Bermuda Hay

Bermuda hay is a common forage in warm climates and southern regions, yet many horse owners in areas where it's available don't fully understand its nutritional characteristics or how to feed it effectively. Bermuda grass is heat-tolerant and grows readily in climates where cool-season grasses like timothy struggle, making it invaluable for regions where timothy hay simply won't establish. Understanding what bermuda hay provides nutritionally, how it compares to other hays, and when it's appropriate for different horses helps you make informed feeding decisions if you have access to it.

Bermuda hay is produced from bermuda grass, a warm-season perennial grass that thrives in hot, sunny climates. It's widely grown throughout the southern United States and warm regions globally. For horse owners in these areas, bermuda hay is often the primary locally-available hay option. The nutritional profile depends heavily on the stage at growth when cut and the overall forage quality, making quality assessment critical when selecting bermuda hay.

The practical appeal of bermuda hay is primarily geographic and economic. In regions where it grows readily, bermuda hay is often cheaper and more available than timothy or other cool-season grasses that must be imported. This economic advantage makes it the practical choice for many southern horse operations. Understanding its nutritional characteristics allows effective use rather than defaulting to inferior quality or overfeeding when better options would work.

Bermuda hay quality ranges dramatically from excellent to poor depending on harvest timing, storage, and individual field characteristics. High-quality bermuda cut at the early bloom stage provides decent nutrition for many horses. Poor quality bermuda that's mature when cut, weathered, or inadequately stored provides minimal nutrition. The dramatic quality variation means careful assessment of individual hay is more important with bermuda than with some other hays where more consistent quality is expected.

The regional availability of bermuda creates a different feeding approach for southern horse owners compared to those in northern regions with different hay options. Rather than viewing bermuda as inferior to timothy, understanding how to use bermuda effectively within the constraints and advantages of warm climates allows appropriate feeding decisions. Bermuda can serve horses well when used appropriately and quality is adequate.

Protein content in bermuda hay ranges from 7 to 15 percent depending on maturity at harvest and overall quality. Early-cut bermuda at boot or early bloom stage contains 11 to 14 percent protein, adequate for adult horses at maintenance. Mature bermuda cut at late bloom or later contains only 7 to 9 percent protein, marginal for many horses. This variation makes assessment critical—protein content can vary by several percentage points between fields or even different harvests from the same field. Testing forage when possible removes guesswork about protein content.

Fiber content in bermuda hay tends to be high, particularly as the plant matures. Crude fiber ranges from 30 to 35 percent or higher, which is typical for forage but means bermuda might be higher in fiber than some other hay options. This high fiber supports digestive health but also affects digestibility—more fiber means potentially less digestible energy per pound.

Energy content or digestible energy in bermuda hay varies significantly with quality. Good quality bermuda at early harvest might provide 0.8 to 0.9 megacalories of digestible energy per pound, adequate for horses at maintenance. Poor quality mature bermuda provides perhaps 0.5 to 0.6 megacalories, significantly less energy. This explains why hay quality assessment is so critical—poor quality bermuda might be completely inadequate for anything beyond maintenance needs.

Calcium content in bermuda is typically good, though ratios relative to phosphorus matter. Bermuda generally has adequate calcium for most horses but calcium-to-phosphorus ratios should be checked if feeding as the sole forage, particularly if also feeding grain high in phosphorus. Most quality bermuda maintains reasonable mineral ratios, but individual testing clarifies this.

Vitamin content in bermuda decreases with storage time and light exposure, similar to all hays. Fresh-cut bermuda contains decent levels of vitamin A initially, but after months of storage the vitamin A content drops substantially. Horses fed bermuda exclusively for long periods might benefit from vitamin supplementation, particularly vitamin A.

Trace minerals in bermuda vary with soil mineral content and fertilization practices. Some bermuda grown in mineral-poor soils might be low in copper or zinc. Regional variations and field-specific soil conditions affect mineral content. In areas where trace mineral deficiencies are common, supplementation might be necessary even with bermuda as the forage base.

Digestibility of bermuda varies with maturity and quality. High-quality early-cut bermuda is digested reasonably efficiently. Mature bermuda becomes less digestible, with the horse extracting less nutrition from the same weight. This affects both energy availability and how much hay a horse needs to eat to get adequate nutrition.

Calculate hay quantity for bermuda using the same 2 percent of body weight guideline, though the nutritional density might require adjustment based on quality. A 1,000-pound horse needs approximately 20 pounds of forage daily. This might be 20 pounds of bermuda for a horse at maintenance on good quality hay, or it might need to be higher if the bermuda is poor quality and provides less nutrition per pound.

Quality assessment is critical with bermuda hay. Look for bright green color, indicating hay cut before late maturity. Hay that's dull brown or gray indicates either late harvest or poor storage. Stem thickness matters—finer, more leafy bermuda is better than coarse, stemmy bermuda. Smell for mustiness or mold indicating storage problems. Touch and feel—quality bermuda should be relatively soft with many leaves relative to stems.

