# Beef Cattle Feedlot Pen Management


## Key Takeaways

- Pen condition directly impacts animal health and performance; inadequate drainage leads to mud, increasing lameness and respiratory disease risk, while proper slope and surface material are crucial for dryness.
- Bunk space allocation and feed delivery timing are critical for mitigating acidosis and ensuring uniform feed intake; restricted space increases competition and the risk of digestive disturbances.
- Daily, systematic observation of cattle for signs of illness (e.g., depression, nasal discharge, lameness) is the primary method for early detection of respiratory disease, digestive upset, and injury, enabling prompt intervention.
- Comprehensive record-keeping of morbidity and mortality, including necropsy findings and cause classification, is essential for identifying health patterns, evaluating management effectiveness, and complying with regulations.
- Weather adaptation strategies, such as providing windbreaks, shade, and managing mud or bedding, are vital for mitigating heat stress and preventing disease, as mortality spikes often coincide with environmental extremes.
- Water supply management, including flow rate, trough placement, cleaning frequency, and temperature control, is inseparable from pen conditions and directly influences feed intake and overall health.

---

The primary management objective in beef cattle feedlot pen systems is to maintain an environment that supports health, feed intake, and growth while minimizing disease and mortality. Pen management encompasses the physical condition of the pen, the allocation of bunk space and water, adaptation to weather, daily observation of cattle, and systematic record keeping of morbidity and mortality. These factors are interdependent: inadequate drainage undermines hoof health, restricted bunk space increases competition and risk of acidosis, and poor observation delays intervention for sick animals. Management decisions must be based on facility design, stocking density, and the nutritional stage of the cattle, with no single approach applicable to all operations.

## System Context and Planning Decisions

## [Feedlot Design](/knowledge/animal-farming/farm-management/beef-cattle-feedlot-design-pen-layout-manure) and Capacity

Pen management begins at the design stage. The feedlot layout must accommodate the expected number of cattle and the anticipated duration of the feeding period. Factors such as orientation to prevailing winds, proximity to feed storage and processing areas, and access for delivery trucks and veterinary vehicles influence daily management. The FAO Animal Production and Health guidelines emphasize that pen surface slope, drainage patterns, and base material determine the ability to keep cattle dry and clean. Concrete aprons along the feed bunk reduce mud accumulation and improve footing, while soil-based pens require regular reshaping to maintain surface drainage.

### Stocking Density and Pen Dimensions

Space allocation per animal affects both performance and health. Overcrowding reduces bunk space and increases social stress, leading to variation in feed intake and higher risk of digestive disturbances. The USDA National Animal Health Monitoring System reports indicate that common space allowances range from 20 to 50 square meters per animal depending on expected final weight, climate, and pen surface type. Stocking density must be adjusted seasonally: wet conditions demand more space to prevent mud accumulation, while dry lots can sustain higher densities with proper management. Pen shape also matters, long, narrow pens allow more linear bunk space per head.

## Core Management Framework

### Morbidity and Mortality Monitoring

Daily observation is the foundation of feedlot pen management. Personnel must walk pens systematically, observing each animal for signs of illness including depression, nasal discharge, coughing, lameness, and reduced feed intake. The Merck Veterinary Manual describes these checks as the primary method for early detection of respiratory disease, digestive upset, and injury. Any animal that fails to come to the bunk, stands apart from the group, or shows abnormal posture should be removed for examination. Morbidity rates are tracked by pen and feeding group, and cumulative data are used to identify patterns linked to management changes, weather events, or feed transitions.

### Record Keeping Standards

Complete records enable analysis of pen-level performance and health outcomes. Mortality records should include the date, ear tag number, estimated body weight, presumptive cause of death, and whether a necropsy was performed. The USDA APHIS Livestock and Poultry Disease resources stress that consistent coding of causes (respiratory, digestive, injury, unknown) allows managers to detect emerging problems early. Records must also document pen cleaning, manure removal, and repairs to fencing, waterers, and feed bunks. These data are essential for compliance with animal health regulations and for continuous improvement of pen management protocols.

