Sheep Flock Planning: Calculating Stocking Rates and Pasture Rotation

Stocking rate is the number of sheep a pasture can support over a defined grazing period without degrading forage, soil, or animal condition. This article provides a practical framework for calculating stocking rates per acre based on pasture quality, sheep body weight, and grazing system, with a worksheet for planning rotational grazing. The guidance applies to farm owners, shepherds, farm employees, veterinarians, advisers, and students who need defensible numbers for grazing decisions. The methods described here use direct measurements you can take on your own farm, and they align with the broader principles of animal production and health promoted by the Food and Agriculture Organization of the United Nations.

Why Stocking Rate Determines Flock Health and Pasture Persistence

Stocking rate is the single most influential management decision in sheep grazing systems. It affects how much forage each animal can consume, how quickly pastures recover after grazing, and how much manure is distributed across the land. When stocking rate is too high, sheep consume forage faster than it regrows, pasture composition shifts toward less productive species, and animals lose body condition. When stocking rate is too low, forage is wasted, and pasture quality declines as plants mature and become less digestible.

The relationship between stocking rate and pasture production is not linear. Research on Australian sheep farms found that whole-farm stocking rate and rainfall exerted a stronger influence on pasture production, soil organic carbon, greenhouse gas emissions, and profit than pasture diversity or grazing management alone. This finding, published in Regenerative agriculture improves productivity and profitability while reducing greenhouse gas emissions on Australian sheep farms, underscores that getting the base stocking rate right matters more than fine-tuning grazing methods. The same study noted that low-intensity grazing with short rest periods was generally more profitable, while adaptive multi-paddock grazing promoted greater pasture growth and soil carbon accrual. Persistent trade-offs between economic and environmental outcomes mean you must decide which objective matters most for your farm.

For sheep farmers, the practical implication is clear. Calculate your stocking rate from measured pasture growth and sheep demand, then adjust based on observed animal condition and pasture residuals. Do not rely on regional averages or neighbor recommendations without verifying them against your own paddocks.

Core Principles of Stocking Rate Calculation

Animal Unit Equivalents for Sheep

Stocking rate calculations require a common unit to compare different classes of sheep. The standard reference is the animal unit, which represents one mature cow weighing approximately 1,000 pounds. Sheep are smaller, so they are expressed as fractions of an animal unit. A mature ewe weighing 150 pounds is typically considered 0.15 to 0.20 animal units, depending on the standard used in your region.

For practical purposes, you can calculate sheep equivalents directly. One mature ewe with a lamb at foot consumes more than a dry ewe of the same weight. A ram during breeding season has different energy demands than the same ram outside the breeding season. Lambs grow rapidly and their intake increases week by week. Your stocking rate calculation must account for these differences.

The simplest approach is to use metabolic body weight, which is body weight raised to the 0.75 power. This accounts for the fact that smaller animals require more feed per unit of body weight than larger animals. For a flock with mixed age groups, calculate the metabolic weight of each class, sum them, and divide by the metabolic weight of your reference animal.

Forage Demand per Sheep per Day

A mature ewe will consume approximately 3 to 4 percent of her body weight in dry matter per day. A 150-pound ewe therefore needs 4.5 to 6 pounds of dry matter daily. Lactating ewes with lambs may consume up to 5 percent of body weight in dry matter. Lambs consume less in absolute terms but more per unit of body weight.

Forage demand changes across the production cycle. Ewes in late pregnancy have increased energy requirements because the growing lambs occupy abdominal space and reduce rumen capacity. Lactating ewes have the highest energy demand of any point in the production cycle. Dry ewes in early pregnancy have the lowest demand. Your stocking rate calculation should use the highest demand period for the grazing season to avoid underfeeding at critical times.

Pasture Supply and Growth Rates

Pasture supply is measured as pounds of dry matter per acre. You can estimate this by clipping and weighing forage from known areas, or by using a pasture stick or rising plate meter calibrated to your pasture type. The key measurement is the amount of forage available at the start of grazing and the rate at which it regrows during the rest period.

Pasture growth rates vary by season, rainfall, soil fertility, and species composition. Cool-season grasses grow most in spring and fall. Warm-season grasses grow most in summer. Legumes add nitrogen and improve forage quality but require specific management to persist. Your stocking rate must match the slowest growth period of the year, or you must provide supplemental feed during those periods.

