Understanding Seasonal Cattle Nutrition
Nature designed cattle to thrive on seasonal forage variations, but modern cattle production demands we understand and optimize their nutrition throughout the year. Unlike monogastric animals that require consistent diets, cattle possess a remarkable four-compartment digestive system that adapts to seasonal feed changes, yet each season presents unique nutritional opportunities and challenges that directly impact cattle health, productivity, and profitability.
Seasonal feeding isn't just about what's available—it's about strategic nutrition management that aligns with natural forage cycles, animal physiological needs, and economic realities. A well-planned seasonal feeding program can reduce feed costs by 20-40% while improving animal performance compared to static year-round feeding approaches.

Spring Diet: Abundance and Management
🌱 Spring Feeding Overview
Spring represents the most dramatic dietary change of the year. As temperatures warm and daylight increases, dormant pastures explode with growth, offering cattle their most nutritious forage of the year. However, this abundance comes with management challenges that can impact cattle health if not properly addressed.
Characteristics of Spring Forage
Spring pasture differs significantly from other seasonal forages:
| Forage Characteristic | Spring Value | Management Implications |
|---|---|---|
| Moisture Content | 75-85% | High intake volume, low dry matter per bite |
| Crude Protein | 20-28% | Exceeds needs, may cause loose manure |
| Energy (TDN) | 65-75% | Excellent energy supply |
| Fiber (NDF) | 40-50% | Lower than ideal, rapid passage rate |
| Magnesium | Often low | Grass tetany risk increases |
| Digestibility | 75-85% | Highly digestible, excellent gains |
Spring Nutritional Challenges
Despite spring's nutritional bounty, several challenges require active management:
Grass Tetany (Hypomagnesemia)
Spring's rapid grass growth often contains insufficient magnesium, particularly during cool, cloudy conditions. Grass tetany affects lactating cows most severely and can be fatal within hours if untreated. Prevention strategies:
- Provide high-magnesium mineral supplements (12-14% magnesium)
- Offer free-choice hay to increase fiber intake
- Avoid turning hungry cattle onto lush pasture
- Monitor high-risk cows (older, high producers) closely
- Consider magnesium oxide boluses or dusting pastures with magnesium fertilizer
Bloat Management
Legume-rich spring pastures (particularly alfalfa and clover) can cause frothy bloat, a potentially fatal condition where gas cannot escape the rumen. Prevention approaches:
- Never turn hungry cattle onto legume pastures
- Fill cattle with dry hay before spring turnout
- Use bloat prevention products (poloxalene-based)
- Maintain grass-legume mix rather than pure legume stands
- Graze when forage is dry, not wet with dew or rain
Optimal Spring Feeding Strategy
A successful spring feeding program balances pasture utilization with health management:
- Gradual transition: Allow 7-14 days for rumen adaptation when moving from winter feeds to spring pasture
- Limit initial grazing: Start with 2-3 hours daily, gradually increasing to full-time grazing
- Maintain hay access: Keep long-stem hay available for the first 2-3 weeks to provide fiber
- Mineral supplementation: Provide free-choice minerals emphasizing magnesium
- Rotational grazing: Implement short rotation periods to harvest grass at optimal quality (6-10 inches)
- Body condition monitoring: Spring is ideal for gaining condition; target BCS 5-6
Spring Supplementation Needs
| Cattle Class | Typical Supplement | Amount/Day | Purpose |
|---|---|---|---|
| Dry cows | Minerals only | 2-4 oz | Prevent deficiencies |
| Lactating beef cows | High-Mg minerals | 3-4 oz | Tetany prevention |
| Growing calves | Minerals | 2-3 oz | Support rapid growth |
| Dairy cows | Concentrate mix | 10-20 lbs | Meet milk production needs |
| Bulls | Minerals | 3-4 oz | Breeding season condition |
Summer Diet: Heat Stress and Forage Quality
☀️ Summer Feeding Overview
Summer brings contrasting challenges: heat stress reduces appetite while forage matures and declines in quality. As grasses produce seed heads and stems lignify, nutritional value drops even as cattle's environmental stress increases. Successful summer management requires balancing these competing factors.
