Agriculture (crop) and livestock (ranch) at similar technological levels. The true integration of agricultural production systems

Mixed Farming

Complete Easy-to-Understand Explanation

Mixed farming is a farming system in which a farmer grows crops and rears livestock on the same farm.

For example, a farmer may cultivate paddy, maize, vegetables or pulses while also maintaining cows, buffaloes, goats, sheep or poultry. Crops provide grain, fodder and residues to the animals, while animals provide milk, eggs, meat, manure and additional income to the farm. (Wikipedia)

Crops support animals, animals support crops, and both support the farmer’s family.


1. Simple Example of Mixed Farming

Consider a farmer with two acres of land and two dairy cows.

The farmer grows:

  • Paddy on one acre

  • Maize and fodder on half an acre

  • Vegetables and pulses on the remaining land

The system works as follows:

Paddy and maize
       ↓
Grain for family or sale
       ↓
Straw and crop residues
       ↓
Feed for cattle
       ↓
Milk and manure
       ↓
Milk provides income
Manure becomes compost
       ↓
Compost returns to the crop field

This recycling relationship is the basic foundation of mixed farming. On many small farms, crop residues are important livestock feed, while animals return manure and other services to crop production. (FAOHome)


2. Main Components

A mixed farm normally contains at least two major components:

Crop component

This may include:

  • Paddy

  • Wheat

  • Maize

  • Millets

  • Pulses

  • Oilseeds

  • Vegetables

  • Fruit crops

  • Fodder crops

Livestock component

This may include:

  • Cows

  • Buffaloes

  • Goats

  • Sheep

  • Poultry

  • Ducks

  • Pigs

  • Rabbits

Some advanced mixed farms may also include:

  • Fish pond

  • Beekeeping

  • Mushroom production

  • Vermicomposting

  • Biogas production

  • Fruit trees

  • Agroforestry

  • Fodder trees

When these components are deliberately connected so that the waste from one activity becomes an input for another, the farm is often described as an integrated farming system.


3. How the Mixed-Farming Cycle Works

Step 1: Crops produce food and by-products

Crops provide:

  • Grain for household consumption

  • Produce for sale

  • Straw and stalks

  • Bran and husk

  • Green fodder

  • Damaged grains suitable for animal feed

  • Crop residues for composting

Crop residues and food-processing by-products can contribute substantially to livestock feeding in smallholder systems. However, residues such as straw and stover are often fibrous and nutritionally limited, so they normally need proper storage, processing and supplementation. (FAOHome)

Step 2: Animals convert feed into useful products

Animals convert crop residues, fodder and other feed into:

  • Milk

  • Meat

  • Eggs

  • Young animals

  • Manure

  • Urine

  • Farm income

  • Household nutrition

Step 3: Manure returns nutrients to the field

Animal manure can be:

  • Composted

  • Vermicomposted

  • Used in a biogas plant

  • Converted into liquid manure

  • Applied after proper decomposition

The manure supports soil organic matter and nutrient recycling. In traditional mixed systems, animals have also contributed farm power and household financial security. (FAOHome)

Step 4: Farm waste is recycled

Instead of treating every residue as waste:

  • Straw becomes animal feed.

  • Animal dung becomes compost.

  • Biogas slurry becomes manure.

  • Vegetable waste becomes compost or suitable livestock feed.

  • Pond water may support irrigation.

  • Fodder-tree leaves feed suitable livestock.

  • Poultry litter may be composted and applied carefully.

This creates a partially closed farm cycle and can reduce the need to purchase some external inputs.


4. Mixed Farming, Mixed Cropping and Integrated Farming

These terms should not be confused.

Farming methodMeaningExample
Mixed farmingCrops and livestock on the same farmPaddy with dairy cows
Mixed croppingTwo or more crops grown togetherMaize and pigeon pea
IntercroppingCrops grown together in defined rowsTwo maize rows with one pulse row
Crop rotationDifferent crops grown one after anotherPaddy followed by green gram
Integrated farmingSeveral farm enterprises deliberately connectedCrops, dairy, fish, poultry, biogas and compost

Important difference

A farmer growing paddy and keeping two cows is practising mixed farming.

A farmer using paddy straw for cows, converting cow dung into biogas and compost, applying slurry to vegetables, and using vegetable residues for livestock is practising a more closely integrated farming system.


5. Main Types of Mixed Farming

5.1 Crop and dairy farming

The farmer grows crops and keeps cows or buffaloes.

Example

  • Paddy

  • Fodder maize

  • Napier grass

  • Two dairy animals

  • Compost unit

Resource flow

Paddy straw + green fodder
            ↓
          Cattle
            ↓
        Milk + dung
        ↓          ↓
      Income     Compost
                    ↓
                 Crop field

This is one of the most practical mixed-farming models where a reliable local milk market exists.


