Sheep Ranch Management: From Land to Flock

Sheep ranch management connects land stewardship, infrastructure, and flock health into one operating system. For farmers, farm employees, veterinarians, advisers, students, and farm planners, the practical question is how to make daily decisions that keep pasture productive, facilities functional, and sheep healthy across changing seasons. This article outlines the core management areas, the records that support decisions, and the warning signs that require professional help. The focus is on practical action, not theory.

At a Glance: Core Management Areas

Land and Pasture Management

Pasture is the foundation of sheep ranch management. The forage available on your land determines how many sheep you can carry, how much supplemental feed you need, and how healthy your flock remains. Management practices can substantially influence animal performance and health, and these practices remain poorly documented in many sheep breeds, which means individual ranchers must build their own reliable records instead of rely on industry averages. A producer survey of flocks enrolled in the National Sheep Improvement Program found that management practices vary widely across breeds and regions, reflecting distinct production goals, geographies, climatic pressures, and historical selection priorities. This variation means there is no single correct pasture system, only systems that fit your land and your records.

Grazing Systems and Stocking Rates

The first decision is how many sheep your land can support. Stocking rate depends on forage production, which varies with rainfall, soil type, and plant community. A conservative starting point is to stock at a rate that leaves adequate residual forage after grazing. Overstocking leads to bare soil, weed invasion, and reduced regrowth, while understocking wastes forage and can reduce pasture quality as plants mature.

Rotational grazing divides the ranch into paddocks and moves sheep through them on a schedule. The rest period between grazings is as important as the grazing period itself. Forage needs time to regrow before sheep return. A common failure is returning sheep to a paddock too soon, which weakens plants and reduces long-term production. Forage-livestock balance models, such as those applied to household ranches in grassland regions, show that optimizing the match between forage supply and animal demand requires adjusting stocking rates and grazing schedules to local conditions. The practical implication is that your grazing plan must be reviewed at least seasonally and adjusted when forage growth differs from expectations.

Forage Testing and Supplementation

Forage quality changes through the season. Young vegetative growth is high in protein and energy, while mature plants are higher in fiber and lower in digestibility. Testing pasture and hay tells you what nutrients sheep are actually getting. This matters most in late pregnancy and early lactation, when ewes have the highest nutritional demands.

Supplementation decisions should follow test results, not guesses. If forage protein is low, a protein supplement may be needed. If energy is low, grain or other energy-dense feeds may be required. The cost of testing is small compared to the cost of underfeeding or overfeeding. Records of forage test results over several years help you predict when quality will drop on your ranch and plan supplementation accordingly.

Water Management

Water is the most critical nutrient. Sheep need clean, accessible water at all times. Water sources include wells, springs, ponds, and troughs. Each source has management requirements. Wells need regular testing for water quality. Springs need protection from contamination. Ponds need fencing to prevent bank damage and water pollution. Troughs need cleaning and flow checks.

Historical sheep ranch handbooks from the late 19th century already emphasized water management as a core ranch responsibility, and the principle remains unchanged. The practical standard is that every paddock must have a reliable water source, and water flow must be checked during hot weather when consumption rises. A ewe with lambs can drink several gallons per day in summer, and inadequate water reduces milk production and lamb growth.

Facilities and Infrastructure

Facilities support every other management activity. Good infrastructure makes handling, treatment, and lambing safer for both sheep and people. Poor infrastructure creates stress, increases labor, and leads to injuries.

Fencing and Handling Systems

Perimeter fencing keeps sheep in and predators out. Interior fencing divides pastures for rotational grazing. Both must be maintained. A broken fence line is beyond an inconvenience, it is a biosecurity and safety risk. Sheep that escape can be injured, lost, or exposed to disease.

Handling systems should be designed for low-stress movement. A well-designed system includes a gathering pen, a forcing pen, a race or alley, and a sorting gate. The race should be wide enough for sheep to move freely but narrow enough to prevent turning around. Solid sides reduce visual distraction and keep sheep calm. The handling area should have good footing to prevent slips and falls, which are a common cause of injury to both sheep and handlers.

Lambing Facilities

Lambing facilities need to provide shelter from weather, space for ewes to bond with lambs, and a clean environment to reduce disease. The design depends on your lambing season and climate. Indoor lambing requires pens that can be cleaned and disinfected between uses. Outdoor lambing requires windbreaks and dry ground.