Summer Forage Characteristics
As summer progresses, forage undergoes significant changes:
Early Summer (June-July)
- Protein: 12-18%
- TDN: 55-65%
- Still vegetative growth
- Good digestibility
- Adequate nutrition for most cattle
Late Summer (August-September)
- Protein: 8-12%
- TDN: 45-55%
- Mature, stemmy growth
- Reduced digestibility
- Supplementation often needed
Heat Stress Impact on Nutrition
Heat stress profoundly affects cattle feeding behavior and nutritional needs:
| Temperature Range | Feed Intake Change | Behavioral Adaptation | Management Response |
|---|---|---|---|
| Below 77°F | Normal | Normal grazing patterns | Standard feeding practices |
| 77-85°F | -5 to -10% | Seek shade midday | Ensure adequate water, provide shade |
| 85-95°F | -10 to -20% | Graze morning/evening only | Increase energy density of feeds |
| Above 95°F | -20 to -35% | Minimal activity, heavy panting | Emergency cooling, electrolytes |
Summer Feeding Strategies
Optimize summer nutrition with these evidence-based approaches:
- Rotational grazing: Move cattle to fresh paddocks in early morning to capture regrowth with higher nutritional quality
- Stockpiling: Set aside 20-30% of pasture in late summer for fall grazing, allowing rest and regrowth
- Supplemental protein: Add protein when forage crude protein drops below 10% (late summer)
- Energy supplementation: Consider grain or energy blocks when forage TDN falls below 55%
- Water management: Ensure clean, cool water access; cattle need 12-20 gallons daily in summer heat
- Shade provision: Provide natural or artificial shade (40-50 sq ft per cow)
- Mineral focus: Emphasize salt and trace minerals as water intake increases
Summer Supplementation Guidelines
| Forage Quality | Supplement Type | Amount (lbs/day) | Expected Response |
|---|---|---|---|
| High (early summer) | Minerals only | 0.15-0.25 | Prevent deficiencies |
| Medium (mid-summer) | Protein supplement | 1-3 | Maintain body condition |
| Low (late summer) | Protein + energy | 3-6 | Prevent weight loss |
| Drought conditions | Complete supplement or hay | 10-15+ | Replace inadequate forage |
Drought Management
Severe drought requires emergency feeding strategies:
- Monitor pasture availability weekly during drought
- Begin supplementation when pasture drops below 1,000 lbs dry matter per acre
- Consider early weaning calves to reduce cow nutritional demands
- Cull marginal cows early rather than feeding through extended drought
- Source alternative feeds (hay, silage, crop residues) before crisis hits
- Reduce stocking rates temporarily to match forage availability
Fall Diet: Building Reserves for Winter
🍂 Fall Feeding Overview
Fall represents the golden opportunity for cattle nutrition. Cooler temperatures combined with fall rains often trigger forage regrowth, while cattle's appetites return to normal. This season is critical for building body condition reserves that will carry cattle through winter and influence next year's reproductive success.
Fall Forage Quality
Fall forage often surprises producers with its quality. Cool-season grasses experience renewed vegetative growth, and early frost actually increases sugar content, improving palatability and energy density:
| Forage Type | Fall Protein % | Fall TDN % | Management Notes |
|---|---|---|---|
| Regrowth cool-season grass | 12-18% | 60-70% | Excellent quality, maximize use |
| Stockpiled fescue | 10-14% | 55-65% | Can extend grazing into winter |
| Annual ryegrass | 15-22% | 65-75% | Rapid growth, excellent for fall |
| Brassicas (turnips, kale) | 12-18% | 70-80% | High energy, gradual adaptation needed |
| Small grain forages | 15-20% | 65-70% | Oats, wheat, rye for fall grazing |
Body Condition Scoring Priority
Fall is your last chance to condition cattle before winter. Target body condition scores vary by cattle class and upcoming demands:
Fall BCS Targets
- Spring-calving cows: BCS 5-6 at breeding, maintain through fall
- Fall-calving cows: BCS 6 at calving, 5-6 through lactation
- Replacement heifers: BCS 6 entering winter to support growth
- Bulls: BCS 6 recovering from breeding season
- Stockers: BCS 5-6, prioritizing growth over conditioning
Economic Reality: Each BCS point gained in fall costs $30-50 in supplemental feed, but each point lost in winter costs $75-125 to regain due to cold stress and lower feed efficiency. Invest in fall conditioning!
