Section 1 Overview
If you're looking for good quality hay and orchard grass is available in your area, it's an excellent choice. Orchard grass is one of the better grass hay options for horses, palatable and nutritious and reasonably forgiving to grow and store. It's not timothy hay, which is the gold standard in many regions, but in areas where timothy doesn't grow well, orchard grass is the right answer. Many horses prefer orchard grass to timothy because it's softer and more palatable. If your horse has a choice between orchard grass and timothy, some horses will actually choose orchard grass, which tells you they like it.
The advantages of orchard grass over timothy include better palatability, softer texture, and adequate nutrition for most horses. Orchard grass is a softer grass than timothy, which some horses genuinely prefer. It's also slightly higher in protein than timothy, though both are adequate. Orchard grass grows well in many regions where timothy struggles, especially in areas with warmer summers. In some parts of the country, orchard grass is more available and cheaper than timothy because it grows so readily. Additionally, orchard grass is often more digestible than timothy, which benefits horses with sensitive systems or those needing maximum nutrition from forage.
The minor disadvantages of orchard grass versus timothy include slightly less established reputation among traditional horse people and slightly different nutrient profile. Some horsemen swear by timothy and view orchard grass as second-rate, which isn't really fair. The reality is both are excellent hay. Orchard grass is also a bit higher in some minerals and lower in others than timothy, which might matter depending on your supplement situation. But these are very minor considerations. For most horses in most situations, orchard grass is excellent forage.
Quality orchard grass hay looks bright green, smells fresh and pleasant, and has soft, fine stems with minimal seed heads. Poor quality orchard grass is brown, dusty, has coarse stems, or shows signs of weather damage. The difference between good orchard grass and poor orchard grass is huge. Good quality orchard grass is fantastic. Poor quality orchard grass is just storage. Sourcing good quality is the key to using orchard grass successfully.
Understanding the nutritional characteristics of orchard grass helps you manage your overall feeding program effectively. Orchard grass is lower in calcium than alfalfa, higher in calcium than timothy. It's moderate in protein, higher in fiber than legumes, and provides good digestible energy. These characteristics make it suitable for most horses without the need for aggressive supplementation if quality is good. Where you need to pay attention is making sure you have adequate calcium, which might come from orchard grass, might come from supplements, or might come from a combination.
Many horses thrive on orchard grass as their primary hay with reasonable supplementation. It's not a miracle hay that eliminates the need for minerals and other attention. But it's a solid, reliable forage that works well for pleasure horses, performance horses, and most other categories. If orchard grass grows well in your area and you can source good quality, it's a simple answer to the hay question.
Section 2 Nutritional Details
The nutrient profile of orchard grass varies depending on stage of growth when cut, weather conditions, and storage. Early-cut orchard grass, harvested when the plant is in boot stage or early bloom, is higher in protein and digestible energy than late-cut hay. Late-cut orchard grass, harvested in full bloom or later, is lower in protein but higher in fiber. Most commercial orchard grass hay is cut somewhere in mid-bloom, which provides a decent balance of protein and fiber and digestible energy.
Typical early-cut orchard grass hay has about twelve to fourteen percent crude protein, which is adequate for adult horses and many growing horses. Late-cut orchard grass might have eight to ten percent protein. This is still perfectly adequate for adult maintenance, but if you have hard keepers or young growing animals, the timing of cut matters. The digestible energy in orchard grass is typically around one point nine to two point one megacalories per kilogram depending on stage of growth, which is adequate for most horses.
Calcium content of orchard grass hay is typically around four tenths of a percent, which is reasonable but not high. Phosphorus is typically around two tenths of a percent. This gives a calcium-to-phosphorus ratio of roughly two-to-one, which is appropriate for horses. This is very different from timothy, which sometimes has an inverted ratio depending on where it's grown. For this reason, orchard grass is actually easier to balance nutritionally in some regions. Magnesium in orchard grass is typically around one and a half tenths of a percent, which is adequate. Potassium is typically around two percent, which is adequate.
