The safe amount of alfalfa cubes for horses changes based on the horse’s size, age, workload, and overall diet. Generally, alfalfa cubes should make up no more than 50% of the horse’s total hay portion, or about 0.5% to 1.5% of the horse’s body weight in dry matter daily.
The Importance of Alfalfa in a Horse’s Diet
Alfalfa, often called lucerne, is a popular feed for horses. It offers high protein and calcium. Many horse owners use alfalfa cubes because they are easy to store and feed. They are just compressed alfalfa hay. But feeding too much can cause problems. Knowing the right amount is key to keeping your horse healthy.
Alfalfa Cube Nutritional Value for Horses
Alfalfa cubes are not just filler; they pack a punch nutritionally. They differ quite a bit from grass hay.
| Nutrient | Typical Range in Alfalfa Cubes | Importance |
|---|---|---|
| Crude Protein | 17% – 22% | Supports muscle growth and repair. |
| Calcium | High (Often 1.5% or more) | Good for bone health. |
| Energy (TDN) | Moderate to High | Provides fuel for work. |
| Fiber | High | Keeps the gut healthy. |
Because alfalfa is high in protein and calcium, you must balance it with other feeds. Too much calcium can affect how the horse uses other minerals, like phosphorus. A horse that is not working hard needs less protein than a growing foal or a hard-working athlete.
Calculating Your Horse’s Total Daily Intake
Before deciding on alfalfa cubes, you must know how much hay should a horse eat overall. A horse should eat between 1.5% and 3% of its body weight in total dry matter feed daily. Most of this should come from forage (hay or pasture).
Let’s look at a 1,000-pound horse.
- Low end (Maintenance): 1,000 lbs * 1.5% = 15 lbs of dry feed per day.
- High end (Hard Work): 1,000 lbs * 3.0% = 30 lbs of dry feed per day.
This total intake includes all hay, pasture, and concentrates. Alfalfa cubes fit into the hay portion of this total.
Determining Alfalfa Cube Amount for Horse Needs
Alfalfa cubes are very dense. One pound of cubes is much more feed than one pound of loose hay. This is because the water has been removed. Always weigh your cubes to be accurate.
Alfalfa cube feeding guidelines suggest they should not be the only source of forage. They lack the long-strand fiber horses need for constant chewing and gut motility.
We must figure out how much of the total hay requirement can be alfalfa cubes.
- For most adult horses in light to moderate work, alfalfa cubes should be less than 50% of their total hay intake.
- For horses needing extra calories or protein (like pregnant mares or hard keepers), this percentage might go up slightly, but professional guidance is best.
Creating a Horse Ration with Alfalfa Cubes
Feeding correctly means balancing calories, protein, and minerals. Here is a step-by-step guide for determining alfalfa cube amount for horse diets.
Step 1: Determine Total Daily Dry Matter Intake
Use the horse’s weight to find the total food needed daily.
Example Horse: 1,200-pound mare in light work.
- Target intake: 2.0% of body weight.
- 1,200 lbs * 0.02 = 24 pounds of total dry feed per day.
Step 2: Establish the Forage Base (Grass Hay)
Start with grass hay, like Timothy or Orchard grass. This provides the necessary long-strand fiber. Grass hay should usually be the main bulk of the diet.
Let’s say we want grass hay to be 60% of the total diet for fiber and bulk.
- 24 pounds total feed * 0.60 = 14.4 pounds of grass hay daily.
Step 3: Calculate the Alfalfa Cube Portion
The remaining portion of the diet can come from alfalfa cubes, concentrates, or pasture. If we decide the cubes will make up the other 40% of the forage portion, we calculate that amount.
- 24 pounds total feed * 0.40 = 9.6 pounds of supplementary feed (cubes + grain).
If the horse gets no grain, then 9.6 pounds of cubes would be the maximum. However, this is likely too high for a horse in light work. Let’s use a more practical limit.
A safe amount of alfalfa cubes for horses in light work is usually around 4 to 6 pounds (dry weight) per day, mixed with grass hay.
If we aim for 5 pounds of cubes:
- 5 lbs of alfalfa cubes + 14.4 lbs of grass hay = 19.4 pounds of forage.
- This 19.4 pounds is about 1.6% of the horse’s body weight, which is a good base.
The remaining weight (24 lbs total – 19.4 lbs forage = 4.6 lbs) would be made up of minerals, salt, and any required grain ration based on the horse’s energy needs.