Lambing season affects mother-young relationships and lamb vigor. Research on D'man sheep found that birth weight was lower for summer and winter born lambs, and that ewes provided higher intensity of care to their offspring in winter, with shorter latency for grooming and longer time spent grooming compared to spring and summer lambing. Lambs were most active in spring, faster to extend their hind legs, stand up, and reach the udder. Rectal temperature at 48 hours was affected by season of birth, with higher values observed in summer. These findings show that lambing facilities must be matched to the season. Winter lambing requires more shelter and closer supervision. Spring lambing allows more outdoor activity but still requires protection from cold snaps.

Biosecurity Infrastructure

Biosecurity is a management system, not a single action. Infrastructure supports biosecurity by separating new animals from the resident flock, controlling visitor access, and managing carcass disposal. A pilot study of small ruminant farms in Kosovo after an outbreak of peste des petits ruminants found that external biosecurity scores, which prevent pathogen introduction, were higher than internal biosecurity scores, which limit spread within farms. The lowest external scores were for transport and carcass removal and infrastructure, while disease management scored lowest for internal biosecurity. This pattern is common. Ranchers often focus on preventing disease entry but neglect the practices that stop disease spread once it is inside.

Practical biosecurity infrastructure includes a quarantine area for new animals, a footbath or boot change station at the entrance to sheep areas, separate equipment for sick animals, and a designated area for carcass disposal that is inaccessible to dogs and wildlife. The quarantine area should be far enough from the main flock to prevent aerosol or contact transmission, and it should be used for at least the period recommended by your veterinarian.

Flock Health Management

Flock health is the result of nutrition, biosecurity, parasite control, and timely treatment. The goal is to prevent disease, detect problems early, and treat effectively when treatment is needed.

Parasite Control

Gastrointestinal nematodes are a major limit to small ruminant production in many regions, causing economic losses and reduced productivity. Control depends heavily on anthelmintic drugs, but intensive and improper use has accelerated the development of anthelmintic resistance. A review of gastrointestinal nematodes in small ruminants in Southern Africa found that macrocyclic lactone resistance, particularly to ivermectin, was most prevalent, with significantly more farms harboring resistant parasite populations than susceptible ones. Haemonchus was the dominant resistant genus, with 62.2 percent of farms reporting resistant populations. Lower resistance levels were observed in Teladorsagia, Trichostrongylus, Oesophagostomum, and Cooperia species. The underlying reasons for resistance are likely driven by frequent whole-flock treatments, improper dosing, limited drug rotation, and reduced refugia.

The practical response is to treat selectively, not routinely. Fecal egg counts tell you which animals need treatment and when. Treating only the animals with high egg counts preserves susceptible parasites in the flock, which dilutes resistant populations. This approach, called targeted selective treatment, reduces drug use and slows resistance development. Your veterinarian can help you set up a fecal egg count monitoring program and interpret the results.

Seasonal patterns matter. A survey in the Gwalior region of India found that gastrointestinal parasitism in sheep and goats was influenced by inappropriate care, unhygienic environmental conditions, severe and hot climatic conditions, and close interaction with other infected animals. The incidence of Haemonchus in sheep was 58.1 percent, Coccidia 37.2 percent, and Trichuris 23.2 percent. These numbers show that parasites are present in most flocks and that monitoring must be regular, not occasional.

Vaccination and Treatment Protocols

Vaccination programs should be designed with your veterinarian based on the diseases present in your area. Common vaccines protect against clostridial diseases, which cause sudden death, and other region-specific diseases. Treatment protocols should follow veterinary guidance, and all treatments must be recorded with the product used, the dose, the route, the date, and the withdrawal period.

The U.S. Food and Drug Administration provides animal and veterinary resources that cover the approved use of animal drugs, including withdrawal periods and residue avoidance. The World Organisation for Animal Health provides international standards for animal health and welfare that inform national programs. The USDA National Agricultural Library maintains resources on animal health and welfare that support producer education. These official sources are the appropriate references for treatment decisions, not anecdotal advice from other producers.