Trace minerals in orchard grass vary widely depending on soil mineral content. If selenium is low in your region's soil, orchard grass hay will be low in selenium. If copper is deficient in local soils, hay will be deficient. This is one place where regional variation really matters. Some areas with rich soils produce hay adequate in trace minerals. Other regions require supplementation regardless of what hay you feed. Testing your hay or knowing your region's mineral profile helps you plan supplementation.
Vitamin A content of orchard grass is good when freshly cut and dried, approximately forty to fifty thousand IU per pound. This is adequate for most horses eating good quality hay daily. However, vitamin A degrades over time and with exposure to light and heat. Hay that's been stored for a year or more, especially if stored in poor conditions, will have significantly lower vitamin A. If you're feeding old hay, vitamin A supplementation makes sense.
Vitamin D in orchard grass hay is typically adequate when hay is sun-cured properly. Horses getting sunlight have vitamin D synthesis from skin exposure, so hay vitamin D is less critical than vitamin A. The other vitamins in hay are variable and often marginal. B vitamins are present but might be depleted in old hay. E vitamins are present but supplemental vitamin E is often beneficial.
The digestibility of orchard grass is high, typically around sixty percent of the dry matter being digestible. This means horses extract good nutrition from orchard grass compared to some other forage sources. The combination of decent nutrient content and high digestibility makes orchard grass an efficient forage choice.
Section 3 Feeding Guidelines
Feed quality orchard grass hay free-choice or in quantities matching your horse's needs. Most horses eat one point five to two percent of their body weight daily in forage. For a thousand-pound horse, that's fifteen to twenty pounds of hay daily. Quality orchard grass provides adequate nutrition at these levels for adult horses in light to moderate work. If feeding quantity orchard grass for a horse at maintenance plus light work, you might do just the basic mineral supplementation and nothing else.
Choose orchard grass that's been properly dried and stored to preserve quality. Hay that's been rained on loses nutrient content. Hay stored in direct sun bleaches and loses quality. Hay stored in damp conditions develops mold. The best orchard grass is stored indoors, protected from weather. If buying hay, ask the seller about storage conditions. Hay stored well is worth a modest premium.
When transitioning to a new orchard grass hay from different storage or location, you generally don't need the slow, gradual transition you'd use for grains. Horses handle hay transitions fine if the forage type is the same. You can switch from timothy to orchard grass more gradually if transitioning between very different forage types, but if both are orchard grass, horses adjust fine.
Mixing orchard grass with other hay types is common and often beneficial. Mixing orchard grass with alfalfa adds protein, calcium, and creates a more balanced diet for growing animals or performance horses. The ratio depends on what you're trying to achieve. Mixing timothy and orchard grass creates variety and might better suit regional hay availability. Orchard grass mixed with clover or other legumes improves protein and minerals.
Storage of orchard grass hay should be cool, dry, and protected from weather and pests. Bales stacked in direct sun bleach and lose quality. Bales stored outdoors without cover lose nutrient content to rain and weather. The best storage is a covered structure where hay stays dry but air can circulate to prevent mold. If you have limited storage, at least keep hay protected with a tarp from rain.
Quantity to maintain depends on your horse and your activity. Most horses eating quality orchard grass plus reasonable mineral supplementation maintain good weight and health. Hard keepers might need supplemental grain. Easy keepers might need less hay or limited access. The only way to know is to feed, observe, and adjust.
Section 4 Horse Type Considerations
Easy keeper horses do well on quality orchard grass hay with limited additional supplementation. Many easy keepers thrive on orchard grass hay plus a basic mineral mix and nothing else. The soft, palatable nature of orchard grass means easy keepers actually eat efficiently, which is fine. Some easy keepers might need restricted hay access during peak grazing season when lush pasture is available, but orchard grass hay alone usually doesn't cause weight gain problems.
Hard keeper horses benefit from orchard grass hay because of its digestibility and palatability. Hard keepers sometimes eat more readily when offered palatable hay compared to coarser options. The higher digestibility means hard keepers get more nutrition from what they eat. Hard keepers usually need orchard grass hay plus supplemental grain to maintain weight, but the hay portion can be quite significant in their diet.
