# Dairy Cow Feed Costs: Calculating and Reducing Expenses ## Key Takeaways - Feed costs typically range from 40-60% of total dairy production expenses, with purchased protein supplements, forages, and feed waste being the primary cost drivers. Accurate calculation involves tracking all feed purchases/harvests, determining dry matter content, and calculating dry matter intake per cow to derive feed cost per cow per day and per hundredweight of milk. - Improving forage quality through timely harvest and proper fermentation is a critical strategy, allowing for increased forage inclusion in rations and reduced reliance on more expensive purchased concentrates. Forage testing is essential for accurate ration formulation based on actual nutrient content. - Minimizing feed shrink and waste, which can range from 5% to over 15%, directly reduces costs. This involves meticulous bunk management, including frequent feed push-ups, daily bunk cleaning, and proper silage face management to prevent spoilage and reduce dry matter losses. - Grouping cows by production level (e.g., fresh, high, mid, low, dry) allows for tailored rations that match specific nutrient requirements, preventing overfeeding of less productive animals and potentially enhancing performance in high-producing groups. - Monitoring body condition score (BCS) and milk production data is crucial for fine-tuning rations and ensuring economic efficiency. Excessive BCS loss or gain indicates nutritional imbalances that can lead to health issues and reduced fertility, while production data helps assess ration effectiveness and identify potential nutrient limitations. --- Feed is the single largest variable expense on most dairy operations, typically accounting for 40 to 60 percent of total production costs. For a farmer milking 100 cows, even a small reduction in daily feed cost per cow can translate into thousands of dollars in annual savings. This guide explains how to calculate your true dairy cow feed costs, identify where money is being lost, and implement practical strategies to reduce expenses without sacrificing milk production or cow health. It is written for dairy owners, herd managers, and farm employees who want a clear budgeting framework and actionable cost-cutting measures. ## At a Glance - Feed costs typically represent 40 to 60 percent of total dairy production expenses. - Calculate feed cost per cow per day by dividing total monthly feed expenses by the number of cow days in that month. - A realistic target for feed cost per cow per day is $4 to $7 for a 1,400 pound cow producing 70 to 80 pounds of milk, but regional prices vary widely. - The biggest cost drivers are purchased protein supplements, forages, and wasted feed at the bunk. - Measure dry matter intake accurately. You cannot manage what you do not measure. - Reduce feed costs by improving forage quality, minimizing shrink and waste, negotiating bulk prices, and formulating rations to match production groups. - Monitor feed cost per hundredweight of milk, not just cost per cow, to see the true economic picture. - Call a veterinarian if cows are losing body condition despite adequate feed intake, or if you suspect subclinical acidosis or other digestive disorders. ## Understanding the Components of Dairy Cow Feed Costs Before you can reduce dairy cow feed costs, you need to understand what makes up the total bill. Feed expenses fall into several categories, and each one behaves differently in your budget. ### Purchased Feeds Purchased grains, protein meals, byproducts, minerals, vitamins, and additives make up the largest cash outlay on most dairies. Common purchased ingredients include corn grain, soybean meal, canola meal, distillers grains, cottonseed, wheat middlings, and commercial mineral premixes. These prices fluctuate with commodity markets, and they are the portion of your feed bill most exposed to price volatility. ### Homegrown Forages Corn silage, haylage, alfalfa hay, grass hay, and small grain silage are often grown on the farm. The cash cost of these feeds appears lower than purchased feeds, but they carry real production costs including seed, fertilizer, fuel, machinery, labor, and land charges. Many farmers overlook these hidden costs and underestimate what their homegrown forages actually cost to produce. ### Feed Shrink and Waste Shrink is the difference between the amount of feed you purchase or harvest and the amount cows actually consume. Dry matter losses occur during harvest, storage, feedout, and at the bunk. Typical shrink rates range from 5 percent for well-managed silage bags to 15 percent or more for poorly managed bunker silos. Every percentage point of shrink is pure financial loss. ### Labor and Equipment Feeding labor, mixer maintenance, fuel, and depreciation on feeding equipment are sometimes classified separately, but they are part of the true cost of delivering feed to the cow. A ration that is cheap on paper but requires excessive mixing time or causes frequent equipment breakdowns is not actually cost effective. ### Veterinary and Health Costs Related to Feeding Poor feed management leads to metabolic disorders including