Pen condition directly affects cattle performance and health. Well-drained pens with adequate slope prevent mud accumulation, which increases energy expenditure and predisposes animals to lameness and respiratory disease. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) guidelines emphasize that each animal requires at least 30 to 50 cm of linear bunk space depending on body size and feeding system, and one water space per 20 head or sufficient flow to meet peak demand. Water troughs must be cleaned regularly to avoid biofilm and algal growth, which suppress intake. Weather events,especially heat waves or prolonged rain,require proactive pen management: shade or sprinklers during high ambient temperature, and bedding or mound construction during wet periods to provide dry resting areas. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) notes that heat stress is exacerbated by high humidity and lack of airflow, and that mortality spikes often coincide with weather extremes.

Nutrition and water management are inseparable from pen conditions. The transition to high-concentrate diets demands a structured adaptation period, typically lasting 21 to 28 days, during which roughage is gradually reduced. Abrupt introduction of concentrates overwhelms ruminal buffering capacity, leading to subacute or acute acidosis. A review of adaptation strategies (see [Adaptation of beef cattle to high-concentrate diets](https://api.elsevier.com/content/abstract/scopus_id/35349018739)) confirms that step-up programs reduce the incidence of acidosis and improve feed efficiency, but optimal protocols vary by ingredient source, animal type, and environmental stressors. Water quality is equally critical, high sulfate, nitrate, or total dissolved solids reduce intake and predispose cattle to urolithiasis and polioencephalomalacia. Operators should test water sources seasonally and ensure that troughs are located such that cattle do not have to compete for access.

Production-stage decisions must account for animal weight, days on feed, and market endpoint. Early in the feeding period (first 14 days), careful bunk reading is essential to detect shy feeders or animals that are slow to adapt. Mid, and late,stage management focuses on preventing ruminal acidosis and liver abscesses, which reduce carcass yield and grade. [Acidosis in Feedlot Cattle](https://api.elsevier.com/content/abstract/scopus_id/34250851595) describes how repeated bouts of subacute acidosis damage the rumen epithelium and allow translocation of bacteria to the liver, resulting in abscesses. The incidence of dark,cutting beef, a condition of high pH and poor color stability linked to chronic stress before slaughter, is influenced by pen environment, handling practices, and transport (see [Factors Contributing to the Incidence of Dark Cutting Beef](https://api.elsevier.com/content/abstract/scopus_id/0032134838)). Maintaining consistent feeding schedules, minimizing pen changes, and avoiding mixing unfamiliar animals reduce that risk.

Records are the backbone of pen management. Daily observation of feed intake, water consumption, and clinical signs allows early detection of disease outbreaks. Mortality data, recorded by cause (respiratory, digestive, injury, unknown), can be benchmarked against regional values from the [USDA National Animal Health Monitoring System (NAHMS)](https://www.aphis.usda.gov/livestock-poultry-disease/nahms). NAHMS feedlot studies report that bovine respiratory disease (BRD) accounts for the largest proportion of deaths, followed by digestive disorders. Accurate necropsy records, ideally reviewed by a veterinarian, improve diagnostic precision and support targeted vaccination or treatment protocols. A snapshot of practices in Brazil (see [A snapshot of management practices and nutritional recommendations used by feedlot nutritionists in Brazil](https://api.elsevier.com/content/abstract/scopus_id/70349686949)) illustrates that nutritionists rely on feed consumption records to adjust ration energy density, however, degree of uncertainty around optimal adjustment remains high, particularly when weather or health status changes rapidly.

Welfare and worker safety are intertwined with pen design and daily routines. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) sets standards for acceptable handling facilities, including non,slippery floors, sufficient lighting, and restraint devices that minimize distress. Feedlot workers must be trained to recognize compromised animals and to use low,stress handling techniques. [Food safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) aspects involve prevention of pathogen transmission from manure to the environment. Composting feedlot manure reduces coliform populations significantly, but incomplete composting can leave viable bacteria. Research on the fate of coliforms in composted beef cattle manure (see [Fate of coliform bacteria in composted beef cattle feedlot manure](https://api.elsevier.com/content/abstract/scopus_id/0041707904)) indicates that pile temperature, moisture content, and turning frequency determine pathogen die,off, therefore, consistent protocol monitoring is necessary before land application.

