Alfalfa hay can be a nutritious feed for horses, offering high levels of protein, vitamins, and minerals. However, it’s essential to be aware of potential drawbacks, including the risk of digestive upset, nutrient imbalances, and certain health issues like enteroliths. Balancing alfalfa with other forages and considering your horse’s individual needs is key to safely incorporating it into their diet.
What Are the Potential Drawbacks of Feeding Alfalfa Hay to Horses?
While alfalfa hay offers nutritional benefits for horses, several potential drawbacks exist. These include digestive issues due to its rich nature, imbalances in nutrient ratios, and the risk of developing enteroliths. Understanding these factors is crucial for horse owners to make informed decisions about their animal’s diet.
Digestive Upset
Alfalfa is high in protein and calcium, which can cause digestive upset in some horses if introduced too quickly or fed in excessive amounts. The high protein content can lead to increased ammonia production in the hindgut, potentially causing irritation. Additionally, the rich nature of alfalfa can disrupt the balance of the hindgut microbiome, leading to diarrhea or colic in sensitive horses.
Nutrient Imbalances
While alfalfa is rich in certain nutrients, it can also create imbalances if fed as the sole forage source. Alfalfa has a high calcium-to-phosphorus ratio, which can interfere with phosphorus absorption if not properly balanced with other feeds. Over time, this imbalance can lead to skeletal problems, especially in young, growing horses.
Risk of Enteroliths
Enteroliths are mineral concretions that form in the horse’s intestines, and alfalfa consumption has been linked to an increased risk of their development. The high levels of calcium, magnesium, and ammonia in alfalfa can contribute to the formation of these stones, which can cause colic and may require surgical removal. Horses in certain geographic regions, such as California, are more prone to enterolith formation.

How much alfalfa hay is too much for a horse?
The appropriate amount of alfalfa hay depends on the horse’s size, age, activity level, and overall diet. As a general guideline, alfalfa should not make up more than 50% of the horse’s total forage intake. For some horses, even smaller amounts may be more appropriate to avoid digestive upset or nutrient imbalances.
What are the signs of alfalfa hay intolerance in horses?
Signs of alfalfa hay intolerance can include diarrhea, loose stool, mild colic, weight loss, and skin irritation. Some horses may also exhibit behavioral changes, such as increased excitability or nervousness. If you suspect your horse is intolerant to alfalfa, consult with your veterinarian or an equine nutritionist.
Are there any horses that should not eat alfalfa hay?
Horses with certain medical conditions, such as kidney disease or hyperkalemic periodic paralysis (HYPP), may need to avoid or limit alfalfa consumption. Alfalfa’s high protein and potassium content can exacerbate these conditions. Additionally, horses prone to enterolith formation may benefit from a diet lower in alfalfa.
In conclusion, while alfalfa hay can be a valuable addition to a horse’s diet, it’s essential to be aware of the potential drawbacks. Balancing alfalfa with other forages, monitoring your horse’s individual needs, and consulting with equine professionals can help you safely incorporate alfalfa into your horse’s feeding program.