ketosis, displaced abomasum, and laminitis. These conditions generate veterinary bills, treatment costs, and lost milk. When calculating the true cost of your feeding program, include the health expenses that trace back to nutritional management. ## How to Calculate Feed Cost Per Cow Accurate calculation is the foundation of cost control. You need a system that captures every pound of feed that enters the farm and every pound that goes into the mixer. ### Step 1: Track All Feed Purchases and Harvests Create a feed inventory log. For purchased feeds, record the date, tonnage, and price for every delivery. For homegrown forages, track the acres harvested, estimated yield per acre, and the production cost per acre. Keep these records in a spreadsheet or farm management software. ### Step 2: Determine Dry Matter Content Feed prices are quoted on an as-fed basis, but cows consume feed on a dry matter basis. You must convert everything to dry matter to compare feeds accurately and to calculate intake. Test forages for moisture content at harvest and again at feedout. Use a Koster tester, microwave, or send samples to a commercial forage testing lab. The formula is simple: Dry matter percent = 100 minus moisture percent As-fed pounds multiplied by dry matter percent equals dry matter pounds. For example, if you feed 20 pounds as-fed of corn silage that is 65 percent moisture, the dry matter is 35 percent. The dry matter intake from that silage is 20 times 0.35, which equals 7 pounds. ### Step 3: Calculate Daily Dry Matter Intake Per Cow Weigh the feed delivered to each group of cows over a 24 hour period. Subtract the weight of feed refused at the next feeding. The difference is the actual feed consumed by the group. Divide the group consumption by the number of cows in the group to get pounds of dry matter intake per cow per day. ### Step 4: Calculate Feed Cost Per Cow Per Day For each ingredient, multiply the as-fed pounds fed per cow per day by the as-fed price per pound. Sum all ingredients to get the daily ration cost. The formula is: Daily feed cost per cow = sum of (as-fed pounds per cow times price per as-fed pound) For a simplified example, a ration might include: - 25 pounds corn silage at $0.03 per pound as-fed equals $0.75 - 15 pounds haylage at $0.04 per pound as-fed equals $0.60 - 10 pounds alfalfa hay at $0.08 per pound as-fed equals $0.80 - 12 pounds corn grain at $0.10 per pound as-fed equals $1.20 - 6 pounds soybean meal at $0.22 per pound as-fed equals $1.32 - 1 pound mineral mix at $0.40 per pound as-fed equals $0.40 The total daily feed cost per cow is $5.07. ### Step 5: Calculate Feed Cost Per Hundredweight of Milk Feed cost per cow tells you what you are spending. Feed cost per hundredweight of milk tells you what you are getting for that spending. Divide the daily feed cost per cow by the daily milk production in hundredweights. For a cow producing 80 pounds of milk per day, production is 0.8 hundredweight. If daily feed cost is $5.07, feed cost per hundredweight is $6.34. This number is the one to benchmark against other dairies. A herd with lower feed cost per cow but much lower milk production may have a worse feed cost per hundredweight than a herd spending more per cow and producing more milk. ### Step 6: Calculate Annual Feed Budget Multiply the daily feed cost per cow by the number of cows and by 365 days. For a 100 cow herd at $5.07 per cow per day, the annual feed bill is approximately $185,000. This annual figure is what you use for enterprise budgeting and loan planning. ## Benchmarking Your Feed Costs Comparing your numbers to regional and national averages helps you spot problems. The USDA and land grant university extension services publish periodic feed cost summaries for different regions. Your local extension agent can provide state specific data. As a general planning guide for a 1,400 pound Holstein cow producing 70 to 80 pounds of milk, total dry matter intake will range from 48 to 55 pounds per day. Feed cost per cow per day will typically range from $4 to $7 depending on ingredient prices and forage quality. Feed cost per hundredweight of milk will typically range from $5 to $9. If your numbers fall well outside these ranges, investigate the cause before making changes. High feed cost per cow might reflect excellent forage quality and high milk production, which is not necessarily bad. Low feed cost per cow might reflect poor forage quality that is actually costing you more in lost production than you are saving at the feed bunk. ## The Biggest Drivers of High Feed Costs Understanding what pushes feed costs upward helps you target your reduction efforts where they will have the most impact. ### Overfeeding Protein Many rations contain more crude protein than the cow needs. Excess protein is metabolized and excreted as urea, which is wasted money and an environmental liability. Work with a nutritionist to match protein levels to the production group. High producing cows in early lactation need more protein than late lactation cows or dry cows. ### Poor Forage Quality Low quality forages have lower digestibility and lower nutrient density. Cows eat less of them