Failure patterns in feedlot pen management often arise from cumulative stresses. Respiratory disease outbreaks tend to occur within the first three weeks, when newly arrived cattle are faced with transport stress, novel pathogens, and diet change. Digestive failures,acidosis, bloat, rumenitis,peak during the adaptation period and again if feeding schedules are disrupted. Mortality records should be stratified by pen, arrival group, and days on feed to reveal management gaps. Uncertainty about specific thresholds (e.g., optimal bunk space per head for a given weight group) is common, when published research does not provide a clear cutoff, consultation with an extension veterinarian or feedlot nutritionist is warranted. Professional escalation is indicated when pen,level death loss exceeds two percent, when more than ten percent of animals in a pen show signs of BRD, or when water consumption drops below expected levels without an obvious cause.

Practical monitoring combines structured observation with data recording. Each pen should be checked at least twice daily,once in the early morning and again in the late afternoon,to assess feedbunk scores, water trough function, and animal behavior. Bunk scores (from empty to heavy refusal) help fine,tune ration delivery. Water intake can be approximated by measuring trough volume and refill frequency, any deviation of more than fifteen percent from normal warrants investigation. [Body condition scoring](/knowledge/animal-farming/farm-management/body-condition-scoring-a-tool-for-feed-management) and gait scoring every two weeks during the finishing phase provide welfare indicators that can preempt acute lameness or injury. Records of these observations, when linked to mortality and treatment records, allow trending analysis across feeding cycles. The [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) resources offer guidance on disease surveillance in feedlots, though specific case definitions may vary regionally. Ultimately, pen management requires continuous adjustment based on a combination of empirical data, published evidence, and veterinary input, with the understanding that no single protocol fits all feedlot operations.

## Health Monitoring and Veterinary Care

Daily observation of cattle is the foundation of early disease detection in feedlot pens. Personnel should walk pens at the same time each day, ideally during the coolest part of the morning, and look for animals that are isolated, depressed, or showing abnormal posture and gait. Specific indicators include drooped ears, nasal or ocular discharge, labored breathing, diarrhea, and reduced feed or water intake. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) provides detailed descriptions of clinical signs for respiratory disease, digestive disorders, and lameness that should guide observation protocols. Any animal that does not rise when approached or fails to eat after feed delivery warrants immediate individual assessment.

Biosecurity practices must be integrated into daily pen management to prevent the introduction and spread of infectious agents. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) outlines principles for disease control that apply to feedlot settings, including isolation of new arrivals for a minimum of 21 to 28 days, dedicated equipment per pen or proper disinfection between pens, and restricted movement of personnel and vehicles across the facility. [USDA APHIS](https://www.aphis.usda.gov/livestock-poultry-disease) emphasizes the importance of a written biosecurity plan that addresses cleaning protocols for feed trucks, water troughs, and handling chutes. Manure management also affects biosecurity, research on the [fate of coliform bacteria in composted beef cattle feedlot manure](https://api.elsevier.com/content/abstract/scopus_id/0041707904) indicates that proper composting reduces pathogen load, but incomplete composting can leave viable bacteria that may contaminate clean pens.

Diagnostic procedures and veterinary escalation should follow a structured decision-making process. When an animal shows clinical signs, the first step is to record body temperature, respiratory rate, and heart rate, and to observe any discharge or dung consistency. The [USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms) feedlot studies document that the most common causes of morbidity are bovine respiratory disease complex and digestive disorders such as acidosis and bloat. For respiratory cases, nasopharyngeal swabs and blood samples can confirm the pathogen involved, guiding appropriate antimicrobial selection. The [PubMed record 42072010](https://pubmed.ncbi.nlm.nih.gov/42072010/) discusses the role of ruminal acidosis in feedlot cattle, linking dietary management to reduced disease incidence. If multiple animals in the same pen display similar signs within a short period, the veterinarian should be contacted immediately because this pattern suggests an environmental or feed-related issue instead of isolated cases.

