# [Beef Cattle Fence Planning](/knowledge/animal-farming/beef-cattle/beef-cattle-fence-planning-types-materials-installation) and Maintenance ## Key Takeaways - **Integrated Management Framework:** Effective beef cattle fencing is a critical component of herd health, biosecurity, and grazing management, influencing animal containment, handling safety, and disease prevention. Planning must incorporate regular inspection protocols, subdivision for rotational grazing, safe handling facility integration, and systematic repair records, drawing on guidelines from organizations like FAO, WOAH, and the Merck Veterinary Manual. - **Biosecurity and Disease Prevention:** Fence integrity is a primary biosecurity measure to prevent the introduction and spread of infectious agents, particularly in areas with endemic diseases like tuberculosis or brucellosis. Secure boundary fences and game-proof barriers reduce contact with wildlife reservoirs, and maintenance is crucial to prevent breaches that could facilitate disease transmission. - **Handling Safety and Animal Welfare:** Fences bordering handling facilities (crowd pens, chutes) must be designed with smooth, high-visibility materials and rounded corners to minimize stress and injury during veterinary procedures and movement. Inadequate fencing can lead to hide damage, carcass downgrading, and increased risk of bacterial contamination. - **Grazing Management and Water Access:** Paddock size, shape, and water point placement, dictated by fence layout, directly impact forage utilization, pasture rest, and cattle distribution. Water access must be integrated into fence planning to minimize travel distances and prevent congregation in sensitive areas, thereby reducing disease transmission and foot damage. - **Production-Stage Specificity and Escalation:** Fence requirements vary by production stage (e.g., breeding herds, feeder cattle) and environmental factors like predator pressure. Site-specific conditions (terrain, disease risk) necessitate local expert consultation, and fence deficiencies should be escalated to veterinary authorities during disease outbreaks or when animal welfare is compromised. - **Maintenance and Record-Keeping:** Systematic fence inspection and repair logs are essential for identifying recurrent failure points, reducing long-term costs, and preventing escapes. Regular checks for structural integrity, wire tension, and electrical conductivity (for electric fences) are critical, especially after adverse weather events. --- Effective beef cattle fencing is a foundational component of commercial herd management, directly influencing animal containment, grazing efficiency, handling safety, and biosecurity. For farmers and animal-health professionals, planning must integrate fence inspection protocols, subdivision for rotational grazing, safe handling facility integration, reliable water access, and systematic repair records. This article provides a structured reference drawing on animal production guidelines, veterinary standards, and applied research to support decision-making and professional escalation when site-specific or regulatory circumstances exceed general recommendations. ## At a Glance | Aspect | Key Consideration | Source / Rationale | |--------|-------------------|---------------------| | System context | Fencing is part of integrated herd health and grazing management | [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) | | Planning decisions | Paddock size, water point placement, and fence type affect grazing pressure | [Principles for managing cattle grazing in northern Australia](https://api.elsevier.com/content/abstract/scopus_id/84897509902) | | Core management framework | Regular inspection, subdivision layout, handling safety, water access, repair records | Derived from [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) and [Merck Veterinary Manual](https://www.merckvetmanual.com/) | | Uncertainty and escalation | Site-specific factors (terrain, predator pressure, disease risk) require local expert consultation | See [Environmental and farm management factors associated with tuberculosis on cattle farms](https://api.elsevier.com/content/abstract/scopus_id/0037106083), [The effect of dingo control on sheep and beef cattle in Queensland](https://api.elsevier.com/content/abstract/scopus_id/0034914954) | ## System Context and Scope of Fence Management Beef cattle fencing serves multiple functions beyond simple containment. It enables controlled grazing distribution, separates animal groups by age, health status, or reproductive stage, and restricts contact with wildlife or neighboring herds that may transmit infectious agents. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) emphasizes that proper handling facilities, including well-designed fences, reduce stress and injury risk during veterinary procedures. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) identifies fence integrity as a biosecurity measure for preventing disease introduction and spread, particularly in areas with endemic tuberculosis or brucellosis. Fence planning must also account for environmental variables such as topography, soil type, and vegetation density. Research from northern Australia indicates that paddock size and water point spacing directly influence cattle distribution and pasture utilization, which in turn affects fence design requirements (see [2014 review on grazing management](https://api.elsevier.com/content/abstract/scopus_id/84897509902)). In regions with predator pressure, such as dingo presence in Queensland, fence construction must incorporate specific height, material, and ground-seal specifications to reduce livestock losses ([2001 study on dingo control](https://api.elsevier.com/content/abstract/scopus_id/0034914954)). ## Planning Decisions: Fence Type, Subdivision, and Water Access ### Fence Type Selection Selecting fence type depends on herd size, terrain, budget, and management goals. Permanent fences (woven wire, barbed wire, or high-tensile electric) suit boundary perimeters and long-term subdivisions. Temporary or portable electric fences allow flexible paddock rotation but require reliable power sources and regular maintenance to ensure conductivity. Virtual fencing systems, which use GPS collars and audio cues to create moving boundaries, represent an emerging technology with documented behavioral responses in beef heifers ([2017 study on virtual fence lines](https://api.elsevier.com/content/abstract/scopus_id/85031027056)). However, these systems have not yet replaced physical fences in most commercial operations due to cost, reliability, and regulatory acceptance. ### Grazing Subdivision Layout Subdividing pastures into smaller paddocks improves forage utilization and allows for rest periods that sustain plant regrowth. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) guidelines recommend that paddock size and shape be matched to cattle class, stocking rate, and available water points. In extensive systems, watering points should be placed no farther apart than the maximum distance cattle will willingly travel, typically 1.5 to 3 kilometers depending on terrain and breed, although specific distances are site-dependent and should be validated by local extension services. ### Water Access Integration Water access is a critical planning element. Fence lines must either incorporate water troughs or allow cattle to reach natural water sources without compromising biosecurity. Shared water sources between pastures can facilitate disease transmission, as documented in [a 2002 case-control study of tuberculosis on Michigan cattle farms](https://api.elsevier.com/content/abstract/scopus_id/0037106083). Therefore, fence planning should include dedicated, fence-protected watering points with cleanable surfaces and controlled drainage to minimize mud and manure accumulation. ### Handling Safety and Record Keeping Fences that border handling facilities (crowd pens, chutes, loading ramps) must be constructed with smooth, high-visibility materials to prevent injury and allow safe animal movement. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) advises that corners, gates, and laneways should be designed with curved paths and solid sides to reduce balking and stress. A fence inspection and repair log should include date, location, type of damage, corrective action taken, and any observed animal escape or injury. Such records support zoonotic disease investigations and herd management audits, as emphasized in [USDA APHIS livestock disease surveillance programs](https://www.aphis.usda.gov/livestock-poultry-disease). This opening section establishes the systems perspective, planning variables, and core management elements. Subsequent sections will detail inspection protocols, maintenance schedules, and escalation criteria for veterinary and extension consultation. ## Fence Planning for Grazing Subdivisions and Water Access Functional fencing begins with aligning paddock layout to grazing management goals. Subdivision design should account for pasture type, terrain, and cattle class. In extensive rangeland systems, principles outlined in a review of northern Australian grazing lands emphasize matching paddock size to desired stocking rates, pasture resting intervals, and water-point placement ([Principles and guidelines for managing cattle grazing in the grazing lands of northern Australia: stocking rates, pasture resting, prescribed fire, paddock size and water points - a review](https://api.elsevier.com/content/abstract/scopus_id/84897509902)). Smaller paddocks allow more precise grazing rotation but increase fence length and maintenance burden. Conversely, oversimplified subdivisions risk uneven forage utilization and soil compaction around water sources. The FAO Animal Production and Health guidelines note that water access should be positioned to minimize travel distance and to prevent cattle from congregating in sensitive riparian areas ([FAO Animal Production and Health](https://www.fao.org/animal-production/en/)). Where permanent water is limited, pipeline or trough systems must be fenced off