and extract fewer nutrients from each pound. To compensate, you add more expensive purchased concentrates to meet energy and protein requirements. Improving forage quality is often the cheapest way to reduce purchased feed needs. ### Overfeeding Minerals and Additives Commercial mineral premixes and feed additives are convenient but expensive. Some additives have strong research support, such as monensin for improved feed efficiency in some systems. Others have weak or inconsistent evidence. Review every additive in your ration and ask your nutritionist to justify each one with research data from your production system. ### Feed Shrink and Spoilage Silage that spoils at the face, hay that sits in the rain, and fines that blow away in the wind all represent purchased nutrients that never reach the cow. Shrink is silent because it does not show up on an invoice, but it directly inflates your cost per pound of delivered nutrient. ### Bunk Management Errors Pushing up feed too infrequently, allowing feed to heat, and failing to clean out old feed before adding fresh feed all reduce intake and increase waste. Cows sort rations, leaving behind unpalatable fines and consuming the palatable grains. This sorting changes the nutrient composition of what the cow actually eats, which can reduce production and cause metabolic problems. ## How to Reduce Feed Costs Without Losing Production The goal is not simply to spend less. The goal is to spend less per unit of milk produced. These strategies focus on improving efficiency so that every dollar of feed returns more milk. ### Improve Forage Quality Forage is the foundation of the ration. Higher quality forage means you can feed more forage and less purchased concentrate. Focus on cutting forages at the correct maturity stage. Alfalfa should be cut at bud to early bloom. Corn silage should be harvested at the correct moisture content, typically 62 to 68 percent moisture for bunker silos. Proper fermentation requires good packing, rapid covering, and adequate sealing. Test every forage lot and balance rations based on actual nutrient content, not book values. Forage testing costs a small amount relative to the potential savings from accurate ration formulation. ### Reduce Feed Shrink Measure shrink and set a target. A realistic goal is under 8 percent total shrink for silage storage and feedout. Key practices include: - Pack bunker silos in thin layers, 6 inches or less, with adequate tractor weight. - Cover silos immediately after filling with oxygen barrier film and plastic. - Maintain a smooth silage face and remove at least 6 to 12 inches per day in cold weather and more in warm weather. - Clean out feed bunks daily and remove spoiled feed. - Use a mixer scale to weigh ingredients accurately. - Calibrate the mixer scale monthly. ### Negotiate Better Prices on Purchased Feeds Buying feed in bulk quantities often secures lower per ton prices. Form a purchasing cooperative with neighboring dairies to increase buying power. Compare prices from multiple suppliers and do not assume your current supplier is the cheapest. Consider locking in prices with forward contracts when commodity markets are favorable. Look for alternative byproduct feeds that are locally available. Wet distillers grains, bakery waste, citrus pulp, and other byproducts can replace more expensive traditional ingredients when priced favorably. Always test byproducts for nutrient content and dry matter, as these can vary widely between loads. ### Group Cows by Production Feeding one ration to the entire herd means you are overfeeding the low producers and possibly underfeeding the high producers. Grouping cows by production level allows you to formulate rations that more closely match nutrient needs. A typical grouping strategy includes: - Fresh cows for the first 21 days in milk - High group producing over 80 pounds per day - Mid group producing 60 to 80 pounds per day - Low group producing under 60 pounds per day - Dry cows and close up cows Each group receives a ration tailored to its production level. This reduces waste from overfeeding and can improve production in the high group. ### Use Milk Production Data to Fine Tune Rations Your Dairy Herd Improvement records or milk meter data tell you exactly what each cow is producing. Review production by group and by lactation number. If the high group is averaging 70 pounds when the ration was formulated for 85 pounds, the ration may be limiting. If the low group is averaging 65 pounds, you may be overfeeding that group. ### Monitor Body Condition Score Body condition score tells you whether cows are gaining or losing weight. Cows that are losing excessive body condition are mobilizing fat to support milk production. This is normal in early lactation, but excessive loss leads to health problems and reduced fertility. Cows that are gaining too much condition in late lactation are being overfed, which is wasted money. Score cows monthly and track changes over the lactation. Adjust ration energy density based on condition score trends. ### Improve Bunk Management Cows prefer fresh feed. Feed delivery should occur at least twice daily in most