Horse not Eating Hay Overnight? Reasons and Solutions

Horse owners understand the importance of monitoring their horse’s eating habits, as changes in these habits can indicate potential health problems or stressors. One issue that may be of concern is when a horse does not eat its hay overnight.

In this article, we will explore the possible reasons behind this behavior, potential health issues that may arise, and the steps owners can take to address the issue.

Why is Horse not Eating Hay Overnight?

If a horse is not eating hay overnight, it could be due to dental issues, a sudden transition between pasture and hay, or a preference for fresh, high-quality hay. Addressing these issues and offering a variety of hay may help encourage the horse to eat hay during the night.

Reasons for Horses Not Eating Hay Overnight

Horse not Eating Hay Overnight

1. Full from Daytime Grazing: If a horse spends a significant portion of the day grazing in the pasture, it may consume enough grass to feel full and satisfied by the time it is brought into the stable for the night. As a result, the horse may not feel the need to consume additional hay overnight, even if it is provided.

2. Dental Problems: Dental issues can make it difficult for a horse to chew hay, leading to a decrease in hay consumption. Overgrown or sharp teeth can cause discomfort or pain while eating, resulting in the horse avoiding hay altogether.

3. Sudden Diet Changes: If a horse’s diet is suddenly changed, it may take some time for the horse to adjust to the new food. This may be particularly true if the hay is a different type or quality than the horse is used to.

4. Poor Hay Quality: If the hay provided is of poor quality, moldy, or contaminated, a horse may refuse to eat it. Horses have a keen sense of smell and can detect when hay is not fresh or suitable for consumption.

Potential Health Issues


Colic is a term used to describe abdominal pain in horses and can be caused by several factors such as gas buildup, impaction, or twisting of the intestines. If a horse is not eating hay overnight, it may be at an increased risk of developing colic due to the lack of consistent fiber intake.

Signs of colic include pawing at the ground, rolling, looking at or biting the abdomen, and a lack of appetite. If you suspect colic, it is important to contact your veterinarian immediately, as it can be a life-threatening condition if left untreated.

Gastric Ulcers

Gastric ulcers occur when the lining of the horse’s stomach becomes eroded, leading to discomfort and pain. Ulcers can be caused by various factors, including stress, irregular feeding schedules, or excessive use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Symptoms of gastric ulcers include weight loss, poor appetite, irritability, and changes in behavior.


Dehydration in horses can occur due to inadequate water intake or excessive fluid loss through sweat, urine, or diarrhea. Dehydration can lead to a variety of health problems, such as impaired digestion, electrolyte imbalances, and an increased risk of colic.

Symptoms of dehydration include sunken eyes, dry or tacky gums, and poor skin elasticity. To prevent dehydration, always ensure that your horse has access to clean, fresh water, and monitor their water consumption closely.

Addressing the Issue of Horses Not Eating Hay Overnight

Understanding and addressing the issue of horses not eating hay overnight is crucial to ensure their overall health and well-being. There are several factors to consider and steps to take in order to encourage horses to consume hay during nighttime hours.

Ensure Proper Dental Care

One of the primary reasons that horses may not be eating hay overnight is due to dental issues. Regular dental check-ups and maintenance are essential for horses, as poor dental health can cause discomfort, pain, and difficulty in chewing hay.

Schedule routine dental examinations with an equine veterinarian, and address any dental issues promptly to ensure that your horse is comfortable and able to consume hay effectively.

Gradually Transition Between Pasture and Hay

Horses that spend their days grazing on pasture may be less inclined to eat hay overnight. To minimize the risk of digestive issues and encourage hay consumption, it is essential to gradually transition your horse between pasture and hay.

Over the course of several days, gradually increase the amount of hay offered while decreasing the time spent on pasture. This slow transition allows your horse’s digestive system to adapt to the new forage, reducing the risk of colic or other digestive problems.

Offer Fresh, High-Quality Hay

The quality of hay is a significant factor in a horse’s willingness to consume it overnight. Ensure that the hay provided is fresh, free from mold, contaminants, and of high nutritional value.

Horses are more likely to consume hay overnight if it is palatable, appealing, and meets their nutritional requirements. Regularly inspect your hay supply and replace any moldy or spoiled hay immediately.

Provide a Variety of Hay

Offering a variety of hay types can encourage your horse to eat hay overnight. Different types of hay, such as alfalfa, timothy, or orchard grass, provide varying levels of nutrition and taste.

By providing a selection of hay options, you can cater to your horse’s individual preferences and increase the likelihood that they will consume hay during nighttime hours.

Adjust Feeding Schedule

If a horse is not eating hay overnight due to being full from daytime grazing, consider adjusting the feeding schedule. For example, you may want to reduce the amount of pasture time or provide smaller amounts of hay throughout the day and evening to encourage more consistent forage intake


In conclusion, addressing the issue of horses not eating hay overnight is essential for maintaining their overall health and well-being. By ensuring proper dental care, gradually transitioning between pasture and hay, offering fresh, high-quality hay, and providing a variety of hay options, you can encourage your horse to consume hay during nighttime hours and maintain a balanced diet.

Regular monitoring and proactive care can help ensure the health and happiness of your equine companion.
