# Working Equid Pasture and Forage Management ## Key Takeaways - **Rotational grazing is critical for preventing overgrazing, maintaining plant vigor, and reducing parasite burden by moving equids every 3-7 days and allowing paddocks 21-30 days of rest.** This practice ensures forage recovery and minimizes the ingestion of infective parasite larvae. - **Forage species selection must align with regional climate and equid physiology; cool-season grasses (timothy, orchardgrass) are suitable for temperate zones, while warm-season grasses (bermudagrass) are for hot climates, and legumes should be limited to <30% to prevent bloat.** Donkeys and mules require lower-energy forages due to their predisposition to obesity and laminitis. - **Identification and removal of toxic plants such as ragwort (pyrrolizidine alkaloids causing liver damage), bracken fern (thiaminase destroying thiamine), and red maple (wilted leaves causing hemolytic anemia) are paramount to prevent acute poisoning events.** Immediate veterinary consultation is required if toxic plant ingestion is suspected. - **Supplemental feeding with hay or concentrates is necessary when pasture quality declines, but overfeeding concentrates can lead to obesity, laminitis, and colic.** Hay should be fed at 1.5-2.5% of body weight for horses and 1-1.5% for donkeys/mules, with concentrate feeding based on workload and body condition score. - **Soil fertility management, including annual soil testing and pH adjustment (6.0-7.0 for cool-season grasses), is essential for supporting healthy pasture growth and nutrient content.** Neglecting soil fertility leads to poor forage quality, weed invasion, and reduced pasture productivity. - **A Pasture Condition Score (PCS) system (1-5) provides objective decision-making for grazing, with scores of 4-5 indicating readiness for grazing and scores of 2-3 necessitating rest or limited grazing.** Consistently low PCS scores (1-2) indicate severe degradation requiring renovation, potentially due to nutrient deficiencies, compaction, or toxic plant invasion. --- This article provides practical guidance for farmers managing pasture and forage for working horses, donkeys, and mules. It covers pasture establishment, rotational grazing, forage species selection, toxic plant identification, and supplemental feeding strategies. The goal is to help you maintain healthy, productive equids through evidence-based forage management. ## At a Glance | Management Area | Key Decision | Practical Outcome | |-----------------|--------------|-------------------| | Pasture Establishment | Select forage species adapted to your climate and soil type | Provides consistent, high-quality grazing and reduces reliance on purchased feed | | Rotational Grazing | Divide pasture into paddocks and rotate equids every 3-7 days | Prevents overgrazing, maintains plant vigor, and reduces parasite burden | | Forage Species Selection | Choose cool-season grasses (e.g., timothy, orchardgrass) or warm-season grasses based on region | Matches forage growth patterns to equid nutritional needs | | Toxic Plant Management | Identify and remove toxic plants (e.g., ragwort, bracken fern, red maple) | Prevents poisoning and associated health emergencies | | Supplemental Feeding | Provide hay or concentrate when pasture quality declines | Maintains body condition and prevents nutritional deficiencies | | Soil Fertility | Test soil annually and apply lime or fertilizer as needed | Supports healthy pasture growth and forage nutrient content | ## Pasture Establishment and Renovation Establishing or renovating a pasture requires careful planning to ensure long-term productivity. Begin with a soil test to determine pH, nutrient levels, and organic matter content. The [USDA Agricultural Research Service](https://www.ars.usda.gov/animal-production-and-protection) provides resources on soil management for forage production. Soil pH should be between 6.0 and 7.0 for most cool-season grasses and legumes. Apply lime according to soil test recommendations at least six months before seeding to allow pH adjustment. Select forage species based on your climate, soil type, and the nutritional needs of your equids. Cool-season grasses such as timothy, orchardgrass, and tall fescue are suitable for temperate regions. Warm-season grasses like bermudagrass and