Fall Feeding Strategies
Maximize fall's nutritional window with these proven strategies:
- Extended grazing: Utilize stockpiled forage to reduce hay feeding days by 30-60 days
- Limit feeding: Strip grazing or limit grazing to 4-6 hours daily on high-quality forage can extend pasture and improve utilization
- Wean strategically: Weaning calves reduces cow nutritional demands by 20-30%, allowing better conditioning on the same forage
- Energy supplementation: Adding 3-5 lbs grain daily for thin cows (BCS 4 or less) accelerates conditioning
- Forage testing: Test fall stockpiled forage to determine supplementation needs accurately
- Parasite control: Fall deworming improves feed efficiency by 10-15% in infected cattle
Annual Forages for Fall
Consider planting annual forages for fall grazing to extend the grazing season and reduce winter feeding costs:
Top Annual Forages for Fall Grazing
- Annual Ryegrass: Fast establishment (30-45 days), excellent quality, tolerates heavy grazing
- Oats: Cold tolerant, ready in 45-60 days, provides bulk and energy
- Turnips: High energy (80% TDN), deep roots break compaction, ready in 60-90 days
- Rape/Kale: Cold hardy, high protein, excellent for conditioning, avoid bloat risks
- Winter Wheat/Rye: Extend grazing into winter, can provide spring grazing too
Economic Impact: Annual fall forages typically cost $50-100 per acre to establish but can provide 2,000-4,000 lbs dry matter per acre, replacing hay at a fraction of the cost.
Crop Residue Utilization
Fall offers unique opportunities to utilize crop residues, providing economical feed sources:
| Crop Residue | Protein % | TDN % | Grazing Duration | Supplement Needs |
|---|---|---|---|---|
| Corn stalks | 5-7% | 50-55% | 60-90 days | Protein required |
| Wheat stubble | 4-6% | 45-50% | 30-45 days | Protein + energy |
| Soybean stubble | 8-10% | 48-52% | 20-30 days | Energy supplement |
| Sorghum residue | 4-6% | 45-50% | 45-60 days | Protein required |
Winter Diet: Survival and Maintenance
❄️ Winter Feeding Overview
Winter represents the most challenging and expensive feeding season. Stored feeds replace fresh forage, energy requirements increase due to cold stress, and feeding logistics become complicated by weather and frozen ground. Winter feed costs can represent 50-70% of annual feeding expenses despite lasting only 3-5 months in most regions.
Winter Energy Requirements
Cold stress dramatically increases cattle energy needs. The thermoneutral zone for cattle is 32-77°F. Below 32°F, maintenance energy requirements increase based on temperature and wind chill:
| Temperature | Energy Increase | Practical Adjustment | Daily Cost Impact |
|---|---|---|---|
| 20-32°F | +10% | Add 2-3 lbs hay | +$0.30-0.50 |
| 0-20°F | +20% | Add 4-6 lbs hay or 2 lbs grain | +$0.60-1.00 |
| Below 0°F | +30% | Add 6-9 lbs hay or 3-4 lbs grain | +$0.90-1.50 |
| Extreme cold + wind | +40-50% | Emergency feeding, provide shelter | +$1.20-2.00 |
Winter Feed Types and Quality
Winter feeding relies heavily on stored forages and supplements. Quality varies dramatically and directly impacts cattle performance and feed costs:
| Feed Type | Avg Protein % | Avg TDN % | Best Use | Daily Amount (1,200 lb cow) |
|---|---|---|---|---|
| Premium alfalfa hay | 18-22% | 60-65% | Lactating cows, growing cattle | 25-30 lbs |
| Good grass hay | 10-12% | 54-58% | Dry cows, general maintenance | 28-32 lbs |
| Average grass hay | 8-10% | 50-54% | Dry cows with supplement | 30-35 lbs |
| Poor quality hay | 5-8% | 45-50% | Avoid or heavily supplement | 35-40 lbs + supplement |
| Corn silage | 8-10% | 68-72% | High energy option | 40-50 lbs (as-fed) |
| Haylage | 12-16% | 58-65% | Quality alternative to hay | 35-45 lbs (as-fed) |
Winter Supplementation Strategy
Most winter hay requires supplementation to meet cattle needs. Strategic supplementation optimizes cattle health while controlling costs:
Supplement Selection Guide
When hay protein is below 8%:
- Add protein supplement (20-40% CP) at 1-3 lbs daily
- Options: soybean meal, cottonseed meal, distillers grains, or commercial protein tubs
- Cost: $0.40-1.20 per head per day
When hay TDN is below 50%:
- Add energy supplement at 2-5 lbs daily
- Options: whole corn, barley, beet pulp, or energy blocks
- Cost: $0.50-1.50 per head per day
For late-pregnancy cows (last 90 days):
- Increase total nutrition by 20-30%
- Focus on protein (10-12% of diet DM) and energy