systems. Push feed up to the bunk frequently, ideally every 2 to 4 hours during the day. Provide enough bunk space so all cows can eat at the same time, typically 24 to 30 inches per cow for mature Holsteins. Keep feed in the bunk 24 hours per day with no long empty periods. But do not allow feed to sit so long that it heats or becomes unpalatable. Adjust the amount delivered so orts are 2 to 5 percent of the amount offered. ### Optimize Cow Comfort Cows that are comfortable eat more and produce more milk. Overcrowding reduces eating time and increases competition at the bunk. Provide at least one stall per cow and maintain clean, dry bedding. Ensure cows have access to fresh water at all times. Water intake drives dry matter intake, and restricted water quickly reduces feed consumption. ### Consider Feed Additives Carefully Some additives pay for themselves through improved feed efficiency or reduced metabolic disease. Examples include: - Monensin for improved feed efficiency and reduced ketosis risk in some herds - Yeast cultures for improved fiber digestion and dry matter intake - Buffers such as sodium bicarbonate for high grain rations - Organic trace minerals for hoof health and reproduction in some herds Work with your nutritionist to evaluate each additive based on your specific herd situation. Remove additives that do not show a measurable return within a defined trial period. ## Common Mistakes in Feed Cost Reduction Many well intentioned cost cutting efforts fail because of common errors. Avoid these traps. ### Cutting the Wrong Ingredient Reducing the most expensive ingredient in the ration is not always the right move. Soybean meal is expensive, but removing it may reduce milk production enough that feed cost per hundredweight actually increases. Evaluate every change on the basis of income over feed cost, not just ingredient price. ### Sacrificing Forage Quality Buying cheaper, lower quality hay or harvesting silage late to save money on drying costs is a false economy. Lower quality forage means lower intake, lower milk production, and higher purchased feed needs. The savings on forage cost are usually dwarfed by the losses in milk revenue. ### Ignoring Dry Matter Intake If you reduce ration energy density to save money and cows eat less, milk production drops. Always monitor dry matter intake when making ration changes. A drop in intake of 2 to 3 pounds per cow per day is a warning sign that the ration is not working. ### Making Sudden Ration Changes Cows need time to adapt to ration changes. A sudden switch to a cheaper ingredient can cause digestive upset, reduced intake, and a drop in milk production that lasts for weeks. Make changes gradually over 7 to 10 days. ### Focusing Only on Feed Cost Per Cow Feed cost per cow is useful, but it does not tell the whole story. A herd with low feed cost per cow but low milk production may be losing money. Always evaluate feed cost per hundredweight of milk and income over feed cost. ### Neglecting the Dry Cow Ration Dry cow nutrition affects the next lactation. Cutting costs in the dry cow ration to save money can lead to increased metabolic disease, poor colostrum quality, and reduced milk production after calving. The dry cow ration is not the place for aggressive cost cutting. ## Developing a Dairy Feed Budget A written feed budget helps you plan purchases, manage cash flow, and identify potential shortages before they become problems. ### Step 1: Estimate Herd Size and Production Start with your current milking herd size and projected milk production. If you are expanding or culling heavily, adjust these numbers. Use rolling herd average and expected production by season. ### Step 2: Calculate Annual Feed Needs For each feed ingredient, estimate the pounds fed per cow per day. Multiply by the number of cows and by 365 days to get annual as-fed needs. Add 5 to 10 percent for shrink and waste. ### Step 3: Determine Homegrown Feed Supply Estimate your expected forage production based on acreage, expected yield per acre, and historical performance. Be conservative. It is better to plan to purchase supplemental feed than to run short. ### Step 4: Calculate Purchased Feed Needs Subtract homegrown feed supply from total feed needs. The difference is what you must purchase. Multiply by expected prices to get the purchased feed budget. ### Step 5: Review Monthly Cash Flow Feed purchases are not spread evenly through the year. Hay and silage purchases may be concentrated in certain months. Byproduct feeds may be available only seasonally. Build a monthly cash flow projection to ensure you have funds available when feed purchases are due. ### Step 6: Build in a Contingency Commodity prices move. Forage yields fail. Set aside a contingency of 5 to 10 percent of the feed budget for unexpected price increases or shortages. ## Monitoring and Recordkeeping Systems You cannot control what you do not measure. A simple, consistent recordkeeping system is essential for managing feed costs. ### Daily Records Record daily: - Pounds of each feed delivered to each group - Number of cows in each group - Orts or refusals by group - Milk production by group - Any feed related problems such as off feed events or sorting ### Weekly Records Calculate weekly: - Dry matter intake per cow per group - Feed cost per cow per day - Feed cost per hundredweight of milk - Income over feed cost ### Monthly Records Review monthly: - Feed inventory by ingredient - Shrink calculations by storage structure - Body condition scores by group - Herd health events related to nutrition - Commodity market prices and forward contracting opportunities ### Recordkeeping Tools A simple spreadsheet works for many farms. Commercial herd management software can automate many calculations. Some nutritionists provide feed management software as part of their consulting service. Choose a system you will actually use consistently. ## When to Call a Veterinarian or Extension Agent Many feed cost problems are management issues you can solve yourself. But some situations require professional help. ### Call Your Veterinarian If - Cows are going off feed or showing signs of digestive upset - Multiple cows develop ketosis, displaced abomasum, or milk fever - Body condition loss is severe or rapid - Cows are showing signs of laminitis or sore feet - Milk production drops suddenly without an obvious management change - You suspect a feed toxicity or mold problem ### Call Your Extension Agent or Nutritionist If - You are formulating rations without professional help and want a review - Forage test results are confusing or you need help interpreting them - You are considering a major ration change or new ingredient - You want help benchmarking your feed costs against regional averages - You need assistance developing a feed budget or cash flow projection - You are considering a new forage storage system or feeding facility ### Call a Feed Company Representative If - You are evaluating new commercial feed products - You want pricing quotes from multiple suppliers - You need help understanding commodity market trends ## Seasonal Considerations in Feed Cost Management Feed costs are not constant through the year. Planning for seasonal patterns helps you manage cash flow and avoid panic purchases. ### Summer Heat Stress Cows eat less during hot weather. Dry matter intake can drop 10 to 15 percent during heat stress events. This reduces milk production and can create negative energy balance. Focus on providing shade, ventilation, and cool clean water. Consider feeding a higher nutrient density ration to compensate for reduced intake. Feed more frequently during cooler parts of the day. ### Fall Forage Harvest Fall is when corn silage and fall hay crops are harvested. This is a time of high cash outlay for harvest costs and storage supplies. It is also when you lock in the quality of your forages for the coming year. Do not rush harvest to save on fuel or labor costs. Quality at harvest determines feed value for the next 12 months. ### Winter Feeding Cows use more energy to maintain body temperature in cold weather. Wind and wet conditions increase maintenance requirements. Adjust rations to provide additional energy during severe cold. Keep bunks clear of snow and ice. Ensure waterers are functioning and not frozen. ### Spring Pasture and Calving If you graze dry cows or heifers, spring pasture turnout reduces stored feed needs. Spring calving brings a new group of fresh cows into the milking herd with higher nutrient demands. Plan for the transition carefully. ## Advanced Strategies for Reducing Feed Costs For farms that have mastered the basics, these advanced strategies can capture additional savings. ### Total Mixed Ration Audits Have a professional conduct a full audit of your feeding program. This includes ration formulation, feed delivery accuracy, mixer calibration, bunk management, and cow behavior observation. Many farms find that cows are not actually consuming the ration they think they are feeding. ### Precision Feeding Precision feeding means delivering the right amount of each nutrient to each group of cows. This goes beyond simple production grouping. It includes adjusting rations based on forage dry matter changes, ingredient nutrient variation, and cow body condition. Precision feeding requires frequent forage testing and close communication with your nutritionist. ### Byproduct Feed Evaluation Byproduct feeds can be highly cost effective when locally available. Evaluate opportunities for wet brewers grains, wet distillers grains, soy hulls, citrus pulp, cottonseed hulls, and bakery waste. Consider storage and handling costs when evaluating these feeds. A cheap ingredient that is difficult to store or feed may not be a bargain. ### On Farm Feed Processing Processing grains improves digestibility. Steam flaking, high moisture corn, and rolling can improve starch digestibility by 5 to 10 percent. The investment in processing equipment must be weighed against the feed efficiency gains. ### Manure Nutrient Management The nutrients in feed that cows do not utilize end up in manure. Improving feed efficiency reduces nutrient excretion and may reduce the amount of fertilizer you need to buy for crop production. Work with your agronomist to credit manure nutrients in your fertilizer