Swine Feed Budgeting for Small Farms

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Feed constitutes 60-75% of swine production costs, necessitating precise budgeting for profitability, with grow-finish pigs consuming 700-900 lbs of feed from weaning to market weight.
• Daily feed intake escalates with age, from ~1.5 lbs/day for a 40 lb pig to 6-7 lbs/day for a 250 lb pig, impacting cost acceleration in the final growth stages.
• Feed conversion ratios (FCR) for grow-finish pigs typically range from 2.6 to 3.2 lbs of feed per lb of gain, with lower FCR indicating greater feed efficiency.
• On-farm grain mixing can reduce feed costs by 15-25% compared to complete commercial feeds but requires careful ration balancing and storage to prevent nutritional deficiencies or spoilage.
• A feed budget must incorporate a 5-10% buffer for waste, environmental fluctuations in intake, and individual animal growth variations, alongside regular (4-6 week) reviews and adjustments for price shifts exceeding 10%.

Feed is the largest single expense on nearly every pig farm, often consuming 60 to 75 percent of total production costs. For small farms raising a handful of hogs for home use, direct sales, or niche markets, a poorly planned feed budget can erase profits before the animals ever reach market weight. This guide walks small-scale producers through the full process of building a realistic swine feed budget, from calculating daily intake and comparing ration options to tracking costs and adjusting for changing market conditions. It is written for farmers who raise 1 to 50 pigs per year and want practical, actionable numbers they can apply to their own operation.

At a Glance

• Feed represents 60 to 75 percent of total swine production costs on most farms.
• A standard grow-finish pig eats roughly 700 to 900 pounds of feed from weaning to market weight at 280 pounds.
• Daily feed intake climbs steadily from about 1.5 pounds per day for a 40 pound pig to 6 to 7 pounds per day for a 250 pound pig.
• Feed conversion ratio (FCR) for grow-finish pigs typically ranges from 2.6 to 3.2 pounds of feed per pound of gain.
• Complete commercial feeds cost more per ton but require no additional supplements. On-farm grain mixing costs less but demands careful balancing and storage.
• A feed budget should include a 5 to 10 percent buffer for waste, weather-related intake changes, and slower-growing animals.
• Track feed costs per pig and per pound of gain, not just total spending, to make meaningful comparisons across batches.
• Review your feed budget every 4 to 6 weeks and adjust whenever corn, soybean meal, or complete feed prices shift by more than 10 percent.

Understanding the True Cost of Feeding Pigs

Before you can build a workable feed budget, you need a clear picture of where feed costs come from and how they behave on a small farm. Many new pig keepers make the mistake of pricing feed by the bag at the local co-op without considering how much feed each animal actually consumes over its lifetime. That oversight leads to budgets that fall short by hundreds of dollars per pig.

Why Feed Costs Dominate Swine Production

Pigs are monogastric animals with simple stomachs, which means they cannot extract energy from fibrous forages the way ruminants like cattle or sheep can. They require dense, highly digestible diets built around cereal grains and protein meals. This biological reality makes pigs expensive to feed relative to grazing livestock. A beef cow on good pasture may need minimal supplemental feed for much of the year, but a pig needs a carefully formulated ration every single day from weaning to slaughter.

The cost structure of pig farming reflects this reality. When you add up breeding stock maintenance, housing, bedding, veterinary care, and labor, feed still accounts for the largest share of total expenses. On a small farm selling direct to consumers, feed costs often determine whether a batch of pigs turns a profit or loses money. Understanding this simple fact changes how you approach every feeding decision.

Fixed Costs Versus Variable Feed Costs

Your farm has fixed costs that stay roughly the same regardless of how many pigs you raise. These include barn payments, fencing, waterers, feeders, and basic equipment. Variable costs change with the number of animals and include feed, bedding, veterinary supplies, and marketing expenses. Feed is the biggest variable cost on almost every pig farm, which means it is also the area where you have the most control.

