6 Best Rotating Mineral Feeders for Pigs

You’ve just put out a fresh bag of expensive pig minerals, and a day later, it’s a clumpy, muddy mess soaked by an unexpected rain shower. This isn’t just frustrating; it’s money down the drain and a missed opportunity for your animals’ health. Providing free-choice minerals is non-negotiable for raising healthy pigs, but protecting that investment from weather and the pigs themselves is the real challenge. The solution lies in a simple but effective piece of equipment: a rotating mineral feeder.

Why Rotating Lids Are Key for Pig Mineral Care

A rotating hood or lid is the single most important feature for preventing mineral waste. Pigs are smart, and they quickly learn to nudge the cover with their snout to access the minerals below. When they walk away, the cover swings back into place, protecting the contents from rain, snow, and sun.

This simple mechanism solves the two biggest problems with open tubs. First, it keeps the minerals dry and palatable, preventing them from turning into a hard, useless brick after a single downpour. Second, it keeps the minerals clean. Pigs will inevitably try to stand in, root through, or defecate in any open container, contaminating the entire supply.

Ultimately, a covered feeder pays for itself quickly. You stop throwing away ruined minerals, and your pigs get consistent access to the nutrition they need for strong bones, healthy litters, and robust growth. It’s a small investment that protects a larger, ongoing one.

Behlen Country Poly Feeder: Durable & Weatherproof

The Behlen Country Poly Feeder is a workhorse for many small farms. Made from a single piece of molded polyethylene, it’s virtually indestructible and completely rust-proof. You can leave it out in the pasture year-round without worrying about corrosion or cracking in the cold.

Its design is straightforward: a rotating hood covers a single, generous compartment. The hood is light enough for even young pigs to operate but heavy enough to stay put in the wind. Because it’s plastic, it’s also relatively lightweight, making it easy to move between paddocks as you rotate your pigs through fresh pasture.

The main tradeoff is its single-compartment design. If you want to offer multiple mineral choices simultaneously, you’ll need more than one feeder. But for providing a single, complete mineral mix, its durability and simplicity are hard to beat.

Sioux Steel Ground Feeder for Easy Pig Access

The Sioux Steel Ground Feeder is designed with the animal’s natural behavior in mind. Its low-profile, ground-level construction makes it incredibly easy for pigs of all sizes—from weaners to full-grown sows—to access. They don’t have to reach up or strain, which encourages more frequent use.

This feeder’s heavy, wide base makes it exceptionally stable. Pigs love to rub and push against equipment, and the Sioux Steel model is built to stay put, preventing costly spills. The rotating hood is made of durable rubber, which is quiet and forgiving when a pig bumps it.

The primary consideration is its height. In areas with deep snow or extremely muddy conditions, a ground-level feeder can get buried or swamped. However, for most three-season pasture setups or in well-drained lots, its accessibility and stability make it an excellent choice.

Brower 3-Compartment Feeder for Mineral Variety

If you want to fine-tune your mineral program, the Brower 3-Compartment Feeder is the way to go. This design allows you to offer different minerals separately—for example, a complete mineral mix in one section, loose salt in another, and kelp meal in the third. This lets pigs self-select what their bodies are telling them they need.

Observing which compartments empty fastest can give you valuable clues about potential deficiencies in your herd’s diet or forage. Are they hitting the salt hard? Maybe your feed is low in sodium. This feeder turns mineral supplementation from a passive task into an active management tool.

Of course, managing three separate compartments requires a bit more attention than a single-bin feeder. You have to monitor and refill each one individually. But for the farmer who wants to provide a more nuanced nutritional program, the extra insight is well worth the effort. This is the best option for dialing in your herd’s specific needs.

Tarter Mineral Feeder: Stable, Tip-Resistant Base

Tarter’s focus with their mineral feeder is squarely on stability. Its low-slung, rounded poly base is incredibly difficult for a pig to tip over. A determined boar can flip almost anything, but this design makes it a real challenge, saving you from the frustrating task of scooping spilled minerals out of the mud.

The feeder features a large capacity and a durable, rotating hood that effectively sheds water. The anchor points at the base are a thoughtful addition, allowing you to stake it to the ground for an extra layer of security. This is especially useful if you have a particularly rowdy group of hogs or are placing it on uneven terrain.

While similar in material to other poly feeders, the Tarter model’s emphasis on a tip-proof design sets it apart. If you’ve ever lost a full feeder to a playful pig, you’ll appreciate the engineering that went into keeping this one upright.

Priefert Bull-Proof Feeder for Destructive Hogs

Don’t let the name fool you. While Priefert designed this feeder to withstand the abuse of a 2,000-pound bull, that same toughness makes it an outstanding choice for large, destructive hogs. If you raise powerful heritage breeds like Large Blacks or Tamworths, you know they can demolish equipment that isn’t built to last.

This feeder is made from heavy-gauge steel with a rubber lid, combining weight with durability. It’s an investment, but it’s likely the last mineral feeder you’ll ever buy. Its sheer weight keeps it planted, and the robust construction resists the relentless pressure and chewing that pigs can inflict.

The only real downside is the price and weight. It’s more expensive than poly models and much harder to move. But if you’re tired of replacing broken feeders every few years, the Priefert offers a buy-it-for-life solution for the most demanding farm environments.

J&J Lick Tank: A Low-Profile, Waste-Free Design

The J&J Lick Tank offers a completely different approach to mineral delivery. Instead of an open trough, it uses rotating lick wheels that protrude from the covered tank. The pigs lick the wheels, which pick up a small amount of the mineral mix from inside.

This design is the absolute champion of waste prevention. It’s impossible for pigs to spill, overconsume, or contaminate the mineral supply. Rain can’t get in, and the pigs can only take what sticks to the wheel, forcing slower, more deliberate consumption. It’s especially effective for fine, powdery minerals that might otherwise be blown away or wasted.

The main consideration is the type of mineral you use. This system works best with loose, granular, or powdered supplements. It’s not suitable for block minerals, and very coarse mixes might not adhere to the wheels properly. For those who prioritize zero waste above all else, the lick tank is an innovative and highly effective option.

Choosing Your Feeder: Capacity, Material, & Stability

Selecting the right feeder comes down to balancing your specific needs. There’s no single "best" option, only the best fit for your farm, your animals, and your management style. Think through these key factors before you buy.

A good feeder is an investment in your herd’s health and your farm’s bottom line. The initial cost is quickly offset by the savings in wasted minerals and the benefits of a properly supplemented diet for your pigs.

Consider these points to make your decision:

• Capacity: How many pigs are in the group? A larger herd needs a higher-capacity feeder to avoid constant refilling. For just a pair of finishing hogs, a smaller model is fine.
• Material: Polyethylene is rust-proof, lightweight, and durable. Steel is heavier, more resistant to chewing from determined pigs, but can eventually rust if the coating is compromised.
• Stability: Do you have large, active pigs that push things around? If so, prioritize a low center of gravity, a wide base, or the ability to stake the feeder down.
• Compartments: A single compartment is simple and effective for an all-in-one mix. Multiple compartments are ideal for offering choice and gaining insight into your pigs’ nutritional cravings.

Ultimately, choosing a rotating mineral feeder is about more than just convenience; it’s a strategic move toward more efficient and effective animal husbandry. By protecting your investment from the elements and the animals themselves, you ensure your pigs get the nutrition they need, day in and day out. That simple piece of equipment working in the pasture translates directly to healthier animals and a more sustainable farm.
