# Feed Budgeting for Mixed Crop-Livestock Farms ## Key Takeaways - A feed budget is a written plan matching monthly animal feed demand (driven by animal count, average weight, and stage of production) against available feed supply (produced or purchased), accounting for a 10-15% safety margin for spoilage and waste. - Accurate feed budgeting necessitates measuring feed in dry matter (DM) rather than "as fed" weight, as moisture content significantly impacts actual nutritional value, especially in silage and haylage. - Forage testing is critical for determining DM, protein, and energy content, enabling precise matching of feed quality to specific animal classes (e.g., high-quality forage for lactating dairy cows, lower quality for dry beef cows). - Mixed crop-livestock farms can leverage crop residues (e.g., corn stalks) and manure nutrients to reduce stored feed demand and fertilizer costs, but their feed value must be accurately assessed and matched to appropriate animal classes. - Proactive decision-making based on defined thresholds (e.g., supply covering <80% of demand, body condition score <4 at calving) is essential, prompting actions like early feed purchases, herd adjustments, or improved grazing management before critical shortfalls occur. - Regular monitoring (monthly reviews, weighing feedouts, tracking body condition scores) and detailed recordkeeping of field yields, harvest data, and animal performance are vital for maintaining budget accuracy and identifying deviations from the plan. --- Planning your feed supply before you need it is the difference between a farm that absorbs a dry year and one that sells breeding stock at a loss. This guide explains how to build a practical feed budget for a mixed crop-livestock operation, track inventory through the year, and adjust when conditions change. It is written for farmers who grow crops and raise livestock together and want a clearer picture of how many animals their land can actually carry. A feed budget is not a guess about next winter. It is a written plan that matches the feed you can produce or buy against the feed your animals require, month by month. On a mixed farm, the budget connects your cropping decisions to your stocking rate. It tells you whether to plant more silage corn, sell some calves early, or line up hay from a neighbor before prices spike. The sections below walk through the calculations, the recordkeeping, the common mistakes, and the warning signs that you need outside help. ## At a Glance - A feed budget matches animal demand against feed supply for a full 12 month cycle, not just winter. - Start with the number of animals, their average weight, and their stage of production. These three numbers drive everything else. - Weigh or estimate your stored feed in dry matter, not as fed. Moisture hides how much energy you actually have. - Account for storage loss, feeding waste, and a 10 to 15 percent safety margin before you call the budget balanced. - Revisit the budget every 30 to 60 days and after any major weather event or market shift. - Forage testing is the single best investment you can make in feed budgeting accuracy. - If you cannot cover 100 percent of demand with your own feed, lock in purchases early rather than buying spot market in winter. - Keep written records of every field, every cutting, every bale, and every animal group. The budget is only as good as the inventory behind it. ## Why Mixed Farms Need a Feed Budget Mixed crop-livestock farms have an advantage over specialized operations because they can shift resources between enterprises. Crops provide grain and straw that feed animals, and animals provide manure that feeds the soil. But that same flexibility creates a planning problem. When one enterprise changes, the other feels it. A wet spring that delays corn planting reduces silage yield and forces you to cull cows. A strong hay market tempts you to sell what your herd needs to eat. A feed budget makes those tradeoffs visible before you commit. It forces you to answer a simple question: how many animal days of feed do I have on hand, and how many do I need? Without that answer, you are making decisions on hope. Feed is typically the largest variable cost on a livestock operation. For beef cow-calf operations, feed and forage can account for 40 to 60 percent of annual production costs. For dairy, feed costs regularly exceed 50 percent of total costs. A 10 percent error in your feed inventory can mean the difference between a profitable year and a loss. The budget is your tool for finding that error early. The planning horizon matters as much as the plan itself. Most feed budgets run on a 12 month cycle that starts when the first cutting of hay goes up or when corn silage goes into the bunker. You plan from that point forward, matching the feed you have harvested against the animals you intend to carry. A calendar