A common mistake among small farmers is treating feed as a fixed expense. They buy the same feed every month without tracking how much each pig actually consumes. This approach hides inefficiencies and makes it impossible to identify problems early. A proper feed budget treats feed as the flexible, controllable cost it really is.

How Pig Biology Drives Feed Consumption

Pigs do not eat a flat amount of feed every day. Their intake follows a predictable curve that rises steadily as they grow. A weaned pig at 20 to 30 pounds might eat only 1 to 1.5 pounds of feed per day. That same pig at 150 pounds will consume 4 to 5 pounds daily. By the time it reaches 250 to 280 pounds, it may eat 6 to 7 pounds per day.

This growth curve matters for budgeting because it means your feed costs accelerate in the final weeks before market. A pig in its last month of feeding consumes nearly as much feed as it did in the entire first two months after weaning. Many small farmers underestimate this late-stage intake and run out of feed budget right when their pigs are eating the most.

Building Your Feed Budget Step by Step

Creating a reliable feed budget requires working through a series of calculations. The process is straightforward, but each step depends on accurate inputs. Take the time to gather real numbers from your own farm rather than relying on generic estimates.

Step 1: Define Your Production Goals

Start by writing down exactly what you are trying to accomplish with your pig operation. Are you raising two hogs per year for your family's freezer? Are you selling 20 pigs annually to local customers? Are you breeding your own gilts and raising the offspring to market weight? Each scenario produces a different feed budget.

Your production goals should include target market weight, number of pigs per batch, number of batches per year, and whether you are raising pigs from weaning or farrowing your own. A farm that buys weaned pigs at 25 pounds and feeds them to 280 pounds has a very different feed budget than a farrow-to-finish operation that must also feed breeding stock.

Write these numbers down and keep them visible. Every subsequent calculation flows from these basic decisions.

Step 2: Estimate Total Feed Per Pig

The most important number in your entire feed budget is total feed consumption per pig from arrival to market. You can calculate this using expected daily gain and feed conversion ratio, or you can use published intake tables for your target weight range.

For a grow-finish pig from 50 pounds to 280 pounds, plan on approximately 700 to 900 pounds of feed per pig. This range accounts for differences in genetics, feed quality, housing, and management. Pigs started at weaning at 20 to 25 pounds will need additional feed for the nursery phase, typically 50 to 75 pounds per pig.

Here is a simple way to estimate total feed per pig:

1. Determine your target market weight in pounds.
2. Subtract the starting weight of the pig.
3. Divide by your expected average daily gain, typically 1.6 to 1.9 pounds per day for well-managed grow-finish pigs.
4. Multiply the number of days by the average daily feed intake for that weight range.

For a pig going from 50 to 280 pounds with an average daily gain of 1.8 pounds, the feeding period is about 128 days. Average daily feed intake over that period might be 5.5 pounds per day, giving roughly 700 pounds of total feed. Add a 10 percent buffer for waste and variation, and you get a planning figure of about 770 pounds per pig.

Step 3: Choose Your Feed Strategy

Small farmers typically choose among three feed strategies: complete commercial feeds, on-farm grain mixing with a supplement, or a hybrid approach. Each has different cost structures, labor requirements, and risks.

Complete commercial feeds come ready to use from a feed mill or co-op. They are formulated to meet all nutritional requirements for each life stage and require no additional mixing or supplementation. They are the most expensive option per ton but the simplest to manage. For farms raising fewer than 10 pigs per year, the labor savings and nutritional reliability often justify the higher cost.

On-farm mixing involves buying whole or ground corn and a protein supplement, then combining them according to a ration formula. This approach can cut feed costs by 15 to 25 percent compared to complete feeds, but it requires accurate weighing, proper grinding, and careful storage. Mistakes in mixing can lead to poor growth or nutritional deficiencies that cost more than the savings.

The hybrid approach uses complete feed for nursery and early grower stages, then switches to on-farm mixed rations for the finishing phase. This strategy captures some cost savings while reducing nutritional risk during the most sensitive growth periods.