budget. ## Economic Decision Making for Feed Purchases When comparing feed ingredients, use a consistent economic framework. ### Income Over Feed Cost Income over feed cost is milk revenue minus feed cost. This is the best single measure of feeding program profitability. Calculate it as: Income over feed cost per cow per day = milk revenue per cow per day minus feed cost per cow per day Milk revenue per cow per day = milk price per hundredweight times daily milk production divided by 100. For a cow producing 80 pounds per day with milk at $18 per hundredweight, milk revenue is $14.40 per day. If feed cost is $5.07 per day, income over feed cost is $9.33 per day. ### Marginal Analysis for Ration Changes When considering a ration change, evaluate the marginal return. If adding 2 pounds of a $200 per ton ingredient increases milk production by 3 pounds, is it worth it? The added feed cost is 2 pounds times $0.10 per pound, which equals $0.20 per cow per day. The added milk revenue is 3 pounds times $0.18 per pound, which equals $0.54 per cow per day. The marginal return is $0.34 per cow per day, so the change is profitable. ### Breakeven Price Calculations When comparing two feed ingredients, calculate the breakeven price. For example, if soybean meal is $400 per ton and canola meal is $350 per ton, which is the better buy? You need to compare nutrient content, not just price per ton. Soybean meal is roughly 48 percent crude protein. Canola meal is roughly 36 percent crude protein. Per ton of crude protein, soybean meal costs $400 divided by 0.48, which equals $833 per ton of protein. Canola meal costs $350 divided by 0.36, which equals $972 per ton of protein. On a protein basis, soybean meal is the better value at these prices. Similar calculations can be made for energy content using net energy for lactation values. ## Case Example: A 100 Cow Dairy To illustrate the concepts in this guide, consider a typical 100 cow Holstein dairy producing 75 pounds of milk per cow per day. ### Current Situation The herd is fed a single TMR containing corn silage, haylage, alfalfa hay, corn grain, soybean meal, and a mineral pack. Daily feed cost per cow is $5.50. Daily milk revenue at $18 per hundredweight is $13.50. Income over feed cost is $8.00 per cow per day. Annual feed cost for the herd is $5.50 times 100 cows times 365 days, which equals $200,750. ### Improvement Plan The farm implements four changes: 1. Forage testing reveals the corn silage is higher in fiber than assumed. The nutritionist reformulates the ration, reducing soybean meal by 1.5 pounds per cow per day and adding 2 pounds of corn grain. Ration cost drops by $0.25 per cow per day. 2. The farm starts feeding in two production groups. The low group receives a less expensive ration with more forage and less concentrate. Average ration cost across all cows drops by another $0.15 per cow per day. 3. Bunker management improves with better packing and daily face removal. Shrink drops from 12 percent to 7 percent. This reduces the effective cost of all silage by approximately 5 percent, saving about $0.15 per cow per day. 4. The farm negotiates a volume discount with its feed supplier by committing to a 6 month contract. This saves another $0.10 per cow per day. Total savings are $0.65 per cow per day. Annual savings are $0.65 times 100 cows times 365 days, which equals $23,725. Milk production stays constant because the ration changes were formulated to maintain nutrient intake. The farm saves over $23,000 per year without losing a pound of milk. ## The Relationship Between Feed Costs and Herd Health Feed cost reduction efforts can backfire if they compromise cow health. The metabolic diseases that follow poor nutrition cost far more than the feed savings. ### Subacute Ruminal Acidosis Feeding too much grain and too little effective fiber causes subacute ruminal acidosis. Cows do not show obvious symptoms, but they eat less, produce less milk, and have poor hoof health. The condition is often diagnosed by evaluating manure consistency, cud chewing activity, and rumen fill. ### Ketosis Negative energy balance in early lactation causes ketosis. Cows mobilize body fat faster than the liver can process it. Symptoms include reduced appetite, decreased milk production, and a sweet acetone smell on the breath. Prevention focuses on proper dry cow nutrition and a smooth transition to the lactating ration. ### Displaced Abomasum The abomasum can shift position when cows eat too little effective fiber or experience sudden ration changes. This condition requires surgical correction and causes significant milk loss. Prevention focuses on adequate forage particle length and gradual ration transitions. ### Milk Fever Low blood calcium around calving causes milk fever. Prevention starts with dry cow nutrition, particularly managing dietary potassium and calcium levels. Feed costs saved in the dry cow ration are quickly lost to milk fever treatment and reduced production. ## Building a Relationship with Your Nutritionist A good nutritionist is one of the most valuable advisors on your farm. They bring training in rumen function, ration formulation, and