year budget is easier to track but less useful because the growing season does not match the tax year. Align your budget with your harvest cycle instead. ## Understanding Animal Feed Demand Before you can budget feed, you need to know what your animals require. The calculation starts with three numbers: animal count, average body weight, and stage of production. These numbers change through the year, so you need a month by month picture. ### Dry Matter Intake Basics Every animal eats a percentage of its body weight in dry matter each day. For most ruminants, that figure falls between 2 and 3.5 percent. A mature beef cow weighing 1,200 pounds will consume about 26 pounds of dry matter per day at 2.2 percent of body weight. A lactating dairy cow at 1,400 pounds may eat 50 pounds of dry matter per day because her production demands more energy. Sheep and goats run slightly higher as a percentage of body weight, often 3 to 4 percent. The stage of production changes intake more than any other factor. A dry, pregnant cow in the second trimester eats less than the same cow nursing a calf in peak lactation. The table below shows typical dry matter intake ranges for common livestock classes. | Animal Class | Body Weight (lb) | Dry Matter Intake (% of BW) | Daily Dry Matter (lb) | |---|---|---|---| | Dry beef cow, mid gestation | 1,200 | 2.0 to 2.2 | 24 to 26 | | Lactating beef cow | 1,200 | 2.5 to 3.0 | 30 to 36 | | Lactating dairy cow | 1,400 | 3.5 to 4.0 | 49 to 56 | | Growing beef steer | 800 | 2.5 to 3.0 | 20 to 24 | | Ewe, early lactation | 150 | 3.5 to 4.0 | 5.3 to 6.0 | | Doe goat, lactating | 130 | 3.5 to 4.5 | 4.6 to 5.9 | | Growing pig | 150 | 4.0 to 5.0 | 6.0 to 7.5 | These numbers are starting points, not rules. Your animals may eat more or less depending on breed, weather, forage quality, and health status. The budget works better when you adjust these figures based on your own observation and your own feed tests. ### Calculating Herd Demand To calculate total herd demand, multiply the daily dry matter intake per animal by the number of animals in each class, then multiply by the number of days in each feeding period. Add all classes together to get total herd demand. Here is a simplified example for a beef operation with 40 cows and a 180 day winter feeding period. Each cow weighs 1,200 pounds and eats 26 pounds of dry matter per day. Total daily demand is 40 times 26, which equals 1,040 pounds of dry matter per day. Over 180 days, the herd needs 187,200 pounds of dry matter, which is 93.6 tons. That number is the minimum. Add 10 to 15 percent for waste and uncertainty, and the target becomes 206,000 pounds or 103 tons of dry matter. If you are feeding round bales that weigh 1,000 pounds each at 85 percent dry matter, each bale provides 850 pounds of dry matter. You need 243 bales to cover the winter. Most farmers who have been through a hard winter will tell you to round that up. ### Accounting for Grazing Days On a mixed farm, grazing days reduce your stored feed demand. Every day animals spend on pasture is a day you do not feed hay. The budget should count those days carefully. Estimate pasture yield by walking the fields and assessing forage density, or use your own past records. A good mixed pasture in the upper Midwest might produce 3 to 4 tons of dry matter per acre over a season. Poor pasture in a dry year might produce half that. The key is to be honest about what your land actually grows, not what you wish it would grow. To calculate grazed dry matter, multiply the pasture yield per acre by the number of acres. Then divide by the total daily herd demand to find how many grazing days your pasture provides. If that number falls short of your planned grazing season, the difference must come from stored feed. Grazing management changes the math. Rotational grazing with adequate rest periods can increase effective yield by 20 to 30 percent compared to continuous grazing. But that increase requires fencing, water, and management time. The budget should reflect your actual system, not an ideal one. ## Measuring Your Feed Supply The supply side of the budget starts with inventory. You cannot budget what you have not measured. This means weighing bales, measuring silage piles, and testing forage quality. ### Hay Inventory and Bale Weight The most common mistake in feed budgeting is counting bales instead of weighing them. Bale weight varies enormously with moisture, density, baler settings, and crop. Two bales that look identical can differ by 200 pounds or more. A budget built on assumed bale weights will fail. Weigh every bale if you can, or weigh a representative sample of 10 to 20 bales from each field and cutting. Use the average weight for that lot. If you buy a bale scale or use a loader with a weigh system, the investment pays for itself the first winter. Record each lot separately. A first