Disease Surveillance and Reporting

Some diseases are reportable, meaning that suspicion or confirmation must be reported to animal health authorities. Sheep and goat pox is a Category A epizootic disease that caused a major outbreak in Greece from 2024 to 2025, with 1905 farms confirmed positive across more than a dozen regional units. The outbreak trajectory was influenced by strategic behavior, limits on administrative capacity, and fractured trust between producers and the state. The analysis of this outbreak concluded that disease governance must address also epidemiological factors but also the incentives that drive reporting and movement compliance.

The lesson for ranchers is that disease reporting is a collective responsibility. Hiding disease or delaying reporting allows spread to neighboring flocks and prolongs the outbreak. The practical standard is to know the reportable diseases in your region, recognize their signs, and report suspicious cases immediately to your veterinarian or animal health authority.

Zoonotic Disease Awareness

Several sheep diseases can infect humans. Q fever, caused by Coxiella burnetii, is among the most highly infectious zoonotic pathogens transmitted among livestock. A study in Laikipia County, Kenya, found that seroprevalence varied across livestock species and management systems, with sheep at 13 percent, goats at 18 percent, camels at 20 percent, and cattle at 6 percent. Animals from mixed conservancy and commercial operations and smallholder operations had higher odds of testing seropositive compared to animals from agro-commercial ranches. Young animals had lower odds of testing seropositive than adults, and males had lower odds than females.

The practical implications are that pregnant women, people with heart valve disease, and immunocompromised individuals should avoid contact with lambing ewes and placental material. Workers should wear gloves when handling afterbirth and aborted fetuses. Abortion storms in sheep should always raise suspicion of Q fever and prompt veterinary investigation.

Breeding and Lambing Management

Breeding decisions determine the genetic direction of the flock and the timing of the production cycle. Lambing management determines how many lambs survive to weaning.

Ram Selection and Breeding Season

Ram selection should focus on traits that improve flock productivity, including growth rate, carcass quality, and maternal traits. Genetic evaluation programs provide data on these traits. A study of Horro sheep under smallholder farm management in Ethiopia estimated heritability of 0.16 for birth weight, 0.19 for three-month weight, and 0.28 for six-month weight. The moderate heritability estimates indicate that genetic improvement through selection could lead to meaningful genetic change. The practical implication is that selecting rams from flocks with recorded performance data is more effective than selecting on visual appraisal alone.

Breeding season timing determines lambing season timing. Sheep are seasonal breeders, but some breeds can mate and give birth year-round. The choice of lambing season affects labor needs, feed costs, and lamb prices. Winter lambing requires more shelter and feed but may capture higher market prices. Spring lambing reduces feed costs but may face lower prices. The decision should be based on your facilities, labor, and market.

Lambing Supervision and Neonatal Care

Lamb survival in the first 28 days of life is critical because it increases the chances of economic gain in the flock. A study of Magra and Marwari sheep in the arid region of India found that neonatal mortality was very low in both breeds, at 1.04 percent for Magra and 2.48 percent for Marwari, under a semi-intensive management system. Males had lower odds of survival than females. Odds of survival were low for lambs born to dams of low body weight and in their first parity. Lamb survival could be improved with due care of lambs born with low birth weight, below 2 kilograms. The heritability estimate was moderate in Magra sheep at 0.17, indicating scope for genetic improvement for lamb survival through selection.

The practical lessons are that first-parity ewes and low-birth-weight lambs need extra attention, and that lamb survival is influenced by both genetics and management. A lambing calendar that assigns supervision priorities based on ewe parity and expected birth weight helps focus labor where it matters most.

Culling Decisions

Culling is the removal of animals from the flock for reasons including age, poor production, health problems, and behavior. Culling decisions shape the genetic direction of the flock and its economic performance. A survey of producers in the National Sheep Improvement Program found that the reasons ewes were culled varied by breed. Udder health problems were ranked as the primary culling reason for Katahdin, Polypay, and Suffolk producers, while fine-wool producers most often cited age as their primary culling reason. Ram lamb castration practices also differed by breed, with over 90 percent of Katahdin producers not routinely castrating ram lambs.

The practical implication is that culling criteria should be written down and applied consistently. Udder health is a major reason for culling in many breeds, so udder scoring at weaning and before breeding helps identify ewes that should not be retained. Age-based culling keeps the flock young and productive but must be balanced against the cost of replacements.

Nutrition and Feeding Management

Nutrition drives reproduction, growth, milk production, and health. The nutritional program must match the stage of production, with the highest demands in late pregnancy and early lactation.