Step 4: Calculate Feed Cost Per Pig

Once you know your total feed per pig and your feed cost per ton, you can calculate feed cost per pig. The math is simple: divide feed cost per ton by 2,000 to get cost per pound, then multiply by total pounds of feed per pig.

For example, if complete feed costs $420 per ton, that is 21 cents per pound. A pig consuming 770 pounds of feed would have a feed cost of about $162. If you mix your own feed at $300 per ton, or 15 cents per pound, the same 770 pounds would cost about $116. That $46 difference per pig adds up quickly across a batch of 20 pigs.

Remember that your feed cost per ton should include delivery charges, storage losses, and any grinding or mixing fees. A feed that looks cheap at the mill can become expensive by the time it reaches the feeder.

Step 5: Add Feed for Breeding Stock

If you keep sows or a boar on your farm, you must budget for their feed separately. A mature sow eats 4 to 6 pounds of feed per day when not lactating and 12 to 15 pounds per day during lactation. A mature boar eats 5 to 6 pounds per day of a maintenance ration.

For a sow producing two litters per year, annual feed consumption typically runs 1,800 to 2,200 pounds. This feed does not directly produce pork but is essential to the breeding herd. Small farms that buy weaned pigs avoid this cost entirely, which is one reason buying feeder pigs is often more profitable for very small operations.

Step 6: Build in Your Buffer

Every feed budget needs a margin for error. Pigs eat more in cold weather, less during heat waves, and some individuals simply eat more than the average. Feed spills, spoiled feed, and feeder adjustments all add to total consumption. A 5 to 10 percent buffer is the minimum for a realistic budget.

This buffer also protects you against price increases. If you budget feed at current prices and corn jumps 20 percent before your pigs reach market, the buffer gives you room to absorb the increase without coming up short.

Step 7: Multiply by Your Herd Size

The final step is multiplying per-pig costs by your total number of pigs. This gives you the total feed budget for the batch or the year. Keep this number separate from your other production costs so you can track feed spending against your plan.

Comparing Feed Options for Small Farms

The choice between complete feeds, on-farm mixing, and hybrid approaches deserves careful consideration. Each option has real tradeoffs that go beyond simple cost per ton.

Complete Commercial Feeds

Complete feeds are the safest choice for most small farms. They come in formulations for each life stage, including starter, grower, and finisher rations. The feed mill has already balanced the amino acids, minerals, and vitamins to meet established nutritional standards. You do not need to worry about mixing errors or nutrient deficiencies.

The main drawback is cost. Complete feeds typically cost $100 to $150 more per ton than the ingredients for an equivalent on-farm ration. For a farm raising 10 pigs per year, that difference might total $400 to $600 annually. For many small farmers, that premium is worth the convenience and reliability.

Complete feeds also offer consistency. Every bag from a reputable mill contains the same formulation. This consistency translates into predictable growth rates and feed conversion, which makes budgeting easier.

On-Farm Grain Mixing

Mixing your own feed can save real money, but it demands more from you as a manager. You need a reliable source of corn or other grain, a protein supplement such as soybean meal, and the equipment to grind and mix accurately. You also need to understand basic swine nutrition to avoid costly mistakes.

The biggest risk in on-farm mixing is error. A ration that is low in lysine or other essential amino acids will slow growth and increase feed conversion, wiping out any cost savings. A ration that is too high in certain minerals can cause health problems. Small farmers who mix their own feed should have their rations checked by a swine nutritionist or extension specialist at least once.

Storage is another consideration. Whole grain can be stored for months under proper conditions, but ground feed spoils quickly, especially in warm humid weather. Mix only what you will use in 2 to 3 weeks to avoid waste.

Hybrid Feeding Programs

Many successful small farms use a hybrid approach. They feed complete starter and early grower rations to young pigs, then switch to on-farm mixed rations for the finishing phase. This strategy captures cost savings when pigs are eating the most while protecting the most vulnerable growth stages.