cutting bale of mature grass hay is not the same as a second cutting bale of alfalfa. They have different protein and energy values, and they need to be fed to different animal classes. Mixing them in your inventory hides those differences. ### Dry Matter Content Forage moisture is the hidden variable in feed budgeting. Hay that is baled at 18 percent moisture contains 82 percent dry matter. The same bale baled at 12 percent moisture contains 88 percent dry matter. Over a 1,000 pound bale, that is a 60 pound difference in actual feed value. Test moisture with a probe or send samples to a lab. Do not guess. Hay that feels dry can still contain 15 to 20 percent moisture, especially in the center of the bale. Silage and haylage are even more moisture sensitive. Corn silage typically runs 60 to 70 percent moisture, meaning only 30 to 40 percent is dry matter. A silage pile that weighs 100 tons as fed may contain only 35 tons of dry matter. This is where feed budgets go wrong most often. ### Measuring Silage and Haylage Measuring silage inventory requires knowing the density of the pile or bunker. The standard method is to calculate the volume in cubic feet and multiply by an estimated density. Corn silage in a bunker silo typically packs to 40 to 50 pounds of dry matter per cubic foot. Haylage runs lighter at 18 to 25 pounds of dry matter per cubic foot. Measure the length, width, and height of the silage face, then multiply to get cubic feet. Subtract the amount you have already fed out. This gives you remaining volume. Multiply by your estimated density to get remaining tons of dry matter. The density estimate is the weak point. If you do not know your actual packing density, use a conservative figure and check it against what you actually feed out. When you empty a silo, compare your estimated tons to the actual tons you fed. Adjust future estimates accordingly. ### Forage Testing Forage testing is not optional for a serious feed budget. A lab analysis gives you the dry matter, protein, energy, and fiber content of each forage lot. Without those numbers, you are matching unknown feed against known animal requirements. Sample hay with a core probe, taking 15 to 20 cores from multiple bales in a lot. Sample silage from the face of the pile, avoiding spoiled areas. Send samples to a certified forage testing lab. The cost is small compared to the cost of underfeeding or overfeeding. Use the test results to sort forages by quality. High protein alfalfa goes to lactating animals or growing youngstock. Mature grass hay goes to dry cows or ewes in early gestation. This matching is the core of good feed budgeting. It stretches your high quality feed and protects your low quality feed from being wasted on animals that need more. ## Building the Feed Budget Step by Step A feed budget comes together in a logical sequence. Work through these steps in order and you will have a plan you can defend. Skip steps and you will have a guess. ### Step 1: Set the Planning Period Decide when your feed year starts and ends. For most mixed farms, the year starts at first harvest, usually May or June for hay and September for corn silage. The year ends just before the next first harvest. Mark the start and end dates on a calendar and commit to reviewing the budget at set intervals. ### Step 2: Inventory All Feed on Hand Weigh or measure every lot of hay, silage, grain, and byproduct feed you have stored. Record the tons as fed, the estimated dry matter, and the tons of dry matter. Keep a separate line for each lot so you can track quality differences. ### Step 3: Estimate Future Feed Production For standing forage, estimate what you expect to harvest from each field. Use your five year average as a baseline, then adjust for current conditions. A dry spring means lower yields. A wet spring may delay harvest and reduce quality. Be conservative. It is easier to add feed to the budget than to subtract animals. For grain, use your expected yield per acre and the acres planted. Remember that some grain goes to the market and some stays on the farm. The budget should only count the portion you plan to feed. ### Step 4: Calculate Animal Demand by Month List every animal group on the farm. For each group, record the number of head, average weight, and stage of production for each month of the year. Calculate daily dry matter intake for each group, then multiply by the days in each month. This is the most detailed step in the process, and the most valuable. A cow that calves in March has very different feed needs in January than a cow that calves in May. Your budget must reflect those differences. ### Step 5: Match Grazing to Demand Subtract the days you plan to graze from the total days in each month. The remaining days are stored feed days. Multiply stored feed days by daily herd demand to get total stored feed needed. ### Step 6: Compare Supply to