Body Condition Scoring

Body condition scoring is a hands-on assessment of the fat and muscle cover over the spine and loin. The scale typically runs from 1 to 5, with 1 being emaciated and 5 being obese. Body condition should be assessed at key points in the production cycle, including before breeding, at pregnancy diagnosis, in late pregnancy, and at weaning.

The target body condition score depends on the stage of production. Ewes should be in moderate condition at breeding, gaining condition in late pregnancy, and losing some condition in early lactation. Ewes that are too thin at breeding have lower conception rates. Ewes that are too fat at lambing have higher rates of pregnancy toxemia and lambing difficulty.

Feed Budgeting

A feed budget matches feed supply to animal demand across the year. The budget starts with an inventory of available forage, including pasture, hay, and silage. The demand side is calculated from the number of animals, their weights, and their stage of production. The difference between supply and demand determines how much supplemental feed is needed and when.

Feed budgeting is especially important in arid and semi-arid regions where forage production is variable. A study of pastoral farming systems in southern Tunisia identified three distinct systems, including small urban farmers with small-scale operations relying on family labor and localized feed resources, large professionalized operations with improved infrastructure and hired labor using transhumance to optimize resource use, and herds with camels using extensive systems with collective rangelands. The study emphasized how ecological constraints, infrastructure, and spatial organization shape the diversity of these systems. The practical lesson is that feed budgeting must account for local variability and include contingency plans for drought years.

Nutritional Impacts on Health

Nutrition affects disease resistance. Sheep that are undernourished have weaker immune responses and are more susceptible to parasites and other infections. Overfeeding can also cause problems, including pregnancy toxemia in ewes carrying multiple lambs and urinary calculi in wethers.

The interaction between nutrition and disease is complex. A study of Trypanosoma evansi in the Brazilian Pantanal found that infection was detected in all species sampled except sheep and feral pigs, and that the relationship between ranch management and infection in horses was investigated. While this study did not find infection in sheep, it illustrates that disease patterns vary by species and management system. The practical implication is that nutrition and disease management must be considered together, not separately.

Records and Financial Management

Records are the foundation of good management decisions. Without records, you cannot know which ewes are productive, which treatments are working, or whether the ranch is profitable.

Production Records

Production records include individual animal identification, birth dates, birth weights, weaning weights, lambing ease scores, and culling reasons. These records support genetic evaluation and culling decisions. The National Sheep Improvement Program represents an important segment of the U.S. sheep industry engaged in data-oriented genetic improvement, and its producer survey found that management practices vary widely across breeds. The practical implication is that producers enrolled in genetic evaluation programs need accurate production records to benefit from the program.

Individual identification of sheep is essential for record keeping. Traditional methods such as ear tags and tattoos are labor-intensive but effective. Newer methods, including facial recognition technology, are being developed. A study proposed an Attention Residual Module to improve the accuracy of convolutional neural networks for sheep face recognition, with accuracy improvements of 10.2 percent for VGG16, 6.65 percent for GoogLeNet, and 4.38 percent for ResNet50 compared to networks without the module. While facial recognition is not yet practical for most ranches, it points to a future where individual identification is less labor-intensive.

Financial Records

Financial management is a critical component in the long-term viability of ranches and farms. Proper and timely financial reporting and analysis of financial statements are valuable tools that agricultural producers can use to monitor, coordinate, and plan their operational production and marketing schemes and strategies. Agricultural producers are responsible for preparing their own financial statements, and lending institutions may prepare their own statements in their assessment of the financial condition of a business. The responsibility of financial statements is the borrower's.

Standard Performance Analysis techniques and associated software have been developed for cow-calf, stocker, seedstock, and sheep enterprises. Critical to the analysis is having complete and correct financial statements. Proper financial reporting is critical also to a Standard Performance Analysis assessment but also to the overall financial management of farms and ranches. Taking a proactive stance in one's financial plan is paramount to success.

The practical implication is that financial records must be kept current and complete. Income statements show profitability, balance sheets show financial position, and cash flow statements show liquidity. These statements should be reviewed at least quarterly, and production records should be linked to financial records so you know which enterprises are profitable.

Records for Biosecurity and Treatment

Treatment records must include the date, the animal or group treated, the product used, the dose, the route of administration, and the withdrawal period. These records are required for food safety and are essential for detecting treatment failures. If a treatment does not work, the record helps you and your veterinarian determine whether the problem is resistance, incorrect dosing, or misdiagnosis.