The hybrid approach also reduces risk. If your on-farm mixing is slightly off, the impact on a 200 pound pig is less severe than on a 40 pound pig. Young pigs have smaller margins for nutritional error and less body fat to buffer against deficiencies.

Buying Feed in Bulk Versus by the Bag

Small farms often pay a premium for bagged feed. Bulk feed delivered by a truck is substantially cheaper per ton but requires storage bins and a minimum order quantity. If you have the storage capacity and can coordinate deliveries with other local farms, bulk buying can cut feed costs by 10 to 20 percent.

Some co-ops allow small farmers to pool orders. If you know other pig keepers in your area, consider combining orders to reach bulk minimums. This approach works especially well for complete feeds that you can store in clean, rodent-proof containers for several weeks.

Nutritional Requirements by Life Stage

Understanding what pigs need at each stage helps you choose the right feed and avoid wasting money on inappropriate rations. Feeding a finisher ration to young pigs or a starter ration to market hogs is both wasteful and harmful.

Nursery Phase (Weaning to 50 Pounds)

Weaned pigs have immature digestive systems and high nutritional requirements. They need highly digestible feed with higher protein and energy levels than older pigs. Commercial starter feeds are formulated specifically for this stage and typically contain 18 to 22 percent protein.

Nursery pigs eat relatively small amounts, so the total cost of this phase is modest, usually 50 to 75 pounds of feed per pig. Do not cut corners here. Poor nutrition during the nursery phase can permanently reduce growth potential and increase the risk of disease.

Grower Phase (50 to 120 Pounds)

Once pigs reach about 50 pounds, they can handle less expensive feeds with slightly lower protein levels. Grower rations typically contain 16 to 18 percent protein. Pigs in this phase are growing efficiently, converting feed to gain at rates of 2.5 to 2.8 pounds of feed per pound of gain.

This phase lasts roughly 40 to 50 days for a well-managed pig. Total feed consumption runs about 200 to 250 pounds per pig.

Finisher Phase (120 to 280 Pounds)

The finishing phase is where most of your feed dollars go. Pigs eat the most during this period, and feed conversion becomes less efficient as they approach market weight. Finisher rations typically contain 13 to 15 percent protein.

A pig going from 120 to 280 pounds will consume about 450 to 550 pounds of feed. This phase accounts for roughly 60 percent of total feed costs for a grow-finish pig. It is also where on-farm mixing can generate the biggest savings, because the nutritional margins are slightly more forgiving.

Breeding Stock

Sows and boars have distinct nutritional needs that change throughout the reproductive cycle. Gestating sows need a maintenance ration of about 4 to 6 pounds per day, while lactating sows need 12 to 15 pounds of a higher-energy ration. Boars need a balanced maintenance ration year-round.

Breeding stock feed is a fixed cost that does not directly produce marketable pork. Keep these animals as efficient as possible by avoiding overfeeding and maintaining proper body condition.

Feed Conversion Ratio and What It Means for Your Budget

Feed conversion ratio, or FCR, is the pounds of feed required to produce one pound of live weight gain. A pig with an FCR of 2.8 eats 2.8 pounds of feed for every pound it gains. Lower is better.

Typical FCR Ranges

Grow-finish pigs in well-managed operations typically achieve FCRs between 2.6 and 3.2. Genetics, feed quality, health status, and environmental conditions all influence this number. Pigs with poor genetics, chronic disease, or uncomfortable housing will have higher FCRs and higher feed costs per pound of gain.

For budgeting purposes, use an FCR of 2.8 to 3.0 for grow-finish pigs. If your pigs consistently achieve better than 2.6, you have an excellent operation. If they run above 3.2, investigate the causes before expanding your herd.

Calculating Feed Cost Per Pound of Gain

Feed cost per pound of gain combines FCR with feed price. Multiply FCR by feed cost per pound to get this number. For example, a pig with an FCR of 2.9 eating feed that costs 18 cents per pound has a feed cost per pound of gain of about 52 cents.