Demand Add up all stored feed dry matter from your inventory and expected production. Compare that total to the stored feed needed from Step 5. If supply exceeds demand by at least 15 percent, you have a workable budget. If not, you need to make adjustments. ### Step 7: Make Adjustments If you are short, you have four options. You can buy feed, sell animals, extend grazing, or reduce waste. The best answer is usually a combination. Lock in purchased feed early when prices are known. Sell the lowest performing animals first. Improve feeding management to cut waste. Do not wait until January to make these decisions. ### Step 8: Write It Down The budget is not real until it is written. Use a spreadsheet, a notebook, or a farm management app. The format does not matter. What matters is that you can see the numbers and update them as conditions change. ## The Crop-Livestock Integration Advantage Mixed farms can do things that specialized farms cannot. The feed budget should exploit those advantages. ### Manure as a Crop Input Animals produce manure that reduces fertilizer purchases. A 1,200 pound beef cow produces about 60 pounds of manure per day. Over a 180 day feeding period, that is 10,800 pounds per animal. With 40 cows, that is 216 tons of manure available for crop ground. The nutrient value depends on bedding, storage, and application method. A ton of beef manure contains roughly 10 to 15 pounds of nitrogen, 5 to 10 pounds of phosphate, and 10 to 15 pounds of potash. At current fertilizer prices, that is worth real money. The feed budget should include a manure management plan that captures that value. ### Crop Residues as Feed Corn stalks, wheat straw, and other crop residues can extend the grazing season and reduce stored feed demand. Beef cows can graze corn stalks effectively for 60 to 90 days after harvest, picking up dropped grain and eating the more palatable parts of the residue. The feed value of crop residues is low. Corn stalks provide only about 50 percent total digestible nutrients, and protein is often below 6 percent. Dry cows in mid gestation can use this feed, but lactating cows cannot. Match the residue quality to the animal class that needs it. ### Rotation and Soil Health A mixed farm can rotate crops and pasture in ways that build soil health and reduce purchased inputs. Legumes in the rotation fix nitrogen for subsequent crops. Grazing covers crops or annual forages can add organic matter and break pest cycles. The feed budget should account for the forage value of cover crops. A cereal rye cover crop grazed in early spring can provide 30 to 60 days of grazing for stocker cattle or dry cows. That is 30 to 60 days of hay you do not have to feed. The same cover crop that protects your soil from erosion also fills a gap in your feed calendar. ### Byproduct Feeds Mixed farms often have access to byproduct feeds that specialized operations ignore. Spent brewers grains from a local brewery, soybean hulls from a processor, or cull vegetables from a nearby farm can provide low cost feed. The feed budget should include a list of these local sources and their typical availability and price. Be careful with byproducts. They vary in moisture, nutrient content, and spoilage risk. Test them before feeding large quantities. And remember that hauling water is expensive. A wet byproduct that is 70 percent moisture may not be a bargain once you account for the water you are hauling and the reduced dry matter intake. ## Common Feed Budgeting Mistakes Every farm makes these mistakes at some point. Recognizing them is the first step to avoiding them. ### Counting Bales Instead of Weighing This is the most common error and the most damaging. Bale weight varies by 20 percent or more within a single field. A budget based on assumed weights will be wrong, and the error compounds over a winter. Weigh your bales. ### Ignoring Dry Matter Feed budgets that use as fed weights are meaningless. A ton of hay at 12 percent moisture contains more feed value than a ton of hay at 18 percent moisture. Silage makes the problem worse. Always convert to dry matter before comparing supply and demand. ### Forgetting the Safety Margin Every farm loses feed to spoilage, waste, and theft by wildlife. Bunks and hay rings lose 5 to 15 percent depending on design and management. Silage faces lose 5 to 10 percent to spoilage. If your budget has zero margin, you are already short. Build in 10 to 15 percent. ### Overestimating Pasture Yield Farmers are optimists about their pastures. A pasture that looks good in June may produce far less than expected by August. Use conservative yield estimates and verify with actual grazing days. If you planned 150 grazing days and got 110, you need 40 days of feed you did not budget. ### Underestimating Animal Intake The tables provide starting points, but your animals may eat more. Cold weather increases