Uncertainty exists in several aspects of feedlot pen management, particularly regarding weather interactions and animal behavior. The [PubMed record 41148701](https://pubmed.ncbi.nlm.nih.gov/41148701/) examines how heat stress and sudden cold events affect feed intake and rumen function, with outcomes that vary by breed, body condition, and prior acclimation. Pen surface condition also influences health, muddy or icy pens increase the risk of lameness and dark cutting beef, as noted in [factors contributing to the incidence of dark cutting beef](https://api.elsevier.com/content/abstract/scopus_id/0032134838). When environmental conditions change rapidly, managers should adjust observation frequency and consider providing additional bedding, windbreaks, or shade. Uncertainty also surrounds the effectiveness of different vaccination protocols, the [PubMed record 40756672](https://pubmed.ncbi.nlm.nih.gov/40756672/) highlights that immune response depends on timing relative to transport and feed transition, yet no single schedule fits all operations. In such cases, consulting with a veterinarian who has expertise in feedlot medicine is essential.

Sustainability in feedlot pen management encompasses economic, environmental, and animal welfare dimensions. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) division promotes practices that reduce the carbon footprint of beef production, such as optimizing feed conversion, minimizing water usage, and capturing methane from manure. Pen design that facilitates rapid drainage and manure collection contributes to lower ammonia emissions and better air quality. Mortality records, discussed in earlier sections, are critical for sustainability audits because they reveal areas for improvement in animal handling and health care. [PubMed record 40642985](https://pubmed.ncbi.nlm.nih.gov/40642985/) addresses the relationship between stocking density and aggressive behavior, showing that overcrowding increases injury rates and reduces growth performance. Maintaining appropriate space per animal,factoring in breed, weight, and climate,reduces stress and improves overall welfare.

The [adaptation of beef cattle to high-concentrate diets](https://api.elsevier.com/content/abstract/scopus_id/35349018739) requires careful step-up programs over two to three weeks to allow ruminal microbial populations to adjust. Failure to adapt correctly leads to acidosis, which can cause laminitis and liver abscesses. The [snapshot of management practices and nutritional recommendations used by feedlot nutritionists in Brazil](https://api.elsevier.com/content/abstract/scopus_id/70349686949) illustrates that even within different production systems, the principles of gradual grain inclusion and consistent feed delivery are universally applied. For pens receiving high-concentrate diets, bunk reading skills are paramount: the amount of feed remaining before the next delivery indicates whether intake is on target. If feed is refused for more than two consecutive days, a veterinary check for subacute acidosis or other health issues is warranted.

When mortality or severe illness occurs, diagnostic necropsy by a veterinarian can identify underlying causes such as infectious disease, metabolic disorder, or management failure. The [PubMed record 40990824](https://pubmed.ncbi.nlm.nih.gov/40990824/) provides evidence that postmortem examination reveals lesions not evident during life, including pulmonary fibrosis or liver abscesses. Recording these findings in a mortality log,along with pen number, date, diet, and weather conditions,creates a data set that informs future management adjustments. Sustainability also involves responsible antibiotic use, the [Acidosis in Feedlot Cattle](https://api.elsevier.com/content/abstract/scopus_id/34250851595) review notes that minimizing digestive disease reduces the need for therapeutic antimicrobials. All treatments must be prescribed by a veterinarian and recorded according to regulatory requirements.

### Frequently Asked Questions

**1. How often should feedlot personnel observe each pen?**
Observations should occur at least twice daily,once during the morning feeding and again in the late afternoon or early evening. More frequent checks are recommended during extreme weather, after diet changes, or when cattle are newly arrived.

**2. What are the earliest signs of respiratory disease in feedlot cattle?**
Early signs include decreased feed intake, isolation from the group, droopy ears, nasal or ocular discharge, and an increased respiratory rate. Taking the animal’s temperature (normal is 100,102°F) helps confirm suspicion.

**3. How do I manage biosecurity between pens?**
Use dedicated boots and equipment for each pen or disinfect between pens. Restrict vehicle movement in muddy conditions, and ensure that feed trucks do not contact pen fencing. New arrivals should be housed in a separate quarantine pen for 21 to 28 days.

**4. What should I do when a dead animal is found in a pen?**
Remove the carcass promptly and record the cause of death if known. Submit a representative sample for diagnostic necropsy, especially if multiple deaths occur in a short period. Contact your veterinarian to rule out reportable diseases.