This number is the most useful metric for comparing feeding strategies. It accounts for both feed efficiency and feed price, giving you a single figure to track over time. A cheaper feed that produces worse conversion may cost more per pound of gain than a premium feed.

Improving Your FCR

Several management practices improve feed conversion without changing your feed formulation. Keep pigs comfortable with proper ventilation and temperature control. Provide clean water at all times. Reduce stress from overcrowding, mixing unfamiliar pigs, and excessive handling. Maintain a consistent feeding schedule.

Health is the biggest factor in feed conversion. Pigs fighting off disease divert energy to their immune systems instead of growth. Work with your veterinarian to keep your herd healthy and address any signs of illness promptly.

Managing Feed Waste

Feed waste is a silent budget killer on many small farms. Losses of 5 to 15 percent are common, and some operations waste 20 percent or more without realizing it. Reducing waste is often the cheapest way to lower your feed budget.

Sources of Feed Waste

Feeder design is the primary source of waste. Poorly adjusted feeders allow pigs to root feed out onto the floor, where it gets trampled and soiled. Feeders with damaged adjustment mechanisms or missing parts can waste significant amounts of feed.

Storage problems also contribute to waste. Feed stored in open containers attracts rodents and birds. Moisture causes mold and spoilage. Feed that has gone stale or rancid will be refused by pigs, and you will need to discard it.

Overfeeding is another form of waste. Pigs should have access to feed throughout the day, but feeders should be adjusted so that feed flows only as pigs eat. Feed that sits in the trough for hours becomes stale and less palatable.

Measuring and Reducing Waste

The simplest way to measure waste is to track feed disappearance against expected consumption. If you know your pigs should eat 700 pounds of feed per pig and you are going through 800 pounds, you have a waste problem.

Regular feeder adjustment is the most effective waste reduction strategy. Check feeders daily and adjust the flow to match the pigs' consumption. Clean up spilled feed immediately and fix any feeder damage promptly.

Invest in quality feeders designed for pigs. A good feeder pays for itself through reduced waste within a single batch of pigs. Look for feeders with adjustable flow, sturdy construction, and designs that minimize rooting and spillage.

Recordkeeping for Feed Budgets

Accurate records are essential for managing feed costs. You cannot improve what you do not measure. A simple recordkeeping system tailored to your operation will tell you whether you are on budget and where problems are emerging.

What to Track

At minimum, track the following for each batch of pigs:

1. Number of pigs and their starting weights
2. Date of arrival or weaning
3. Feed purchases with dates, quantities, and costs
4. Feed deliveries to each pen or group
5. Pig weights at regular intervals, ideally every 2 to 4 weeks
6. Feed refusals, spoilage, and waste estimates
7. Health problems and treatments
8. Final market weights and sale prices

This information allows you to calculate feed per pig, FCR, cost per pound of gain, and total feed cost per pig. Compare these numbers across batches to identify trends and improvement opportunities.

Recordkeeping Tools

A simple notebook or spreadsheet is sufficient for most small farms. If you prefer digital tools, a basic spreadsheet program works well. Several farm management apps include feed tracking features, but they are not necessary for operations under 50 pigs.

The key is consistency. Record feed purchases when they happen, not at the end of the month. Weigh pigs on a regular schedule. Update your budget calculations at least monthly.

Using Records to Adjust Your Budget

Your records should drive your budget decisions. If your current batch is consuming feed faster than projected, adjust your remaining feed orders accordingly. If feed prices have risen since you set your budget, recalculate your break-even market weight and sale price.

Review your feed budget every 4 to 6 weeks. This interval is short enough to catch problems early but long enough to see meaningful trends. Adjust your plan whenever actual performance deviates from projections by more than 10 percent.

Common Feed Budgeting Mistakes

Small farmers tend to repeat the same set of feed budgeting errors. Recognizing these mistakes in your own operation is the first step to correcting them.

