Alternative Feeds for Cattle
When Hay Is Too Expensive
📈 Why Hay Prices Keep Spiking
Hay prices are notoriously volatile, driven by drought, transportation costs, fuel prices, and competition from the export market (particularly Japan and South Korea). During the 2022–2024 drought cycles, alfalfa prices in some Western U.S. markets exceeded $400–$500/ton — more than double the 10-year average. Grass hay in the Midwest hit record highs, forcing many cow-calf producers to dramatically reduce herd sizes or seek alternatives.
The good news? Nature and the agri-food industry produce a remarkable variety of alternative feeds. Some are locally abundant, some are nutritionally superior to mediocre hay, and many are significantly cheaper per unit of energy or protein delivered.
🧪 Nutrient Baseline: What Hay Provides
Before exploring alternatives, it helps to know what you're replacing. Below is a general nutrient profile for common hay types, so you can match alternatives accordingly:
| Hay Type | Dry Matter % | Crude Protein % | TDN % | NEm (Mcal/lb) | Avg. Cost ($/ton DM) |
|---|---|---|---|---|---|
| Alfalfa (late bloom) | 89 | 18–20 | 62 | 0.60 | $320–500 |
| Alfalfa-Grass Mix | 88 | 14–17 | 58 | 0.56 | $200–300 |
| Grass Hay (Cool Season) | 89 | 8–12 | 55 | 0.52 | $160–240 |
| Prairie/Native Hay | 90 | 6–9 | 48 | 0.44 | $100–180 |
| Oat/Cereal Hay | 88 | 8–10 | 55 | 0.52 | $120–200 |
TDN = Total Digestible Nutrients; NEm = Net Energy for Maintenance. Prices reflect 2023–2024 U.S. market averages and vary significantly by region.
🌽 1. Silage & Haylage
Silage — fermented, high-moisture forage — is the single most popular and well-proven hay alternative worldwide. Corn silage, sorghum silage, and small-grain silage can each replace roughage needs efficiently, often at 30–50% lower cost per unit of energy delivered.
Corn Silage
Corn silage is a workhorse for beef and dairy cattle alike. Harvested at the milk-to-dough stage (32–38% dry matter), it delivers exceptional energy density and palatability. A typical beef cow requires 40–50 lbs of corn silage per day to meet maintenance needs when supplemented with a modest protein source.
✅ Pros
- High energy — TDN 65–70%
- Economical at $30–60/ton as-fed
- High palatability and intake
- Can be stored 1–2+ years in bunkers
- Reduces sorting behaviour
❌ Cons
- Low in protein (~8% CP) — needs supplement
- High capital cost for harvesting equipment
- Requires bunker, bag, or tower storage
- Spoilage risk if not packed properly
Sorghum & BMR Silage
Brown mid-rib (BMR) sorghum silage is gaining popularity in drier climates where corn struggles. It offers improved digestibility over conventional sorghum due to lower lignin content, and produces 12–16 tons of dry matter per acre under irrigation.
Haylage (Wet Hay)
Haylage — legume or grass forage ensiled at 40–60% moisture — bridges the gap between hay and silage. It preserves nutritional quality better than dry hay in wet climates where field-curing is difficult, and can be baled and wrapped for smaller operations.
🍺 2. Distillers Grains (DDGS)
Dried distillers grains with solubles (DDGS), a co-product of ethanol production from corn, are one of the most nutrient-dense and cost-effective feed supplements available. With crude protein averaging 28–32% and fat at 10–12%, DDGS can replace both energy and protein sources simultaneously.
| Product | Dry Matter % | Crude Protein % | Fat % | TDN % | Typical Cost ($/ton) |
|---|---|---|---|---|---|
| Dried DDGS | 90 | 28–32 | 10–12 | 85 | $150–210 |
| Wet DDGS | 30–35 | 26–30 | 9–11 | 82 | $35–55/ton |
| Modified Wet DDGS | 50–65 | 28–31 | 10–12 | 83 | $55–90/ton |
Feeding recommendations: For beef cows on winter pasture or crop residue, supplementing with 3–5 lbs of DDGS per head per day can replace a significant portion of hay needs while boosting protein intake. Do not exceed 40% of the diet on a dry matter basis due to high sulfur content, which can cause polioencephalomalacia in some situations.
Wet DDGS must be used within 4–7 days of delivery unless frozen, making logistics the key management challenge. For tips on optimizing your entire ration, see our article on Total Mixed Ration (TMR) for Cattle.
