Healthy Weight Gain for Your Thoroughbred Horse: Tips for Owners

As a Thoroughbred horse owner, one of the biggest concerns you may face is ensuring your horse maintains a healthy weight. Weight issues can be a significant problem, especially if you plan to compete or breed your horse.

However, with the right steps, you can help your Thoroughbred horse gain weight naturally and healthily.

Teeth Issues

Teeth issues are a common problem among horses, and they can be a significant cause of weight loss. When your horse’s teeth become overgrown or misaligned, they may find it difficult to eat properly, leading to weight loss.

To address this issue, you need to have your horse’s teeth examined and “floated” regularly. This process involves filing down any sharp points or overgrowths, creating a smoother surface for the horse to chew on.

Parasite Infestations

Parasite infestations can also be a common cause of weight loss in horses. These gastrointestinal parasites, including worms, can cause malnutrition, reduced appetite, and overall weakness in your horse.

Therefore, it’s important to use a proper worming program and deworm your horse regularly, especially if they are in contact with other horses or graze on contaminated pastures.

Feeding Amounts

Feeding amounts can also play a crucial role in weight gain. Horses require a lot of roughage to maintain their digestive system, and forage should make up the majority of their diet.

However, you need to ensure that your horse is getting enough hay or pasture, as they may not be able to eat enough to keep their weight up.

Activity Level and Feeding

Your horse’s activity level can also play a role in their weight. Athletic horses burn more calories, so if your horse is in training or has a high activity level, they may require more feed to maintain their weight.

Additionally, a consistent and regular feeding regimen can help your horse gain weight, as their digestive system adapts to the rhythm of their diet.

Forage and Hay

Forage and hay are essential to a healthy horse’s diet, and can be an excellent source of weight gain. Ensure that your horse has free access to good quality grass and hay.

Also, during periods of limited forage, such as winter months, you may need to supplement with extra feed, such as hay cubes, beet pulp, or alfalfa pellets.


Grain can also be an effective source of weight gain for your horse. However, you must be mindful of the quality and amount of grain you feed your horse.

High-calorie feeds can be harmful if not managed correctly, so work closely with your veterinarian or equine nutritionist to create a feeding plan that works for your horse.

High Calorie Supplements

High-calorie supplements can be a useful addition to your horse’s diet, particularly if they are struggling to gain weight due to a medical issue or dental problem. These supplements may include rice bran, corn oil, linseed, or other high-fiber foods.

However, it’s essential to introduce these supplements gradually and monitor your horse’s reaction to them.

Vitamin Supplements

Vitamin supplements can help your horse maintain a healthy appetite and digestive system, supporting their overall health and metabolism. Vitamin B supplements, for example, can improve your horse’s appetite and help them gain weight.

Frequency of Feeding and Herd Dynamics

The frequency and spacing of meals can also affect your horse’s weight gain, and herd dynamics may play a role. Horses naturally have a hierarchical social structure, so ensure that feed is spread out across a range of feeding stations, and that your horse has access to food without being bullied or intimidated by other horses.

Environmental Changes

Lastly, environmental changes can also impact your horse’s weight gain. For example, providing shelter and blankets can help your horse stay warm and healthy.

Additionally, access to clean fresh water is incredibly important, as dehydration can contribute to weight loss.

Monitoring Thoroughbred Horse Weight Gain

To monitor your horse’s weight gain, you can use a measuring tape to track their girth area, which is a reliable indicator of weight change. Additionally, it’s a good idea to keep a chart or journal, record weight, diet, and progress regularly.

Taking pictures can also be helpful as visual comparisons can help identify any positive changes or concerns. In conclusion, gaining weight in Thoroughbred horses can be a challenge, but it can be done with the right approach.

Be aware of their dental health, consider any parasite infestations, monitor feeding and activity levels, and provide a quality diet of forage and grain. Once you’ve found a feeding routine that works for your horse, take note of progress and fine-tune your approach where necessary.

In conclusion, maintaining a healthy weight for your Thoroughbred horse is crucial for its overall well-being. The key to a healthy weight gain is to take care of your horse’s dental health, manage parasite infestations, control feeding amounts, adjust activity levels, provide quality forage and grain, consider high-calorie supplements and vitamin supplements, monitor feeding frequency and herd dynamics, and pay attention to environmental changes.

By implementing these steps and carefully monitoring your horse’s progress, you can help your Thoroughbred horse gain weight, stay healthy, and perform at its best. FAQs:
