# [Beef Cow Supplementation](/knowledge/animal-farming/beef-cattle/beef-cow-supplementation-strategies-when-what-to-feed) During Late Gestation ## Key Takeaways - Late gestation (last 60-90 days) is critical for beef cows due to accelerated fetal growth, colostrum development, and the need to maintain body condition for rebreeding; supplementation must address energy, protein, and mineral deficits identified through forage analysis and body condition scoring (BCS). - Forage quality typically declines through winter, reducing digestible energy and crude protein, while cold weather increases maintenance energy requirements by up to 40%, necessitating proactive supplementation to prevent nutrient deficiencies. - Maintaining a Body Condition Score (BCS) of 5-6 on a 9-point scale at calving is crucial for improved postpartum fertility and calf vigor; cows below BCS 4.5 require immediate nutritional intervention to prevent compromised passive immunity transfer and reduced colostrum immunoglobulin G. - Supplement selection must be tailored to specific forage deficits, with protein supplements (e.g., cottonseed meal) for low-protein forages and energy supplements (e.g., corn) for low-energy forages, alongside essential minerals like phosphorus, copper, selenium, and vitamin A. - Continuous monitoring of BCS, forage intake, and environmental conditions is essential, with adjustments to supplementation frequency and composition recommended every 2-3 weeks; veterinary consultation is advised for unexplained weight loss or failure to respond to supplementation. - Over-supplementation, particularly of energy in well-conditioned cows, can lead to excessive fat deposition, calving difficulty, and metabolic disorders, while under-supplementation compromises calf birth weight, colostrum quality, and subsequent reproductive performance. --- Beef cows in late gestation require targeted nutritional management because fetal growth accelerates, colostrum development begins, and the cow must maintain body condition for rebreeding. Supplementation decisions must integrate forage quality, body condition score (BCS), and weather patterns, as these factors jointly determine whether energy, protein, or mineral deficits will compromise cow and calf outcomes. The core management framework involves assessing current forage and cow status, estimating the gap between nutrient supply and demand, selecting supplements that fill that gap without overfeeding, and adjusting delivery as conditions change. ## At a Glance | Factor | Key Point | Action | |--------|-----------|--------| | Forage quality | Declines through winter, lower digestibility and protein | Test forage and compare to published requirements ([Merck Veterinary Manual](https://www.merckvetmanual.com/)) | | Body condition | BCS 5,6 (9-point scale) at calving improves postpartum fertility and calf vigor | Score cows 60,90 days before calving and group by BCS | | Weather | Cold stress increases maintenance energy needs by 10,40% | Increase energy supplementation during cold events ([FAO Animal Production and Health](https://www.fao.org/animal-production/en/)) | | Supplement timing | Last 60,90 days of gestation most critical | Begin before forage quality drops, do not wait for body condition loss | | Monitoring | Visual signs, weight change, BCS trends, fecal condition | Adjust every 2,3 weeks, escalate to veterinarian if unexplained weight loss occurs | ## System Context ## Forage Quality and Weather Interaction Native or hay-based forages typical of winter feeding lose digestible energy and crude protein as plants mature. A forage test taken before or during late gestation provides the baseline for calculating supplementation needs. Cold weather amplifies the problem because maintenance energy requirements increase roughly 1% for each degree Celsius below the animal’s lower critical temperature ([USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms)). A cow that was adequately fed on a mild day may become energy-deficient during a cold snap, even if forage intake remains constant. The combined effect of low-quality forage and cold stress is the most common cause of late,gestation energy deficiency. ### Body Condition as an Integrator Body condition score integrates past nutritional history and current energy balance. Cows entering late gestation at BCS 4 or lower have less internal fat reserve to buffer against feed shortages and cold stress. Research indicates that nutritional restriction during late gestation reduces calf birth weight and compromises passive immunity transfer ([Influence of nutritional restriction during late gestation on production measures and passive immunity in beef cattle](https://api.elsevier.com/content/abstract/scopus_id/0025482964)). Cows in thin condition also have lower colostrum immunoglobulin G concentrations, which directly affects calf health. Therefore, BCS assessment at pregnancy diagnosis and again 60 to 90 days pre-calving is a necessary veterinary planning tool. ## Planning Decisions ### Timing and Duration of Supplementation The window for effective supplementation begins when forage quality falls below the cow’s combined maintenance and pregnancy requirements,commonly 60 to 90 days before expected calving. Producers who delay supplementation until body condition visibly declines have already allowed a substantial energy deficit, and the metabolic cost of regaining condition late in pregnancy is higher than maintaining it. Research from winter grazing systems shows that supplementation during late gestation influences also cow performance but also steer progeny growth and carcass traits ([Winter grazing system and supplementation during late gestation influence performance of beef cows and steer progeny](https://api.elsevier.com/content/abstract/scopus_id/62149107419)). This long-term impact underscores the need to plan supplementation before parturition, not as a reaction to it. ### Selecting Supplement Type Supplement composition must match the specific forage deficit. For example, low-protein forages require a protein supplement (such as cottonseed meal or soybean meal) to support rumen function and intake, whereas moderate-protein, low-energy forages call for energy supplementation (such as corn or byproduct feeds). Minerals and vitamins,particularly phosphorus, copper, selenium, and vitamin A,must also be evaluated relative to local soil and forage profiles. There is no universal “late,gestation supplement”, the formulation depends on forage analysis, cow BCS, and environmental conditions. Veterinary or extension nutritionists can interpret forage test results and recommend a supplement that corrects the margin of deficiency without overfeeding nutrients that are already adequate. ## Core Management Framework ### Monitoring and Adjustment A supplementation plan must be monitored and adjusted as forage quality changes, weather shifts, and BCS evolves. Weekly BCS assessment in a sentinel group (10,15% of the herd) provides objective data. If cows maintained on a given supplement regimen begin to lose condition, either the amount needs to increase or the supplement composition may be mismatched. Conversely, gains beyond a BCS of 6 indicate over-supplementation, which is economically wasteful and can lead to metabolic problems at calving. Fecal consistency and manure pH can sometimes indicate rumen upset from high,starch supplements, warranting a change to a more digestible fiber source. ### Veterinary Consultation and Uncertainty Late-gestation nutrition intersects with herd health in ways that cannot always be predicted from standard requirements. Cows with underlying disease (e.g., [bovine viral diarrhea virus](/knowledge/viruses/livestock-viruses/bovine-viral-diarrhea-virus) persistence, subclinical acidosis, or chronic parasitism) may not respond to supplementation as expected. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) and [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) resources provide guidance on notifiable conditions that can manifest as poor response to nutrition. If a group of cows fails to maintain condition despite apparently adequate supplementation, a veterinary health assessment is required before simply increasing feed. Uncertainty also arises when forage analysis is not available, in such cases, supplementation should err on the side of a moderate protein-energy balance instead of a high-concentrate approach, and professional sampling should be scheduled for the next feeding period. **Facilities and Environment** The environment in which late-gestation beef cows are managed directly influences nutrient partitioning and fetal development. Cows exposed to cold stress or muddy conditions increase maintenance energy requirements, which can divert nutrients away from the gravid uterus and maternal tissue reserves. [Winter grazing system and supplementation during late gestation influence performance of beef cows and steer progeny](https://api.elsevier.com/content/abstract/scopus_id/62149107419) demonstrated that cows on extensive winter range without shelter required greater supplementation to maintain body condition compared to those managed with improved grazing or drylot access. Producers should evaluate windbreaks, bedding areas, and drainage to reduce heat loss and physical exertion. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) notes that effective environmental management includes providing a dry lying area and protection from prevailing winds, particularly when wind chill falls below critical thresholds. Uncertainty remains about the precise temperature at which supplementation increments become cost-effective, therefore, local weather records and [body condition scoring](/knowledge/animal-farming/farm-management/body-condition-scoring-a-tool-for-feed-management) should guide adjustments instead of fixed calendars. **Nutrition and Water** Forage quality declines rapidly in late autumn and winter, often falling below the protein and energy requirements of a pregnant beef cow. [PubMed record 42402985](https://pubmed.ncbi.nlm.nih.gov/42402985/) and [PubMed record 42353511](https://pubmed.ncbi.nlm.nih.gov/42353511/) both show that crude protein and digestible energy in cool-season forages drop below maintenance levels during late gestation, necessitating strategic supplementation. [PubMed record 42101531](https://pubmed.ncbi.nlm.nih.gov/42101531/) and [PubMed record 42077486](https://pubmed.ncbi.nlm.nih.gov/42077486/) further indicate that energy supplementation, particularly from non-structural carbohydrates, improves body condition scores and subsequent colostrum quality. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) guidelines emphasize that supplementation should be based on forage analysis results and cow body condition instead of standardized rations. Protein supplements may be warranted when forage protein content is below 7% on a dry-matter basis, but exact thresholds vary with cow breed, parity, and expected calving date. Water intake is equally critical yet often overlooked. Reduced water consumption during cold weather can lead to decreased feed intake and metabolic dysfunction. [PubMed record 42077442](https://pubmed.ncbi.nlm.nih.gov/42077442/) found that cows offered warmed water during winter had higher voluntary dry matter intake than those consuming near-freezing water. Producers should ensure a reliable, unfrozen water supply, heated waterers or frequent tank checks are practical. The [USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms) reports that dehydration in late-gestation cows is associated with increased risk of dystocia and weak calf syndrome. **Production-Stage Decisions** The primary production decision during late gestation is the timing and composition of supplementation relative to calving date and expected forage quality. [Nutrition during mid to late gestation affects growth, adipose tissue deposition, and tenderness in cross-bred beef steers](https://api.elsevier.com/content/abstract/scopus_id/80052672148) indicates that nutritional plane in the last trimester influences also calf birth weight but also postnatal carcass characteristics, though the window of sensitivity remains debated. [Influence of nutritional restriction during late gestation on production measures and passive immunity in beef cattle](https://api.elsevier.com/content/abstract/scopus_id/0025482964) provides evidence that severe energy restriction reduces colostral immunoglobulin G concentrations, increasing calf morbidity. Conversely, over-supplementation can lead to oversized calves and calving difficulty. The decision point hinges on [body condition scoring](/knowledge/animal-farming/farm-management/body-condition-scoring-a-tool-for-feed-management): cows with a body condition score of 5 or 6 (1 to 9 scale) at 90 days pre-calving may require only moderate supplementation, while thin cows (score 4 or below) need immediate intervention. [The effect of embryonic death rates in cattle on the efficacy of estrus synchronization programs](https://api.elsevier.com/content/abstract/scopus_id/3543071787) is less directly relevant, but underscores that nutritional insults early in pregnancy carry consequences, however, late-gestation recovery is possible with targeted feeding. Professional veterinary consultation is advised when cows fail to respond to supplementation within two to three weeks. **Records** Systematic records link nutritional inputs to health outcomes. At minimum, document body condition scores at 90 days, 60 days, and 30 days pre-calving. Forage test results for crude protein, neutral detergent fiber, and total digestible nutrients should be recorded alongside supplement type, amount, and date. The [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) protocols recommend tracking any illness or calving difficulty relative to nutritional history. Records permit retrospective analysis of failure patterns, such as repeated weak calves or low weaning weights. Digital or paper logs assist veterinarians in making evidence-based adjustments. When records indicate a cluster of dystocia events, a review of supplementation timing and forage quality is warranted. **Welfare** The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) outlines that freedom from hunger, malnutrition, and environmental stress is a core welfare principle. Late-gestation cows that are under-conditioned or exposed to severe weather exhibit elevated cortisol levels, impaired immune function, and reduced udder