Do Horses Need Hay If They Have Grass

Do Horses Need Hay If They Have Grass

You might have seen horses grazing peacefully on fresh, green pastures and wondered, do horses really need hay if they have access to all that grass? This is a common question among horse owners, and the answer might not be as straightforward as you'd think. This article provides an in-depth look at the importance of hay and grass in a horse's diet and will help you understand the essentials for maintaining the best possible nutrition for your equine companion.

Horses are natural grazers, and their digestive systems are designed to process forages like grass and hay consistently throughout the day. To understand whether horses need hay in addition to grass, let's break down the nutritional benefits of each.

Grass

Grass is the most natural diet for horses and offers a rich source of essential nutrients, including water, fiber, and vitamins. High-quality pasture grass is a highly palatable feed that satisfies the horse's need to graze and chew, prevents boredom, and reduces the risk of gastric ulcers, colic, and other digestive issues.

Hay

Hay is dried grass harvested and stored for feeding during the winter months or when adequate pasture is not available. It provides the same essential nutrients as grass but is less nutritious due to the loss of moisture and some vitamins during the drying process. Nonetheless, hay is still an excellent source of energy, fiber, protein, and minerals, and can help maintain healthy gut function and weight control in horses.

Now, to the main question: do horses need hay if they have access to grass?

The answer depends on the quantity and quality of pasture grass available, the horse's individual needs, and the time of year.

Horses with 24/7 access to high-quality pasture may not require additional hay during the grazing season (usually spring and summer), as the grass can provide sufficient nutrition and energy for their needs. However, there are some factors to consider:

1. Quantity of grass

Horses should ideally have around 1.5 - 2% of their body weight in forage (grass and/or hay) daily. If the pasture is overgrazed, where little grass remains, extra hay may be needed to compensate.

2. Quality of grass

The nutrient content of grass fluctuates throughout the year, with higher levels in spring and early summer, and lower levels in late summer and autumn. When grass quality declines, additional hay may be necessary for balanced nutrition.

3. Individual horse's needs

The requirements of a grazing horse are different than that of a working one. Pregnant and lactating mares, growing foals, and performance horses may require supplemental hay (or other feeds) to meet their increased nutritional demands, even if they are on the grass.

4. Time of year

During late autumn and winter, when grass growth has slowed or stopped, supplying hay is crucial for horses to maintain their body condition.

Do Horses Need Hay If They Have Grass Example

Imagine a leisure horse with constant access to high-quality pasture during the summer months. It's likely that the horse doesn't need supplemental hay in this situation. However, as the summer ends and the grass quality and quantity decrease, the owner would need to monitor the horse’s body condition and determine if hay should be added to the diet. In this example, the same horse, during winter months with limited access to pasture, would greatly benefit from the addition of hay to maintain optimal weight and health.

In conclusion, whether or not horses need hay when they have access to grass depends on several factors. It's essential to pay close attention to your horse's body condition, monitor the quality and quantity of pasture grass available, and consider the specific needs of your individual horse. By understanding the importance of hay and grass in your horse's diet, you can make informed decisions to ensure their optimal health and well-being.