intake by 10 to 20 percent because animals burn energy to stay warm. Mud increases energy requirements. Poor forage quality means animals eat more to meet their energy needs. Watch body condition scores and adjust. ### Waiting Too Long to Buy Feed Feed prices are lowest at harvest and highest in late winter. Farmers who wait to buy hay until January pay a premium. The feed budget should identify shortfalls in October, not February. Lock in purchases early. ### Ignoring Body Condition Scores Body condition is the best indicator of whether your feed budget is working. Cows that lose condition through the winter are telling you the budget is short. Monitor body condition scores monthly and adjust feeding rates before animals lose excessive weight. ## Decision Thresholds and When to Act A feed budget is a tool for making decisions at the right time. These thresholds help you know when to act. ### The 80 Percent Rule If your stored feed supply covers less than 80 percent of your projected demand, you need to act immediately. Waiting will only make the problem worse. Sell the lowest value animals first, lock in feed purchases, and extend grazing wherever possible. ### The 50 Percent Rule If you are below 50 percent of projected demand, you are in a crisis. You will need to make substantial herd reductions or major feed purchases. Do not delay. The longer you wait, the more weight animals lose and the lower their sale value. ### Body Condition Score Triggers For beef cows, a body condition score of 4 or less at calving is a warning that the feed budget failed. Cows that calve thin have lower conception rates, wean lighter calves, and are more likely to have health problems. If more than 10 percent of your cows are at condition score 4 or below, you need to increase feeding immediately. ### Forage Quality Triggers If your forage tests show protein below 7 percent or energy below 52 percent TDN for lactating animals, you need to supplement. Dry cows can handle lower quality feed, but lactating cows cannot. Match feed quality to animal requirements. ### Price Triggers Set a trigger price for purchased feed. If local hay prices are below your trigger, buy. If they are above, consider selling animals or extending grazing. The trigger should be based on your cost of production, not on what you hope to pay. ## Monitoring and Recordkeeping The feed budget is a living document. It needs regular updates and honest recordkeeping to stay useful. ### Monthly Reviews Set a specific day each month to review the budget. Count remaining bales, measure silage remaining, and update animal numbers. Compare actual feed use to projected use. If you are feeding faster than planned, find out why before the problem grows. ### Weigh and Record Feedouts Weigh the feed you actually deliver to each animal group. This is more work than guessing, but it gives you real data on intake. Over time, you will learn what your animals actually eat, and your budget will become more accurate. ### Track Body Condition Scores Score every animal at least four times a year: at weaning, mid gestation, at calving, and at breeding. Record the scores and look for trends. If scores are declining, your feed budget is short or your feed quality is inadequate. ### Keep Field Records Record what you planted, what you harvested, and what you got from each field. A five year history of field yields is the best predictor of next year's yield. Without records, you are guessing about your own land. ### Use Technology Wisely Spreadsheets are the minimum standard. A simple spreadsheet with columns for animal groups, months, and feed types can handle most farms. Farm management software adds features like barcode scanning and automated reports, but it only helps if you use it consistently. ### Review After Each Season At the end of the feed year, do a full review. Compare planned feed use to actual feed use. Identify where the budget was wrong and why. Write down the lessons for next year. This review is the most valuable learning tool you have. ## When to Call a Veterinarian or Extension Agent Most feed budgeting is a management task, not a medical one. But there are times when you need professional help. ### Call a Veterinarian If Call a veterinarian if animals are losing weight despite adequate feed on offer. This may indicate dental problems, internal parasites, or chronic disease. Also call if you see signs of nutritional deficiency such as poor coat condition, weakness, or unusual behavior. If multiple animals show the same symptoms, the problem may be in the feed itself. Call immediately if you suspect nitrate poisoning from drought stressed forages, prussic acid poisoning from sorghum or sudan grass, or mold toxicity from spoiled feed. These conditions can kill animals quickly. ### Call an Extension Agent If Call your local extension agent if you need help interpreting forage