The USDA Agricultural Research Service conducts ongoing research on animal production and protection, including pasture management systems. Their work supports the principle that forage measurement, not guesswork, should drive stocking decisions.

At a Glance: Stocking Rate Decision Table

Grazing System Typical Stocking Rate (ewes per acre) Rest Period Between Grazing Events Best Suited For Primary Risk
Continuous grazing 2 to 4 mature ewes No rest period Low-cost management, small flocks Pasture degradation, selective grazing, parasite buildup
Rotational grazing with multiple paddocks 4 to 8 mature ewes 21 to 45 days depending on growth Flocks with fencing infrastructure Labor for moving fences, water access in each paddock
Adaptive multi-paddock grazing 8 to 15 mature ewes in short grazing bouts Variable, based on forage growth and recovery Farmers seeking soil carbon and biodiversity benefits Requires daily monitoring and flexible decision making

The ranges in this table are starting points, not prescriptions. Your actual stocking rate depends on pasture productivity, rainfall, soil type, and sheep class. Use the calculation worksheet below to determine your specific rate.

Calculating Your Stocking Rate: A Step by Step Worksheet

Step 1: Measure Available Forage

Walk each paddock and estimate forage mass using a rising plate meter, pasture stick, or clipped samples. Take at least 20 measurements per paddock and average them. Record the average in pounds of dry matter per acre. Do this at the same time of day and after the same amount of time since last grazing to keep measurements comparable.

For clipped samples, use a 1 square foot quadrat. Clip forage to grazing height, dry it in an oven or microwave, and weigh it. Multiply the dry weight by 43,560 to get pounds of dry matter per acre. This method is more accurate than visual estimation but takes more time.

Step 2: Determine the Grazing Window

Decide how many days you want sheep to graze a given paddock. In rotational systems, this is typically 1 to 7 days. Shorter grazing periods allow more uniform forage utilization but require more frequent moves. Longer grazing periods reduce labor but increase the risk of selective grazing and regrowth damage.

The grazing window also depends on the rest period required for pasture recovery. Cool-season grasses need 21 to 45 days of rest depending on temperature and moisture. Warm-season grasses need 30 to 60 days. Legumes need longer rest periods to rebuild root reserves. Your grazing window multiplied by the number of paddocks must equal or exceed the rest period.

Step 3: Calculate Paddock Carrying Capacity

Use this formula to calculate how many sheep a paddock can support for a given grazing period:

Available forage per acre (pounds dry matter) x grazeable area (acres) x utilization rate = total available forage

Total available forage divided by (sheep daily intake x grazing days) = number of sheep supported

The utilization rate is the proportion of available forage you are willing to let sheep consume. In continuous grazing, this is often 30 to 40 percent because sheep cannot be forced to eat everything uniformly. In rotational grazing, utilization can reach 50 to 60 percent because sheep are confined to a smaller area. Leaving at least 1,000 to 1,200 pounds of dry matter per acre as residual protects plant regrowth and soil.

Step 4: Adjust for Sheep Class and Stage of Production

Multiply the number of sheep supported by adjustment factors for your specific flock. A lactating ewe with twins consumes more than a dry ewe. A growing lamb consumes less than a mature ewe but more per unit of body weight. Use metabolic weight to standardize across classes.

For example, if your calculation says the paddock supports 10 mature dry ewes, and your flock consists of lactating ewes with lambs, reduce the number to 7 or 8 because each lactating ewe with lamb consumes more forage. If your flock consists of weaned lambs, you may be able to run more animals because each lamb consumes less total forage.

Step 5: Build in a Safety Margin

Pasture growth is variable. Drought, cold snaps, and insect damage can reduce forage supply quickly. Build a safety margin of 15 to 20 percent into your stocking rate calculation. This means stocking fewer animals than the calculation suggests, or planning to provide supplemental feed when growth slows.

The safety margin also protects against measurement error. Forage estimation methods have inherent inaccuracy, and pasture growth rates are difficult to predict. A conservative stocking rate is easier to adjust upward than an excessive rate is to correct after pasture damage occurs.

Rotational Grazing Plans for Sheep Flocks

Designing Paddock Layout

Rotational grazing requires dividing pasture into multiple paddocks and moving sheep through them on a schedule. The number of paddocks depends on the rest period your pasture needs and the grazing period you want to use. Divide the rest period by the grazing period to get the minimum number of paddocks. For a 30 day rest period and a 3 day grazing period, you need at least 10 paddocks.