bahiagrass perform better in hot, humid climates. Legumes such as white clover and alfalfa can improve forage quality and fix nitrogen, but they require careful management to prevent bloat in equids. Prepare the seedbed by tilling or discing to a depth of 4-6 inches, then firm the soil with a cultipacker or roller. Broadcast or drill seed at the recommended rate for your chosen species. For cool-season grasses, seed in early fall or early spring. For warm-season grasses, seed in late spring after soil temperatures reach 60°F. Irrigate if necessary to ensure good seed-to-soil contact and germination. After establishment, allow the pasture to grow to a height of 6-8 inches before the first grazing. This allows root systems to develop fully. A survey of equine pasture management practices in southeast Pennsylvania found that many farms do not follow recommended soil fertility and grazing management protocols, leading to reduced pasture productivity ([Journal of equine veterinary science, 2026](https://pubmed.ncbi.nlm.nih.gov/41974256)). Regular soil testing and proper establishment practices can prevent these issues. ## Rotational Grazing Systems Rotational grazing involves dividing a pasture into multiple paddocks and moving equids between them on a schedule. This system prevents overgrazing, allows forage to recover, and reduces the buildup of internal parasites. A study on Florida horse operations found that pasture management practices vary widely, and many farms do not implement rotational grazing ([Journal of equine veterinary science, 2020](https://pubmed.ncbi.nlm.nih.gov/33276924)). Implementing a rotational system can improve forage utilization and equid health. Design your paddocks based on herd size, pasture area, and forage growth rate. A typical rotation schedule moves equids every 3-7 days during the growing season. Allow paddocks to rest for 21-30 days before regrazing. Use temporary fencing such as polytape or electric netting to create paddocks. Provide access to water and shelter in each paddock. Monitor forage height and quality before moving equids. Graze cool-season grasses when they reach 6-8 inches and stop grazing when they are grazed down to 3-4 inches. For warm-season grasses, graze at 8-12 inches and stop at 4-6 inches. Overgrazing below these heights damages plant crowns and reduces regrowth. Rotational grazing also helps manage parasite burdens. Equids ingest infective larvae while grazing, and larvae can survive on pasture for weeks to months. Moving equids to a fresh paddock before they graze too low reduces exposure. Resting paddocks for at least 30 days during warm, dry weather can break the parasite life cycle. ## Forage Species Selection for Equids Selecting the right forage species is critical for meeting the nutritional needs of working equids. Horses, donkeys, and mules have different digestive physiologies and nutrient requirements. Donkeys, for example, are more efficient at digesting fibrous forages and are prone to obesity and laminitis if fed high-energy pastures ([The Veterinary clinics of North America. Equine practice, 2009](https://pubmed.ncbi.nlm.nih.gov/19303549)). Cool-season grasses suitable for equids include timothy, orchardgrass, meadow fescue, and Kentucky bluegrass. These grasses provide moderate protein (10-15%) and energy levels. Tall fescue is also common but can be infected with an endophytic fungus that produces ergovaline, a toxin that causes fescue toxicosis in horses. A study on on-farm monitoring of ergovaline in tall fescue pastures found that toxin levels vary by season and management ([Toxins, 2021](https://pubmed.ncbi.nlm.nih.gov/34678976)). If you grow tall fescue, choose endophyte-free or novel endophyte varieties. Warm-season grasses such as bermudagrass, bahiagrass, and teff are suitable for hot climates. They have lower protein content (8-12%) but are highly digestible. Legumes like white clover and alfalfa can be included in pasture mixes to boost protein and calcium. However, legumes can cause bloat in equids if consumed in large quantities, so limit legume content to 30% or less of the pasture mix. For donkeys and mules, choose forages with lower energy density to prevent obesity. Native grasses or mixed-species pastures with higher fiber content are appropriate. A study on donkey grazing in Mediterranean