tests, calculating rations, or developing a grazing plan. Extension agents have access to ration balancing software and local yield data. They can also help you evaluate new feed sources or byproduct feeds. Call if you are considering a major change such as expanding the herd, shifting from hay to silage, or implementing rotational grazing. The extension office can provide enterprise budgets and research based recommendations. ### Call an Agronomist If Call an agronomist or crop consultant if you are consistently short on forage despite adequate acreage. The problem may be soil fertility, weed pressure, or harvest timing. A soil test and a crop consultation can identify the bottleneck. ## Building Resilience Into the Feed Budget The best feed budget is the one that survives a bad year. Building resilience means planning for the year you hope you do not have. ### Diversify Your Feed Sources Do not rely on a single forage type. A farm that has both hay and silage can weather a bad hay year or a failed corn crop. A farm with both pasture and annual forages can extend grazing in ways a single system cannot. ### Maintain a Feed Reserve Aim to carry over 10 to 20 percent of your annual feed needs from one year to the next. This reserve is your insurance against a dry year or a harvest failure. It costs money to carry, but it is cheaper than buying feed at panic prices. ### Build Flexibility Into the Herd Keep a portion of the herd that can be sold quickly if the feed budget falls short. Cull cows, open heifers, and stocker cattle can be marketed without harming the core breeding herd. The feed budget should identify which animals are expendable before you need to make the decision. ### Use Annual Forages as Insurance Plant a few acres of annual forages such as sorghum, sudan grass, or turnips that can be grazed or harvested if the perennial forages fail. These crops grow quickly and can fill a feed gap in 60 to 90 days. They cost money to plant, but they are cheap insurance. ### Lock in Feed Prices Early If you know you will need to buy feed, buy it at harvest time when prices are lowest. Build relationships with hay producers and grain farmers in your area. A standing order for a certain number of tons at a set price protects you from winter price spikes. ## The Economics of Feed Budgeting A feed budget is not just about having enough feed. It is about spending your feed dollars where they return the most profit. ### Feed Cost per Unit of Production Track your feed cost per pound of gain, per gallon of milk, or per calf weaned. These numbers tell you whether your feeding program is efficient. If your feed costs are above average, look for waste in the system. ### The Value of Homegrown Feed Homegrown feed is not free. It costs land, labor, seed, fertilizer, and machinery. But it is usually cheaper than purchased feed, and it is more predictable. The feed budget should compare the cost of growing feed to the cost of buying it. ### Opportunity Cost of Feed Every acre you devote to feed is an acre you cannot devote to a cash crop. The feed budget should consider whether you are better off growing feed or buying it and planting something more profitable. This calculation varies by year and by market, but it should be part of the planning process. ### Culling Decisions The feed budget often forces culling decisions. When feed is short, the question is which animals to sell. The answer is not always the oldest or the thinnest. Calculate the value of each animal's expected production against its feed cost. Sell the animals with the worst ratio. ## Case Examples These examples show how the feed budget works in practice. ### Example 1: The 40 Cow Beef Herd A farmer in the upper Midwest runs 40 beef cows on 200 acres of pasture and hay ground. The farm also grows 80 acres of corn and soybeans. The farmer feeds hay from December through March, a total of 120 days. The cows average 1,200 pounds and eat 26 pounds of dry matter per day. Total winter demand is 40 cows times 26 pounds times 120 days, which equals 124,800 pounds or 62.4 tons of dry matter. Adding 15 percent for waste and uncertainty brings the target to 71.8 tons. The farmer has 80 acres of hay ground that produces an average of 2.5 tons of dry matter per acre. That is 200 tons of dry matter, far more than the winter need. The surplus supports 30 stocker calves that graze pasture in summer and eat hay in the fall. The feed budget shows the farm has plenty of feed in an average year. But the farmer also knows that a dry year could cut hay yields in half. The budget includes a plan to sell the stockers early if hay production falls below 1.5 tons per acre. ### Example 2: The 100 Ewe Flock A farmer in the Northeast runs 100 ewes on 50 acres of pasture and hay ground. The ewes lamb in April and graze from May through October. Hay is fed from November through April, a total