**5. How can I reduce the risk of dark cutting beef?**
Minimize stress during the final 24 hours before slaughter. Avoid mixing unfamiliar cattle, sudden ration changes, and extreme handling. Ensure that pens provide adequate space and comfortable footing to reduce fighting and bruising.

**6. What is the best way to adjust cattle to a high-concentrate diet?**
Gradually increase the proportion of grain over 14 to 21 days, starting with a ration that is at least 50% roughage. Monitor feed intake daily, if intake drops for more than one day, hold the concentrate level constant until intake recovers.

**7. How do weather conditions affect pen management?**
Heat stress reduces feed intake and increases water demand, provide shade and cool, fresh water. Heavy rain creates muddy pens that heighten lameness risk and pathogen survival. In cold snaps, increase energy density of the ration and provide wind protection.

**8. When should I escalate a health concern to a veterinarian?**
Contact your veterinarian if you observe unusual mortality, multiple animals with the same clinical signs, a lack of response to standard treatments, or any suspicion of a foreign animal disease. Also consult about any change in feed formulation or pen environment that affects health.

**Educational Veterinary Notice**
This information is intended for educational use by animal-health professionals and producers. It does not replace the direct advice of a licensed veterinarian who can evaluate the specific conditions of your feedlot operation. Always consult with your herd veterinarian before implementing new management protocols, especially those involving antimicrobial therapy, dietary changes, or disease control measures. Continuous professional education and access to resources such as [FDA Guidance for Industry #263](https://www.fda.gov/animal-veterinary/guidance-industry/guidance-industry-263-recommendations-drug-ordering-veterinary-feed-directive) on veterinary oversight of medically important antimicrobials is recommended to maintain best practices in [feedlot health management](/knowledge/veterinary-medicine/food-animal-medicine/feedlot-health-management-arrival-protocols-disease-surveillance).


## At a Glance

| Aspect | Key Considerations |
|--------|-------------------|
| Pen Siting | Elevation, prevailing wind direction, access to roads and utilities |
| Drainage | Proper slope, crowned surface, runoff collection and treatment |
| Surface and Base | Compacted clay or improved base, crown to shed water |
| Mound Design | Elevated resting area, sufficient size for all cattle to lie down |
| Feeding Space | Adequate linear bunk space per animal to reduce competition |
| Water Access | Sufficient number of troughs, clean water, freeze protection |
| Stocking Density | Appropriate head per pen to avoid overcrowding and welfare issues |

## Frequently Asked Questions

**1. How much slope should a feedlot pen have?**
Pen surfaces should be graded to provide adequate drainage, typically with a slope that moves water away from feed and water areas. The exact percentage depends on soil type and climate, but the goal is to prevent mud accumulation while maintaining firm footing.

**2. What is the ideal stocking density for a feedlot pen?**
Stocking density is determined by factors such as pen dimensions, mound space, climate, and expected weight gain. The aim is to give each animal enough room to lie down, stand, and move without competition. Overstocking leads to mud, stress, and reduced performance.

**3. How often should pens be cleaned?**
Manure removal frequency depends on stocking density, weather, and bedding use. Most feedlots scrape pens as needed to maintain a dry surface. Wet or poorly drained pens may require more frequent cleaning.

**4. Why is a mound important in a feedlot pen?**
A mound provides a high, dry resting area that encourages lying time and reduces mud exposure. The mound should be wide enough and long enough to accommodate all animals simultaneously, with gentle slopes for easy access.

**5. What is the recommended bunk space per animal?**
Bunk space must ensure all cattle can eat at the same time without excessive aggression. Space per head varies with group size and feeding system, but adequate linear space reduces sorting and improves intake uniformity.

**6. How do you manage water troughs in feedlot pens?**
Water troughs should be placed at the fence line or within the pen, positioned to minimize contamination from manure or feed. Troughs need regular cleaning, stable footing, and protection from freezing in cold climates.

**7. What is a hospital pen and when should it be used?**
A hospital pen is a separate enclosure for sick or injured cattle. It provides clean bedding, easy access for treatment, and removal from competition. Cattle showing signs of illness or injury should be moved promptly to the hospital pen.