5.2 Crop and goat farming

The farmer grows crops while maintaining goats.

Possible components

  • Millets

  • Pulses

  • Groundnut

  • Fodder trees

  • Grasses

  • Goats

Goats can use selected grasses, leaves and browse, but they should not be expected to survive efficiently on dry crop residues alone. Their ration must match their nutritional requirements. (FAOHome)

Suitable conditions

  • Limited land

  • Availability of browse and fodder

  • Meat market access

  • Labour available for daily care


5.3 Crop and sheep farming

Sheep may be integrated with:

  • Millets

  • Pulses

  • Oilseeds

  • Grazing areas

  • Fodder crops

Sheep can graze crop stubbles after harvest, but uncontrolled grazing may damage standing crops or compact wet soil.


5.4 Crop and poultry farming

The farmer grows crops and keeps chickens.

Farm products

  • Grain

  • Vegetables

  • Eggs

  • Broiler birds

  • Poultry litter

Some grain by-products may be incorporated into balanced poultry feed, while properly composted poultry litter may be used in crop production.

Poultry waste should not be applied excessively or used without proper handling because it can be concentrated in nutrients and may create odour, fly, hygiene and runoff problems.


5.5 Crop, duck and fish farming

This system may combine:

  • Paddy or vegetables

  • Fish pond

  • Ducks

  • Pond water for irrigation

Ducks may use parts of the pond environment, while pond nutrients support biological productivity. However, stocking density, fish health, water quality, animal welfare and disease control must be carefully managed.


5.6 Paddy–fish farming

Fish are raised in specially designed paddy fields or connected trenches.

Potential outputs

  • Paddy grain

  • Straw

  • Fish

  • Additional household nutrition

  • More efficient use of field water

The field requires suitable bunds, water depth, drainage control and protection against fish escape.

Pesticide selection becomes especially important because chemicals used in the paddy field may harm fish.


5.7 Horticulture and livestock farming

Fruit trees may be combined with animals and fodder crops.

Examples

  • Mango with fodder grass and dairy

  • Coconut with pasture and cattle

  • Guava with vegetables and poultry

  • Moringa with goats

  • Citrus with suitable cover crops

Animals should not be allowed to damage young trees, roots, irrigation pipes or fruit.


6. Benefits of Mixed Farming

6.1 More than one income source

The farmer may receive income from:

  • Grain

  • Vegetables

  • Fruits

  • Milk

  • Eggs

  • Meat animals

  • Fish

  • Compost

  • Seedlings

  • Honey

When one enterprise performs poorly, another may continue to provide income.

6.2 More regular cash flow

Many field crops provide income only after harvest.

Livestock can provide:

  • Daily milk income

  • Weekly egg income

  • Periodic animal sales

  • Manure for the field

This can help meet household and farm expenses between crop harvests. Livestock products and animal sales have historically been important sources of cash and emergency financial security in mixed smallholder systems. (FAOHome)

6.3 Better use of crop residues

Materials such as:

  • Paddy straw

  • Maize stalks

  • Sorghum stover

  • Pulse haulms

  • Groundnut haulms

  • Bran

may be used as part of livestock feeding instead of being burned or discarded.

However, residues should be evaluated for:

  • Moisture

  • Mould

  • Pesticide contamination

  • Nutritional value

  • Suitable animal species

  • Supplementation requirements

6.4 Manure availability

Livestock provide manure that can be processed into:

  • Farmyard manure

  • Compost

  • Vermicompost

  • Biogas slurry

  • Enriched organic manure

6.5 Better labour utilisation

Crop work is seasonal, while livestock require daily care. Mixed farming can distribute family labour across the year.

6.6 Household food security

The family may receive:

  • Grain

  • Pulses

  • Vegetables

  • Milk

  • Eggs

  • Meat

  • Fish

6.7 Risk reduction

Mixed farming diversifies production. The farmer is less dependent on one crop, one buyer or one harvest.


7. Limitations and Challenges

Mixed farming is not automatically profitable. It requires careful management.

7.1 Daily animal care

Animals require attention every day, including:

  • Feeding

  • Watering

  • Milking

  • Shed cleaning

  • Health observation

  • Waste management

Crop activities may be delayed if labour is insufficient.

7.2 Fodder shortage

Keeping more animals than the farm can feed creates dependence on expensive purchased fodder.

The farmer must calculate:

  • Green fodder requirement

  • Dry fodder requirement

  • Concentrate requirement

  • Seasonal feed shortage

  • Feed-storage capacity

7.3 Disease risk

Livestock and poultry may experience:

  • Infectious diseases

  • Parasites

  • Mastitis

  • Foot problems

  • Nutritional deficiencies

  • Reproductive problems

Veterinary care, vaccination, deworming and biosecurity are essential.