Testing bermuda hay through laboratory analysis provides definitive information about protein, minerals, and energy content. While testing costs $35 to $75 per sample, the information guides all your feeding decisions for that hay. Testing is particularly valuable if you're feeding bermuda to young horses, performance horses, or others with higher nutritional requirements where knowing exact nutritional content matters.

Combining bermuda with other forages sometimes improves overall nutrition. Mixing bermuda with legume hay like alfalfa or clover improves protein content. A 50/50 mix of good bermuda with alfalfa provides more balanced nutrition than bermuda alone. This might be practical if alfalfa is available in your area even if bermuda is the main local hay.

Supplementation with grain becomes more important with marginal-quality bermuda. Horses on poor bermuda likely need more grain supplementation than those on high-quality timothy or other premium hays. The reduced energy in poor bermuda might mean a horse needs grain supplementation where they could maintain on forage alone with better hay.

Vitamin mineral supplementation should be considered if bermuda is the sole forage long-term. A basic vitamin mineral supplement designed for grass hay provides insurance against deficiency. This is particularly important for vitamin A after several months of storage.

Water access becomes important because high-fiber hay requires adequate hydration for processing. Ensure water is constantly available for horses on bermuda hay.

Seasonal changes with bermuda affect your feeding program. Fresh-cut bermuda in season might be very different from stored bermuda months later. Monitor your horses and adjust feeding as storage-related nutrient degradation occurs.

Adult horses at maintenance often do fine on good-quality bermuda as their sole forage. These horses have low nutritional demands and can thrive on forage that would be inadequate for other horses. Good bermuda provides adequate nutrition for this group.

Growing young horses need better-quality bermuda than maintenance horses. Poor-quality bermuda is likely inadequate for growth and development without substantial supplementation. Young horses benefit from early-cut bermuda or from mixing bermuda with alfalfa to improve protein and nutrient content.

Performance horses need energy supplementation beyond what bermuda typically provides. Most bermuda simply doesn't have sufficient energy density for horses in work. Supplementation with grain or other concentrates becomes necessary.

Hard keepers struggle with bermuda alone, particularly if quality is marginal. These horses need maximum energy from forage, and poor-quality bermuda doesn't provide it. Hard keepers benefit from good-quality bermuda supplemented with adequate grain, or from better-quality hays if available.

Easy keepers often maintain condition readily on bermuda, particularly good-quality bermuda. They might not need grain supplementation if bermuda quality is adequate. These horses sometimes gain excessive weight on the best-quality bermuda, requiring monitoring.

Lactating mares likely need supplementation with bermuda alone. The protein and energy in bermuda might be marginal for supporting milk production. Better-quality bermuda combined with protein and energy supplementation supports nursing mares more effectively.

Senior horses can eat bermuda if it's soft and leafy enough to manage. Coarse, stemmy bermuda is difficult for older horses to chew. Good-quality early-cut bermuda is often more suitable for seniors than late-cut material.

Poor quality bermuda provides inadequate nutrition for many horses despite being fed at full forage quantities. A horse that looks thin or lacks energy on bermuda alone might be on inadequate hay rather than genuinely being an inefficient feeder.

Vitamin A deficiency can develop over time on stored bermuda, particularly after several months of storage. Symptoms include poor night vision, rough coat, and sometimes increased respiratory infections. Vitamin supplementation prevents this.

Mineral imbalances or deficiencies might occur if bermuda grows in mineral-poor soil. Regional trace mineral deficiencies sometimes require supplementation beyond what bermuda provides.

Colic risk increases with inadequate water intake on high-fiber hay. Ensuring abundant water access reduces this risk.

Mold or quality degradation in storage affects bermuda's nutritional value and safety. Proper storage prevents most quality issues.

Cost savings from inexpensive bermuda can be offset by needing more grain supplementation than you would with better-quality hay. Sometimes the cheaper hay requires more supplementation, reducing actual savings.

Digestive upset occasionally occurs when switching from other hays to bermuda. Introduce gradually to prevent digestive disturbance.

Weather-related quality loss during drying or storage affects bermuda's nutritional value, particularly protein and vitamin content.

Assess bermuda hay quality carefully before purchase. Don't assume all bermuda is the same—quality varies enormously. Insist on seeing hay and evaluating it for color, leaf content, and stem characteristics before committing to purchase.

Test bermuda hay if feeding young horses or those with high nutritional demands. The modest cost of testing provides critical information for making appropriate feeding decisions.

Plan supplementation based on bermuda quality and your horse's needs. Don't feed marginal-quality bermuda expecting the horse to thrive on forage alone.

Monitor your horses on bermuda and adjust supplementation based on condition and performance. Individual horses respond differently to the same hay.

Store bermuda properly under cover to protect it from weather and maintain nutritional quality. Poor storage wastes money on the hay you've already purchased.

Consider mixing bermuda with other forages if available and practical. Improving the overall forage quality through mixing sometimes makes feeding simpler.

Supplement with good vitamin mineral products if bermuda is your sole forage long-term. This insurance prevents deficiency development.

Recognize regional limitations and use bermuda effectively within them rather than wishing for different hay options. Bermuda is the practical choice for many southern regions and works well when used appropriately.