landscapes found that donkeys effectively control biomass and increase floral diversity in pastures ([CATENA, 2023](https://doi.org/10.1016/j.catena.2023.107503)). This suggests that donkeys can be used for conservation grazing while meeting their nutritional needs. ## Toxic Plants and Pasture Safety Toxic plants pose a serious risk to working equids. Common toxic plants include ragwort (Senecio jacobaea), bracken fern (Pteridium aquilinum), red maple (Acer rubrum), and yew (Taxus baccata). Ragwort contains pyrrolizidine alkaloids that cause liver damage, and contamination of hay or feed with ragwort has caused poisoning outbreaks in horses ([Pesquisa Veterinaria Brasileira, 2025](https://doi.org/10.1590/1678-5150-PVB-7759en)). Remove ragwort by hand-pulling or herbicide application before it flowers. Bracken fern contains thiaminase, which destroys thiamine (vitamin B1) and causes neurological signs in horses. Red maple leaves, when wilted, cause hemolytic anemia. Yew contains taxine alkaloids that cause sudden cardiac death. Identify and remove these plants from pastures and along fence lines. Other toxic plants include oleander, rhododendron, and nightshade species. The [Merck Veterinary Manual](https://www.merckvetmanual.com/management-and-nutrition) provides a comprehensive list of toxic plants for equids. Regularly inspect pastures for new growth of toxic plants, especially after rain or soil disturbance. If you suspect your equid has ingested a toxic plant, contact a veterinarian immediately. Signs of poisoning include colic, diarrhea, lethargy, jaundice, and neurological abnormalities. Do not wait for symptoms to worsen. Remove the animal from the pasture and provide supportive care as directed by your veterinarian. ## Supplemental Feeding Strategies Supplemental feeding is necessary when pasture quality declines due to drought, winter dormancy, or overgrazing. Hay is the most common supplement for working equids. Choose hay that matches the nutritional needs of your animals. Grass hay (timothy, orchardgrass, brome) is suitable for most equids, while legume hay (alfalfa) is higher in protein and calcium and should be fed in moderation to donkeys and mules. Feed hay at a rate of 1.5-2.5% of body weight per day for horses, and 1-1.5% for donkeys and mules. Provide hay in a feeder or net to reduce waste and prevent soil contamination. Soaking hay for 30-60 minutes can reduce dust and sugar content for animals with respiratory issues or metabolic conditions. Concentrate feeds (grains, pellets) should be fed only when additional energy is needed for work, growth, or lactation. A survey of Ohio horse farms found that feeding practices vary widely, and many horses receive more concentrate than necessary ([Translational animal science, 2025](https://pubmed.ncbi.nlm.nih.gov/40666790)). Overfeeding concentrate can lead to obesity, laminitis, and colic. Base concentrate feeding on body condition score and workload. For donkeys and mules, limit concentrate feeding to avoid obesity. Provide a balanced mineral supplement with calcium, phosphorus, and salt. The [Food and Agriculture Organization](https://www.fao.org/animal-production/en) provides guidelines on equid nutrition and feeding management. ## Soil Fertility and Pasture Maintenance Maintaining soil fertility is essential for productive pasture. Test soil every 1-2 years to monitor pH, phosphorus, potassium, and organic matter. Apply lime to raise pH if needed. Apply nitrogen fertilizer in split applications during the growing season to promote grass growth. Use phosphorus and potassium based on soil test results. A survey of equine pasture management in southeast Pennsylvania found that many farms have low soil fertility and do not follow recommended fertilization practices ([Journal of equine veterinary science, 2026](https://pubmed.ncbi.nlm.nih.gov/41974256)). This leads to poor forage quality and weed invasion. Regular soil testing and fertilization can prevent these problems. Overseed thin or bare areas in the pasture to maintain ground cover. Use a no-till drill or broadcast seed and drag a harrow to improve seed-to-soil contact. Overseed cool-season grasses in early fall or early spring. Overseed warm-season grasses in late spring. Control weeds through mowing, grazing management, or herbicide application. Mow pastures to