Step 4: Consult an Alfalfa Cube Feeding Chart for Horses
While general rules exist, every horse is different. A simple alfalfa cube feeding chart for horses might look like this for a 1,000 lb horse, depending on its role:
| Horse Activity Level | Total Daily Feed (Dry Weight) | Target Alfalfa Cubes (Dry Weight) | Notes |
|---|---|---|---|
| Very Light/Senior | 15 – 18 lbs | 1 – 3 lbs | Use for supplementation only. |
| Light Work/Breeding | 18 – 22 lbs | 3 – 6 lbs | Good protein boost. |
| Moderate Work | 22 – 26 lbs | 5 – 8 lbs | Needs careful monitoring of condition. |
| Hard Work/Lactation | 26+ lbs | 8 – 12 lbs | Often requires added grain or fat sources. |
Note: These are starting points. Always monitor body condition.
Specialized Feeding Scenarios
The ideal daily alfalfa cube intake horse depends heavily on the horse’s specific requirements.
Feeding Working Horses
Horses in heavy training need energy and protein for muscle repair. Alfalfa cubes provide excellent quality protein and good energy density. For these horses, the percentage of alfalfa in the total ration can safely increase, but you must watch their condition closely. If they get too much protein, it is wasted as heat and can strain the kidneys.
Feeding Seniors and Horses Losing Weight
Alfalfa cubes are excellent for older horses or those struggling to maintain weight. They are often easier to chew than tough hay. The high digestibility means they get more nutrition from less volume.
However, seniors must still have enough long-stem forage to keep their gut moving well.
Feeding Growing Horses and Mares
Foals, yearlings, and lactating mares have high demands for calcium and protein for growth and milk production. Alfalfa cubes are beneficial here. However, excessive calcium can interfere with phosphorus absorption, leading to skeletal issues in growing horses. Therefore, you must maintain a proper calcium-to-phosphorus ratio (ideally 1.5:1 or 2:1) in the total diet.
Practical Considerations for Alfalfa Cube Feeding Frequency Horse
How often you feed matters for digestive health. Horses are trickle feeders. Their stomachs are small and designed for constant grazing.
The total daily ration should be split into at least two, but preferably three or four, small meals.
If you feed 5 pounds of cubes per day:
- Twice a day: 2.5 pounds per feeding.
- Three times a day: About 1.7 pounds per feeding.
It is better to feed smaller amounts more often. This helps prevent overloading the digestive system with dense, high-protein feed all at once.
Soaking Alfalfa Cubes: A Crucial Step
Alfalfa cubes, when fed dry, can be a serious choking hazard. They expand rapidly when they absorb water in the esophagus. This is a major safety concern.
Always soak alfalfa cubes before feeding.
How to Soak:
- Use at least twice the volume of warm water to cubes. (e.g., 1 pound of cubes needs 2 pounds of water).
- Allow them to soak for 15 to 30 minutes until they break down into a soft mash.
- They should be easily mashable between your fingers.
- Never feed dry cubes unless your veterinarian advises otherwise for a specific medical reason, and even then, extreme caution is needed.
Transitioning Horse to Alfalfa Cubes Safely
You cannot switch a horse’s diet overnight. Digestive upset, like colic, can result from sudden changes. Transitioning horse to alfalfa cubes requires patience.
Follow a slow introduction schedule, usually over 7 to 14 days. This allows the hindgut microbes time to adjust to the different nutrient profile.
Sample Transition Plan (For a horse adding 4 lbs of cubes daily):
| Day | Old Feed (Grass Hay/Feed) | New Feed (Alfalfa Cubes – Soaked) | Percentage of New Feed |
|---|---|---|---|
| 1-2 | 100% | 10% (0.4 lbs) | 10% |
| 3-4 | 90% | 20% (0.8 lbs) | 20% |
| 5-6 | 80% | 30% (1.2 lbs) | 30% |
| 7-8 | 70% | 40% (1.6 lbs) | 40% |
| 9-10 | 60% | 50% (2.0 lbs) | 50% |
| 11-12 | 50% | 60% (2.4 lbs) | 60% |
| 13-14 | 40% | 70% (2.8 lbs) | 70% |
| After Day 14 | Adjust based on need | Target Amount (4 lbs) | 100% of target |
Monitor your horse’s manure consistency and body condition daily during this transition period. If manure becomes soft or runny, slow down the introduction rate.