🌾 3. Crop Residues & Straw
Corn stalks, wheat straw, soybean stubble, sorghum stubble, and rice straw represent an enormous underutilized feed resource in grain-producing regions. While low in energy and protein individually, they serve as critical roughage sources when supplemented correctly.
Corn Stover Grazing
Turning cattle onto corn stubble fields after harvest is one of the lowest-cost winter feeding strategies available, estimated at $0.20–$0.50/cow/day in stocking-dependent scenarios. Cattle selectively consume the highest-quality portions first — husks, leaves, and grain fragments — before moving to lower-quality stover.
- Stock at 1 cow per 2–3 acres for adequate residue utilization
- Supplement with 1–2 lbs protein/day (DDGS, soybean meal, or cube)
- Limit time to prevent compaction and soil damage in wet conditions
- Monitor body condition score weekly — condition can drop quickly in late stover
- Provide fresh water and mineral supplementation daily
Wheat & Small Grain Straw
Straw typically contains 3–5% crude protein and 40–45% TDN — too low for maintenance of a lactating cow, but adequate as a roughage component in a balanced ration. Ammonia treatment of straw (stacking and injecting anhydrous ammonia) can increase CP to 8–10% and improve digestibility by 10–15 percentage points — a technique worth exploring in straw-abundant areas.
| Residue Type | CP % | TDN % | Cost Range | Best Use | Supplement Needed |
|---|---|---|---|---|---|
| Corn stover (grazed) | 5–8 | 50–58 | $0.20–0.50/cow/day | Cow-calf pairs | Protein supplement |
| Corn stover (baled) | 5–7 | 48–55 | $30–70/ton | All classes | Protein + energy |
| Wheat straw | 3–5 | 40–45 | $40–90/ton | Mature dry cows | Significant supplement |
| Soybean stubble (grazed) | 8–12 | 52–58 | $0.30–0.60/cow/day | Stockers, cows | Minimal in good years |
| Oat/barley straw | 4–6 | 44–50 | $50–100/ton | Dry cows | Protein + energy |
🌱 4. Cover Crops & Stockpiled Forage
Integrating cattle into a cover crop system is one of the most exciting developments in modern beef production — providing cheap grazing, improving soil health, and generating agronomic benefits for the following cash crop. Well-managed cover crop cocktails can provide 30–90 days of fall and early winter grazing at dramatically lower cost than purchasing hay.
Top Cover Crop Mixes for Cattle
Cereal Rye + Hairy Vetch
A classic combo delivering 12–16% CP. Rye provides tonnage and structure; vetch adds legume nitrogen and protein. Excellent for late-fall and early spring grazing.
Turnips + Oats + Radishes
Fast-growing brassicas alongside oats create a high-energy blend. Turnip tops and bulbs deliver 14–18% CP. Cattle relish turnips in cold weather when sugars increase.
Sorghum-Sudan + Cowpeas
Summer-planted mix ideal for stockers. Sorghum-sudan provides high tonnage; cowpeas fix nitrogen and boost protein. Can yield 4–8 tons DM/acre under good conditions.
Stockpiled Fescue
Applying 40–50 lbs N in August and deferring grazing until November creates a standing hay crop. Stockpiled tall fescue can provide 60–90 days of grazing at $0.30–0.60/cow/day.
🪴 5. Whole Cottonseed & Cottonseed Hulls
In the Cotton Belt states (Texas, Oklahoma, Georgia, Mississippi, California), whole cottonseed (WCS) and cottonseed hulls are locally abundant, highly palatable, and nutritionally excellent for mature beef cattle and dry cows.
Whole Cottonseed (WCS)
WCS is a concentrated source of protein (23% CP), energy (TDN 90%+), and effective fibre — making it one of the few single ingredients that can replace both hay and protein supplement in many rations. The intact seed also provides a "bypass" fat source for early lactation cows.