a height of 4-6 inches after each grazing rotation to control weeds and encourage uniform regrowth. Spot-treat persistent weeds with herbicides labeled for pasture use. Follow all label instructions for application rates and grazing restrictions. ## Pasture Rotation Planner A pasture rotation planner helps you schedule grazing and rest periods for optimal forage growth and equid health. Below is a sample rotation plan for a 10-acre pasture divided into 5 paddocks of 2 acres each, with 4 horses. | Paddock | Graze Period | Rest Period | Forage Height at Start | Forage Height at End | |---------|--------------|-------------|------------------------|----------------------| | 1 | Week 1 | Weeks 2-5 | 8 inches | 4 inches | | 2 | Week 2 | Weeks 3-6 | 8 inches | 4 inches | | 3 | Week 3 | Weeks 4-7 | 8 inches | 4 inches | | 4 | Week 4 | Weeks 5-8 | 8 inches | 4 inches | | 5 | Week 5 | Weeks 6-9 | 8 inches | 4 inches | Adjust the rotation schedule based on forage growth rate, which varies with season, rainfall, and temperature. During rapid growth in spring, you may need to graze for 3-5 days per paddock and rest for 21-25 days. During slow growth in summer, extend the rest period to 30-40 days. In winter, when pasture growth stops, provide hay and rest all paddocks. Keep records of grazing dates, forage heights, and weather conditions. This information helps you refine your rotation plan over time. A study on pasture management to minimize laminitis risk recommends using a rotation planner to control sugar intake in horses prone to laminitis ([The Veterinary clinics of North America. Equine practice, 2010](https://pubmed.ncbi.nlm.nih.gov/20699180)). ## Common Failure Patterns in Pasture Management Several common mistakes reduce pasture productivity and equid health. Overgrazing is the most frequent failure. Grazing pastures below 3 inches damages plant crowns, reduces root mass, and allows weeds to invade. Overgrazed pastures also have higher soil erosion and lower water infiltration. Under-resting paddocks is another common error. Forage needs at least 21 days of rest after grazing to regrow leaf area and replenish root reserves. Resting for less than 21 days leads to gradual pasture decline. A survey of Florida horse operations found that many farms do not rotate pastures at all, leading to overgrazing and poor forage quality ([Journal of equine veterinary science, 2020](https://pubmed.ncbi.nlm.nih.gov/33276924)). Neglecting soil fertility is a third failure. Without regular soil testing and fertilization, pastures become nutrient-deficient and produce low-quality forage. Weeds and toxic plants then invade. A survey in Pennsylvania found that many farms have low soil phosphorus and potassium levels ([Journal of equine veterinary science, 2026](https://pubmed.ncbi.nlm.nih.gov/41974256)). Feeding too much concentrate is a fourth failure. Overfeeding grain or pellets can cause obesity, laminitis, and colic. Base concentrate feeding on body condition score and workload, not on habit. A survey of Ohio horse farms found that many horses receive more concentrate than recommended ([Translational animal science, 2025](https://pubmed.ncbi.nlm.nih.gov/40666790)). ## Welfare and Safety Context Proper pasture and forage management directly affects equid welfare. The [World Organisation for Animal Health](https://www.woah.org/en/what-we-do/animal-health-and-welfare/animal-welfare) emphasizes that good nutrition and housing are fundamental to animal welfare. Pasture provides exercise, social interaction, and natural foraging behavior, all of which improve mental and physical health. Laminitis is a painful and potentially fatal condition linked to pasture management. High-sugar grasses, especially in spring and after frost, can trigger laminitis in susceptible equids. A study on pasture-associated laminitis found that management practices such as limiting grazing time and using grazing muzzles can reduce risk ([The Veterinary clinics of North America. Equine practice, 2009](https://pubmed.ncbi.nlm.nih.gov/19303549)). Monitor body condition and adjust grazing access accordingly. Equine grass sickness is a rare but serious neurological condition associated with grazing certain pastures. Research suggests that edaphic (soil) and phytochemical factors may predict risk ([Frontiers in Pharmacology, 