7.4 Water requirement

Animals need clean drinking water throughout the year. Water is also required for:

  • Cleaning sheds

  • Fodder production

  • Milk handling

  • Poultry management

  • Fish ponds

7.5 Waste and odour

Poor manure management may cause:

  • Flies

  • Bad smell

  • Water contamination

  • Disease risk

  • Nutrient loss

  • Neighbour complaints

7.6 Market dependency

The farmer requires suitable markets for:

  • Milk

  • Eggs

  • Animals

  • Vegetables

  • Fish

  • Grain

Perishable products need quick transportation and reliable buyers.


8. Planning a Mixed Farm

Step 1: Assess available resources

Record:

  • Total land

  • Irrigation availability

  • Soil type

  • Family labour

  • Capital

  • Existing buildings

  • Fodder availability

  • Veterinary access

  • Nearby market

  • Transport

  • Electricity

  • Crop residues produced

Step 2: Select the main enterprise

Decide which activity will be the primary income source.

Examples:

  • Crops as the main enterprise and two cows as support

  • Dairy as the main enterprise and fodder crops as support

  • Vegetables as the main enterprise with poultry

  • Fish as the main enterprise with crops and ducks

Do not begin several unfamiliar enterprises at the same time.

Step 3: Match animal numbers to feed supply

The number of animals should be based on:

  • Land available for fodder

  • Crop-residue quantity

  • Purchased-feed budget

  • Water availability

  • Labour

  • Shed space

  • Market demand

Step 4: Prepare an annual crop and fodder calendar

Plan fodder availability for every season.

PeriodPossible feed source
Rainy seasonGreen fodder, grasses, maize or sorghum fodder
Post-rainy periodLegume fodder and stored residues
WinterOats or suitable seasonal fodder
SummerIrrigated fodder, silage and stored hay

The actual crops must be selected according to the local climate and water availability.

Step 5: Arrange animal housing

A good shed requires:

  • Drainage

  • Ventilation

  • Shade

  • Clean water

  • Non-slippery floor

  • Feed trough

  • Manure collection

  • Isolation area for sick animals

  • Safe distance from household water sources

Step 6: Plan manure utilisation

Estimate:

  • Daily dung production

  • Compost-pit capacity

  • Vermicompost-bed size

  • Biogas feasibility

  • Storage duration

  • Field nutrient requirements

Do not produce more manure than the farm can safely handle.


9. One-Acre Illustrative Mixed-Farm Model

This is a sample layout, not a fixed recommendation.

ComponentIllustrative land allocation
Main food or cash crop0.50 acre
Fodder crops0.20 acre
Vegetables0.10 acre
Fish pond or fruit trees0.10 acre
Livestock shed and feed storage0.05 acre
Compost, biogas, paths and water system0.05 acre

Possible enterprises

  • One or two appropriately selected dairy animals

  • Seasonal main crop

  • Green fodder

  • Kitchen and market vegetables

  • Compost unit

  • Small pond where technically suitable

  • Fruit or fodder trees on boundaries

The actual number of animals must be determined from feed, water, labour and financial capacity—not simply from the size of the land.


10. Example: Paddy and Dairy Model

Before paddy cultivation

  1. Test the soil.

  2. Select a suitable paddy variety.

  3. Prepare the field.

  4. Apply mature compost according to need.

  5. Plan a separate fodder plot.

  6. Store previous-season dry fodder safely.

During the crop period

  1. Manage irrigation and nutrients.

  2. Grow fodder simultaneously.

  3. Keep paddy free from hazardous contamination.

  4. Record all pesticide applications.

  5. Do not feed recently sprayed crop material without confirming safety.

After harvesting

  1. Separate grain and straw.

  2. Dry straw properly.

  3. Store it away from rain and moisture.

  4. Use suitable straw as part of the animal ration.

  5. Compost unusable residues.

  6. Collect animal dung daily.

  7. Prepare compost for the next crop.

Important warning

Paddy straw alone is not a complete dairy ration. It is generally high in fibre and low in several nutrients. Animals may require suitable green fodder, protein sources, minerals and concentrates based on veterinary or animal-nutrition advice. (FAOHome)


11. Feed Management

A balanced livestock feeding system may include:

Green fodder

  • Fodder maize

  • Fodder sorghum

  • Napier hybrids

  • Cowpea

  • Lucerne where suitable

  • Oats in suitable seasons

  • Fodder trees under professional guidance

Dry fodder

  • Paddy straw

  • Wheat straw

  • Maize stover

  • Sorghum stover

  • Pulse haulms

  • Groundnut haulms

Concentrate feed

May include properly formulated combinations of:

  • Grains

  • Bran

  • Oilseed cakes

  • Mineral mixture

  • Salt

  • Commercial balanced feed

The ration should depend on:

  • Animal species

  • Body weight

  • Milk production

  • Pregnancy

  • Growth stage

  • Feed quality

  • Health condition

Random home mixtures can cause nutrient deficiency, toxicity or poor production.


