Livestock management is a complex task that demands a comprehensive understanding of many variables, including animal behavior, health requirements, and diet. One particular area of interest for ranchers, feedlot managers, and others involved in the cattle industry is the dietary habits of cows and the effects of certain types of fodder on their health.

In this guide, we will delve into cows eating clover, elucidating why it can be harmful and what ranchers can do to prevent any associated health issues.

Understanding the Cow’s Diet

Understanding the intricacies of a cow’s diet is pivotal to successful livestock management. A cow’s digestive system is built for foraging on various plant materials. Thus, their diet should be a mix of grasses, legumes, and a small amount of grains.

Cows are ruminants with a unique four-chambered stomach designed to extract nutrients from plant-based food through fermentation. The largest of these chambers, the rumen, plays a vital role in breaking down complex plant materials, such as cellulose, into simple compounds. This process allows cows to derive nutrition from foods that other animals may be unable to digest.

A balanced cow’s diet comprises proteins, energy, vitamins, minerals, and water. Proteins are needed for growth, production of milk, and maintenance of bodily functions. Energy, derived from carbohydrates in the feed, fuels all these processes. Minerals and vitamins are essential for a wide range of physiological functions, while water, often overlooked, is crucial for digestion, nutrient transportation, and temperature regulation.

Knowing the basics of a cow’s diet enables you to make informed decisions on feeding strategies, ensuring your herd’s nutritional needs are met while minimizing the risk of dietary-related health issues. Balancing these dietary elements can significantly contribute to overall herd health, productivity, and, ultimately, the farm’s profitability.

Characteristics of Clover

Clover is a member of the legume family and is highly prevalent in pastures worldwide. It is a plant that is high in protein and provides essential nutrients. Its value in livestock diets has long been recognized due to its high digestibility and palatability to animals. However, certain aspects of clover can make it a risk factor for cows’ health if ingested in significant quantities.

Identifying Clover Varieties in Your Pasture

Understanding the types of clover present in your pastures is the first step towards managing their potential effects on your cattle’s health. Different clover varieties, such as red clover, white clover, alsike clover, and sweet clover, all have distinctive characteristics and potential impacts on cattle. For instance, red and alsike clover has been known to cause bloat, while white clover is generally safer. Engage with local agricultural extension services or agronomists to help identify the types of clover in your pastures, and use this knowledge to inform your grazing strategies and management practices.

Why Do Cows Eat Clover?

Nutritional Value of Clover for Cows

As a legume, clover is packed with protein, fiber, and a range of essential vitamins and minerals. It’s an excellent source of readily digestible energy for cows, and because of its high nutritional content can contribute to their weight gain, milk production, and overall health.

Behaviors and Preferences of Cows

Cows, like many other animals, have preferences regarding their diet. They tend to gravitate toward plants that are palatable and offer nutritional benefits. Clover fits this bill due to its sweet taste and high nutritional content, making it a preferred choice for cows when available.

This understanding of the cow’s diet and why cows may be inclined to eat clover sets the groundwork for exploring the potential hazards of clover consumption. Although it may seem counterintuitive that something as nutritious as clover could pose a risk, the reality is a bit more complicated. In the following sections, we will unpack the potential dangers of eating clover, delve into clover disease, and discuss the most significant concern: bloat. We will also dispel some common myths and recommend maintaining a balanced and safe diet for your cows.

Transitioning Cows to Clover-Rich Pastures

Transitioning cows gradually to clover-rich pastures can help avoid sudden changes in their diet, reducing the risk of digestive complications like bloat. Start by allowing cows to graze on clover for short periods, gradually increasing the duration over a few weeks. During this period, closely monitor their health and behavior for signs of discomfort or bloating. It’s also beneficial to ensure that cows have access to dry hay during the transition, which can help to stabilize their rumen function.

Potential Dangers of Eating Clover

Components of Clover Which Cause Harm

While clover is a nutrient-rich forage, certain compounds can harm cattle health. Specifically, it contains condensed tannins, a group of polyphenolic compounds that can reduce the digestibility of protein and other nutrients in ruminants. Another harmful component of clover is a compound known as coumarin, which can be converted to a toxic substance called dicoumarol when the clover becomes moldy or ferments.

The Role of Microbes in Ruminant’s Digestive System

The cow’s rumen, the most significant part of its stomach, houses a vast ecosystem of microbes that aid in the digestion of food. However, gas can be a by-product when these microbes ferment the clover. When cows consume a large amount of clover, this gas production can become excessive, leading to a condition known as bloat.