2010](https://doi.org/10.3389/fphar.2010.00122)). If you suspect grass sickness, contact a veterinarian immediately. Donkeys and mules have unique welfare needs. They are prone to obesity and laminitis on rich pastures. Provide low-energy forages and limit grazing time. A study on donkey grazing in Mediterranean landscapes found that donkeys can maintain body condition on poor-quality pastures while controlling biomass ([CATENA, 2023](https://doi.org/10.1016/j.catena.2023.107503)). This suggests that donkeys are well-suited to conservation grazing. ## Records and Measurements Keep detailed records of pasture management activities. Record soil test results, fertilizer applications, seeding dates, and grazing rotations. Measure forage height before and after grazing. Note weather conditions, including rainfall and temperature. These records help you evaluate pasture performance and make adjustments. Record equid body condition scores monthly. Use a 1-9 scale for horses and a 1-5 scale for donkeys. Adjust feeding and grazing management based on body condition. Record any health issues, such as colic, laminitis, or weight loss, and note their possible connection to pasture management. Record hay and concentrate purchases, including type, quantity, and cost. This helps you calculate feed costs and evaluate the economic efficiency of your pasture management. A study on Ohio horse farms found that feed costs are a significant expense for many operations ([Translational animal science, 2025](https://pubmed.ncbi.nlm.nih.gov/40666790)). ## Professional Escalation Criteria Consult a veterinarian if you observe signs of laminitis, colic, weight loss, or toxic plant poisoning. Signs of laminitis include reluctance to move, heat in the hooves, and a bounding digital pulse. Signs of colic include pawing, rolling, and looking at the flank. Signs of toxic plant poisoning include jaundice, lethargy, and neurological abnormalities. Consult an equine nutritionist if you need help formulating a feeding program for working equids. A nutritionist can analyze your forage and recommend appropriate supplements. The [USDA National Agricultural Library](https://www.nal.usda.gov/animal-health-and-welfare) provides resources on animal nutrition and feeding management. Consult an agronomist or extension agent if you need help with pasture establishment, soil fertility, or weed control. They can provide soil testing services and recommend appropriate forage species for your region. The [Food and Agriculture Organization](https://www.fao.org/dad-is) offers resources on pasture management and animal production. ## Pasture Condition Scoring and Adaptive Management Framework A systematic pasture condition scoring system enables you to make objective grazing decisions based on measurable field observations instead of guesswork. This framework complements rotational grazing by providing clear thresholds for when to move equids, when to rest paddocks, and when to intervene with renovation or supplemental feeding. The approach integrates forage height measurements, species composition estimates, and soil surface assessments into a single actionable score. ### Pasture Condition Score Definitions Assign a score of 1 to 5 for each paddock before grazing and after each rotation. Score 1 indicates severely degraded pasture requiring immediate rest and renovation. Score 5 represents optimal pasture condition with high forage quality and density. Use the following criteria for each score level. Score 5 (Optimal): Forage height is 8-12 inches for cool-season grasses or 10-14 inches for warm-season grasses. Desired forage species make up more than 80% of the plant cover. No bare soil is visible. No weed or toxic plant presence. Soil feels firm underfoot with no poaching damage. This paddock is ready for grazing. Score 4 (Good): Forage height is 6-8 inches for cool-season grasses or 8-10 inches for warm-season grasses. Desired species make up 60-80% of cover. Less than 5% bare soil. Occasional weeds present but no toxic plants. Minor poaching near gates or water sources. Grazing can begin but monitor closely. Score 3 (Fair): Forage height is 4-6 inches for cool-season grasses or 6-8 inches for warm-season grasses. Desired species make up 40-60% of cover. Bare soil patches cover 5-15% of the paddock. Weeds are common but not [dominant](/blog/careers/dominant-definition-biology). Some poaching in high-traffic areas. This paddock needs rest before grazing or only short grazing periods. Score 2 (Poor): Forage height is 2-4 inches. Desired species make up 20-40% of cover. Bare soil covers 15-30% of the paddock. Weeds or undesirable species are dominant. Poaching is widespread. Do not graze this paddock. Apply rest, overseeding, and soil fertility correction. Score 1 (Severely Degraded): Forage height is less than 2 inches. Desired species make up less than 20% of cover. Bare soil exceeds 30%. Erosion or gullying may be visible. Toxic plants may be present. This paddock requires complete renovation including tillage, soil amendment, and reseeding. Do not graze for at least one full growing season. ### Adaptive Management Decision Rules Use the pasture condition score to guide daily and weekly management decisions. The following rules apply during the growing season when forage is actively growing. If the pre-grazing score is 5 or 4, begin grazing as planned. Move equids to the next paddock when the post-grazing score reaches 3 or when forage height drops to 3-4 inches for cool-season grasses or 4-6 inches for warm-season grasses. Do not allow grazing below score 3, as this damages plant crowns and reduces regrowth potential. If the pre-grazing score is 3, delay grazing for 7-14 days if possible. If grazing is necessary due to limited paddock availability, limit grazing to 2-3 days and provide supplemental hay to reduce grazing pressure. Monitor forage height daily and move equids as soon as the post-grazing score reaches 2. If the pre-grazing score is 2 or 1, do not graze. Apply rest for a minimum of 30 days for score 2 paddocks or a full growing season for score 1 paddocks. During rest, mow to control weeds, apply fertilizer based on soil test results, and overseed with appropriate forage species. A survey of equine pasture management practices in southeast Pennsylvania found that many farms do not follow recommended soil fertility protocols, leading to degraded pastures that require extensive renovation ([Journal of equine veterinary science, 2026](https://pubmed.ncbi.nlm.nih.gov/41974256)). ### Seasonal Adjustment Factors Adjust your condition score thresholds based on season and forage growth rate. During spring rapid growth, you can graze paddocks at score 4 or 5 for 5-7 days and still achieve good regrowth. During summer slow growth, graze only score 5 paddocks and limit grazing to 3-4 days. During autumn, graze score 4 or 5 paddocks but allow longer rest periods of 30-40 days to build root reserves before winter dormancy. During winter dormancy, pasture condition scoring shifts focus to soil protection instead of forage growth. Score paddocks based on ground cover and poaching risk. Do not graze any paddock with a score below 3 during wet or frozen conditions, as this causes long-term soil compaction and turf damage. Provide hay in a designated sacrifice area or dry lot to protect pasture health. ### Record Keeping for Condition Scores Maintain a pasture condition log for each paddock. Record the date, pre-grazing score, post-grazing score, forage height measurements, and any observations about weed presence, poaching, or soil condition. Note weather conditions including rainfall amounts and temperature extremes. These records allow you to track pasture health trends over multiple seasons and identify paddocks that consistently score low. A study on pasture management to minimize laminitis risk recommends using detailed grazing records to control sugar intake in susceptible equids ([The Veterinary clinics of North America. Equine practice, 2010](https://pubmed.ncbi.nlm.nih.gov/20699180)). Your condition score records serve the same purpose by documenting when and where equids grazed high-quality forage that may trigger metabolic issues. ### Troubleshooting Low Condition Scores If a paddock consistently scores 2 or 3 despite following recommended rest periods, investigate underlying causes. Conduct a soil test to check for nutrient deficiencies or pH imbalance. Low phosphorus or potassium levels are common in overgrazed pastures and limit forage regrowth ([Journal of equine veterinary science, 2026](https://pubmed.ncbi.nlm.nih.gov/41974256)). Apply lime if pH is below 6.0 for cool-season grasses or below 