A DIY cattle oiler can be a practical project for ranchers who want to build a simple self-application system for their cattle. The basic idea is straightforward: cattle rub against a mop, rope, brush, or other applicator that distributes an approved pest-control product onto their coat.

There are several ways to build a homemade cattle oiler, from a simple hanging mop or cattle rub to a more permanent setup with a reservoir and gravity-fed applicator. The right design depends on your cattle, where the oiler will be installed, the materials you have available, and how much maintenance you want the system to require.

Before building one, it helps to understand how commercial cattle oilers are designed. Looking at the way tanks, mops, brushes, valves, and mounting systems work together can provide useful ideas for a homemade system.

How Does a DIY Cattle Oiler Work?

A cattle oiler takes advantage of a behavior cattle already have: rubbing against objects. Instead of manually applying a treatment to each animal, an oiler places an applicator where cattle can contact it as they rub against it or walk underneath it.

A basic homemade cattle oiler generally needs three things:

• A strong mounting point or frame
• An absorbent or brushing surface that contacts the animal
• A way to apply and replenish an appropriate livestock pest-control product

More elaborate designs may add a tank or reservoir that feeds the applicator. Simpler cattle rubs may rely on an absorbent rope or fabric applicator that is treated periodically.

Choose the Type of Homemade Cattle Oiler Before You Build

There is no single DIY cattle oiler design that is right for every operation. Decide how you want the cattle to interact with the oiler before buying materials or building a frame.

Hanging Mop or Cattle Rub

A hanging mop cattle oiler design can be installed across a controlled passage where cattle naturally walk underneath it. The animal's back and sides make contact with the hanging material as it passes through.

This approach is relatively simple, but the mounting points must be strong enough to withstand repeated pulling and rubbing by cattle.

Brush-Style Cattle Oiler

A brush-style design gives cattle a firm surface to rub against. Commercial brush cattle oilers commonly combine heavy brushes with a reservoir and controlled liquid delivery system.

A homemade brush setup requires particular attention to mounting strength. Cattle can put considerable pressure against a brush when scratching, so lightweight brackets or loosely mounted posts are poor choices.

Gravity-Fed Oiler

A gravity-fed system uses a reservoir positioned above or within the applicator. Liquid moves from the reservoir to a mop, felt, brush, or similar material.

This type of system can require less frequent treatment of the applicator, but it is also more complicated to build. The flow needs to be controlled so the applicator remains properly treated without continuously leaking or draining the reservoir.

Materials for a DIY Cattle Oiler

The exact materials will depend on the design, but durability should be the first consideration. Cattle oilers are exposed to weather, dirt, livestock, and repeated physical pressure.

Common components may include:

• Heavy posts, steel tubing, or another strong supporting structure
• Chains, brackets, bolts, and other heavy-duty mounting hardware
• Rayon mop material, heavy rope, brushes, felt, or another suitable applicator
• A compatible tank or reservoir for a gravity-fed design
• Hose, fittings, or valves when the design requires controlled liquid flow
• Weather-resistant fasteners

Avoid exposed sharp edges, protruding bolts, loose wire, pinch points, or other components that could injure an animal. Materials should also be compatible with whatever treatment will be used in the oiler.

How to Build a Simple DIY Cattle Oiler

Because homemade cattle oilers vary considerably, there isn't one set of dimensions that works for every design. A practical building process is more useful than trying to copy a single set of measurements.

1. Choose the location first. Identify a place cattle already use regularly, such as a controlled travel lane or an area associated with feeding or mineral access.
2. Determine how the cattle will contact the applicator. Decide whether they will walk beneath a hanging mop or rub against a brush, rope, or other surface.
3. Build or select the supporting structure. The mounting system needs to tolerate repeated contact from full-size cattle without tipping, loosening, or developing sharp edges.
4. Attach the applicator. Install the mop, rope, brush, or other material so cattle can make useful contact without becoming caught in the equipment.
5. Add the treatment-delivery system. This might be periodic treatment of an absorbent cattle rub or a reservoir feeding an applicator. If using a tank, make sure the flow can be controlled.
6. Inspect the complete system before use. Look for sharp edges, loose fasteners, exposed wire, entanglement hazards, leaks, and weak mounting points.
7. Observe the cattle using it. Watch the oiler during its first period of use. Make adjustments if animals cannot make good contact or are putting unexpected pressure on part of the structure.

Where Should You Put a Homemade Cattle Oiler?

Placement can be just as important as construction. An oiler that cattle rarely encounter will require animals to seek it out on their own.

Look for a location where cattle naturally travel. Depending on the operation, that could include a lane leading to water, a mineral-feeding area, or another controlled passage.

For a hanging cattle oiler, the location should encourage the animal to pass beneath the applicator rather than simply walk around it. A brush-style oiler can be placed where cattle have room to approach, rub against it, and move away without creating congestion.

Do not create a location where animals can become trapped or where dominant cattle can prevent others from moving through the area.

Using Pest-Control Products in a DIY Cattle Oiler

The oiler itself is only the application equipment. The pest-control product is a separate consideration.

Use only products labeled for the animal, pest, and application method involved. Follow the product label for mixing, application rate, protective equipment, treatment intervals, restrictions, and other directions.

Do not assume that a product is appropriate for an oiler simply because it is approved for use on cattle. Application methods and label directions can differ.

If you are unsure whether a particular product is appropriate for your cattle or your oiler design, check the product label and consult the product manufacturer, your veterinarian, or an appropriate agricultural professional.

Maintaining a Homemade Cattle Oiler

A DIY oiler should be inspected regularly. Cattle can loosen hardware, wear through applicators, bend brackets, and put considerably more force on a structure than might be obvious when it is first built.

Check:

• Posts, frames, and mounting points for movement or damage
• Chains, bolts, brackets, and fasteners for wear or loosening
• Mops, ropes, brushes, and felt for excessive wear
• Tanks and hoses for leaks
• Valves or feed systems for proper operation
• The surrounding area for spilled treatment or damaged equipment

Worn applicators should be repaired or replaced rather than allowing cattle to continue using damaged equipment. Barn World carries cattle oiler parts, including replacement components that may also be useful when maintaining an existing livestock oiler.

DIY Cattle Oiler vs. a Commercial Cattle Oiler

Building your own oiler can make sense when you already have suitable materials, enjoy fabricating farm equipment, or need a setup adapted to a particular location.

A commercial cattle oiler may be a better fit when you want a complete system with a purpose-built tank, applicator, mounting hardware, replacement parts, and a known method of controlling liquid flow.

For example, Barn World's brush-style oilers use a tank and controlled dispensing system, while mop oilers use a simpler hanging, gravity-fed design. Looking at both styles can help determine whether building your own is worthwhile for your operation.

If you'd rather start with a complete unit, compare Barn World's cattle oilers, including brush, mop, and apron-style designs for different livestock setups.

A Practical Approach to Building a Homemade Cattle Oiler

The best DIY cattle oiler isn't necessarily the most complicated one. A simple design that cattle use regularly, stays securely mounted, is easy to inspect, and works properly with the chosen treatment can be more practical than an elaborate system that requires constant adjustment.

Start by deciding where the oiler will be used and how the cattle will contact it. From there, choose a durable applicator and mounting system, build with livestock safety in mind, and make routine inspection part of its use.

If a homemade system becomes difficult to maintain, replacement cattle oiler parts or a complete livestock oiler can provide another option without abandoning the basic self-application approach.