Performance horses do well on orchard grass hay as their forage base. The digestibility and nutrient content support work capacity. Performance horses paired with quality grain usually maintain excellent condition on orchard grass hay. Some trainers prefer orchard grass for performance horses because it's digestible and doesn't have the reputation of being heating that some less conventional forages have.
Senior horses often do well on quality orchard grass hay because of the soft, fine stems that are easier on aging teeth and digestive systems. Older horses sometimes have dental wear that makes coarser hay difficult. Orchard grass, especially if harvested at the right stage, has a softer texture than timothy or other grasses. This makes orchard grass a reasonable choice for seniors with some dental challenges.
Growing foals do well on orchard grass hay that's been analyzed for nutrient content because you can supplement specific deficiencies if needed. Quality orchard grass plus appropriate grain and minerals supports growth adequately. The key with foals is ensuring nutrition is complete, and you can accomplish that with quality orchard grass if you manage supplementation.
Section 5 Potential Issues
Poor quality orchard grass hay is common and disappointing. Hay that's been rained on, stored poorly, or harvested late is brown, dusty, unpalatable, and low in nutrients. Some horses refuse poor quality orchard grass outright. Don't assume orchard grass is automatically good hay. Quality matters enormously. Pay attention to color, smell, and texture when buying.
Mold in orchard grass can develop if hay is stored damp or in poor conditions. Moldy hay is dangerous and can cause serious health issues. Never feed hay that smells musty, looks discolored, or shows visible mold. If you have stored hay that got wet, check carefully for mold before feeding. Some molds produce toxins that cause serious illness.
Mineral deficiencies can develop if orchard grass hay grown in deficient soil is fed without supplementation. Low-selenium areas produce hay deficient in selenium, which can cause muscle problems. Low-copper regions have hay deficient in copper, which affects coat and hoof quality. You can't fix this just by choosing orchard grass. You have to know your region and supplement accordingly. This is why hay analysis is valuable. It tells you what you're actually getting and what you need to supplement.
Digestive upset from poor quality hay sometimes happens. If hay is old, dusty, or moldy, some horses develop loose stool or colic. This is a sign that hay quality is the problem, not that orchard grass is bad. Switch to good quality hay and observe improvement.
Palability issues are rare with orchard grass compared to some hays, but some batches are less palatable than others. If your horse seems uninterested in their orchard grass hay, poor quality or exposure to something unpleasant might be the issue. Fresh, good quality orchard grass is almost universally appealing.
Section 6 Practical Tips
Buy the best quality orchard grass you can find and afford. The difference between premium and budget hay is huge in terms of quality and results. Premium hay might cost a bit more per bale, but your horse gets better nutrition, better health, and often eats more efficiently, potentially using less hay overall. It's worth the investment.
If possible, source hay locally from farmers you can visit. You can see how it's grown, stored, and maintained. You can feel the hay, smell it, and evaluate quality directly. Local sourcing usually provides better quality than buying from large dealers or shipping from distant regions.
Common mistakes include buying hay in bulk without understanding what you're getting. Buy a few bales first, evaluate them, then buy in quantity if satisfied. Another mistake is storing hay poorly and letting quality degrade. If you're investing in good hay, store it properly. Another mistake is assuming all orchard grass is equal. It's not. Source matters, growing conditions matter, harvest timing matters. Good orchard grass is excellent. Poor orchard grass is just storage.
If your horse thrives on orchard grass hay, stick with the same supplier and same hay as much as possible. Consistency is valuable in horse feeding. If you have to switch hay sources, do it gradually by mixing the old and new hay for a week or so, even though forage transitions are generally less critical than grain transitions.
Have your hay analyzed if you want to know exactly what you're feeding. Hay analysis is inexpensive and gives you actual numbers for minerals, vitamins, and nutrients rather than estimates. This is especially valuable if you're feeding a special needs horse or trying to optimize nutrition. Most county extension offices can tell you where to send hay for analysis.
