Why Do Cows Eat Wood Fence?

Why do cows eat wood fence? It may seem puzzling and even absurd, but the reality is that sometimes, cattle exhibit a peculiar behavior of chewing on bark and wooden fences, as well as feed bunks. This behavior, known as pica, occurs when animals seek or try to consume substances that aren’t part of their usual diet. While it may seem odd, there are various reasons why cows engage in this behavior. One possible explanation is that they do it out of boredom, as they may lack stimulation or entertainment in their environment. Additionally, some cows may consume wood because of a nutrient imbalance in their diet, leading them to seek alternative sources of nutrients. Understanding why cows eat wood fence requires delving into the complex behavioral and nutritional aspects of these animals, shedding light on their unique and sometimes perplexing habits.

Why Would a Cow Eat Wood?

Why would a cow eat wood? Sometimes, cattle get — for lack of a better word — bored and will chew on bark and wooden fences and feed bunks. Seeking or trying to consume something that isn’t considered “normal” food for the animal in question is called pica. Sometimes, animals seek wood because of a nutrient imbalance.

Cows, like humans, can experience moments of restlessness or ennui, particularly if they’re confined to small spaces or have limited access to stimulating environments. In such cases, chewing on wood or other non-food materials can serve as a form of mental stimulation or entertainment. This behavior can be observed in both domesticated and wild cows, although it’s more commonly seen in intensively managed agricultural settings.

It’s worth noting that wood ingestion can be harmful to cows. Splinters and other sharp objects in the wood can also cause injury or infection. Therefore, it’s essential for farmers and caretakers to provide cows with an appropriate and nutritionally balanced diet, as well as ample opportunities for exercise and mental stimulation, to prevent them from resorting to wood consumption.

Nonetheless, this behavior can be detrimental to their health and well-being. It’s crucial for farmers and caretakers to address the root causes of wood consumption by ensuring proper nutrition and providing a stimulating environment for the animals.

While understanding which plants repel cows can be helpful in keeping them away from certain areas, another effective method for fencing off boundaries is electric fences. Solar-powered electric fences provide a cost-effective solution for enclosing a substantial length of land. However, it’s essential to note that cows naturally avoid plants like Mint, Sage, Mexican bush sage, Oleander, Firethorn, Pyracantha, and Azalea, making these plant choices suitable for deterring them.

What Plants Repel Cows?

Cows, being herbivores, often graze on a variety of plants and vegetation. However, there are certain plants that are known to repel cows and deter them from approaching or consuming them. Understanding which plants have repellent effects on cows can be useful for farmers and landowners in managing their livestock and protecting specific areas from grazing.

One plant that’s known to repel cows is mint. The strong aroma and taste of mint can be unpleasant for cows, causing them to avoid areas where this plant is present. Similarly, sage, particularly Mexican bush sage, has repellent properties that can deter cows. The strong scent of sage can act as a natural deterrent, making cows less likely to graze on it.

Oleander is another plant that cows tend to avoid. This flowering shrub contains toxic compounds that are harmful to livestock if ingested. Similarly, firethorn, also known as Pyracantha, possesses sharp thorns and bitter-tasting berries that discourage cows from consuming it.

Azalea, a popular ornamental flower, is another plant that can repel cows. The presence of certain toxic compounds in azaleas can be detrimental to cows if ingested. This knowledge can be valuable for landowners who wish to protect their azaleas from grazing animals.

Some cows may still consume these plants if there are no other available food sources.

The use of solar-powered electric fences is a relatively inexpensive option that provides a physical barrier to keep cows away from certain areas and can be easier to install over a significant length of boundary than traditional fencing methods.

In addition to being an economical choice, using wood chips as animal bedding offers various benefits. Research suggests that wood chips can be a viable alternative to straw bedding for beef cattle. Not only does it provide comfort and cleanliness for the animals, but it also contributes to reducing greenhouse gas emissions during the manure handling process.

Can Wood Chips Be Used for Animal Bedding?

Wood chips can indeed be used as an alternative to straw bedding for beef cattle, offering a cost-effective solution for farmers. Research has shown that wood chips provide a comfortable and clean environment for the cattle, ensuring their well-being. Additionally, utilizing wood chips as bedding can help in reducing greenhouse gas emissions during the manure handling process.