Risks Associated with Overfeeding Alfalfa Cubes
While alfalfa is nutritious, excess consumption poses specific health risks.
1. Colic Risk
Feeding large volumes of dense, soaked cubes can cause digestive issues if not managed properly. The sudden intake of highly fermentable material, or feeding cubes that haven’t fully soaked, can lead to impaction or gas colic. Ensure the horse is also receiving adequate water intake.
2. High Protein Load
If your horse is not exercising heavily, feeding too many cubes leads to excess protein. The horse must process this extra nitrogen, which stresses the kidneys and excretes energy as heat. This often results in the horse becoming too “hot” or excitable.
3. Calcium and Phosphorus Imbalance
This is a critical concern, especially for growing animals. Alfalfa has a high calcium level (often 2:1 Ca:P ratio, while grass hay is often 1:1 or lower). If you feed a very high percentage of alfalfa cubes along with a grain mix that is already high in phosphorus, the overall ratio can become too skewed, hindering proper bone development.
4. Obesity and “Alfalfa Belly”
Alfalfa cubes are calorie-dense. Feeding too many, even to a horse in light work, will likely lead to weight gain. This is crucial for ponies or easy keepers who must be restricted severely. For some horses, relying too heavily on cubes instead of long-stem hay can lead to a condition sometimes called “hay belly,” where the horse looks fat but lacks proper muscle tone due to insufficient long-strand fiber.
Comparing Cubes to Pellets and Loose Hay
People often wonder if alfalfa pellets are better than cubes, or if loose hay is sufficient.
Alfalfa Cubes vs. Pellets
Both are simply compressed alfalfa.
- Cubes: Larger diameter. Generally require more chewing time than pellets, which can be slightly beneficial for slowing intake. Still must be soaked.
- Pellets: Smaller. They soak much faster but can be eaten very quickly if not restricted, increasing choke risk.
Cubes vs. Loose Hay
Loose hay is the gold standard for equine digestion because it requires long chewing times, stimulating saliva production (a natural buffer against stomach acid) and promoting gut motility.
Alfalfa cubes are best used:
- As a supplement to boost protein or calories in an existing grass hay diet.
- As a way to ensure intake for horses with dental issues who struggle to chew long hay strands.
- When storage space for loose hay is limited.
You must always try to replace at least some of the cubes with long-stem hay if possible.
Comprehending Feed Labels and Weight Conversions
One common source of error in daily alfalfa cube intake horse calculations is confusing volume with weight.
A scoop that holds 5 pounds of grain might only hold 3 pounds of cubes because cubes are less dense than grain. Always use a reliable scale.
Conversion Note: The weight of soaked cubes is much higher than dry cubes because of the added water. Never weigh the soaked product to calculate the dry matter intake; only weigh the dry cubes before soaking.
If you are managing a complex feeding program or have a performance horse, it is wise to work with an equine nutritionist. They can create a precise horse ration with alfalfa cubes using laboratory analysis of your specific feedstuffs.
Frequently Asked Questions (FAQ)
Can I feed my horse alfalfa cubes free-choice?
No. Because of their high nutrient density and the risk of choking when dry, alfalfa cubes should never be fed free-choice. They must be measured precisely and usually soaked before being served in meals.
Are alfalfa cubes bad for a horse’s kidneys?
Excessive protein intake over a long period can strain the kidneys as they process the resulting nitrogen waste. Alfalfa cubes are not inherently bad for the kidneys, but feeding far more than the horse needs for its workload and body maintenance will cause problems. Stick to recommended guidelines.
How much water does a horse need when eating cubes?
A horse needs plenty of water overall, but specifically when feeding cubes, water intake is critical. Since you soak the cubes, they get some moisture upfront. However, ensure access to fresh, clean water at all times. If a horse eats dry cubes (which should be avoided), they need extra water to help push the feed through.
What is the best way to feed alfalfa cubes to prevent choking?
The absolute best practice is to soak the cubes completely until they turn into a mash. If soaking is impossible due to travel or immediate need, use very small amounts mixed thoroughly into a larger volume of wet grain or hay pellets, but this should be a rare exception, not the rule.
Can alfalfa cubes cause ulcers in horses?
Alfalfa has a naturally high buffering capacity due to its high calcium content, which can actually help neutralize stomach acid. However, feeding any dense concentrate, including cubes, in large meals without sufficient long-stem hay beforehand can still contribute to ulcer development by leaving the stomach empty between feedings. Ensure consistent access to grass hay around meal times.