Biosecurity records include animal movements on and off the ranch, visitor logs, and quarantine records. These records support disease investigation if an outbreak occurs. The Food and Drug Administration provides animal and veterinary resources that cover the approved use of animal drugs and residue avoidance, and these resources support the record-keeping requirements for food-producing animals.

Seasonal Management Calendar

A seasonal management calendar organizes tasks by time of year and helps ensure that nothing is missed. The calendar should be adapted to your specific ranch, climate, and production system.

Spring

Spring is the peak of lambing for many ranches. Tasks include lambing supervision, neonatal care, and early pasture management. Lambs need colostrum within the first hours of life, and weak lambs may need assistance nursing. Pasture growth accelerates as temperatures rise, and grazing rotations should be adjusted to match forage growth.

Spring is also the time for the first fecal egg counts of the year. Parasite eggs begin to appear as temperatures warm, and early detection allows targeted treatment before contamination builds up on pasture.

Summer

Summer brings heat stress and parasite pressure. Water consumption rises, and water sources must be checked frequently. Pasture quality declines as plants mature, and supplemental feeding may be needed if forage quality drops below the requirements of lactating ewes.

Summer is the time for weaning. Weaning reduces the nutritional demand on ewes and allows them to regain condition before the next breeding season. Weaning also provides an opportunity to assess udder health and make culling decisions.

Autumn

Autumn is the breeding season for many flocks. Ewes should be in moderate to good condition at breeding, and rams should be examined for soundness before turnout. Pregnancy diagnosis, typically by ultrasound, can be performed a few weeks after breeding to identify open ewes.

Autumn is also the time for internal parasite control before the winter. Fecal egg counts guide treatment decisions, and pasture management can reduce the carryover of parasite larvae into the next grazing season.

Winter

Winter is the period of highest nutritional demand for pregnant ewes. Late pregnancy is the most critical time for nutrition, and ewes carrying multiple lambs need higher energy intake. Pregnancy toxemia is a risk for ewes that are overfat or underfed in late pregnancy.

Winter is also the time for facility maintenance. Fences, water systems, and handling equipment should be repaired before the next lambing season. Feed inventories should be reviewed to ensure adequate supply through the winter.

Common Failure Patterns

Understanding common failure patterns helps you avoid them. These patterns appear across ranches and regions, and recognizing them early prevents larger problems.

Overstocking

Overstocking is the most common pasture management failure. It occurs when the number of animals exceeds the carrying capacity of the land. The signs are bare soil, reduced forage regrowth, weed invasion, and poor animal condition. Overstocking is often driven by economic pressure to maximize animal numbers, but it reduces long-term productivity and increases feed costs.

Routine Whole-Flock Deworming

Routine whole-flock deworming is a common parasite management failure. It accelerates anthelmintic resistance by removing susceptible parasites and leaving only resistant ones to reproduce. The alternative is targeted selective treatment based on fecal egg counts, which preserves susceptible parasites in refugia and slows resistance development.

Incomplete Records

Incomplete records are a common management failure. Without records, you cannot identify productive animals, track treatment effectiveness, or assess profitability. The solution is to establish a simple record-keeping system and use it consistently. Records do not need to be complex to be useful.

Poor Biosecurity

Poor biosecurity is a common failure that allows disease introduction and spread. The Kosovo study found that external biosecurity scores were higher than internal biosecurity scores, meaning that ranchers focused on preventing disease entry but neglected practices that limit spread within farms. The lowest internal score was for disease management, which includes practices like isolating sick animals and disinfecting equipment.

Ignoring Zoonotic Risks

Ignoring zoonotic risks is a failure that affects human health. Q fever is a serious zoonotic disease that can be transmitted from sheep to humans, particularly during lambing. Workers should be educated about the risks and provided with appropriate protective equipment.

Welfare and Safety Context

Sheep welfare is both an ethical responsibility and a management factor. Poor welfare reduces productivity and increases disease susceptibility. Good welfare is supported by adequate nutrition, clean water, shelter from extreme weather, prompt treatment of injury and disease, and handling practices that minimize stress.