5.5 for warm-season grasses. Check for soil compaction by inserting a metal rod or soil probe into the ground. If you cannot push it deeper than 4 inches without significant force, compaction is limiting root growth. Aerate compacted paddocks with a core aerator or shallow tillage before overseeding. Evaluate your stocking rate. If you have more equids than your pasture can support, even perfect management will not maintain condition scores above 3. Calculate your carrying capacity based on forage yield estimates for your region. A general guideline is 1-2 acres per horse for moderate grazing, but this varies with climate, soil fertility, and management intensity. The [Food and Agriculture Organization](https://www.fao.org/animal-production/en) provides resources on calculating carrying capacity for different production systems. Inspect for toxic plant invasion as a cause of low condition scores. Ragwort, bracken fern, and other toxic species can outcompete desirable forages in degraded pastures. Remove these plants before they spread further. A study on horse feed contamination by monocrotaline in Brazil highlighted the severe consequences of toxic plant ingestion ([Pesquisa Veterinaria Brasileira, 2025](https://doi.org/10.1590/1678-5150-PVB-7759en)). Regular pasture inspection and removal of toxic plants is essential for both pasture health and equid safety. ### Integrating Condition Scores with Supplemental Feeding Decisions Use pasture condition scores to determine when supplemental feeding is necessary. When the average condition score across all paddocks drops below 3, pasture alone cannot meet the nutritional needs of working equids. Begin feeding hay at 1.5-2.5% of body weight per day for horses and 1-1.5% for donkeys and mules. Continue supplemental feeding until paddock scores recover to 4 or higher. For donkeys and mules, condition scores are especially important because these species are prone to obesity on high-quality pasture. A score of 4 or 5 on a rich grass-legume mix may provide too much energy for donkeys. In this case, limit grazing time to 2-4 hours per day or use a grazing muzzle. Provide hay in a slow-feed net to extend foraging time without excess calorie intake. Research on donkey grazing in Mediterranean landscapes found that donkeys maintain body condition on lower-quality forages while effectively controlling biomass ([CATENA, 2023](https://doi.org/10.1016/j.catena.2023.107503)). This suggests that donkeys can thrive on pastures with condition scores of 3 or 4, provided the forage is appropriate for their digestive physiology. ### Professional Escalation Based on Condition Scores If a paddock remains at score 1 or 2 for more than one growing season despite corrective actions, consult an agronomist or extension agent. They can perform detailed soil analysis, recommend specific forage species for renovation, and advise on drainage improvements if waterlogging is an issue. The [USDA Agricultural Research Service](https://www.ars.usda.gov/animal-production-and-protection) provides resources on pasture renovation and soil management. If multiple paddocks consistently score 2 or 3 and your equids are losing body condition or showing signs of nutritional deficiency, consult an equine nutritionist. They can evaluate your feeding program and recommend adjustments to hay quality, concentrate feeding, or mineral supplementation. The [Merck Veterinary Manual](https://www.merckvetmanual.com/management-and-nutrition) provides guidance on nutritional assessment and feeding management for working equids. If you observe signs of laminitis, colic, or toxic plant poisoning in equids grazing paddocks with condition scores of 4 or 5, contact a veterinarian immediately. High-quality pasture can trigger laminitis in susceptible equids, especially during spring growth or after frost ([The Veterinary clinics of North America. Equine practice, 2009](https://pubmed.ncbi.nlm.nih.gov/19303549)). Your condition score records will help the veterinarian understand the grazing history and identify potential triggers. ## Frequently Asked Questions ### What is the best grass for horse pasture? The best grass depends on your climate and soil. Cool-season grasses like timothy, orchardgrass, and meadow fescue are suitable for temperate regions. Warm-season grasses like bermudagrass and