Paddock size depends on flock size and stocking density. A larger flock needs larger paddocks or shorter grazing periods. The key is to match paddock size to the amount of forage sheep will consume in the grazing period. Sheep should enter a paddock with adequate forage and leave with the target residual.

Water access is a practical constraint in rotational systems. Sheep need clean water daily, and moving water to each paddock adds labor. Options include permanent water lines to each paddock, portable water tanks moved with the flock, or access lanes that allow sheep to reach a central water source. The USDA National Agricultural Library provides resources on animal health and welfare that include considerations for grazing management infrastructure.

Setting Grazing and Rest Periods

Grazing period should be short enough that sheep cannot selectively graze preferred plants and return to regrowth before it recovers. A 1 to 3 day grazing period is common in intensive rotational systems. Longer periods of 5 to 7 days work in less intensive systems but increase the risk of regrowth grazing.

Rest period should be long enough for plants to replenish carbohydrate reserves and regrow to grazing height. The actual rest period depends on temperature, moisture, and plant species. In spring with adequate moisture, cool-season grasses may need only 21 days. In summer heat or drought, they may need 45 days or more. Monitor pasture regrowth and adjust the rotation schedule accordingly.

Using Virtual Fencing for Strip Grazing

Virtual fencing is an emerging technology for managing grazing livestock. Animals wear GNSS collars that emit audio warnings when they approach a virtual boundary, followed by an electrical pulse if they ignore the warning. Research on beef cattle found that strip grazing managed with virtual fencing did not affect overall time spent grazing, ruminating, or resting compared to continuous stocking, and did not increase chronic stress as measured by hair cortisol content. The study, published as Daily behavioral grazing patterns of beef cattle: continuous stocking grazing vs. strip grazing managed by virtual fencing, found behavioral shifts in when animals grazed and rested, but no negative welfare effects.

For sheep farmers, virtual fencing offers the ability to create temporary paddocks without permanent fence lines. This can reduce fencing costs and allow more flexible grazing management. However, the technology requires reliable GNSS coverage, battery management for collars, and training for animals to learn the audio warning system. Consider whether the labor savings justify the equipment cost for your operation.

Options and Tradeoffs in Grazing Systems

Continuous Grazing

Continuous grazing keeps sheep on the same pasture for the entire grazing season. It requires the least fencing and labor. Sheep select preferred plants and leave less palatable species, which can shift pasture composition over time. Parasite burdens tend to be higher because sheep graze close to their own manure. Pasture utilization is lower because sheep do not graze uniformly.

Continuous grazing works best on large pastures with low stocking rates where forage supply exceeds demand for most of the season. It is a reasonable choice for small flocks or farms where labor is limited. The main risk is pasture degradation from overgrazing during slow growth periods.

Rotational Grazing

Rotational grazing divides pasture into paddocks and moves sheep through them on a schedule. It improves pasture utilization, allows rest periods for regrowth, and can reduce parasite burdens by moving sheep away from contaminated pasture. The study on gastrointestinal nematode control in sheep found that a non-chemical parasite management strategy based on rotational grazing, where sheep were relocated to a new pasture when grass height fell below 10 centimeters, combined with quarterly veterinary monitoring, maintained acceptable parasite levels while supporting body condition. Sheep in the rotational grazing group had higher body condition scores than sheep receiving routine anthelmintic treatment, despite having higher fecal egg counts.

Rotational grazing requires more fencing, water infrastructure, and labor than continuous grazing. The benefits include better pasture persistence, higher forage utilization, and potentially reduced reliance on chemical parasite control. The tradeoff is increased management intensity.

Adaptive Multi-Paddock Grazing

Adaptive multi-paddock grazing is a form of rotational grazing where paddock size, grazing period, and rest period are adjusted frequently based on forage growth and animal condition. It requires daily monitoring and flexible decision making. The Australian sheep farm study found that adaptive multi-paddock grazing promoted greater pasture growth, soil organic carbon accrual, and emissions abatement compared to low-intensity grazing. However, low-intensity grazing with short rest periods was generally more profitable, and the grazing regimes delivering the greatest soil carbon accrual were not necessarily the most profitable.

