Winter Feed and Nutrition: Adjusting Your Horse's Diet for Winter

As the chilly winds pick up, we can be sure that Australian winter is in full swing.

So what does winter mean for our horses' diet and nutrition? It becomes essential to adjust your horse's diet to ensure they receive optimal nutrition and maintain their health throughout the cooler months.

Winter horse nutrition plays a vital role in supporting not only their energy levels, but their immune system, and overall well-being during the colder months. We don’t quite alter their diets the same way that we might throughout winter, with warm soup and hot toast, but we are going to break down the important steps in assessing your horse's nutritional needs.

In this guide, we will explore the key considerations for adjusting your horse's diet, including forage options, essential nutrients, and supplemental feeding strategies for winter. By understanding how to provide the right nutrition for your horse during the colder season, you can keep your horses healthy and thriving all winter long.

Assessing Nutritional Needs

Before making any adjustments to your horse's diet, it is crucial to thoroughly assess their individual nutritional requirements, as this will vary from horse to horse.

Be sure to take  into account factors such as age, weight, workload, and overall health. Looking at all these factors will allow you to provide targeted nutrition for your equine/s.


Considering your horse's age when determining their nutritional needs is an important step!

Younger horses, such as foals or growing yearlings, have higher requirements for energy, protein, and minerals to support their development. Older horses, on the other hand, may have specific dietary needs to address age-related conditions such as dental issues or metabolic changes.



Evaluating your horse's body condition and determining if they are at an ideal weight can help you to understand if they are underweight, overweight, or at an appropriate weight. From there, you can adjust their diet accordingly to support weight gain, weight loss, or weight maintenance - depending on what is required for your horse.. Keep in mind that weight loss or gain can occur due to various factors, not solely due to the cold weather.



The level of exercise or work your horse undergoes during winter affects their nutritional requirements. Horses with higher activity levels will require additional energy and nutrients to support their increased metabolism and muscle function. 

Adjust the diet accordingly by incorporating higher-calorie feeds or increasing the quantity of grain or concentrates, if necessary.


Overall Health:

Consider your horse's overall health when assessing their nutritional needs. Horses with certain medical conditions, such as metabolic disorders or gastrointestinal issues, may require specialized diets or specific feeding strategies during winter. Consult with a veterinarian or equine nutritionist to develop an appropriate dietary plan for horses with specific health concerns to ensure peak health and nutrition.


Grazing Conditions:

Australian winters can vary significantly in terms of temperature and rainfall, which can impact grazing conditions and nutrient availability. Monitor the quality and quantity of pasture available to your horse.

Areas of sparse or nutrient-deficient pastures may require additional nutritional supplementation to meet your horse's requirements. If grazing is limited, providing good quality hay becomes even more important to ensure adequate fibre intake.

We would always recommend consulting your veterinarian or equine nutritionist when assessing your horse's nutritional needs. These professionals will be able to conduct a thorough evaluation to paint a larger picture of your horse's needs and undertake relevant testing to align with this. 

Keep in mind that your equine’s nutritional needs can change over time, so it’s important to regularly reassess them and adjust their diet accordingly.

Winter Forage Options

As you'll know, forage serves as the foundation of a horse's diet, even during winter. While grazing may become limited during the colder months, it's important to still be providing good quality forage to meet your equine's dietary fiber needs.

Hay is the primary source of forage in winter, and Australian horse owners have various options available, such as lucerne (alfalfa), clover, or grass hay. Each type has its own nutritional profile, so choose one that best suits your horse's requirements and availability in your area. Take into consideration your horses health and nutritional needs when choosing forage that is suitable and will tick all the boxes.

During winter, horses tend to spend more time indoors or in their paddocks with limited grazing. In these cases, slow feeders can help simulate natural grazing patterns and provide continuous access to forage. This helps prevent boredom, reduces the risk of digestive issues, and ensures your horse receives sufficient fiber intake throughout the day.