Underestimating Total Feed Consumption

The most common mistake is planning for less feed than pigs actually need. New pig keepers often use published averages without accounting for their specific genetics, management, and environment. The result is an unrealistic budget that requires mid-batch adjustments.

Always add a 10 percent buffer to your feed estimates. If you are unsure about your pigs' genetics or your management level, use 15 percent. It is better to have a small surplus of feed than to run short in the final weeks before market.

Ignoring Price Volatility

Feed prices fluctuate with commodity markets. Corn and soybean meal prices can swing 20 to 30 percent within a few months. A budget based on current prices without any contingency will fail when prices rise.

Build price flexibility into your budget by using conservative price estimates and keeping a reserve for unexpected increases. If you have storage capacity, consider buying feed when prices are low.

Feeding All Pigs the Same Ration

Pigs at different stages have different nutritional needs. Feeding a single ration to all pigs wastes money on expensive ingredients for pigs that do not need them or deprives young pigs of nutrients they require. Use phase feeding to match rations to each group's needs.

Overlooking Water

Water is the most essential nutrient and the cheapest feed ingredient. Pigs need clean, fresh water at all times. Inadequate water intake reduces feed consumption and growth, effectively raising your feed cost per pound of gain.

Check waterers daily, especially during hot weather. A pig can drink 2 to 3 gallons of water per day, and lactating sows need even more.

Neglecting Health and Biosecurity

Disease outbreaks can destroy your feed budget. Sick pigs eat less, convert feed poorly, and may die before reaching market. A single disease outbreak can cost more than all the money you saved on feed for an entire year.

Work with your veterinarian to establish a herd health plan. Follow basic biosecurity protocols to prevent disease introduction. Quarantine new animals before mixing them with your herd.

Decision Thresholds for Your Feed Budget

Knowing when to adjust your feeding strategy is as important as creating the budget in the first place. Use these thresholds as triggers for reevaluating your approach.

When Feed Prices Rise More Than 10 Percent

A sustained price increase of 10 percent or more warrants a review of your feed strategy. Consider switching to a cheaper feed option, adjusting your target market weight, or reducing the number of pigs in your current batch.

If you mix your own feed, compare current ingredient costs against complete feed prices. The gap between these options changes as commodity prices move.

When FCR Exceeds 3.2

An FCR above 3.2 for grow-finish pigs indicates a problem. Investigate feed quality, health status, environmental conditions, and genetics. Work with your veterinarian or extension agent to identify the cause before starting another batch.

Do not simply accept a high FCR as normal. Every 0.1 increase in FCR adds roughly 15 to 20 pounds of feed per pig, which can cost $3 to $5 per pig at current prices.

When Feed Cost Per Pound of Gain Exceeds Your Break-Even

Calculate your break-even feed cost per pound of gain by dividing your expected sale price per pound by your expected margin. If your actual feed cost per pound of gain exceeds this number, you are losing money on every pound of gain.

This situation calls for immediate action. Reduce waste, improve feed conversion, or consider marketing pigs at a lighter weight where feed efficiency is better.

When Market Prices Drop

Falling pork prices change the economics of feeding to heavier weights. Pigs fed to 280 pounds need more feed per pound of gain than pigs marketed at 240 pounds. If market prices are weak, consider selling at a lighter weight to avoid the less efficient finishing phase.

Use your records to calculate the marginal cost of adding another 10 pounds of gain. If that cost exceeds the expected market price, it is time to sell.

When to Call a Veterinarian or Extension Agent

Your feed budget and your herd health are closely connected. Several situations call for professional advice beyond your own experience.

Sudden Changes in Feed Intake

If your pigs suddenly stop eating or dramatically reduce their intake, contact your veterinarian. Reduced feed intake is often the first sign of disease, and early intervention can prevent a costly outbreak.

A drop in feed intake across a group of pigs is more concerning than a single pig going off feed. It suggests a problem affecting the whole group, such as contaminated feed, water failure, or an infectious disease.

