Why Goats Chew Troughs: Understanding the Habit

Goats are browsers by nature, driven by an instinct to test, taste, and explore their environment with their mouths. This oral fixation means that anything within reach—fences, shelters, and especially feed troughs—is fair game for a good chew. This behavior is often chalked up to simple boredom, particularly for goats in smaller enclosures with limited forage or environmental enrichment. A smooth, featureless plastic trough can become the most interesting object in their pen.

However, the habit isn’t always about entertainment. Chewing can be a sign of teething in younger goats or a way for the herd to establish a pecking order around a valuable resource. The texture of certain materials might also be satisfying to gnaw on. Understanding this isn’t about stopping the behavior entirely, which is nearly impossible, but about redirecting it by providing equipment that can withstand their relentless curiosity.

It’s crucial not to mistake this normal browsing behavior for a more serious issue right away, but it’s also wise to keep an eye on it. If chewing becomes obsessive and extends to non-food items like rocks or dirt, it could indicate a nutritional deficiency. For most hobby farmers, though, the immediate problem is practical: how to keep a feed trough in one piece for more than a single season.

Key Materials That Stand Up to Goat Chewing

When selecting a trough liner, the material is everything. Not all "durable" materials are created equal when faced with a determined goat. The goal is to choose something that is either too hard to damage or too uninteresting to chew in the first place.

Here are the top material contenders for chew-proof liners:

• Heavy-Duty Rubber: Flexible and forgiving, heavy-duty rubber can absorb the impact of chewing without cracking or shattering like brittle plastic. Goats often lose interest because they can’t get a satisfying "chip" off the material.
• Galvanized Steel: Metal is an obvious choice for durability. The zinc coating on galvanized steel provides rust resistance, and the material is simply too hard for goats to damage with their teeth.
• Stainless Steel: The premium option. Stainless steel is non-porous, rust-proof, and incredibly easy to sanitize. It offers no purchase for chewing and will outlast nearly any other material on the farm.
• High-Density Polyethylene (HDPE): Not all plastics are bad. Thick, food-grade HDPE, often found in heavy-duty stock tanks, is significantly more resilient than the cheap plastic used in standard feed troughs. It resists UV degradation and can handle a lot of abuse.

The key tradeoff often comes down to cost versus longevity. A cheap plastic liner might seem like a good deal until you’re replacing it for the third time in a year. Investing in a quality material from the start saves time, money, and the headache of constantly repairing your feeding setup.

Fortiflex Rubber Pans: A Durable Drop-In Liner

If you need a versatile, no-fuss solution that works in a variety of trough shapes, the Fortiflex Rubber Pan is your answer. Made from a proprietary rubber-polyethylene blend, these pans are designed to be flexible and virtually indestructible. They won’t crack in freezing temperatures or get brittle in the summer sun, which is a common failure point for standard plastic liners.

The real advantage here is the material’s "give." When a goat tries to chew on the edge, the rubber flexes instead of chipping or breaking. This lack of satisfying destruction usually causes them to lose interest and move on. These pans are perfect as drop-in liners for old wooden feeders, metal frames, or even just placed directly on the ground, as their weight and low profile make them difficult to tip.

This is the right choice for the hobby farmer who values simplicity and multi-purpose gear. It’s not a permanent, bolted-in solution, but it’s a tough, portable, and effective liner that can be moved and repurposed as your farm’s needs change. If you want something you can buy today and be using in five minutes, this is it.

Behrens Galvanized Steel Pan for Metal Troughs

For those with existing metal trough frames or a desire for a truly rigid, chew-proof liner, the Behrens Galvanized Steel Pan is a classic for a reason. This is a no-nonsense, heavy-gauge steel pan that simply will not be damaged by chewing. Goats can’t make a dent in it, and its smooth, rolled edge offers no satisfying place to start gnawing.

The primary benefit is its sheer durability. It can handle being kicked, stomped on, and generally abused by even the most boisterous goats. While galvanization provides good rust protection, be aware that scratches from shovels or sharp hooves can eventually compromise the coating, potentially leading to rust over many years. However, for sheer chew-resistance, it’s nearly unmatched in its price range.

This liner is for the farmer who wants a semi-permanent solution for a standard-sized trough. If you have a metal hay-and-grain feeder and are tired of replacing the flimsy plastic insert, a Behrens pan is the perfect, rugged upgrade. Just be sure to measure your trough frame carefully to ensure a snug fit.

Tuff Stuff KMT100: A Heavy-Duty Plastic Option

Don’t let the word "plastic" fool you—the Tuff Stuff KMT100 stock tank is in a different league from typical flimsy trough liners. Made from thick, impact-resistant, high-density polyethylene, this tank is built to withstand the rigors of farm life. Its walls are substantially thicker than a standard feeder, making it incredibly difficult for a goat to get enough leverage to chew through it.

The smooth, rounded lip is a key design feature. It’s too wide and slick for most goats to get a good grip, deterring the chewing habit from the start. As a standalone trough or a drop-in liner for a large wooden or concrete bunk, it offers excellent UV resistance and is chemically neutral, ensuring it won’t leach anything into feed or water.

This is the ideal option for someone needing a large-capacity, durable plastic trough that can double as a water tank or kidding pen feeder. If you prioritize versatility and want a product that is lighter than rubber or metal but far tougher than standard plastic, the Tuff Stuff tank is a solid, long-term investment.