Implementing Sustainable Grazing Practices

Sustainable grazing practices are essential in maintaining the balance of various forage types in your pastures. Rotational grazing, for instance, involves moving cattle regularly between pasture sections. This allows forage to recover after grazing, promoting biodiversity and reducing the overconsumption of specific plant types such as clover. Another technique, strip grazing, restricts cows’ access to a small portion of the pasture at a time, preventing them from selectively overgrazing on clover.

Clover Disease in Cows

Symptoms of Clover Disease

Ingesting moldy clover-containing dicoumarol can lead to a condition commonly known as “sweet clover disease.” Blood clotting issues characterize this ailment. Symptoms include swelling of tissues, hemorrhages into tissues throughout the body, and severe blood loss after minor injuries. Pay close attention to your cattle and promptly seek veterinary attention if such signs are observed.

Treatment and Management of Sick Cows

Sweet clover disease can be life-threatening and should be treated promptly. Treatment typically involves providing the cow with Vitamin K, which aids blood clotting. It’s best to avoid feeding your cows with moldy sweet clover hay or ensilage to prevent this disease. Regularly checking and maintaining the quality of stored fodder can save you from potential livestock health hazards.

Bloat in Cows- The Main Danger of Eating Clover

Understanding Bloat: Causes and Symptoms

Bloat, also known as ‘frothy bloat,’ is a condition characterized by the accumulation of gas in the cow’s rumen to the point where it can’t be expelled. It’s mainly caused by consuming certain legumes, such as clover, in excessive quantities. Symptoms of bloat include a distended left side (due to the location of the rumen), discomfort, and labored breathing.

Treating and Preventing Bloat in Cows

Bloat can be severe and needs immediate treatment, usually involving administering anti-foaming agents and sometimes even emergency surgery. Preventive strategies include managing the cow’s diet to ensure that it doesn’t overeat on clover and using feed additives that can help control the gas production in the rumen.

Integrating Clover with Other Forages for a Balanced Diet

Integrating clover with other forages in your pastures can lead to a more balanced and nutritious diet for your cows. Consider planting a mix of grasses and legumes in your pastures to provide a variety of nutrients and to dilute the quantity of clover that cows consume. This can be achieved through over-seeding existing pastures or establishing new ones with a carefully chosen seed mix. This practice can improve the nutritional quality of the forage and decrease the potential risk associated with excessive clover consumption.

Common Myths About Cows and Clover

The Truth About Clover and Cow

One common myth is that all clover is harmful to cows. In reality, not all types of clover pose a risk. For instance, white clover rarely causes bloat. Therefore, it’s essential to distinguish between different clover varieties and manage their proportion in pastures.

Economic Impact of Clover Consumption on Cows

Health issues related to excessive clover consumption, such as bloat or sweet clover disease, can have significant economic consequences. These can include the cost of veterinary treatments, loss of productivity, and in severe cases, the loss of animals. By managing the amount of clover in pastures and implementing preventive measures, farmers can reduce these risks and associated costs. The economic viability of a farm is closely tied to the health and productivity of its livestock, underlining the importance of proper diet management.


Our comprehensive exploration of cows and their interaction with clover leads to several key takeaways.

Clover’s Role in a Cow’s Diet

Clover can form a valuable part of a cow’s diet due to its high nutritional value. It offers essential nutrients such as protein and minerals for cows’ health and productivity. However, while clover has benefits, it should not make up most of a cow’s diet. Careful moderation and balanced intake are essential to prevent potential health issues.

The Dangers of Overconsumption

While clover is not intrinsically dangerous, its overconsumption can pose significant health risks to cows. The main risk of consuming large amounts of clover is bloat, a potentially life-threatening condition caused by gas build-up in a cow’s rumen. Sweet clover disease, a bleeding disorder caused by moldy sweet clover, is another significant risk associated with excessive clover consumption.

Balancing the Cow’s Diet

A balanced diet for cows is essential to livestock management. Rather than relying heavily on clover, farmers should aim to provide a variety of forages in their pastures. Integrating clover with other forage types, such as grasses and legumes, helps balance the diet and dilutes the clover intake, minimizing the risk of health issues related to overconsumption.

Managing Clover Consumption

There are several strategies farmers can employ to manage clover consumption in their herds. One effective way is to transition cows gradually to clover-rich pastures, which can help their digestive systems adjust to the change in diet. Implementing sustainable grazing practices such as rotational or strip grazing can also help manage clover intake. Additionally, regular health check-ups for the herd can aid in early detection and intervention of potential health issues.

The Economic Impact

The economic implications of health issues caused by excessive clover consumption can be substantial. These can include veterinary costs for treating affected animals, loss of productivity due to ill health, and in severe cases, loss of livestock.