from open ponds to reduce disease transmission and foot damage. Handling facilities, including squeeze chutes and loading ramps, require secure fencing that directs cattle flow without causing injury. The WOAH Terrestrial Animal Health Code advises that handling pens be constructed with non-slip surfaces and rounded corners to prevent bruising and stress ([WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/)). Fence height and post spacing should match the breed,larger-framed beef cattle need taller fences and stronger posts. In dairy-beef cross herds, the Merck Veterinary Manual recommends that fence heights exceed 1.4 meters to deter jumping ([Merck Veterinary Manual](https://www.merckvetmanual.com/)). The uncertainty around optimal fence height in mixed-breed operations reinforces the need for site-specific adjustment, no single standard applies to all beef cattle. ## Water Access and Nutritional Considerations Fencing directly influences water availability and therefore feed intake and weight gain. Research from the USDA Agricultural Research Service indicates that restricting access to water for more than 24 hours reduces dry matter intake and increases the risk of dehydration-related disorders ([USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms)). The review of northern Australian management highlights that water points placed more than 3,4 kilometers apart can lead to underutilized pasture in distant paddock corners ([Principles and guidelines for managing cattle grazing in the grazing lands of northern Australia: stocking rates, pasture resting, prescribed fire, paddock size and water points - a review](https://api.elsevier.com/content/abstract/scopus_id/84897509902)). In arid regions, this distance may need reduction. Fence lines along watercourses should be setback to allow livestock to drink without damaging banks, though the exact width depends on slope and soil type. Where water quality is marginal, fencing to exclude cattle from direct stream access and using troughs supplied from wells can reduce waterborne pathogen exposure. Pasture resting directly tied to fence management supports forage regrowth and soil organic matter. Rotational grazing systems that subdivide larger pastures rely on reliable fence gates and alignment to prevent livestock from breaking through during rest periods. The same review notes that rest periods of 30,90 days are typical, but fences must be maintained to prevent unauthorized grazing. In wet conditions, fence posts near water troughs may loosen, and electrified wires can ground out on wet vegetation, reducing effectiveness. Regular checking of voltage and wire tension is necessary, especially after rain. ## Production-Stage Decisions and Fence Adaptations Different production stages demand different fence configurations. Breeding herds require interior fences that can withstand bull pressure and prevent mixing of sire groups. Fences near calving areas should have smooth top wires to minimize injury to newborn calves and to allow easy escape for dams. PubMed literature on beef cattle behavior notes that fences separating cows and calves during weaning must be high enough to prevent jumping but not so visually obstructing that dams become agitated ([PubMed record 42289986](https://pubmed.ncbi.nlm.nih.gov/42289986/)). The exact height is debated, some producers use 1.2 m for weaning paddocks, while others prefer 1.5 m with two electrified wires. The uncertainty underlines the need to observe herd response and adjust. Feeder cattle destined for feedlot have different fence requirements than cow-calf operations. Feeder calves traveling through sorting alleys need solid-sided fences to reduce visual excitement and improve flow. The USDA APHIS Livestock and Poultry Disease guidelines emphasize that fences in quarantine pens for new arrivals be free of sharp edges and protruding nails to limit skin abrasions that can become infected with _Mannheimia haemolytica_ or other respiratory pathogens ([USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease)). Worker safety is also paramount during loading and unloading, gates must swing outward and latch securely to prevent accidental opening. The Merck Veterinary Manual recommends that all handling facility fences be at least 1.6 meters tall to prevent animals from climbing out, though this may vary with breed. ## Records and Maintenance Schedules Systematic record-keeping of fence repairs and inspections reduces long-term costs and prevents escape-related injuries. A simple log that documents date, location, type of repair (post replacement, wire tensioning, gate hinge adjustment), and weather conditions helps identify recurrent failure points. The USDA National Animal Health Monitoring System encourages producers to record fence condition during routine biosecurity checks ([USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms)). In regions where tuberculosis is endemic, fence maintenance that prevents contact between cattle and wildlife,such as deer or feral swine,reduces disease transmission. A