What to Feed a Horse with Cushing's to Gain Weight: Exploring Nutritional Strategies and Unconventional Ideas

When it comes to managing a horse with Cushing’s disease, weight gain can be a significant challenge. Cushing’s, also known as Pituitary Pars Intermedia Dysfunction (PPID), affects the horse’s metabolism, often leading to weight loss, muscle wasting, and a host of other health issues. Proper nutrition is crucial in helping these horses regain and maintain a healthy weight. However, the approach to feeding a horse with Cushing’s is not always straightforward. This article delves into the best dietary practices for weight gain in horses with Cushing’s, while also exploring some unconventional ideas that might spark further discussion.

Understanding Cushing’s Disease in Horses

Before diving into dietary recommendations, it’s essential to understand how Cushing’s disease affects a horse’s body. Cushing’s is caused by a dysfunction in the pituitary gland, leading to an overproduction of cortisol, a stress hormone. This hormonal imbalance can result in a variety of symptoms, including:

Weight loss and muscle wasting: Despite a good appetite, horses with Cushing’s often struggle to maintain or gain weight.
Laminitis: This painful condition affects the hooves and is a common complication of Cushing’s.
Increased thirst and urination: Horses with Cushing’s often drink and urinate more than usual.
A long, curly coat that doesn’t shed properly: This is one of the most recognizable signs of Cushing’s.

Given these challenges, feeding a horse with Cushing’s requires a careful balance of nutrients to support weight gain without exacerbating other symptoms, particularly laminitis.

Key Nutritional Considerations for Weight Gain

1. High-Quality Forage

Forage should be the foundation of any horse’s diet, and this is especially true for horses with Cushing’s. However, not all forage is created equal. Horses with Cushing’s are often more sensitive to sugars and starches, which can trigger laminitis. Therefore, it’s crucial to choose low-sugar, low-starch forage options.

Grass Hay: Grass hay, such as timothy or orchard grass, is generally lower in sugars and starches compared to legume hays like alfalfa. It provides essential fiber and helps maintain gut health.
Soaked Hay: Soaking hay for 30-60 minutes before feeding can reduce its sugar content, making it safer for horses with Cushing’s.
Haylage: Some horses with Cushing’s may tolerate haylage better than dry hay, as it tends to have lower sugar content. However, it’s essential to monitor the horse’s response, as haylage can sometimes be too rich.

2. Controlled Carbohydrate Intake

Horses with Cushing’s are more prone to insulin resistance, which means their bodies struggle to regulate blood sugar levels. High-carbohydrate feeds can exacerbate this issue, leading to weight loss and laminitis. Therefore, it’s crucial to limit the intake of non-structural carbohydrates (NSCs), which include sugars and starches.

Low-NSC Feeds: Look for feeds specifically formulated for horses with metabolic issues. These feeds are designed to be low in NSCs while still providing essential nutrients.
Avoid Grains: Traditional grains like oats, corn, and barley are high in starch and should be avoided or minimized in the diet of a horse with Cushing’s.

3. Supplemental Fats and Oils

Fats and oils are an excellent source of concentrated calories, making them ideal for horses that need to gain weight. Unlike carbohydrates, fats do not cause a spike in blood sugar levels, making them a safer option for horses with Cushing’s.

Vegetable Oils: Adding vegetable oils, such as corn oil or flaxseed oil, to the horse’s diet can provide a calorie boost without increasing sugar or starch intake.
Rice Bran: Rice bran is another high-fat supplement that can help with weight gain. It’s also rich in vitamin E, which is beneficial for horses with Cushing’s.

4. Protein for Muscle Maintenance

Horses with Cushing’s often experience muscle wasting, so it’s essential to provide adequate protein in their diet to support muscle repair and maintenance.

Alfalfa Pellets: While alfalfa hay may be too rich for some horses with Cushing’s, alfalfa pellets can be a good source of protein without the high sugar content.
Soybean Meal: Soybean meal is another high-quality protein source that can be added to the horse’s diet.

5. Vitamins and Minerals

Horses with Cushing’s may have increased nutritional needs due to their condition. Ensuring they receive adequate vitamins and minerals is crucial for overall health and weight gain.

Vitamin E and Selenium: These antioxidants are particularly important for horses with Cushing’s, as they help combat oxidative stress and support muscle health.
Magnesium: Some studies suggest that magnesium supplementation may help improve insulin sensitivity in horses with Cushing’s.

Unconventional Ideas: Thinking Outside the Feed Bucket

While the above strategies are well-established, there are some unconventional ideas that might be worth considering when trying to help a horse with Cushing’s gain weight. These ideas are not necessarily backed by scientific research but could spark further discussion and exploration.

1. Herbal Supplements

Some horse owners and practitioners advocate for the use of herbal supplements to support horses with Cushing’s. Herbs like milk thistle, dandelion, and burdock root are believed to support liver function and overall health. While there is limited scientific evidence to support these claims, some owners report positive results.

2. Probiotics and Prebiotics

Gut health is crucial for overall well-being and nutrient absorption. Some horse owners have found that adding probiotics or prebiotics to their horse’s diet can improve digestion and help with weight gain. Again, more research is needed in this area, but it’s an interesting avenue to explore.

3. Acupuncture and Chiropractic Care

While not directly related to nutrition, some holistic practitioners suggest that acupuncture or chiropractic care can help improve a horse’s overall health and metabolism, potentially aiding in weight gain. These therapies are often used in conjunction with dietary changes.

4. Environmental Enrichment

Stress can negatively impact a horse’s ability to gain weight. Providing a low-stress environment with plenty of turnout, social interaction, and mental stimulation can help improve a horse’s overall well-being and potentially support weight gain.

Conclusion

Feeding a horse with Cushing’s to gain weight requires a thoughtful and tailored approach. By focusing on high-quality forage, controlled carbohydrate intake, supplemental fats, and adequate protein, you can help your horse regain and maintain a healthy weight. Additionally, considering unconventional ideas like herbal supplements, probiotics, and holistic therapies may offer additional support. Always consult with your veterinarian or an equine nutritionist to develop a diet plan that meets your horse’s specific needs.

Q: Can I feed my horse with Cushing’s beet pulp? A: Yes, beet pulp is a good option for horses with Cushing’s as it is low in sugar and starch and provides a good source of fiber and calories. However, it should be soaked before feeding to prevent choking.

Q: How much fat should I add to my horse’s diet? A: The amount of fat to add depends on the individual horse’s needs. Start with small amounts (e.g., 1/4 cup of oil per day) and gradually increase, monitoring the horse’s weight and overall health.

Q: Are there any specific feeds to avoid for horses with Cushing’s? A: Yes, avoid feeds high in non-structural carbohydrates (NSCs), such as grains (oats, corn, barley) and molasses-based feeds. These can exacerbate insulin resistance and increase the risk of laminitis.

Q: Can I give my horse with Cushing’s treats? A: Treats should be given sparingly and should be low in sugar and starch. Carrots and apples in small amounts are generally safe, but avoid sugary treats like mints or commercial horse treats.

Q: How often should I feed my horse with Cushing’s? A: Horses with Cushing’s benefit from frequent, small meals rather than large meals. This helps maintain stable blood sugar levels and supports better digestion. Aim for 3-4 meals per day if possible.