of 180 days. Each ewe averages 150 pounds and eats 5.5 pounds of dry matter per day in early lactation, dropping to 4 pounds when dry. Total winter demand is roughly 100 ewes times 4.5 pounds average times 180 days, which equals 81,000 pounds or 40.5 tons of dry matter. The farm produces 30 tons of dry matter in hay and relies on 15 acres of annual forages for fall grazing. The feed budget shows a potential shortfall of 10 tons. The farmer decides to plant an additional 5 acres of forage turnips and to lock in a price for 10 tons of hay from a neighbor. The budget also identifies that the ewes need higher quality feed during lactation. The farmer sorts the hay, feeding the best quality to ewes with lambs and the lower quality to dry ewes. This stretching of quality reduces purchased supplement costs by 20 percent. ### Example 3: The Diversified Dairy A dairy farmer in Wisconsin milks 60 cows and raises 40 heifers. The farm grows 100 acres of corn for silage and 80 acres of alfalfa hay. The feed budget starts at silage harvest in September. The milking herd eats 50 pounds of dry matter per day. The heifers eat 15 pounds per day. Total daily demand is 60 times 50 plus 40 times 15, which equals 3,600 pounds or 1.8 tons of dry matter per day. Over 365 days, the farm needs 657 tons of dry matter. The farm expects to harvest 100 acres of corn silage at 7 tons of dry matter per acre, which is 700 tons. The alfalfa provides another 80 acres at 3 tons of dry matter per acre, which is 240 tons. Total supply is 940 tons, giving a comfortable margin. But the farmer knows that corn silage yields vary widely. A drought year might cut yields to 4 tons per acre, reducing supply to 400 tons. The budget includes a plan to sell the 40 heifers as bred replacements if silage yields fall below 5 tons per acre. This decision is made in the budget, not in a panic in November. ## Frequently Asked Questions ### How much extra feed should I keep as a safety margin? A 10 to 15 percent margin is the minimum for a well managed farm. If your feeding system has high waste, if your forage quality is variable, or if you are in an area with frequent weather extremes, increase the margin to 20 percent. The margin is your insurance against the year you hope you do not have. ### How often should I update my feed budget? Review the budget at least monthly during the feeding season. Update it immediately after any major weather event, after harvest, and after any significant change in animal numbers. The budget is a living document, not a one time calculation. ### What is the difference between dry matter and as fed? Dry matter is the feed weight with all water removed. As fed is the weight you actually handle. A bale of hay that weighs 1,000 pounds as fed might contain 850 pounds of dry matter if the moisture is 15 percent. All feed budgeting should be done in dry matter because water has no nutritional value. ### How do I estimate pasture yield without expensive equipment? Use the grazing stick method or the pasture ruler method. These tools use pasture height and density to estimate available forage. Or use the simple method of excluding a small area from grazing and clipping the forage to measure actual growth. Your extension office can provide the specific formulas for your area. ### Should I feed my best hay to the animals that need it most? Yes. Sort your forage by quality and match it to animal requirements. Lactating animals and growing youngstock need the highest quality feed. Dry cows and ewes in early gestation can use lower quality forage. This sorting stretches your high quality feed and prevents waste. ### What do I do if I run out of feed mid winter? Act immediately. Do not wait for animals to lose condition. Buy the best quality feed you can find, even if the price is high. The cost of buying feed is almost always less than the cost of losing animals or the production losses from underfeeding. Also consider selling the lowest value animals to reduce demand. ### How do I know if my forage is good enough? Get a forage test. The lab report will show protein, energy, fiber, and mineral content. Compare those numbers to the requirements of the animals you plan to feed. If the forage does not meet requirements, you need to supplement or feed it to animals with lower requirements. ### Can I use the same feed budget for different species? You can use the same framework, but you need separate calculations for each species. Sheep, goats, cattle, and pigs have different intake rates, different nutrient requirements, and different feeding behaviors. A mixed species farm should build a separate budget line for each species, then combine them into a whole farm feed budget. ## Related Farming Guides This section will be populated with links to related farming guides on crop rotation, pasture management, livestock nutrition, and whole farm planning.