Essential Nutrients for Winter

In addition to forage, horses require specific nutrients to thrive during winter.

Just like humans, adequate protein, vitamins, minerals, and fats are essential for maintaining body condition, supporting the immune system, and promoting overall health. Balancing your horse's diet with appropriate nutrient ratios is crucial.


Ensure your horse receives adequate protein to support muscle maintenance and repair. Protein is an essential nutrient for horses, playing a crucial role in muscle maintenance, growth, and repair. During the Australian winter, it is important to ensure that your horse receives adequate protein to support their overall health and well-being.

Good sources of protein include high-quality hay, legume forage, and commercial protein supplements formulated for horses.


Vitamins and Minerals:

We all know that vitamins and minerals are an important factor in health care. We're constantly having this drilled into us for our own wellbeing, and the same goes for our horses. 

Vitamins and minerals are an essential part of your horses' healthcare as they play a vital role in supporting their overall health and well-being. 

Throughout winter, the availability of certain vitamins and minerals in forage may be affected. This can be affected by factors such as the soil quality, weather conditions, and storage methods. For this reason, it's more important than ever to assess the nutrient content in your horses hay or pastures to identify any deficiencies. This will allow you to ensure that their dietary needs continue to be met.



Fats play a crucial role in your horse's diet, providing a concentrated source of energy and contributing to overall health and well-being. Including fat sources in your horse's winter diet can help maintain a healthy body condition and provide additional calories to support their energy requirements.

During Australian winter, horses may experience increased energy demands due to factors such as cold temperatures, maintaining body warmth, and potentially engaging in higher levels of physical activity. Including fat sources in their diet can help meet these increased energy needs without relying solely on high-starch grain-based feeds, which can be challenging for some horses to digest.

Vegetable oils, such as soybean oil, corn oil, or flaxseed oil, are commonly used fat sources in horse nutrition. These oils are rich in omega-6 and omega-3 fatty acids, which are beneficial for overall health. Omega-3 fatty acids, in particular, have anti-inflammatory properties and can support immune function.

Feeds containing omega-3 fatty acids, such as flaxseed (linseed) or chia seeds, can also be incorporated into your horse's diet. These feeds provide not only fat but also other important nutrients, such as protein and fiber. However, it's essential to introduce these feeds gradually to allow your horse's digestive system to adjust.


Supplement Feeding Strategies

In certain situations, horses may require additional nutrition beyond forage. This is particularly relevant for horses with higher energy demands or those with limited grazing opportunities during winter.

You might want to consider the below options if this seems relevant to your horses and environment.

Grain and Concentrates:

If your horse's workload increases during winter, consider incorporating grains or concentrates into their diet. However, be cautious with grain intake and ensure it is balanced with forage to prevent digestive disorders. Consult with an equine nutritionist to determine appropriate quantities and types of grains for your horse.

While winter in Australia may not be as hot as other seasons, it is still important to monitor your horse's hydration levels. Electrolyte supplementation can help maintain proper hydration and electrolyte balance, especially if your horse is exercising or sweating more. Consult with a veterinarian or equine nutritionist to determine the most suitable electrolyte supplement for your horse if you are not familiar with the use of electrolytes.


Monitoring Body Condition

Throughout the winter season, we know how important adequate and correct nutrition is, but it is also crucial to be regularly checking and monitoring your horse's body condition to ensure that they are maintaining a healthy weight.

When taking into consideration your horse's body condition, it will allow you to understand whether or not their diet needs to be adjusted whilst also allowing you to keep an eye on their overall health.

Weight loss or gain may be more prevalent throughout the colder months, but it's important to monitor body changes to be sure that the root cause can be identified and acted upon. Whilst weight loss and gain can be attributed to cold weather, other factors such as dental health and underlying medical conditions could also play a huge role in this.

It's super important to always consult a veterinarian if you notice significant changes in body condition, any time of the year!
