhere to ISO standards and are compatible with the same EID readers. HDX tags excel at transmitting signals through interference, such as metal objects and fluorescent lights. FDX tags are suitable when read range is less critical. Typical read ranges are 15–18" for HDX tags and 13–16" for FDX tags.
Does the EID tag save information or track movement?
No. An EID ear tag utilizes a very low frequency which is only readable from a short distance. It does not use GPS tracking technology.

When an EID tag is scanned, a unique 15 digit number is returned. You can use this number in your own software or equipment to track the health and genetic records for the animal.

NEW!Ear tags with a built-in tissue collection unit are now available. Combines an electronic ear tag with the functionality of taking a genetic sample—in one step!

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.