For sheep farmers interested in soil health and carbon sequestration, adaptive multi-paddock grazing offers potential environmental benefits. The tradeoff is lower profitability in some contexts and higher management demands. Decide which outcomes matter most for your farm before adopting this system.

Observations and Measurements for Grazing Decisions

Body Condition Scoring

Body condition scoring is a hands-on method for assessing whether sheep are getting enough nutrition. Run your hand over the sheep's loin area and feel the amount of muscle and fat cover. Scores range from 1 (emaciated) to 5 (obese). A score of 3 is ideal for most production stages. Ewes should not lose more than half a condition score during lactation, and they should regain condition before the next breeding season.

Body condition scoring is more reliable than visual appraisal alone, especially in sheep with heavy fleeces. Score a sample of at least 10 percent of the flock at regular intervals, including before breeding, before lambing, and at weaning. Record scores and track changes over time. Declining condition scores indicate that stocking rate is too high or forage quality is insufficient.

Pasture Residual Monitoring

Pasture residual is the amount of forage left after grazing. It is the best indicator of whether stocking rate matches forage supply. Walk each paddock after sheep are moved and estimate the residual forage mass. Target residuals vary by pasture type, but a general guideline is to leave 1,000 to 1,200 pounds of dry matter per acre for cool-season grasses. Leaving too much residual wastes forage. Leaving too little damages plant regrowth and reduces future pasture production.

Record residuals for each paddock after each grazing event. Compare residuals across paddocks and grazing periods. Consistent residuals indicate a well-matched stocking rate. Declining residuals over time indicate overstocking. Increasing residuals indicate understocking or declining forage quality.

Fecal Egg Counts

Fecal egg counts measure the level of gastrointestinal nematode infection in sheep. High counts indicate that parasite burdens are building, which can happen when stocking rates are high and pastures are contaminated. The rotational grazing parasite study demonstrated that rotational grazing combined with veterinary monitoring can maintain acceptable parasite levels without routine anthelmintic treatment. Sheep in the rotational group had higher fecal egg counts than treated sheep but maintained higher body condition scores, suggesting that moderate parasite burdens may be tolerable when nutrition is adequate.

Work with your veterinarian to establish a fecal egg count monitoring schedule. Sample a representative group of sheep, beyond the sick or thin ones. Use the results to make grazing decisions, such as moving sheep to clean pasture or extending rest periods to break the parasite life cycle. The World Organisation for Animal Health provides international standards for animal health and welfare that include guidance on parasite management.

Records and Measurements for Flock Planning

Essential Records to Keep

Maintain a grazing record for each paddock that includes the date sheep entered and left, the number and class of sheep, estimated forage supply at entry, residual forage at exit, and any observations about pasture condition or animal behavior. These records allow you to calculate actual stocking rates and compare them across seasons and years.

Keep a flock record that tracks body condition scores, weights, and health events for each sheep or group. This information helps you identify whether nutrition problems are affecting specific classes of animals. It also provides data for adjusting stocking rates in future years.

Track pasture growth rates by measuring forage mass at regular intervals in rested paddocks. This data helps you predict when pasture will reach grazing height and when you need to slow the rotation or provide supplemental feed.

Using Records to Adjust Stocking Rates

Review your grazing records at the end of each season. Calculate the actual stocking rate for each paddock by dividing the number of sheep-days by the paddock area. Compare actual stocking rates to your planned rates and to pasture condition outcomes. If pasture condition declined, reduce stocking rate next year. If pasture was underutilized, consider increasing stocking rate or adjusting the rotation schedule.

Records also help you identify patterns. If residuals are consistently low in late summer, plan for supplemental feed or reduce stocking rate before that period next year. If body condition scores decline at a specific production stage, adjust nutrition or stocking to address the cause.

Common Failure Patterns in Stocking Rate Management

Overstocking During Drought

Drought reduces pasture growth faster than most farmers expect. By the time pasture looks short, root reserves are already depleted and recovery will be slow. The failure pattern is waiting too long to reduce stocking rate or provide supplemental feed. Monitor pasture growth and soil moisture regularly, and have a drought plan that includes destocking triggers based on measured forage supply, not visual appearance.