Poor Growth Despite Adequate Feed

If your pigs are eating well but not gaining weight, you need professional help. This situation can indicate a feed formulation problem, a parasite burden, or a chronic disease. Your veterinarian can run diagnostic tests to identify the cause.

Your extension agent can help you evaluate your feed formulation and compare it against established nutritional requirements. They can also connect you with swine nutrition specialists if needed.

Feed Quality Concerns

If you suspect your feed is contaminated, moldy, or otherwise unsuitable, stop feeding it immediately and contact your veterinarian or extension agent. Contaminated feed can cause acute illness or chronic poor performance.

Keep samples of any suspect feed for testing. Your veterinarian or extension agent can help you arrange laboratory analysis.

Before Major Changes to Your Feeding Program

Before switching from complete feeds to on-farm mixing, or making any other major change to your feeding program, consult with your extension agent or a swine nutritionist. They can review your planned rations and help you avoid costly mistakes.

This consultation is especially important if you are new to pig farming or have limited experience with feed formulation. The cost of a professional review is small compared to the potential losses from a poorly balanced ration.

Seasonal Considerations for Feed Budgets

Pig feed consumption and feed costs vary by season, and a good budget accounts for these patterns.

Cold Weather Feeding

Pigs increase their feed intake in cold weather to maintain body temperature. A pig housed outdoors in winter may eat 10 to 15 percent more feed than the same pig in mild weather. This increase directly raises your feed costs.

Provide adequate bedding and windbreaks to help pigs stay warm without consuming extra feed. Well-bedded, sheltered pigs use less energy for warmth and convert feed more efficiently.

Hot Weather Feeding

Heat stress reduces feed intake, which slows growth and extends the feeding period. Pigs that eat less take longer to reach market weight, increasing total feed costs even though daily intake is lower.

Provide shade, ventilation, and plenty of clean water during hot weather. Consider feeding during cooler parts of the day to encourage intake.

Seasonal Feed Prices

Commodity feed prices follow seasonal patterns. Corn prices often rise in the spring and fall after harvest. Soybean meal prices can spike during planting or harvest disruptions. Knowing these patterns helps you time feed purchases.

If you have storage capacity, buying feed when prices are seasonally low can reduce your annual feed costs. Consult your extension agent or local feed dealer for price forecasts in your area.

Scaling Your Feed Budget as Your Farm Grows

As your operation expands, your feed budgeting approach will need to evolve. What works for 5 pigs may not work for 50.

The Transition from Hobby to Business

When you start selling pork commercially, your feed budget becomes a business tool rather than a household expense. You need accurate cost tracking, break-even analysis, and profit projections. Your records must be detailed enough to support business decisions.

Consider working with a farm business advisor or extension specialist to develop a more sophisticated budgeting system as your operation grows.

Volume Discounts and Bulk Buying

Larger operations can negotiate better feed prices through volume discounts and bulk purchases. A farm buying 10 tons of feed per year has more negotiating power than one buying 2 tons.

As your volume grows, revisit your feed sourcing regularly. Compare prices from multiple suppliers and consider cooperative buying arrangements with neighboring farms.

Adding Breeding Stock

Farrowing your own pigs adds feed costs for breeding stock but can reduce overall feed costs per pig if done efficiently. The added complexity of managing sows and litters requires more management skill and a more detailed feed budget.

Only add breeding stock when you have mastered grow-finish feeding and have the facilities and knowledge to manage a breeding herd.

Building a Year-Round Feed Plan

A year-round feed plan helps you manage costs and avoid last-minute purchases at unfavorable prices.

Estimate Annual Feed Requirements

Multiply your per-pig feed estimate by your total annual pig production. Add feed for breeding stock if applicable. This gives you your annual feed requirement in pounds or tons.

For example, a farm raising 20 grow-finish pigs per year at 770 pounds per pig needs about 15,400 pounds of feed annually, or roughly 7.7 tons. Add 10 percent for buffer and waste, and the planning figure is about 8.5 tons.