Rust-Oleum EpoxyShield for Concrete Troughs

If you have existing concrete feed bunks, your problem isn’t just chewing—it’s also about hygiene and degradation. Rust-Oleum EpoxyShield Garage Floor Coating offers a unique and highly effective solution. This two-part epoxy creates a hard, non-porous, and seamless surface over the concrete, effectively sealing it from moisture and bacteria.

Once cured, the epoxy finish is incredibly tough and slick. Goats find it impossible to chew because there are no edges or imperfections to grab onto. More importantly, the non-porous surface prevents feed from getting ground into the concrete, which dramatically reduces the growth of mold and bacteria. This makes cleaning as simple as a quick spray with a hose, a major time-saver on a busy farm.

This is a specialized solution for farmers with permanent concrete infrastructure. If you’ve built or inherited concrete troughs and are struggling with cleaning and surface damage, applying an epoxy coating is the single best upgrade you can make. It solves the chewing problem while vastly improving herd health and hygiene.

Commercial Stainless Steel Steam Table Pan Insert

For the hobby farmer who prioritizes absolute hygiene and lifetime durability, a commercial stainless steel steam table pan is an unconventional but brilliant choice. These pans, designed for restaurant use, are made from high-quality, non-porous stainless steel. They will never rust, chip, or leach anything into the feed, making them the safest and cleanest option available.

The perfectly smooth surface and rounded edges offer zero purchase for a chewing goat. They are also incredibly easy to clean and sanitize—a quick scrub and they look brand new, which is a major advantage for feeding minerals, supplements, or wet mashes. While they aren’t designed as trough liners, their standardized sizes make it easy to build a simple wooden frame to hold them securely.

This is the ultimate solution for the health-conscious farmer who wants a "buy it for life" mineral or grain feeder. If you’re tired of worrying about plastic degradation or rust and are willing to do a little DIY framing, a stainless steel pan provides a level of cleanliness and durability that no other material can match.

How to Properly Secure Your New Trough Liner

Simply dropping a new liner into a trough frame is asking for trouble. A bored goat will see the gap between the liner and the frame as a challenge, working tirelessly to pry it out, flip it over, and generally make a mess. Properly securing the liner is just as important as choosing the right material to begin with.

For rigid liners like steel or heavy-duty plastic, the best method is to bolt them directly to the frame. Drill holes through the lip of the liner and the trough frame, then use short carriage bolts with the smooth, rounded head on the inside. This prevents goats from catching themselves on sharp bolt ends. Using washers will help distribute the pressure and prevent cracking.

For flexible rubber pans, securing the edges is key. You can use wide-headed roofing screws with a neoprene washer to fasten the lip of the rubber pan to the top of a wooden trough. For a less permanent solution in a metal frame, heavy-duty zip ties or wire can be looped through drilled holes to hold it in place. The goal is to eliminate any lip or edge that a goat can get its mouth under.

Pica in Goats: Is Chewing a Mineral Issue?

While boredom and curiosity are the most common culprits, persistent and unusual chewing can sometimes be a sign of a deeper issue. Pica is a condition where animals crave and eat non-food substances like dirt, rocks, wood, or plastic. This behavior is often linked to a mineral or vitamin deficiency in their diet.

If you notice a goat is obsessively chewing its trough liner—or the fence posts, the barn walls, and everything else—it’s time to evaluate your mineral program. Goats have complex nutritional needs, and a simple salt block is rarely sufficient. A high-quality, loose mineral mix formulated specifically for goats should be available free-choice at all times. Ensure the mineral feeder is clean, dry, and always full.

Addressing a potential mineral issue is a critical part of holistic herd management. While a chew-proof trough solves the immediate equipment problem, it doesn’t solve the underlying health issue if one exists. Paying attention to behavior is key; a destructive goat might just be a bored goat, but it could also be telling you something important about its nutritional well-being.

Cleaning and Maintaining Chew-Proof Troughs

Investing in a durable trough or liner is only half the battle; proper maintenance ensures it lasts a lifetime and keeps your herd healthy. The material of your trough will dictate the best cleaning method. For stainless steel, galvanized steel, and epoxy-coated concrete, cleaning is straightforward. A stiff brush and water are usually enough to remove leftover grain and grime. Their non-porous surfaces resist bacterial growth, making sanitation simple.

Rubber and heavy-duty plastic troughs require a bit more attention. While durable, their surfaces can develop micro-scratches over time that can harbor bacteria. A regular scrub with a brush and a mild dish soap or a vinegar solution is recommended, followed by a thorough rinse. Avoid using harsh chemicals like bleach, which can degrade the material over time and be harmful if not completely rinsed away.

For any metal trough, the biggest long-term enemy is rust. Even galvanized steel can begin to rust if the protective zinc coating is deeply scratched. Inspect metal troughs periodically for deep gouges, especially if you use a metal shovel to scoop out old feed. Addressing scratches early with a food-safe, rust-inhibiting paint can significantly extend the life of your investment.

Ultimately, choosing the right trough liner is about matching the right material to your specific needs, herd size, and infrastructure. By investing in a durable, well-secured solution, you can finally put an end to the cycle of broken feeders. This frees up your time and resources to focus on what really matters: raising healthy, thriving goats.