feed management that most farmers do not have. ### What to Expect from a Nutritionist A competent nutritionist should: - Visit your farm regularly, at least monthly - Sample and test forages - Formulate rations for each production group - Monitor milk production and milk component data - Review body condition scores - Evaluate bunk management and cow behavior - Provide feed cost analysis - Recommend ration adjustments as conditions change ### How to Work Effectively with a Nutritionist Share your production and health records openly. Tell them about any herd problems, even ones that seem minor. Ask questions when you do not understand a recommendation. Request justification for every ingredient in the ration. Hold them accountable for results. ### When to Change Nutritionists If your nutritionist is not visiting regularly, not testing forages, or not providing clear economic analysis, consider a change. The cost of a good nutritionist is small compared to the savings they can identify in your feeding program. ## Government and Industry Resources Several organizations provide information and support for dairy producers working to manage feed costs. The USDA Agricultural Research Service conducts research on dairy nutrition and feed efficiency. The Natural Resources Conservation Service offers programs that may support grazing systems and forage production improvements. Land grant university extension services in every dairy state provide forage testing, feed cost analysis tools, and educational programs. Your local extension agent can connect you with these resources. The National Mastitis Council provides guidance on udder health, which is indirectly related to feed costs because mastitis reduces milk production and feed efficiency. The FAO Dairy Production and Products division publishes information on global dairy systems and feed resource management. The FAO Animal Production and Health division provides resources on livestock feeding and nutrition. The USDA APHIS Dairy Cattle Health program monitors disease issues that can affect dairy productivity. The World Organisation for Animal Health sets international standards for animal health and welfare that can affect production practices. ## Long Term Planning for Feed Cost Stability Feed prices are cyclical and unpredictable. Long term planning helps you manage volatility. ### Forward Contracting Many feed suppliers offer forward contracts that lock in prices for future delivery. This protects you from price increases but also prevents you from benefiting from price decreases. Use forward contracts for a portion of your expected needs, not the entire amount. ### Hedging with Futures Large dairies may use commodity futures markets to hedge feed prices. This requires specialized knowledge and capital. Most small and medium dairies are better served by forward contracts and volume purchasing. ### Building Feed Storage Capacity Having adequate storage capacity allows you to buy feed when prices are low and store it for later use. Evaluate the cost of additional storage against the potential savings from buying at seasonal lows. ### Maintaining Flexibility Do not lock yourself into a single feeding system. Maintain the ability to switch between feed ingredients as relative prices change. A ration that is fixed to one set of ingredients cannot take advantage of market opportunities. ## Environmental Considerations in Feed Cost Management Feed management has environmental implications that can affect your bottom line. ### Nutrient Management Planning Excess phosphorus and nitrogen in dairy rations end up in manure. Manure nutrients can become a liability if you do not have enough cropland to utilize them. Work with your nutritionist to avoid overfeeding phosphorus and other minerals. ### Methane Emissions Dairy cows produce methane as a natural byproduct of rumen fermentation. Improving feed efficiency reduces methane emissions per unit of milk produced. Some feed additives are being developed to reduce enteric methane, though their economic value is still being evaluated. ### Carbon Footprint of Purchased Feeds Purchased feeds carry an embedded carbon footprint from their production and transportation. Locally produced feeds generally have a lower carbon footprint than feeds shipped long distances. Some markets are beginning to reward lower carbon dairy production. ## Technology and Tools for Feed Cost Management Modern tools can help you track and reduce feed costs. ### Forage Testing Laboratories Commercial forage testing labs provide detailed nutrient analysis. Most dairy nutritionists work with specific labs. Tests typically include dry matter, crude protein, NDF, ADF, starch, minerals, and calculated energy values. Some labs offer near infrared spectroscopy analysis for rapid results. ### Mixer Wagon Scales Accurate weighing is essential for feed cost control. Calibrate your mixer scale monthly using certified test weights. Many farms find their scales are off by 5 percent or more, which means they are feeding more or less than they think. ### Herd Management Software Software programs track production, reproduction, and health data. Many