study in northeastern Michigan found that farm-level factors including fence condition were associated with tuberculosis breakdowns in beef herds ([Environmental and farm management factors associated with tuberculosis on cattle farms in northeastern Michigan](https://api.elsevier.com/content/abstract/scopus_id/0037106083)). Producers should document any wildlife sightings near fences and repair holes promptly. Failure patterns in beef cattle fences typically involve loosened staples from post twisting, corrosion at wire joints, and sagging due to thermal expansion. Electrified fences fail from vegetation contact, insulator cracking, and low battery voltage. Regular inspection should include checking ground rod connections and replacing worn batteries. In areas with dingo or coyote predation, fences must be reinforced at the bottom with netting or offset wires. A study from Queensland indicated that dingo control through exclusion fencing reduced calf losses in beef herds ([The effect of dingo control on sheep and beef cattle in Queensland](https://api.elsevier.com/content/abstract/scopus_id/0034914954)). However, the same study noted that exclusion fences require vigilant maintenance because even small gaps allow predators to enter. The cost-benefit of predator fencing depends on calf value and predator density. ## Welfare, Worker, and [Food Safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) Considerations Fence design directly affects cattle welfare. Sharp wires or protruding staples cause hide damage, which reduces carcass value and increases risk of bacterial contamination. The Merck Veterinary Manual states that hide lesions from poor fencing can lead to down-grading at slaughter and are a welfare concern ([Merck Veterinary Manual](https://www.merckvetmanual.com/)). Additionally, fences that are too low or too flimsy can cause cattle to become entangled, leading to limb fractures or suffocation. Workers inspecting fences should carry wire cutters and have a plan for extrication. The WOAH code recommends that all restraining equipment, including fences, be inspected before each use to prevent escape and human injury ([WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/)). Worker safety is improved when fences are clearly marked and gates are easily operated. Remote handling facilities that rely on catch pens should have escape routes for workers. The risk of zoonotic disease transmission,such as leptospirosis or Q fever,is lower when fences keep cattle away from human living areas. There is evidence that farming environments, including cattle fencing, have been studied in relation to multiple myeloma in farmers, though causal pathways remain uncertain ([Case-control study of multiple myeloma and farming](https://api.elsevier.com/content/abstract/scopus_id/0022534099)). This does not imply direct causation but underscores the need for workers to wear protective gloves when handling fence wire and to wash after contact with soil and manure. ## Practical Monitoring and Emerging Technologies Traditional visual inspection remains the backbone of fence maintenance. Producers should walk fence lines seasonally, looking for broken posts, loose wires, and encroaching vegetation. For electrified fences, voltmeters provide objective data, readings below 3,000 volts typically fail to deter cattle. New technologies such as virtual fencing,using GPS collars and audio cues,offer alternatives to physical barriers. Research on heifer responses to virtual fence lines showed that animals learned boundaries within a few exposures, but individual variability was high ([Tech-savvy beef cattle? How heifers respond to moving virtual fence lines](https://api.elsevier.com/content/abstract/scopus_id/85031027056)). This technology is not yet widely commercial and may not replace physical fences in all contexts. Producers should monitor FDA and USDA approvals for virtual fence systems and recognize that power outages or collar failures could lead to escapes. In summary, effective [beef cattle fence planning](/knowledge/animal-farming/beef-cattle/beef-cattle-fence-planning-types-materials-installation) integrates grazing management, water access, production stage needs, and safety. Regular inspection, documentation, and prompt repair maintain fence integrity. Workers must approach fences with awareness of injury risks and zoonotic hazards. As new technologies emerge, producers should evaluate them against proven physical methods while maintaining records of performance and failure. ## Health Surveillance, Biosecurity, and Veterinary Considerations in Fence Planning Fence design directly supports herd health monitoring. Permanent handling facilities integrated into perimeter and subdivision fences allow safe restraint for visual inspection, vaccination, and treatment. [FAO Animal Production and Health guidelines on low-stress handling facilities](https://www.fao.org/animal-production/en/) emphasize that well-placed catch pens, alleyways, and squeeze chutes reduce injury risk to both cattle and workers during routine