Instead of using straw, which often requires high labor inputs to harvest and process, wood chips can be sourced from sustainable forestry practices. This not only reduces the carbon footprint associated with bedding production but also supports responsible land management.

They’ve a longer lifespan compared to straw, as they take longer to decompose. This means that less frequent bedding replacements are needed, saving time and effort for farmers.

They provide comfort and cleanliness for the animals, while also offering benefits in terms of reduced greenhouse gas emissions and improved nitrogen management.

In addition, cows primarily rely on grazing grass and other forage rather than consuming tree leaves as a significant part of their diet.

Do Cows Eat Leaves Off Trees?

This means that cows can’t fully extract nutrients from leaves and they often pass through their digestive system undigested. In general, cows prefer to graze on grass and other vegetation that’s easily digestible and provides them with the necessary nutrients for their diet.

However, there are instances where cows may eat leaves off trees, such as during periods of scarcity or when they’re confined in an area with limited access to other types of forage. This behavior is more commonly observed in pasture-based systems where cows have the freedom to browse on a variety of plant materials.

It’s also worth noting that cows have a natural inclination to explore and taste different objects in their environment. This includes not only leaves off trees but also things like wood fence posts. This behavior is known as “pica” and is believed to be influenced by factors such as mineral deficiencies, boredom, or a lack of appropriate forage.

Their digestive system is better suited for breaking down and extracting nutrients from grasses and other herbaceous plants. Additionally, cows have evolved to be efficient grazers and have specialized teeth and a complex four-chambered stomach that enables them to effectively process and obtain nutrients from plant material.

The Importance of Diverse Forage in Cattle Grazing Systems

  • Diverse forage is vital for cattle grazing systems
  • It helps to provide a balanced diet for the cattle
  • Different forage types offer varying nutritional values
  • Having a variety of forage ensures cattle receive essential nutrients
  • Diversity in forage can improve cattle health and productivity
  • It helps to prevent overgrazing and nutrient depletion in pastures
  • Various forage options also promote biodiversity in grazing areas
  • Cattle that consume diverse forage tend to have better body condition
  • Different forage types also impact the flavor and quality of beef
  • Incorporating various forage options is essential for sustainability
  • Diverse forage allows cattle to have choices and exhibit natural behavior

Cows’ unusual preference for sawdust might seem puzzling at first, given it’s indigestible nature. However, recent experiments have revealed a fascinating solution to this mystery. By treating the sawdust with nitric acid to break down the lignin, a compound that inhibits digestion, researchers found that cows suddenly found the processed sawdust to be distinctly appetizing. Such unexpected findings offer further insight into the complex dietary preferences of these gentle giants.

Why Do Cows Like Sawdust?

Cows have a peculiar taste for the unconventional, and one of their favorites happens to be sawdust. But why do these herbivorous creatures find pleasure in munching on this woody material? The answer lies in the composition of sawdust. This material is primarily made up of cellulose, a carbohydrate that provides energy. However, it’s also bound together with lignin, a compound that makes it difficult for cows to digest.

To make sawdust more palatable for these bovine creatures, researchers like Batey have experimented with various methods. Batey soaked some of the sawdust in nitric acid, which stripped away the lignin and made it easier for cows to consume. In fact, Batey recalls the cows relishing their newfound delight, proving that their preferences can extend beyond traditional fodder.

Furthermore, cows digestive systems are remarkably adaptable. Their rumens, a specialized stomach compartment, house a complex microbial community that aids in the breakdown of food. This community can adjust to different types of plant material, accommodating the digestion of sawdust as well.

It highlights their ability to explore and adapt to different food sources, even if they may not conventionally be considered suitable for consumption. So next time you spot a cow munching on a wood fence, remember that their taste buds might just be seeking a new and intriguing flavor experience.


While it may seem incomprehensible, it’s important to remember that animals, like humans, can experience instances of boredom and may engage in unconventional behaviors as a result. This includes chewing on bark and wooden fences and feed bunks, a form of behavior known as pica. Although this behavior may appear puzzling, it serves as a reminder that animals, just like us, have unique quirks and preferences that may not always align with their prescribed diets.