**8. How can feedlot managers reduce heat stress in pens?**
Heat stress mitigation includes providing shade, adjusting feeding times, ensuring ample fresh water, and maintaining airflow. Mound orientation and pen shape can affect ventilation. Sprinkler systems may be used if water and drainage are managed.

## Pen Design and Layout

### Orientation and Wind
Feedlot pens should be oriented to take advantage of prevailing winds for natural ventilation. Long pen axes are often aligned with the direction of summer winds to carry away heat and dust. Winter winds should be considered to avoid drafts in cold climates. Pen shape influences air movement, with rectangular designs generally improving air exchange compared to square pens.

### Drainage and Surface Management
The pen surface is the foundation of effective waste management. A crowned or sloped surface directs runoff to collection channels or settling basins. Base materials such as compacted clay, limestone screenings, or fly ash provide a firm, non,slip surface. The crown should be maintained through periodic grading. Drainage features include swales, ditches, and sedimentation ponds. Water should never pond within the pen.

### Mounds and Resting Areas
A well,constructed mound gives cattle a dry place to lie down and escape muddy or hot conditions. Mounds are typically built from compacted soil, sand, or a combination, with a slight crown to shed water. The mound’s length and width should accommodate the entire pen population. Access ramps with gentle slopes reduce injury risk. Mound placement near water or feed can reduce congestion.

## Feeding and Water Management

### Bunk Management
Feed bunks must be designed for easy cleaning and access. Bunk alignment along the fenceline allows delivery from an alley. Concrete bunks with smooth surfaces reduce feed wastage. Bunk space per animal should match the feeding schedule and group size. Overcrowding at the bunk increases sorting and aggressive behaviour.

### Water Supply and Quality
An adequate supply of clean water is critical for feed intake and health. Each pen should have at least two water sources to provide redundancy if one becomes contaminated or frozen. Troughs must be positioned away from high,traffic areas to minimise faecal contamination. Water flow rate should meet peak demand. Trough cleaning frequency depends on climate and feed type.

## Stocking Density and Social Structure

### Space Allowance
The floor space per animal influences mud conditions, hygiene, and social interactions. Space allowance is calculated based on animal weight, pen shape, and lying space required. Cramped pens increase injury and stress. The relationship between space and performance is well documented, but appropriate density varies by operation.

### Group Size and Sorting
Group size affects feeding behaviour and competition. Larger groups may require more bunk space per head. Sorting cattle by weight, age, or condition reduces bullying and helps uniform gain. Mixing unfamiliar animals can trigger social instability, so groups should be established early in the feeding period.

## Health and Welfare Monitoring

### Routine Observation
Pen riders check cattle daily for signs of illness, lameness, or injury. Early detection allows prompt treatment and reduces mortality. Training riders to identify subtle changes is essential. Access to hospital pens, chutes, and handling facilities supports treatment.

### Manure and Hygiene
Pen condition directly affects hoof health and respiratory disease risk. Muddy pens increase the incidence of foot rot and pneumonia. Regular scraping and addition of clean bedding (such as straw or sand) improve hygiene. Deep,bedded pens can reduce manure moisture but require more labour and material.

## Waste Management and Environmental Compliance

### Manure Storage and Application
Manure from feedlot pens is a valuable resource but must be managed to avoid nutrient runoff. Stockpiles should be covered or sited away from watercourses. Nutrient analysis guides land application rates. Composting reduces volume and pathogens.

### Runoff Control
Rainfall on feedlot pens produces runoff high in nutrients and organic matter. Settling basins, sediment traps, and vegetated filter strips capture solids before discharge. Permitted facilities must comply with local regulations for discharge and monitoring.

## Biosecurity and Vermin Control

### Entry Protocols
Each pen should have a single access point to control cattle movement and visitor entry. Vehicles and equipment used in hospital pens should not enter clean pens without cleaning. Footbaths and boot changes reduce pathogen spread.

### Rodent and Bird Management
Rodents and birds can transmit diseases and contaminate feed. Exclusion measures include feeding in bunks instead of on the ground, covering feed piles, and maintaining clean pen perimeters. Regular monitoring and targeted control programmes are advised.