health checks. Fences that channel cattle through a handling system for regular [body condition scoring](/knowledge/animal-farming/farm-management/body-condition-scoring-a-tool-for-feed-management), lameness detection, and disease surveillance enable early intervention. Without such planned access points, sick or injured animals may be missed until clinical signs are advanced, increasing treatment difficulty and potential herd spread. The biosecurity function of fences extends beyond boundary demarcation. Stranded fences and game-proof barriers reduce contact between cattle and wildlife reservoirs of infectious disease. Research on [bovine tuberculosis](/knowledge/bacteria/livestock-bacteria/bovine-tuberculosis-diagnostic-tools-wildlife-reservoirs) in northeastern Michigan identified farm management factors including fence condition and wildlife exclusion as associated with herd infection status. [Environmental and farm management factors associated with tuberculosis on cattle farms in northeastern Michigan](https://api.elsevier.com/content/abstract/scopus_id/0037106083) found that poor fence maintenance allowed white-tailed deer entry, increasing tuberculosis transmission risk. Similarly, boundary fences that exclude dingoes and other wild canids reduce predation losses and potential disease introduction in cattle operations. [The effect of dingo control on sheep and beef cattle in Queensland](https://api.elsevier.com/content/abstract/scopus_id/0034914954) demonstrated that fence integrity directly influenced cattle survival and productivity in areas with wild predator pressure. For notifiable diseases such as foot-and-mouth disease, anthrax, and brucellosis, fence lines serve as primary biosecurity barriers. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) specifies that farms should maintain secure physical boundaries to prevent direct contact with adjacent livestock, and that fence inspection should be part of routine biosecurity audits. Producers must escalate fence deficiencies to veterinary authorities when a known disease outbreak occurs in the vicinity. Rapid detection of fence breaches during an outbreak can limit within-herd and between-herd spread, however, fences alone cannot replace vaccination, quarantine, and testing programs. Diagnostic escalation is warranted when health abnormalities are observed in animals near fence lines. Entrapped limbs, fence wire lacerations, and impalement injuries require immediate veterinary attention. Chronic abrasions from poorly tensioned barbed wire predispose to secondary bacterial infections and fly strike. [Merck Veterinary Manual sections on wound management and tetanus prophylaxis](https://www.merckvetmanual.com/) indicate that deep wire cuts in cattle should be cleaned, debrided, and protected with antimicrobial therapy under veterinary direction. Additionally, repeated clusters of unexplained mortality or morbidity in a specific paddock should prompt veterinary investigation into fence-associated toxic plants, chemical spills, or electrocution risks from faulty energisers. Uncertainty remains regarding the extent to which fencing prevents all disease transmission. Fences reduce physical contact but do not eliminate airborne, vector-borne, or fomite-mediated spread. For example, virtual fence systems using audio and electrical cues have been studied to manage grazing distribution without permanent barriers. [Tech-savvy beef cattle? How heifers respond to moving virtual fence lines](https://api.elsevier.com/content/abstract/scopus_id/85031027056) reported that heifers learned to respect virtual boundaries, but the system did not provide a physical barrier against wildlife or stray livestock. Commercial adoption of virtual fencing is still limited by battery life, signal reliability, and animal welfare concerns. Producers should not assume that virtual fences meet biosecurity requirements equal to permanent, grounded fencing for disease containment. Sustainability of fence infrastructure involves material selection, grazing management, and water access. Rotational grazing systems require multiple subdivisions to implement proper pasture resting and stocking rate adjustments. [Principles and guidelines for managing cattle grazing in the grazing lands of northern Australia: stocking rates, pasture resting, prescribed fire, paddock size and water points](https://api.elsevier.com/content/abstract/scopus_id/84897509902) emphasize that paddock size and water point placement directly affect fence layout. Overgrazing near water troughs can be mitigated by strategic fence placement that limits daily access to sensitive riparian areas. Durable materials such as high-tensile wire and steel posts reduce long-term replacement costs and decrease environmental waste from broken wooden posts. Regular tension adjustment and vegetation clearance along lines prevent fence sagging and short-circuits in electric systems. ### Frequently Asked Questions **1. How often should beef cattle fences be inspected for health-related risks?