Plan Your Purchasing Schedule

Decide whether you will buy feed monthly, quarterly, or in bulk batches. Consider your storage capacity, cash flow, and price outlook. A monthly purchasing schedule offers flexibility but may mean paying higher prices. Bulk buying locks in prices but requires more capital and storage.

Many small farms find a quarterly purchasing schedule works well. It balances price stability with cash flow and storage constraints.

Review and Adjust Quarterly

Every quarter, compare your actual feed consumption and costs against your plan. Adjust your remaining purchases to reflect what you have learned. If your pigs are eating more than projected, order more feed. If prices have risen, adjust your budget or consider alternative feed sources.

This quarterly review keeps your feed budget aligned with reality without requiring constant monitoring.

Frequently Asked Questions

How much feed does one pig need from weaning to market?

A grow-finish pig raised from about 50 pounds to market weight at 280 pounds typically consumes 700 to 900 pounds of feed. Pigs started at weaning at 20 to 25 pounds need an additional 50 to 75 pounds of starter feed. The exact amount depends on genetics, feed quality, health, and management. Plan on 770 to 850 pounds per pig to allow for normal variation and waste.

What is a good feed conversion ratio for small farm pigs?

A feed conversion ratio between 2.6 and 3.0 is typical for well-managed grow-finish pigs. This means the pig eats 2.6 to 3.0 pounds of feed for each pound of weight gained. Ratios above 3.2 indicate problems with feed quality, health, genetics, or management that should be investigated. Small farms with good genetics and management can achieve FCRs at the lower end of this range.

Is it cheaper to mix your own pig feed or buy complete feed?

Mixing your own feed can save 15 to 25 percent on feed costs, but only if you do it accurately and avoid waste. The savings come from buying raw ingredients rather than paying for the milling and formulation included in complete feed prices. However, mixing errors, spoilage, and the cost of equipment can erase these savings. For farms raising fewer than 10 pigs per year, the convenience and reliability of complete feed often outweigh the cost difference.

How much should I budget for feed per pig?

At current feed prices, plan on $150 to $200 per grow-finish pig for feed from 50 pounds to market weight. This range assumes feed costs of 18 to 24 cents per pound and consumption of 770 to 850 pounds per pig. Pigs started at weaning will cost more, and farms raising their own breeding stock must add feed costs for sows and boars. Your actual costs depend on your feed strategy and local prices.

Should I feed my pigs a different ration at different ages?

Yes. Pigs have different nutritional requirements at each life stage. Nursery pigs need highly digestible feed with 18 to 22 percent protein. Grower pigs need 16 to 18 percent protein. Finisher pigs need 13 to 15 percent protein. Feeding a single ration to all ages either wastes money on unnecessary nutrients or deprives pigs of what they need. Phase feeding matches the ration to the pig's current needs for the best feed efficiency.

What is the biggest mistake small farmers make with feed budgeting?

The biggest mistake is underestimating total feed consumption. Many new pig keepers plan for 500 to 600 pounds of feed per pig and run out of feed or money before their pigs reach market weight. Always build a 10 percent buffer into your feed estimates and track actual consumption carefully. The second biggest mistake is ignoring feed waste, which can easily reach 10 to 15 percent of total feed purchased.

How often should I weigh my pigs to track feed efficiency?

Weigh your pigs at least every 2 to 4 weeks during the grow-finish period. This frequency lets you calculate average daily gain and feed conversion with reasonable accuracy. Weighing more often gives better data but adds stress to the pigs and labor to your routine. A consistent schedule of monthly weights is sufficient for most small farms.

When should I adjust my feed budget during a batch of pigs?

Review your feed budget every 4 to 6 weeks throughout the feeding period. Adjust your plan whenever actual feed consumption deviates from projections by more than 10 percent, when feed prices change by more than 10 percent, or when you notice health problems affecting feed intake. Early adjustments prevent running out of feed or money at the end of the batch.