- Ensures calf development and colostrum production
Winter Feeding Management
Proper winter feeding extends beyond nutrition to include practical management considerations:
- Feeding time: Feed in late afternoon/evening so cattle digest overnight, generating heat during coldest hours
- Windbreaks: Natural or artificial windbreaks reduce energy needs by 10-20% in cold winds
- Bedding: Provide dry bedding in severe cold; cattle lying on frozen ground lose significant heat
- Water access: Ensure ice-free water 24/7; dehydration reduces feed intake and causes stress
- Feed quality consistency: Avoid sudden changes; transition feeds over 7-10 days minimum
- Body condition monitoring: Check BCS monthly; adjust feeding if cattle losing condition
- Waste reduction: Use hay feeders to reduce waste from 25-30% to 5-15%
Winter Feeding Economics
Winter feeding represents your largest seasonal expense. Consider these cost-control strategies:
Cost-Saving Winter Strategies
- Buy hay in summer: Save 20-40% compared to mid-winter purchase
- Test all hay: $25 test prevents over-supplementing and saves hundreds per ton
- Use hay feeders: Reduce waste, pay for themselves in one season
- Extend fall grazing: Each extra grazing day saves $1.50-2.50 per cow
- Winter stockpiled forage: Reduces hay days by 30-60 days in many climates
- Cull strategically: Remove poor-doers before winter feeding begins
- Group feeding: Separate high-need cattle (late-pregnant, thin) from dry cows to avoid overfeeding
Emergency Winter Feeding
Severe weather may require emergency interventions:
| Weather Event | Cattle Response | Emergency Action |
|---|---|---|
| Ice storm | Cannot graze frozen pasture | Provide hay immediately; ensure water access |
| Deep snow (>12 inches) | Limited mobility, high energy use | Increase feed 20-30%; provide paths to water |
| Blizzard | Extreme cold stress | Provide windbreak; feed extra hay/grain |
| Extended cold (-10°F+) | Increased energy demands | Increase energy feeds 30-40%; check cattle twice daily |
Managing Seasonal Transitions
The transition periods between seasons present unique challenges and opportunities. Abrupt dietary changes stress cattle's digestive system and can cause health problems ranging from mild digestive upset to life-threatening acidosis or bloat.
Rumen Adaptation Requirements
The rumen microbiome requires time to adapt to new feed types. Different feeds support different microbial populations, and sudden changes can cause population crashes, reducing digestive efficiency and potentially causing disease.
| Feed Transition Type | Required Adaptation Time | Primary Risk | Transition Strategy |
|---|---|---|---|
| Hay to fresh pasture | 7-14 days | Bloat, scours | Limit grazing time initially, maintain hay access |
| Pasture to hay | 5-7 days | Reduced intake | Gradually reduce pasture access while offering hay |
| Low to high grain | 14-21 days | Acidosis, founder | Increase by max 1-2 lbs every 2-3 days |
| Dry to succulent feeds | 7-10 days | Digestive upset | Mix feeds, gradually shift ratios |
| Changing hay types | 3-5 days | Reduced intake | Mix old and new hays together |
Critical Transition Periods
Winter to Spring (Most Critical)
This transition presents the highest risk for nutritional disorders. The dramatic shift from dry, low-protein hay to lush, high-protein pasture challenges the rumen microbiome while grass tetany and bloat risks peak.
Best practices:
- Begin transition 2-3 weeks before planned full-time turnout
- Start with 2-3 hours grazing daily, increasing 1-2 hours every 2-3 days
- Feed hay before turning cattle onto pasture (full rumen reduces gorging)
- Provide high-magnesium minerals for 30 days before and after turnout
- Never turn hungry cattle onto lush legume pastures
- Monitor closely for tetany symptoms: muscle tremors, staggering, aggression
Summer to Fall
As heat stress subsides and appetites return, cattle may overeat if transitioned to rich fall forages too quickly, particularly brassicas or high-quality small grains.
Best practices:
- Limit initial access to rich fall annuals (4-6 hours daily)
- Provide long-stem hay alongside new forages
- Adapt cattle gradually to brassicas over 7-10 days (risk of bloat and scours)
- Monitor manure consistency as indicator of digestive adaptation
Fall to Winter
Transitioning from fresh forage to stored feeds requires adjustment but presents lower health risks than other transitions.