integrate with feed management modules. These systems can generate reports on feed cost per cow, feed cost per hundredweight, and income over feed cost. ### Feed Management Apps Mobile apps allow you to record feed deliveries, track inventory, and calculate rations from your phone. Some apps connect to cloud based platforms that your nutritionist can access. ### Automated Feed Push Up Systems Automated systems push feed up to the bunk at regular intervals without labor. These systems can improve intake and reduce sorting. The investment is significant, but labor savings and production gains may justify the cost on larger dairies. ## Training Employees on Feed Management Your employees are on the front line of feed management. They see the cows and the feed every day. Well trained employees catch problems early and prevent waste. ### Key Training Topics Train employees on: - Reading the feed bunk and adjusting delivery amounts - Recognizing signs of off feed cows - Proper mixer operation and calibration - Silage face management and storage maintenance - Water system checks and cleaning - Recording feed deliveries and orts accurately ### Creating Standard Operating Procedures Write clear standard operating procedures for every feeding task. Post them near the feed area. Review them with employees regularly and update them when practices change. ### Encouraging Employee Feedback Your employees may notice problems that you miss. Create a culture where employees feel comfortable reporting concerns about feed quality, cow behavior, or equipment function. Act on their reports promptly. ## Frequently Asked Questions ### How much does it cost to feed a dairy cow per day? Most dairy farms spend between $4 and $7 per cow per day on feed for a mature Holstein cow producing 70 to 80 pounds of milk. The exact cost depends on regional ingredient prices, forage quality, milk production level, and feeding management. Calculate your own cost by tracking all feed purchases and deliveries and dividing by the number of cow days. ### What is a good feed cost per hundredweight of milk? A reasonable target is $5 to $9 per hundredweight of milk for most Holstein herds. The number varies with milk price, feed prices, and production level. The more useful measure is income over feed cost, which is milk revenue minus feed cost. Focus on maximizing income over feed cost rather than minimizing feed cost alone. ### How can I lower my dairy feed costs without reducing milk production? Improve forage quality so cows get more nutrients from homegrown feeds. Reduce feed shrink by improving silage storage and feedout practices. Group cows by production level so you are not overfeeding low producers. Work with a nutritionist to formulate rations precisely. Negotiate better prices on purchased feeds by buying in bulk or forming a purchasing cooperative. ### What is feed shrink and how much does it cost me? Feed shrink is the difference between the amount of feed you harvest or purchase and the amount cows actually consume. It includes storage losses, spoilage, wind losses, and feed refused at the bunk. Typical shrink ranges from 5 to 15 percent depending on storage method and management. On a 100 cow dairy spending $200,000 per year on feed, each percentage point of shrink costs $2,000. ### Should I use a nutritionist to formulate my dairy rations? Most dairy farms benefit from professional ration formulation. A nutritionist has training in rumen function, nutrient requirements, and feed analysis that most farmers do not have. They can identify cost savings and production improvements that more than pay for their consulting fee. If you formulate rations yourself, at least have a professional review your program periodically. ### How often should I test my forages? Test every forage lot when it is harvested and again when you start feeding it. Forages change in nutrient content during storage. Test again every 4 to 6 weeks while feeding from a storage structure, especially if you notice changes in dry matter. Forage testing costs are small compared to the potential savings from accurate ration formulation. ### What is income over feed cost and why does it matter? Income over feed cost is milk revenue per cow minus feed cost per cow. It is the best single measure of feeding program profitability because it accounts for both the cost of feed and the value of milk produced. A ration that is cheap per cow but produces little milk may have a worse income over feed cost than a more expensive ration that supports high production. ### When should I call a veterinarian about my herd's feeding program? Call a veterinarian if cows are going off feed, losing body condition rapidly, showing signs of ketosis or milk fever, or if milk production drops suddenly. Also call if you suspect feed toxicity or mold contamination. These situations require professional diagnosis and treatment. For routine ration formulation and feed cost analysis, work with a nutritionist or extension agent. ## Related Farming Guides This section will be populated with links to additional farming guides related to dairy cattle management, feed planning, and herd nutrition.
