Bermuda grass hay is a solid, practical choice for most goats. With roughly 10 to 12% crude protein and moderate fiber levels, it covers the nutritional baseline for meat, fiber, and pet goats without the excess protein that some higher-end hays deliver. It’s not the best option for every situation, though. Lactating does and fast-growing kids often need more protein than Bermuda alone provides, and the quality of the hay varies dramatically depending on when it was cut.
Nutritional Profile of Bermuda Hay
Bermuda grass hay typically contains about 10 to 12% crude protein and 55% total digestible nutrients on a dry matter basis. Its fiber content is high: around 74% neutral detergent fiber and 35% acid detergent fiber. That fiber profile makes it a good roughage source that keeps the rumen functioning well, but it also means the hay is less energy-dense than legume hays like alfalfa.
Most meat goats need 10 to 14% crude protein and 60 to 65% total digestible nutrients across their entire diet, including hay, pasture, and any supplements. Bermuda hay sits at the lower end of that protein range and slightly below the energy target. For adult goats at maintenance, those in the off-season between breeding and kidding, or wethers kept as pets, Bermuda hay covers the basics comfortably. You may just need a free-choice loose mineral supplement to round out trace nutrients.
Where Bermuda Falls Short
Lactating does, especially heavy milkers, and young kids in rapid growth phases need protein in the 14 to 16% range or higher. Bermuda hay alone won’t get there. Dairy operations lean heavily on alfalfa for exactly this reason: alfalfa delivers 15 to 20% crude protein along with high calcium levels that support milk production. If you’re running dairy goats on Bermuda hay, expect to supplement with grain, alfalfa pellets, or a protein concentrate to close the gap.
The majority of meat, fiber, and hobby goats don’t need those elevated protein levels. For these animals, feeding alfalfa as the sole hay can actually provide more protein than necessary, which the goat simply excretes as waste. Bermuda is a more economical match for their real requirements.
Harvest Timing Changes Everything
Not all Bermuda hay is created equal, and the single biggest factor is how old the grass was when it was cut. Research on Coastal Bermuda harvested at different intervals shows a clear pattern: grass cut at 3 weeks contained 15.3% crude protein, at 5 weeks it dropped to 11.8%, and at 7 weeks it fell to 10.8%. Crude fiber increased only modestly across those same intervals (28% to 31%), but digestibility declined meaningfully as the plant matured.
This matters when you’re buying hay. Young-cut Bermuda with fine stems and plenty of leaf can rival mid-grade alfalfa in protein content. Mature, stemmy Bermuda that was harvested late is coarser, less digestible, and significantly lower in protein. The same species of grass can range from excellent to marginal goat feed depending on that harvest window. Aim for hay that was cut at 3 to 5 weeks of growth when possible.
Tifton 85 vs. Coastal Bermuda
If you have a choice of Bermuda varieties, Tifton 85 consistently outperforms standard Coastal Bermuda in digestibility. In comparative research, Tifton 85 produced 48% more digestible dry matter and 55% more digestible fiber than Coastal, despite actually having higher total fiber content on paper. The difference comes down to lignin, the woody compound that makes plant cell walls tough to break down. Coastal Bermuda contains more lignin, which limits how much nutrition the goat can actually extract from the hay.
Tifton 85 also yields more per acre, which can make it more available and sometimes more affordable in regions where both varieties are grown. If your local hay supplier offers Tifton 85, it’s the better buy for goats.
How to Pick Good Bermuda Hay
Since you probably can’t run a lab analysis on every bale, visual and tactile cues are your best tools at the feed store or from a hay producer. Here’s what to look for:
- Leaf-to-stem ratio: More leaves relative to stems means more nutrients. Leaves contain significantly more protein and energy than stems. Gently handle the hay and notice whether leaves stay attached or crumble off at a touch. Heavy leaf loss is a sign of rough handling or over-drying.
- Stem size: Fine, small-diameter stems indicate the grass was harvested young. Thick, coarse stems mean it grew too long before cutting and will be harder for goats to digest.
- Color: A consistent green color suggests good curing conditions. Hay that’s turned yellow was likely sun-bleached or rained on after cutting, both of which reduce nutritional value. Dark brown or black patches can indicate the hay was baled too wet, which raises the risk of mold.
- Softness: Soft, pliable hay gets eaten in greater quantities than brittle, crunchy hay. Goats are notoriously picky, and if the hay feels harsh in your hand, they’ll waste more of it by picking through and dropping stems on the ground.
Calcium, Phosphorus, and Urinary Calculi
One concern goat owners sometimes raise with any hay choice is urinary calculi, painful mineral stones that can block the urinary tract in bucks and wethers. The key factor is the calcium-to-phosphorus ratio in the overall diet. A ratio of at least 2 parts calcium to 1 part phosphorus helps prevent stone formation. Bermuda grass hay generally has a moderate calcium-to-phosphorus ratio that falls in a safe range for goats.
Problems typically arise not from the hay itself but from heavy grain feeding. Grain is high in phosphorus and low in calcium, which can flip the ratio in the wrong direction. If you’re supplementing Bermuda hay with grain, provide a free-choice loose mineral formulated with a 2:1 calcium-to-phosphorus ratio to keep things balanced. Alfalfa, by contrast, runs a calcium-to-phosphorus ratio of 3:1 to 5:1, which is higher than ideal but generally not problematic since having more calcium relative to phosphorus is safer than the reverse.
Matching Bermuda Hay to Your Herd
The practical answer is that Bermuda hay works well as a base forage for most goat operations, with some caveats depending on your animals’ life stage. For dry does, bucks outside of breeding season, wethers, and mature goats at maintenance, good-quality Bermuda hay plus a mineral supplement is often all you need. For pregnant does in late gestation, lactating does, and growing kids, plan to supplement with grain, alfalfa hay, or alfalfa pellets to boost protein and energy above what Bermuda provides on its own.
The quality of the specific bale matters more than the species of grass printed on the label. A well-cured, early-cut Bermuda bale with fine stems and bright green color will outperform a late-cut, rain-damaged alfalfa bale every time. Prioritize hay that was harvested young, stored properly, and still has its leaves intact, and Bermuda will serve your goats well.