✅ Pros of WCS
- High energy (TDN ~90%) and protein (~23%)
- Effective roughage — maintains rumen function
- Relatively stable pricing in cotton regions
- Easy to self-feed with limit feeders
❌ Cons of WCS
- Gossypol toxicity at high feeding rates
- Not safe for bulls or young calves
- Regional availability limits
- Can spoil in warm/humid storage
🫐 6. Beet Pulp & Sugar By-Products
Sugar beet pulp — the dried residue after sugar extraction — is an outstanding fibre source for cattle, often called a "super fibre" because it ferments rapidly in the rumen and produces significantly more energy than its TDN figure implies. It is palatable, consistent in quality, and widely available in sugar-beet growing regions (Great Plains, Upper Midwest, Pacific Northwest).
| Product | DM% | CP% | TDN% | NDF% | Cost/ton (DM) |
|---|---|---|---|---|---|
| Dried Beet Pulp (plain) | 91 | 9 | 79 | 42 | $170–260 |
| Dried Beet Pulp (w/ molasses) | 91 | 9 | 81 | 40 | $180–270 |
| Wet Beet Pulp | 12–16 | 9 | 78 | 42 | $20–40/ton |
| Molasses (cane/beet) | 75 | 4 | 78 | — | $150–220/ton |
Beet pulp works especially well as a hay extender — replacing 15–30% of hay on a dry matter basis without reducing fibre mat formation in the rumen. It is also useful for improving palatability of lower-quality roughages like straw or cornstalks.
🏭 7. Other Agri-Industrial By-Products
Local availability determines which of these make economic sense, but the table below gives an overview of commonly available by-products that cattle producers can explore through local feed mills, ethanol plants, breweries, and food processors:
| By-Product | Source | CP% | TDN% | Key Notes | Availability |
|---|---|---|---|---|---|
| Soybean hulls | Soy processing | 12 | 76 | High NDF, excellent fibre source; very palatable | Widespread |
| Canola meal | Oil extraction | 36–38 | 70 | Excellent protein source; lower gossypol than cottonseed | Widespread |
| Bakery waste | Food processing | 10–12 | 82 | High energy; variable composition; test before feeding | Regional |
| Brewers grains (wet) | Beer brewing | 25–28 | 62 | Highly perishable (3–5 days); needs immediate use | Regional |
| Citrus pulp (dried) | Juice processing | 7 | 78 | High pectin, fast fermentation; SE/FL availability | Regional |
| Potato waste/culls | Potato packing | 8–9 | 80 | High water; potatoes must be frozen or ensiled | Regional |
| Hominy feed | Corn milling | 10 | 85 | High energy; useful in creep feeds and finishing | Widespread |
| Gin trash | Cotton ginning | 5–8 | 42–48 | Low quality; use only as roughage/fibre source | Cotton Belt only |
💰 Cost Comparison: Hay vs. Alternatives ($/Mcal NEm)
The most meaningful cost comparison is cost per unit of energy delivered (Mcal of Net Energy for Maintenance), not cost per ton — because feeds vary enormously in moisture and nutrient density.
Estimated Cost per Mcal NEm (Dry Matter Basis, 2024 U.S. Avg.)
Note: Costs reflect delivered on-farm averages and will vary significantly by region, season, and supplier. Shorter bars = lower cost per unit of energy = better value.
🔬 Building a Blend Strategy: Practical Ration Examples
No single alternative feed perfectly replaces hay in all situations. The most successful operations combine two or three alternatives to cover energy, protein, and effective fibre simultaneously. Here are three practical ration scenarios for a 1,200 lb beef cow in mid-gestation:
| Scenario | Ration Components | Est. Cost/Head/Day | CP Met? | Energy Met? | Notes |
|---|---|---|---|---|---|
| Corn Belt Grain Region | Corn stover (grazing) + 4 lbs DDGS + mineral | $0.65–0.90 | Yes | Marginal | Excellent low-cost winter program; monitor BCS weekly |
| Feedlot-Adjacent | 20 lbs corn silage + 5 lbs wet DDGS + straw (free choice) | $0.90–1.30 | Yes | Yes | Excellent performance ration; straw controls intake and provides scratch factor |
| Cotton Belt | 5 lbs WCS + cottonseed hulls (free choice) + 2 lbs supplement | $0.80–1.20 | Yes | Yes | Keep WCS to max 5 lbs; excellent fibre from hulls maintains rumen health |
Key Principles for Any Blend
- Always ensure adequate effective fibre (NDF from forage sources): aim for minimum 25–30% forage NDF of diet DM to maintain rumen mat
- Introduce alternative feeds gradually over 7–14 days to allow rumen adaptation
- Never switch cold-turkey from hay to a high-grain or silage diet — acidosis risk is real
- Provide loose mineral free-choice at all times; low-quality roughages are often mineral-deficient
- Weigh and measure feed daily in the transition period; eye-balling can lead to over- or underfeeding
- Work with a nutritionist or extension agent to balance rations formally if using multiple by-products
- Monitor body condition score (BCS) monthly — target BCS 5–6 going into calving