development. [Nutrient and Immunity Transfer from Cow to Calf Pre- and Postcalving](https://api.elsevier.com/content/abstract/scopus_id/0032178016) demonstrates that maternal nutrition directly affects the transfer of passive immunity. Welfare concerns also include the pain of difficult calving, which is more common when nutritional management is inconsistent. Producers should monitor for signs of lethargy, rough hair coat, and reluctance to move, which may indicate insufficient energy or protein. Veterinary oversight is recommended when multiple cows in a cohort show declining condition despite adequate feed availability, as underlying disease (e.g., Johne’s or chronic parasitism) may be present. **Worker and [Food Safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention)** Supplement handling requires attention to mycotoxin risk, especially when using stored grains or protein meals. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) advises that moldy feed should not be fed to pregnant cattle because of potential abortifacient mycotoxins. Workers should wear gloves when handling concentrated mineral mixes to avoid dermal absorption of ionophores or trace minerals. Biosecurity measures per the [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) include not sharing feeding equipment between herds and quarantining purchased cows whose nutritional history is unknown. Because late-gestation supplementation often occurs in remote areas, emergency plans for feed delivery and water supply should be reviewed annually. No [food safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) risk is typically associated with beef from supplemented cows, but slaughter withdrawal periods for any therapeutic feed additives must be observed per label. **Failure Patterns** Common failure patterns include cows that lose body condition during the last 60 days despite apparent access to feed. This may stem from overstocking, low forage palatability, or underestimation of cold stress. Another pattern is a high incidence of calves that struggle to stand or nurse, this often traces back to energy deficiency in the last trimester. [PubMed record 42402985](https://pubmed.ncbi.nlm.nih.gov/42402985/) specifically notes that cows on low-energy forages produced calves with lower serum immunoglobulin. Failure also appears as prolonged calving intervals or high open rates in the subsequent breeding season, reflecting that late-gestation nutrition influences postpartum anestrus. When these patterns emerge, a complete audit of forage analysis, supplement composition, feeding frequency, and weather records is needed. Veterinary nutritionists can assist in formulating cost-effective rations that avoid both deficiency and waste. **Practical Monitoring** Regular body condition scoring every two to four weeks during late gestation is the most practical monitoring tool. Cows should be scored by the same person to ensure consistency. Observe forage consumption and supplement intake, if cows leave supplement or consume it aggressively, adjustments are needed. Weighing a subset of cows monthly can provide more precise data where facilities allow. Environmental monitoring includes logging daily temperature and wind speed, as these directly affect energy requirements. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) resources recommend simple visual assessment of manure consistency (loose manure may indicate excess protein, dry, firm manure may indicate insufficient water). Any deviation from expected body condition or health warrants escalation to a veterinarian or extension specialist. Professional judgment is required when interpreting results: a cow may appear thin due to age, dental problems, or parasitism instead of feed quality. Blood sampling for beta-hydroxybutyrate or non-esterified fatty acids can quantify negative energy balance but should be performed under veterinary guidance. The goal is to maintain a steady, moderate condition that supports fetal development, adequate colostrum, and a successful postpartum recovery without the expense of overfeeding. During late gestation, health observation and biosecurity protocols must be integrated with nutritional planning to optimize outcomes for beef cows and their calves. Daily visual assessment of body condition, feed bunk behavior, and fecal consistency provides early warning of nutritional imbalances or disease. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) outlines key indicators such as dull coat, lethargy, and reduced appetite that may signal metabolic disorders like pregnancy toxemia or hypocalcemia. Cows that fail to maintain adequate body condition despite sufficient energy intake warrant closer scrutiny. In research examining [Winter grazing system and supplementation during late gestation influence performance of beef cows and steer progeny](https://api.elsevier.com/content/abstract/scopus_id/62149107419), cow body condition at calving directly correlated with calf birth weight and subsequent weaning performance, underscoring the need for systematic observation. [PubMed record 42353511](https://pubmed.ncbi.nlm.nih.gov/42353511/) provides evidence that specific nutritional deficits can alter fetal organ development, highlighting the importance of early detection of thin cows. Biosecurity measures aim to prevent introduction and ## At a Glance Late gestation is a critical period for beef cows. Fetal growth accelerates, and the cow must maintain body condition to support calving and subsequent lactation. Strategic supplementation addresses nutrient gaps in forage, primarily energy and protein, while ensuring appropriate mineral and vitamin intake. The following table summarizes key considerations. | Aspect | Consideration | Purpose | |--------|---------------|---------| | Timing | Last 60 to 90 days before calving | Matches peak fetal demand and allows body condition correction | | Energy | Provided when forage quality is low or when cows are in thin condition | Supports fetal growth and prevents excessive body fat mobilization | | Protein | Needed if forage crude protein falls below 7 percent | Promotes rumen function and forage digestibility | | Minerals | Calcium, phosphorus, copper, zinc, selenium, and vitamin A are critical | Supports fetal skeletal development and immune function | | Body Condition | Target body condition score of 5 to 6 on a 9-point scale | Improves calving ease, colostrum quality, and postpartum rebreeding | | Feeding Method | Range cubes, protein blocks, liquid supplements, or hand-fed grain mixes | Depends on labor, facilities, and pasture access | | Monitoring | Regular body condition scoring and forage testing | Adjusts supplement type and amount as conditions change | | Avoidance | Over-supplementation of energy in cows with adequate condition | Prevents excessive fat deposition and metabolic problems | ## Nutritional Priorities in Late Gestation ### Energy Requirements and Forage Quality Late gestation substantially increases energy demand. The fetus gains the majority of its birth weight during this period, and the cow’s udder begins developing. If forage energy concentration is low, often due to mature or frost-damaged pasture, cows catabolize body fat to meet needs. Thin cows that enter late gestation with a body condition score below 5 require additional energy to prevent further weight loss and to maintain pregnancy. Supplementing energy with grain or high-quality hay helps cows partition nutrients toward fetal growth without compromising their own reserves. When forage quality is adequate, energy supplementation should be moderate to avoid displacing forage intake. ### Protein Supplementation Strategies Protein is essential for rumen microbial activity. Forage containing less than 7 percent crude protein limits microbial digestion, reducing the cow’s ability to extract energy from the same forage. In such cases, supplemental protein improves fiber breakdown and increases voluntary intake. Common protein sources include soybean meal, cottonseed meal, canola meal, and alfalfa hay. The amount needed depends on the degree of deficiency. Overfeeding protein above requirements does not provide additional benefit and can increase feed costs. Protein supplementation is particularly important for first-calf heifers, which have higher protein needs due to their own growth. ### Mineral and Vitamin Provision Mineral and vitamin needs rise in late gestation. Calcium and phosphorus must be balanced, excess phosphorus relative to calcium can interfere with calcium metabolism and increase the risk of milk fever at calving. Trace minerals such as copper, zinc, and selenium play roles in antioxidant defense, immune function, and enzyme systems. Vitamin A, stored in the liver, supports fetal development and newborn vigor. A complete mineral supplement formulated for late gestation should be available free choice. Salt-based mineral mixes are common, but intake can vary, careful placement and consumption monitoring help ensure adequate intake. ## Body Condition Management ### Target Body Condition Scores Body condition scoring provides an objective measure of energy reserves. For beef cows entering late gestation, a score of 5 to 6 is ideal. Cows scoring below 4.5 are considered thin and require immediate energy supplementation. Cows scoring above 7 are overly fat and may experience calving difficulty, reduced appetite, and metabolic disorders. Regular scoring every 30 days allows timely adjustments. Heifers should be managed toward the same target, but their smaller frame size and continued growth often demand slightly higher nutritional support. ### Adjusting Supplementation Based on Condition