bahiagrass perform well in hot climates. Choose endophyte-free tall fescue if you grow it. Legumes like white clover can be included in moderation. ### How often should I rotate horses on pasture? Rotate horses every 3-7 days during the growing season. Allow paddocks to rest for 21-30 days before regrazing. Adjust the rotation schedule based on forage growth rate. During rapid spring growth, graze for 3-5 days and rest for 21-25 days. During slow summer growth, extend the rest period to 30-40 days. ### Can donkeys eat the same pasture as horses? Donkeys can eat the same pasture as horses, but they require lower-energy forages to prevent obesity. Choose pastures with higher fiber content and lower sugar levels. Limit grazing time on rich pastures and provide hay instead. Donkeys are more efficient at digesting fibrous forages and can maintain body condition on poorer-quality pasture. ### What toxic plants should I remove from my pasture? Remove ragwort, bracken fern, red maple, yew, oleander, rhododendron, and nightshade species. These plants can cause liver damage, neurological signs, hemolytic anemia, or sudden death. Regularly inspect pastures for new growth of toxic plants, especially after rain or soil disturbance. ### How do I test my pasture soil? Collect soil samples from multiple locations in the pasture, mix them together, and send them to a soil testing laboratory. Test for pH, phosphorus, potassium, and organic matter. Follow the laboratory's recommendations for lime and fertilizer application. Test soil every 1-2 years. ### How much hay should I feed my horse? Feed hay at a rate of 1.5-2.5% of body weight per day for horses. For a 1,000-pound horse, this equals 15-25 pounds of hay per day. For donkeys and mules, feed 1-1.5% of body weight per day. Adjust the amount based on body condition score and workload. ### What is the best way to prevent laminitis in pasture-kept horses? Limit grazing time on high-sugar pastures, especially in spring and after frost. Use a grazing muzzle to reduce intake. Provide hay before turning out to pasture to slow consumption. Monitor body condition and adjust grazing access accordingly. Consult a veterinarian if you suspect laminitis. ### How do I control weeds in my pasture without chemicals? Mow pastures to a height of 4-6 inches after each grazing rotation to control weeds. Maintain dense, healthy pasture through proper fertilization and grazing management. Hand-pull persistent weeds like ragwort before they flower. Overseed thin areas to prevent weed invasion. ## Related Farming Guides - [Livestock Nutrition And Feed Management A Cross Species Decision Framework](/knowledge/animal-farming/farm-management/livestock-nutrition-and-feed-management-a-cross-species-decision-framework) - [Livestock Waste Management Composting Anaerobic Digestion Nutrient Recovery](/knowledge/animal-farming/farm-management/livestock-waste-management-composting-anaerobic-digestion-nutrient-recovery) - [Camel Breeding Management Genetics Reproduction](/knowledge/animal-farming/alternative-livestock/camel-breeding-management-genetics-reproduction) - [Rabbit Cage And Colony Housing Decisions Welfare Hygiene And Management](/knowledge/animal-farming/rabbits/rabbit-cage-and-colony-housing-decisions-welfare-hygiene-and-management) - [Poultry Genetics And Breeding Selection Strategies For Production Traits](/knowledge/animal-farming/poultry/poultry-genetics-and-breeding-selection-strategies-for-production-traits) ## Related Clinical & Scientific Guides * [Water Buffalo Genetic Improvement and Breeding Programs](/knowledge/animal-farming/alternative-livestock/water-buffalo-genetic-improvement-breeding-programs) * [Camel Farm Biosecurity: Disease Prevention and Quarantine Protocols](/knowledge/animal-farming/alternative-livestock/camel-farm-biosecurity-disease-prevention-quarantine-protocols) * [Water Buffalo Farm Equipment and Infrastructure](/knowledge/animal-farming/alternative-livestock/water-buffalo-farm-equipment-infrastructure) ## References and Further Reading - [www.woah.org](https://www.woah.org/en/what-we-do/animal-health-and-welfare/animal-welfare) - [www.fao.org](https://www.fao.org/dad-is) - [www.merckvetmanual.com](https://www.merckvetmanual.com/management-and-nutrition) - [FAO Animal Production and Health](https://www.fao.org/animal-production/en).