Best practices:
- Begin supplementing hay 2-3 weeks before ending grazing completely
- Gradually reduce pasture time while increasing hay availability
- Maintain mineral supplementation throughout transition
- Monitor body condition and increase feeding if cattle losing weight
Breed-Specific Considerations
Different cattle breeds have evolved for different climates and production systems, resulting in varying nutritional needs and seasonal adaptations. Understanding these differences optimizes feeding efficiency and animal welfare.
British vs. Continental Breeds
British Breeds (Angus, Hereford, Red Angus)
- Moderate frame size, early maturing
- Better cold tolerance due to hardiness
- Maintain condition on lower-quality forages
- Lower feed requirements per pound gained
- Ideal for forage-based systems
- Winter: Can thrive on medium-quality hay with minimal supplement
Learn more about British cattle breeds and specifically Angus cattle.
Continental Breeds (Limousin, Charolais, Simmental)
- Large frame, later maturing
- Higher growth potential and lean gain
- Require higher-quality nutrition
- Need more winter supplementation
- Excel in high-input feeding systems
- Winter: Require good-quality hay or significant supplementation
Discover more about Limousin breeds.
Dairy Breeds Seasonal Needs
Dairy cattle, particularly high-producing Holsteins, have dramatically different seasonal requirements due to lactation demands:
| Season | Dairy-Specific Challenges | Feeding Adjustments |
|---|---|---|
| Spring | Pasture protein excess causes milk urea nitrogen issues | Balance with energy supplements; monitor milk components |
| Summer | Heat stress dramatically reduces milk production | Increase energy density; provide cooling; adjust feeding times |
| Fall | Opportunity to improve body condition before calving | Maintain milk production while conditioning dry cows |
| Winter | High energy demands for milk + cold stress | Maximum quality feeds; precise supplementation critical |
Tropical and Heat-Adapted Breeds
Brahman, Brangus, and other heat-adapted breeds have different seasonal responses:
- Summer advantage: Thrive in heat that stresses British breeds; maintain intake and productivity
- Winter challenge: Less cold-tolerant; require more winter protection and energy
- Forage utilization: Excellent ability to utilize lower-quality forages year-round
- Parasite resistance: Better resistance to warm-season parasites affects summer productivity

Heritage and Minor Breeds
Heritage breeds like Dexter, Highland, and others often show superior seasonal adaptability due to less intensive selection for production traits:
Advantages of heritage breeds:
- Better foraging ability across seasons
- Hardiness in extreme weather
- Lower nutritional requirements
- Ability to maintain condition on marginal forages

Production Stage Impact on Seasonal Feeding
A cow's nutritional needs vary dramatically based on her production stage, and these stages often align with specific seasons, creating compounding nutritional challenges or opportunities.
Seasonal Production Alignment
| Production Stage | Typical Season | Nutritional Priority | Feeding Strategy |
|---|---|---|---|
| Calving | Spring or Fall | High energy + protein | Best quality feeds; prevent metabolic diseases |
| Early Lactation | Spring/Summer or Fall/Winter | Maximum energy + protein | Peak nutrition; may not meet needs from forage alone |
| Breeding | Late Spring/Summer | Moderate, consistent nutrition | Maintain BCS 5-6; flush thin cows |
| Mid-Pregnancy | Fall/Winter | Maintenance | Can utilize lower-quality feeds |
| Late Pregnancy | Winter/Spring | Increasing needs | Increase nutrition 20-30% last 90 days |
| Dry (non-lactating) | Varies | Maintenance | Most economical feeding; utilize lower-cost feeds |
Challenging Season-Stage Combinations
Winter Calving + Lactation
Challenge: Maximum nutritional demands coincide with highest feed costs and cold stress.
Strategy:
- Provide premium hay (alfalfa or high-quality grass)
- Supplement grain/protein at 3-5 lbs daily
- Ensure excellent body condition (BCS 6) at calving
- Provide windbreaks and shelter
- Budget $4-6 per head daily for feed
Spring Calving + Lactation
Advantage: Peak nutritional demands align with peak forage quality.