Cows that are thin at the start of late gestation need aggressive energy supplementation to gain condition before calving. The rate of gain depends on energy density of the supplement and the cow’s intake. In contrast, cows in adequate condition can be maintained with modest supplementation, often just enough to offset forage nutrient deficits. Overconditioned cows should not be fed high-energy supplements, instead, they can be provided only a mineral supplement and allowed to rely on forage. Body condition changes should be gradual, rapid gains or losses are undesirable. ## Practical Feeding Considerations ### Supplement Delivery Methods The method of delivering supplement should match the operation’s scale, labor, and infrastructure. Hand-fed range cubes or grain mixes allow precise control of individual intake, especially useful for groups with varying body condition. Protein blocks and tubs offer convenience but intake can be inconsistent. Liquid supplements require specialized feeders and careful management to avoid spoilage. Self-fed mineral feeders should be placed near water sources or loafing areas to encourage consumption. Regardless of method, all supplements must be stored and presented to maintain palatability and prevent mold. ### Avoiding Over-supplementation Over-supplementation wastes feed and can disrupt rumen fermentation. Excess energy can cause cows to become fat, increasing calving difficulty and reducing postpartum feed intake. Excess protein is excreted in urine, putting a metabolic load on the liver and kidneys. Mineral toxicity, particularly from copper and selenium, can occur when supplements are fed in excess of recommendations. The best approach is to base supplement formulations on forage test results and cow body condition. Adjustments should be small and incremental, with continuous monitoring of cow response. ## Frequently Asked Questions **1. What is the most important supplement to provide during late gestation?** Energy supplementation is often the priority when cows are thin or when forage quality is low. Protein supplementation becomes critical when forage crude protein drops below 7 percent. Minerals are always needed but can usually be provided through a balanced free-choice mineral mix. **2. How much should I feed a thin cow in late gestation?** The amount depends on the energy density of the supplement and the cow’s current weight and condition. General practice is to feed enough to achieve moderate condition gain, typically 0.5 to 1.0 pound of additional weight per day. This usually requires 2 to 4 pounds of grain or a comparable energy source per head per day. **3. Can I use hay as a supplement for late-gestation cows?** Hay can serve as both energy and protein supplement if it is of higher quality than the pasture or base forage. Alfalfa hay, for example, provides both protein and energy. Low-quality hay may not correct nutrient deficiencies and can actually dilute the overall diet quality. **4. How often should I body condition score cows?** Scoring every 30 days is recommended during late gestation. This frequency allows identification of cows losing condition early and allows time for corrective feeding before calving. Scoring at weaning, at the start of the supplementation period, and again 60 days before calving is a common schedule. **5. Do first-calf heifers need different supplementation?** Yes. Heifers have higher protein and energy requirements because they are still growing. They also need additional minerals to support their own skeletal development. Managing heifers as a separate group with a diet formulated for their needs is strongly recommended. **6. What are the risks of feeding too much grain to cows in late gestation?** Overfeeding grain can cause rumen acidosis, reduced forage intake, and excessive fat deposition. Fat cows face higher rates of dystocia, retained placentas, and metabolic disorders. Grain should be introduced gradually and limited to no more than 0.5 percent of body weight on a dry-matter basis in a single feeding. **7. Should I provide a separate mineral mix for late gestation?** A mineral mix specifically formulated for late gestation is advisable. These mixes contain higher levels of calcium and phosphorus relative to maintenance mixes and often include elevated trace minerals and vitamins. Using a mineral mix formulated for the correct stage of production prevents imbalances. **8. How do I know if my supplementation program is working?** Monitor body condition scores at regular intervals. Cows should maintain or improve condition during late gestation. Also observe calving ease, calf vigor, and colostrum quality. A veterinarian or extension specialist can help interpret forage test results and adjust the supplement formulation as needed. ## 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.
