Summer brings longer days, warmer temperatures, and often an increase in the level of activity for horses. Whether your horse is in light work, competing, or enjoying some downtime, it’s important to adjust their diet during the summer months to keep them healthy, hydrated, and performing at their best. Here’s how you can feed your horse effectively during the hot summer season.
1. Provide plenty of fresh, clean water
First and foremost, hydration is key to a horse’s wellbeing, especially in the summer. Horses can sweat a lot in the heat, which leads to water loss. Ensure your horse has access to clean, fresh water at all times. Check water sources regularly for cleanliness and make sure there are no obstructions that might prevent them from drinking. Offering water multiple times a day, particularly after exercise, will help maintain hydration.
2. Adjust forage intake
Forage is an essential part of a horse’s diet, but during the summer, it’s crucial to manage forage intake properly. When grazing on fresh pasture, horses may need less additional forage. However, if pasture grass is sparse or if you’re stabling your horse, you should ensure they still get a good amount of fibre in the form of hay or chaff.
If your horse is overweight or not working hard during the summer, you may want to reduce the additional forage amount. Conversely, a horse that is working harder or underweight may need additional hay or chaff to keep up their energy levels.
3. Focus on quality pasture
Summer is often a great time for pasture grazing, but the quality of the pasture can vary. Ideally, your horse should have access to high-quality grass that is free of toxic plants. Make sure that the pasture isn’t overgrazed, as this could cause your horse to consume less nutritious, tougher grasses. It's important to monitor pasture intake to prevent overgrazing, which can lead to colic or laminitis, especially in horses that are prone to metabolic issues.
In areas where the grass quality is poor or there’s a lack of pasture space, supplemental feeding can be a good option.
4. Monitor grain and supplementation
During the summer months, many horses' energy needs decrease, particularly if their workload is lighter or if they’re getting plenty of nutrients from pasture. However, performance horses or those in more intensive training may require grain to supplement their energy intake.
Grains should be fed carefully, and it’s best to provide them in smaller, more frequent meals rather than one large serving to prevent digestive upset. Don't forget to balance them with additional forage for a nutritious feed.
Additionally, consider the type of grain you’re offering. Some horses may benefit from a grain mix that includes electrolytes to replace those lost through sweat. Be sure to consult with your vet or nutritionist for guidance on the best feeding regime for your horse's individual needs.
5. Consider electrolyte supplements
Sweating causes horses to lose not just water, but important electrolytes like sodium, potassium, and chloride. During the hot summer months, adding an electrolyte supplement to your horse’s diet may help replenish these essential minerals. These supplements can be mixed with feed or provided in the form of oral pastes or drinks. Be sure to follow the recommendations on the product packaging or your veterinarian’s guidance, as over-supplementation can lead to other issues.
6. Feed at cooler times of the day
Feeding your horse during the heat of the day can be less than ideal, as they may be less interested in eating or drinking when temperatures are high. It's best to feed your horse early in the morning or in the evening when it’s cooler. This not only helps with appetite but also reduces the risk of digestive issues like colic, which can be aggravated by high heat.
7. Monitor for weight changes
Finally, it’s important to regularly assess your horse’s body condition during the summer months. Heat and humidity can cause horses to lose weight or become dehydrated, especially if they are in heavy work. Regularly check their weight, coat condition, and hydration levels, and adjust their diet as needed to keep them in top shape.
Feeding horses effectively during the summer months requires careful attention to hydration, pasture quality, hay management, and the balance of grain, additional forage and supplements. By adjusting their diet to the demands of warmer weather and monitoring their health closely, you can ensure that your horse remains healthy, comfortable, and ready to take on the summer season.