The World Organisation for Animal Health provides international standards for animal health and welfare that inform national programs and producer practices. The USDA Agricultural Research Service conducts research on animal production and protection that supports the development of improved management practices. The Food and Agriculture Organization of the United Nations provides resources on animal production that support sustainable livestock systems.

Worker safety is equally important. Handling sheep involves risks of injury from kicks, crushing, and lifting. Facilities should be designed to minimize these risks, and workers should be trained in safe handling techniques. Zoonotic disease risks should be communicated clearly, and protective equipment should be provided where needed.

Professional Escalation Criteria

Some situations require professional help. The following criteria indicate when to call your veterinarian or other animal health professional.

Veterinary Consultation

Call your veterinarian when you observe signs of disease that do not respond to treatment, when multiple animals become sick at the same time, when you suspect a reportable disease, or when you need help interpreting diagnostic tests. Your veterinarian can also help you design vaccination programs, parasite control programs, and biosecurity protocols.

Diagnostic Testing

Fecal egg counts, blood tests, and postmortem examinations are diagnostic tools that require professional interpretation. If you suspect anthelmintic resistance, a fecal egg count reduction test can confirm it. If you suspect a nutritional problem, blood tests can identify deficiencies. If you have unexplained deaths, a postmortem examination can determine the cause.

Regulatory Reporting

Some diseases are reportable to animal health authorities. The World Organisation for Animal Health provides international standards for disease reporting, and national authorities have specific requirements. If you suspect a reportable disease, contact your veterinarian or animal health authority immediately. Delayed reporting allows disease spread and prolongs outbreaks.

Financial Analysis

If your ranch is not profitable, a financial analysis can identify the problem areas. Standard Performance Analysis techniques provide benchmarks for production and financial performance. A financial adviser or extension specialist can help you interpret your financial statements and develop a plan for improvement.

Frequently Asked Questions

What is the most important factor in sheep ranch management?

The most important factor is matching animal numbers to available forage and water. Overstocking is the most common failure pattern and it drives most other problems, including poor animal condition, parasite buildup, and pasture degradation. A conservative stocking rate with adequate rest periods for pasture is the foundation of sustainable management.

How often should I deworm my sheep?

Deworming frequency should be based on fecal egg counts, not a fixed schedule. Routine whole-flock deworming accelerates anthelmintic resistance, which is a growing problem in many regions. Targeted selective treatment, where only animals with high egg counts are treated, preserves susceptible parasites and slows resistance development. Work with your veterinarian to establish a monitoring program.

What records should I keep for my sheep ranch?

Keep production records including individual animal identification, birth dates, birth weights, weaning weights, lambing ease scores, and culling reasons. Keep treatment records including the product, dose, route, date, and withdrawal period. Keep financial records including income statements, balance sheets, and cash flow statements. Keep biosecurity records including animal movements and visitor logs.

How do I know if my pasture is overstocked?

Signs of overstocking include bare soil, reduced forage regrowth, weed invasion, and poor animal condition. The most reliable method is to monitor forage height and residual biomass after grazing. If forage is consistently grazed to the ground, reduce stocking rates or lengthen rest periods.

What is anthelmintic resistance and how do I prevent it?

Anthelmintic resistance occurs when parasites survive treatment and pass resistant genes to the next generation. It is driven by frequent whole-flock treatments, improper dosing, limited drug rotation, and reduced refugia. Prevention includes targeted selective treatment based on fecal egg counts, correct dosing by weight, and preserving susceptible parasites in refugia.

What zoonotic diseases can I get from sheep?

Q fever, caused by Coxiella burnetii, is among the most highly infectious zoonotic pathogens transmitted among livestock. Other zoonotic diseases include orf, ringworm, and leptospirosis. Pregnant women, people with heart valve disease, and immunocompromised individuals should avoid contact with lambing ewes and placental material.

When should I call my veterinarian?

Call your veterinarian when you observe signs of disease that do not respond to treatment, when multiple animals become sick at the same time, when you suspect a reportable disease, or when you need help interpreting diagnostic tests. Your veterinarian can also help you design vaccination programs, parasite control programs, and biosecurity protocols.

How do I decide which ewes to cull?

Culling decisions should be based on written criteria applied consistently. Common reasons include udder health problems, age, poor production, and reproductive failure. Udder health is a major reason for culling in many breeds, so udder scoring at weaning and before breeding helps identify ewes that should not be retained.