Strategy:
- Utilize lush spring pasture to minimize costs
- Most cows meet needs from pasture alone
- Provide high-magnesium minerals
- Monitor for grass tetany in high producers
- Feed costs can drop to $1.50-2.50 per head daily
Grouping Strategies
Feeding cattle in groups based on production stage and season improves efficiency and reduces costs:
- High-need group: Late-pregnant, early lactation, thin cows receive best feeds
- Moderate-need group: Mid-lactation, breeding cows receive good-quality feeds
- Low-need group: Dry, mid-pregnant cows in good condition can utilize lower-cost feeds
- Growing cattle: Separate group with consistent high-quality nutrition for growth
This strategy prevents overfeeding low-need cattle while ensuring high-need animals receive adequate nutrition, potentially reducing feed costs by 15-25%.
Cost-Effective Seasonal Strategies
Strategic seasonal feeding management can dramatically impact profitability. Here are proven approaches that successful operations use to optimize nutrition while controlling costs:
Extended Grazing Strategies
Economic Impact of Extended Grazing
Each additional day of grazing saves approximately $1.50-2.50 per cow compared to full hay feeding. Extending the grazing season by just 30 days saves $45-75 per cow, or $4,500-7,500 on a 100-cow herd.
Methods to extend grazing:
- Stockpile fescue: Rest paddocks from August through frost; graze November-January
- Winter annuals: Plant wheat, rye, or triticale in September for December-March grazing
- Brassicas: Plant turnips/kale in July-August for October-December grazing
- Strip grazing: Use temporary fencing to ration stockpiled forage, extending availability
- Bale grazing: Place hay bales in paddocks and limit access, reducing feeding labor
Feed Testing Investment
Feed testing represents one of the highest-ROI investments in cattle nutrition:
| Feed Test Cost | Information Gained | Typical Savings | ROI |
|---|---|---|---|
| $20-30 | Protein, energy, fiber content | $200-500 per 100 cows | 700-1,600% |
| $40-60 | Complete nutritional profile + minerals | $400-800 per 100 cows | 900-1,900% |
When to test feeds:
- Every hay cutting or field
- Silage at ensiling and at feeding
- Fall stockpiled forage before grazing begins
- Any time feed quality appears questionable
- When purchasing large quantities of feed
Strategic Supplementation
Supplement Cost-Benefit Analysis
Not all supplementation provides positive economic returns. Calculate whether supplementation is justified:
Example calculation:
Scenario: 100 beef cows, 120-day winter feeding period, considering protein supplementation
- Supplement cost: $0.75/head/day × 100 cows × 120 days = $9,000
- Expected benefit: Improved body condition (+0.5 BCS) worth $50-75/cow = $5,000-7,500
- Plus improved calf weaning weights: 15 lbs × 90 calves × $1.50/lb = $2,025
- Total benefit: $7,025-9,525
- Result: Marginal to positive return depending on prices
This illustrates why testing hay quality is critical—you may not need expensive supplements if hay quality is adequate!
Calving Season Alignment
Aligning calving season with forage availability can dramatically reduce feed costs:
Spring Calving (March-May)
Advantages:
- Peak lactation aligns with peak pasture
- Lowest feed costs during high-demand period
- Natural weaning time in fall
- Calves grow on quality summer/fall forage
Disadvantages:
- Calving during challenging weather
- Grass tetany risk management needed
- More labor-intensive calving season
Fall Calving (September-November)
Advantages:
- Calving during pleasant weather
- Calves marketed at higher weights
- Can utilize fall forage flush
- Breeding during summer on pasture
Disadvantages:
- Peak lactation during expensive winter
- Higher feed costs ($3-6/day vs $1.50-3/day)
- Requires premium nutrition year-round
Economic analysis: Spring calving typically costs $150-250 less per cow annually in feed expenses compared to fall calving, though market timing may offset this in some regions.
Waste Reduction Strategies
Feed waste represents hidden costs that can exceed supplement expenses:
| Feeding Method | Typical Waste % | 100-Cow Cost Impact (Winter) | Solution |
|---|---|---|---|
| Ground feeding (no feeder) | 25-45% | $4,000-7,000 lost | Install hay feeders immediately |
| Ring feeders (open bottom) | 15-25% | $2,400-4,000 lost | Add solid bottoms or sheeted rings |
| Cone feeders | 8-15% | $1,300-2,400 lost | Optimal for round bales |
| Cradle feeders | 6-12% | $1,000-1,900 lost | Good for square bales |
| Bunk feeders | 5-10% | $800-1,600 lost | Best for processed feeds |
Investment in quality hay feeders typically pays for itself in 1-2 seasons through waste reduction alone.