12. Manure and Compost Management

Basic composting process

  1. Collect dung, urine-soaked bedding and suitable crop residues.

  2. Keep plastics, metal and veterinary waste separate.

  3. Place materials in a compost pit or heap.

  4. Maintain adequate moisture.

  5. Protect the heap from heavy rain.

  6. Turn it when required.

  7. Allow complete decomposition.

  8. Apply mature compost according to crop and soil needs.

Mature compost should normally have:

  • Dark colour

  • Earthy smell

  • Reduced heat

  • Uniform texture

  • No strong rotten smell

Biogas option

Dung can be fed into a biogas digester.

The digester may produce:

  • Gas for cooking or other suitable use

  • Nutrient-containing slurry

The slurry should be stored and applied carefully to prevent runoff and nutrient loss.


13. Animal Health and Biosecurity

Daily observation

Check:

  • Feed intake

  • Water intake

  • Milk production

  • Body condition

  • Breathing

  • Dung consistency

  • Urine

  • Walking

  • Wounds

  • Abnormal behaviour

Biosecurity measures

  • Isolate newly purchased animals.

  • Keep sick animals separate.

  • Clean feeding equipment.

  • Restrict unnecessary visitors.

  • Control rodents and flies.

  • Dispose of carcasses safely.

  • Maintain vaccination and treatment records.

  • Consult a veterinarian promptly when illness appears.

Poultry, dairy animals, goats and fish require different health-management programmes.


14. Farm Records

Maintain separate records for crops and livestock.

Crop records

  • Crop and variety

  • Sowing date

  • Seed cost

  • Fertilizer use

  • Pesticide use

  • Irrigation

  • Labour

  • Yield

  • Selling price

Livestock records

  • Animal identification

  • Purchase date

  • Breed

  • Vaccination

  • Deworming

  • Breeding

  • Milk yield

  • Feed cost

  • Veterinary cost

  • Animal sales

Whole-farm calculation

Total farm income =
Crop sales + milk sales + egg sales +
animal sales + fish sales + other income
Net farm profit =
Total farm income − total farm expenses

Do not count manure as additional profit when its value has already been included as a saving in fertilizer expenditure.


15. Daily, Weekly and Seasonal Checklist

Daily

  • Feed and water animals.

  • Check animal health.

  • Clean sheds and troughs.

  • Collect manure.

  • Check irrigation.

  • Observe crops for pests and wilting.

  • Record milk, eggs or mortality.

Weekly

  • Inspect fodder stock.

  • Check compost moisture.

  • Clean water tanks.

  • Inspect fences.

  • Review pest traps.

  • Check livestock body condition.

  • Record purchases and sales.

Monthly

  • Review feed expenditure.

  • Review veterinary records.

  • Compare production with cost.

  • Inspect shed drainage.

  • Check market prices.

  • Calculate upcoming fodder requirements.

Before each season

  • Select crops.

  • Review crop rotation.

  • Test soil where required.

  • Repair sheds and irrigation.

  • Arrange seed and fodder.

  • Prepare a labour and cash-flow plan.


16. Common Mistakes

Avoid:

  • Keeping too many animals with insufficient fodder

  • Depending only on crop straw

  • Purchasing animals without checking health and productivity

  • Mixing animals of unknown disease status immediately

  • Allowing manure to enter drinking-water sources

  • Applying fresh manure directly around young plants

  • Ignoring vaccination and deworming

  • Growing crops without considering animal-feed needs

  • Using sprayed crop residues as feed without checking safety

  • Beginning dairy, poultry, fish and vegetables simultaneously without experience

  • Failing to calculate labour requirements

  • Depending on only one milk or produce buyer

  • Expanding before maintaining records for at least one complete cycle


17. Practical Beginner Model

A beginner may start with:

  • One principal field crop

  • One fodder crop

  • A small vegetable plot

  • One or two manageable livestock animals

  • One composting unit

  • Boundary fodder or fruit trees

After gaining experience, the farmer may add:

  • Poultry

  • Vermicomposting

  • Fish pond

  • Biogas

  • Beekeeping

  • Mushroom production

Expansion should occur only after the original components are technically and financially stable.


18. Final Understanding

Mixed farming is not merely keeping animals beside a crop field. It is a planned relationship between crops, animals, farm resources, household needs and markets.

A successful mixed farm follows this cycle:

Crops → food, income and livestock feed
Livestock → milk, eggs, meat and manure
Manure → compost, biogas and soil nutrients
Healthy soil → improved crop production
Crop production → more food, feed and income

Mixed farming converts separate crop and livestock activities into one mutually supporting farm system.