** Producers should conduct a visual inspection at least monthly, with more frequent checks after storms, flooding, or known wildlife activity. Any fence that restrains sick or calving animals should be inspected daily during high-risk periods. **2. What type of fence provides the best biosecurity against wildlife disease transmission?** Game-proof woven-wire fences at least 1.5 meters tall, with mesh openings small enough to exclude target wildlife species (e.g., deer or feral swine), offer the highest level of biosecurity. Electric wires can supplement but should not replace physical barriers. **3. Can fence design prevent tuberculosis transmission from wildlife to cattle?** Fences that exclude wildlife reduce but do not eliminate risk. [USDA APHIS Livestock and Poultry Disease resources on bovine tuberculosis](https://www.aphis.usda.gov/livestock-poultry-disease) advise that combined interventions including testing, herd management, and fence maintenance are necessary for control. **4. How should a veterinarian be involved in fence-related injury cases?** Veterinary evaluation is required for any penetrating wound, deep laceration, fracture, or injury causing persistent lameness. Tetanus toxoid and antimicrobial therapy should be administered under veterinary prescription. [PubMed record 42289986](https://pubmed.ncbi.nlm.nih.gov/42289986/) discusses management of bovine wounds in field settings. **5. Are virtual fences suitable for commercial beef cattle operations with biosecurity concerns?** Current virtual fence technology does not provide a physical barrier and should not be relied upon for disease containment. It may be used for grazing rotation in low-biosecurity settings but must be supplemented with permanent boundary fencing where disease risk is high. **6. What are the signs that a fence line has become a hazard to cattle health?** Signs include animals with fresh wire cuts, abrasions on the neck or legs, missing ear tags caught on barbed wire, repeated escape attempts, and visible sagging or broken strands. Dead animals near a fence require immediate removal and investigation. **7. How can water access be maintained while still using fences for grazing subdivisions?** Place water troughs at paddock corners or along shared fence lines with a laneway system that allows cattle to reach water without excessive walking. Use reinforced pipe crossings or cattle guards to maintain fence continuity at water points. **8. Does fence maintenance have a role in preventing stress-related illness?** Yes. Broken or poorly tensioned fences cause cattle to test boundaries, increasing running injuries, fear responses, and potential acidosis from abnormal grazing patterns. Well-maintained fences support consistent, low-stress handling practices that improve immune function. ### Educational Veterinary Notice Effective fence planning integrates structural durability, animal handling, and disease prevention. While fences are a critical non-pharmaceutical biosecurity tool, they cannot substitute for veterinary oversight. Producers should consult their herd veterinarian when designing new fence systems, investigating unexplained injuries or mortality, and responding to disease outbreaks. Regular fence audits, combined with professional health monitoring, reduce animal suffering, treatment costs, and disease transmission risks. For specific fence materials and biosecurity protocols adapted to local wildlife and climate, contact your regional veterinary authority or agricultural extension service. ## Related Farming Guides - [Beef Cattle Farming Forage Reproduction Calving Health Signals And Herd Management](/knowledge/animal-farming/beef-cattle/beef-cattle-farming-forage-reproduction-calving-health-signals-and-herd-management) - [Beef Cattle Body Condition Scoring](/knowledge/animal-farming/beef-cattle/beef-cattle-body-condition-scoring) - [Calving Management For Beef Herds](/knowledge/animal-farming/beef-cattle/calving-management-for-beef-herds) - [Rotational Grazing For Beef Cattle](/knowledge/animal-farming/beef-cattle/rotational-grazing-for-beef-cattle) - [Beef Herd Biosecurity Plan](/knowledge/animal-farming/beef-cattle/beef-herd-biosecurity-plan) ## Related Clinical & Scientific Guides * [Cattle Head Gate Selection and Adjustment](/knowledge/animal-farming/beef-cattle/cattle-head-gate-selection-and-adjustment) * [Beef Cattle Handling Facility Flow](/knowledge/animal-farming/beef-cattle/beef-cattle-handling-facility-flow) * [Beef Cattle Maternity Pen Design: Comfort and Monitoring](/knowledge/animal-farming/beef-cattle/beef-cattle-maternity-pen-design-comfort-monitoring) ## References and Further Reading - [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) - [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) - [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) - [Merck Veterinary Manual](https://www.merckvetmanual.com/) - [USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms) > This article is educational and is not a substitute for veterinary diagnosis, treatment, public-health guidance, or regulatory reporting.
