Horses are herbivores, which means they only eat plants. Their digestive system is designed to process fibrous plant material, which is why they need a diet that is high in fibre. Horses also require a balanced diet that provides them with all the nutrients they need to maintain good health. This includes carbohydrates, protein, fat, vitamins, and minerals.
The type of food that horses eat depends on a number of factors, including their age, weight, and activity level. In general, horses should be fed a diet that is high in roughage, such as hay or grass. They also require fresh water at all times. In addition to roughage, horses may also be given concentrates, such as grains or pellets, to provide them with extra energy. However, it is important to be careful when feeding concentrates, as too much can cause digestive problems.
Basic Diet of Horses
Forages
Forages are the foundation of a horse’s diet. They provide the necessary fibre that is essential for maintaining a healthy digestive system. Horses require a minimum of 1.5% of their body weight in forage per day. This can be provided in the form of hay, haylage or pasture grass.
It is important to ensure that the forage is of good quality and free from dust and mould. Horses should have access to fresh, clean water at all times.
Concentrates
Concentrates are an important part of a horse’s diet, but they should be fed in moderation. They provide the necessary energy, protein and other essential nutrients that may be lacking in forages.
It is important to choose concentrates that are specifically designed for horses and to feed them according to the horse’s workload and nutritional needs. Overfeeding concentrates can lead to health problems such as colic and laminitis.
When feeding concentrates, it is important to follow the manufacturer’s instructions and to introduce new feeds gradually to avoid digestive upsets.
In summary, horses require a balanced diet that is rich in forages and concentrates. Providing good quality forage and feeding concentrates in moderation can help to maintain a healthy horse.
Feeding Practices
Feeding your horse a well-balanced diet is essential to ensure their health and well-being. In this section, we will discuss feeding schedules and portion sizes.

Feeding Schedule
Horses are natural grazers and require access to forage throughout the day. Ideally, horses should have access to pasture or hay for at least 16 hours a day. If pasture or hay is not available, you can supplement with haylage, chaff, or hay cubes.
It is important to avoid feeding your horse large meals, as this can lead to digestive problems such as colic. Instead, divide their daily intake into smaller, more frequent meals. A good rule of thumb is to feed your horse 1.5-2% of their body weight in forage per day.
Portion Sizes
When it comes to feeding concentrates, it is important to follow the manufacturer’s guidelines and feed according to your horse’s weight and workload. Overfeeding concentrates can lead to weight gain and other health problems.
A general guideline for feeding concentrates is to feed no more than 0.5% of your horse’s body weight in concentrates per meal. For example, if your horse weighs 500kg, they should not be fed more than 2.5kg of concentrates per meal.
It is also important to ensure that your horse has access to clean, fresh water at all times. A horse can drink up to 10 gallons of water per day, so make sure their water source is replenished regularly.
By following a regular feeding schedule and providing appropriate portion sizes, you can help ensure your horse stays healthy and happy.
Nutritional Requirements
To maintain optimal health, your horse requires a balanced diet that provides all the necessary nutrients. These nutrients include vitamins, minerals, and protein. Here are some key points to consider when feeding your horse:
Vitamins
Vitamins are essential for your horse’s overall health. They play a vital role in many bodily functions, including metabolism, immunity, and growth. Horses require both fat-soluble and water-soluble vitamins, which can be found in forage and commercial feeds. Vitamin A, for example, is important for vision and immune function, while vitamin E is an antioxidant that helps protect cells from damage.
Minerals
Minerals are also essential for your horse’s health. They play a crucial role in many bodily functions, including bone development, muscle function, and nerve transmission.