Understocking in Spring

Spring pasture growth often exceeds what the flock can consume, especially in rotational systems with long rest periods. The failure pattern is leaving too much residual, which allows pasture to mature and decline in quality. Sheep eat the most nutritious parts of mature plants and leave the stems, reducing overall forage quality. Adjust the rotation to move sheep faster through spring growth, or add animals to utilize the surplus.

Ignoring Parasite Buildup

High stocking rates concentrate manure and parasite larvae on pasture. The failure pattern is keeping sheep on contaminated pasture too long because the forage looks adequate. The rotational grazing parasite study showed that moving sheep to new pasture when grass height fell below 10 centimeters, combined with veterinary monitoring, maintained acceptable parasite levels. Monitor fecal egg counts and use pasture moves as a parasite management tool, beyond a forage management tool.

Failing to Adjust for Sheep Class

Stocking rate calculations based on mature ewe equivalents do not account for the different forage demands of lambs, yearlings, and rams. The failure pattern is running more animals than the pasture supports because the calculation did not include the higher intake of growing or lactating animals. Use metabolic weight to standardize across classes and recalculate whenever flock composition changes.

Limitations of Stocking Rate Calculations

Variability in Pasture Growth

Stocking rate calculations are based on current forage supply and expected growth rates. Both are variable. Rainfall, temperature, and soil conditions change pasture growth from week to week and year to year. A stocking rate that works in an average year may be too high in a dry year and too low in a wet year. Recalculate stocking rates regularly and adjust based on current conditions.

Measurement Error

Forage estimation methods have inherent error. Clipped samples are accurate for the sampled area but may not represent the whole paddock. Rising plate meters and pasture sticks are calibrated to specific pasture types and lose accuracy when pasture composition changes. Visual estimation is the least accurate method. Use multiple methods and cross-check your measurements to reduce error.

Regional Differences

Stocking rate recommendations from other regions may not apply to your farm. Soil type, rainfall patterns, pasture species, and management history all affect pasture productivity. The Food and Agriculture Organization of the United Nations provides international guidance on animal production that emphasizes local adaptation. Use published recommendations as starting points, then adjust based on your own measurements and observations.

Welfare and Safety Context for Grazing Management

Animal Welfare Considerations

Stocking rate directly affects sheep welfare. Overstocked sheep compete for limited forage, lose body condition, and experience increased stress. Understocked sheep may become overconditioned, which creates problems at lambing and reduces fertility. The World Organisation for Animal Health sets international standards for animal health and welfare that include provisions for adequate nutrition and living conditions.

Monitor sheep behavior as an indicator of welfare. Sheep that are constantly grazing with no rest periods may be struggling to meet their intake needs. Sheep that are lying down and ruminating for extended periods are likely getting adequate nutrition. Changes in grazing behavior can indicate problems with forage quality, parasite burdens, or social dynamics within the flock.

Worker Safety in Grazing Systems

Moving sheep between paddocks involves physical labor, fencing work, and interaction with livestock. Use proper handling techniques to avoid injury from sheep pushing or kicking. When moving portable fencing, be aware of the risk of trips and falls on uneven ground. When working with virtual fencing systems, follow the manufacturer's safety instructions for handling collars and charging equipment.

The U.S. Food and Drug Administration provides resources on animal veterinary topics, including the safe use of animal health products. If you use anthelmintics or other veterinary products as part of your parasite management program, follow label instructions and observe withdrawal periods where applicable.

Food Safety Considerations

If you sell sheep or lamb for meat, grazing management affects food safety through its influence on animal health and the need for veterinary treatments. The U.S. Food and Drug Administration regulates animal drugs and feed additives, including withdrawal periods that ensure residues do not remain in meat. Keep accurate treatment records and observe all withdrawal periods. Rotational grazing that reduces parasite burdens may reduce the need for anthelmintic treatments, which can simplify residue management.

Professional Escalation Criteria

When to Consult a Veterinarian

Contact your veterinarian if body condition scores decline despite adequate forage supply, if fecal egg counts remain high after pasture moves, or if multiple sheep show signs of ill health such as diarrhea, weight loss, or reduced appetite. The rotational grazing parasite study demonstrated that veterinary monitoring is essential for non-chemical parasite management strategies. Your veterinarian can help you interpret fecal egg count results, diagnose health problems, and develop treatment protocols that fit your grazing system.

