Benefits

The LAC-TEK Ovis-40 Automatic Milk Nursing Machine automatically mixes small quantities of powdered milk replacer/formula with warm water at a desired concentration. The mix is made in regulated batches. When the milk level goes below the sensor, the feeder starts a new batch. Animals take the mixed liquid by means of a rubber nipple.

  • Provides milk for up to 40–60 orphans
  • Animals are of equal quality to those raised on a mother at weaning
  • Built-in thermostat warms water to a preset temperature
  • Mix only what you need—less spoilage
  • Adjustable milk/water ratio; change concentration as animals age


Specs

  • Dimensions: 17" x 19" x 28"
  • 4 lamb/kid nipples
  • 4 nipple connectors
  • 12 feet of nipple tubing
  • 2 nipple panels—up to 3 nipple panels when using optional T-connectors
  • 2 gallon reservoir (for warming water)
  • 25 lb capacity stainless steel hopper for milk powder
  • Rating: 110 volts, 1500 watts; requires a 15 amp circuit breaker
  • Operating manual


How to Use

Refer to included Operating Manual. (See download links above.)


Precautions

  • If mixed milk has cooled lambs won’t be eager to consume cold milk. Not a problem unless only 1–2 lambs/kids.
  • Spoilage can occur in warm weather.
  • Warm temperatures may cause milk to froth which covers the sensor. This delays the mixing of a fresh batch.
  • Machine must be kept from freezing. Some build an insulated box and/or install a heat lamp.

Won’t use the Ovis until winter, but the ordering process was very easy and all my pre-order concerns were addressed. Several friends have this machine and are pleased with it and the service.

Bought this machine as due to weather and multiple births I’ve had a lot of orphan kid goats. Got it set it up and had small issue with machine. The people at Biotic were fantastic in helping fix the issue of machine not mixing consistently and supplying parts. If you have limited time and want to see your orphans to thrive get one of these, it is well worth the money. I don’t often leave reviews but the Ovis-40 milk machine and Mark from Biotic definitely deserve 5 stars.

We purchased our OVIS milk feeder in October. What a blessing it is for our smaller sheep operation (43 Polypay ewes) but this machine could easily handle more than what we are currently using it for. Machine works perfect, our lambs are growing like weeds. The machine pays for itself! Our daily growth rates are exceeding more than we could have ever imagined. Never going back to bottles.

We do not plan to use the Ovis feeder until May.

Everything arrived in great shape. I have been reading through the setup, cleaning and maintenance, and I look forward to seeing it in action.

Appreciate the videos and photos that Premier provides online.

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.

Premier 1 Supplies

Dan Morrical joined the Iowa State University staff in 1984 as Extension Sheep Specialist after completing his doctorate degree at New Mexico State University. He held the rank of Full Professor as of July 1, 1995 and retired from full-time teaching in 2017.

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.