When to Consult a Pasture or Forage Specialist

Contact a pasture or forage specialist if you are unsure how to measure forage supply, if pasture composition is shifting toward undesirable species, or if you need help designing a rotational grazing system. Specialists can help you identify pasture species, assess soil fertility, and develop a grazing plan that matches your forage resources. The USDA Agricultural Research Service conducts research on animal production systems that can inform grazing management decisions.

When to Consult an Agricultural Adviser

Contact an agricultural adviser or extension agent if you are making major changes to your grazing system, such as converting from continuous to rotational grazing, adopting adaptive multi-paddock grazing, or investing in virtual fencing infrastructure. Advisers can help you assess the economic implications of system changes and develop implementation plans. The Australian sheep farm study found persistent trade-offs between economic and environmental outcomes in grazing systems, so professional advice can help you clarify your objectives and choose a system that matches them.

Frequently Asked Questions

How many sheep can I keep per acre?

The number of sheep per acre depends on pasture productivity, rainfall, soil type, and sheep class. A typical range is 2 to 4 mature ewes per acre under continuous grazing and 4 to 8 mature ewes per acre under rotational grazing, but these are starting points. Measure your pasture forage supply and calculate stocking rate using the worksheet in this article. Adjust based on observed pasture residuals and sheep body condition.

What is the best rotational grazing plan for sheep?

The best plan matches your pasture rest period and grazing period to your paddock layout. Divide the rest period by the grazing period to get the minimum number of paddocks. For a 30 day rest period and a 3 day grazing period, you need at least 10 paddocks. Monitor pasture regrowth and adjust the rotation schedule based on growth rates. The rotational grazing parasite study used a simple rule of moving sheep to new pasture when grass height fell below 10 centimeters, combined with quarterly veterinary monitoring.

How do I calculate stocking rate for my pasture?

Measure available forage in pounds of dry matter per acre, multiply by the grazeable area and utilization rate to get total available forage, then divide by sheep daily intake multiplied by grazing days. Use metabolic body weight to standardize across sheep classes. Build in a 15 to 20 percent safety margin for variable pasture growth.

What is the difference between stocking rate and stocking density?

Stocking rate is the number of animals per unit area over a defined grazing period, such as ewes per acre for the grazing season. Stocking density is the number of animals per unit area at a specific point in time, such as ewes per acre in a single paddock during a 3 day grazing period. Rotational grazing uses high stocking density for short periods, while continuous grazing uses low stocking density for the entire season.

How does rotational grazing affect parasite control in sheep?

Rotational grazing can reduce parasite burdens by moving sheep away from contaminated pasture before they ingest large numbers of larvae. The rotational grazing parasite study found that sheep managed with rotational grazing and veterinary monitoring maintained acceptable parasite levels and higher body condition scores than sheep receiving routine anthelmintic treatment, despite having higher fecal egg counts. Monitor fecal egg counts and work with your veterinarian to determine if rotational grazing can reduce your reliance on chemical treatments.

What pasture residual should I leave after grazing sheep?

Leave 1,000 to 1,200 pounds of dry matter per acre as residual for cool-season grasses. This protects plant regrowth and soil. Leaving too much residual wastes forage and allows pasture to mature. Leaving too little damages plants and reduces future production. Measure residuals after each grazing event and adjust stocking rate or grazing period to achieve consistent residuals.

How does sheep grazing affect biodiversity?

Sheep grazing can support biodiversity when managed appropriately. A study of sheep-grazed pastures in Austria found that small aerial insectivores showed significantly higher activity in grazed and post-grazed pastures compared to pre-grazed pastures, and one bat species was significantly more active in post-grazed pastures. The study, published as Do sheep-grazed pastures support insectivorous bat activity and bat species richness, noted that comparisons with cattle grazing should be cautious because cattle studies often span longer timeframes on larger, higher-biomass pastures. Grazing management context matters for biodiversity outcomes.

When should I reduce my stocking rate?

Reduce stocking rate when pasture residuals are consistently below target, when body condition scores decline, when pasture growth slows due to drought or cold, or when fecal egg counts indicate high parasite burdens. Have predetermined triggers for destocking based on measured forage supply and animal condition. The Australian sheep farm study found that whole-farm stocking rate and rainfall strongly influenced pasture production and profit, so adjusting stocking rate to current conditions is essential for both economic and environmental outcomes.
