Emu Farming: Production Systems, Nutrition, and Marketing

Emu farming (Dromaius novaehollandiae) is a livestock enterprise focused on producing meat, oil, leather, feathers, and eggs. This article provides practical guidance on housing, incubation, chick rearing, grow-out nutrition, breeding management, disease prevention, and product marketing for prospective and current emu farmers. The information is drawn from official poultry production resources, veterinary references, and peer-reviewed studies on emu genetics, nutrition, and health.

At a Glance

Production Parameter Typical Range Key Management Consideration
Incubation period 48 to 52 days Temperature 36.0 to 37.0 degrees Celsius, humidity 25 to 40 percent, turn eggs 4 to 6 times daily
Chick rearing (brooding) 0 to 8 weeks Maintain brooder temperature at 32 to 35 degrees Celsius for first week, reduce by 2 to 3 degrees per week
Grow-out period 8 to 14 months Provide balanced ration with 18 to 20 percent crude protein, monitor weight gain monthly
Age at first egg 18 to 24 months Provide nesting areas with soft substrate, collect eggs twice daily
Slaughter age (meat) 12 to 18 months Target live weight 40 to 55 kilograms, process at USDA-inspected facility if selling meat
Oil yield per bird 4 to 8 liters Harvest from fat pad at processing, render at low temperature (60 to 70 degrees Celsius)

Production Systems and Housing

Emus require secure fencing, shelter from extreme weather, and adequate space for exercise. Housing design affects bird welfare, growth rates, and disease risk.

Fencing and Enclosure Design

Adult emus can reach 1.5 to 1.8 meters in height and run at speeds up to 50 kilometers per hour. Perimeter fencing should be at least 1.8 meters tall, constructed from woven wire or chain link with openings no larger than 10 by 10 centimeters to prevent head entrapment. Top rails or angled extensions help prevent escape. Internal paddock fencing can be lower (1.2 to 1.5 meters) for separating breeding pairs or age groups.

Space recommendations per bird:

  • Breeding pairs: 0.1 to 0.2 hectares per pair
  • Grow-out birds (3 to 14 months): 50 to 100 square meters per bird
  • Chicks (0 to 8 weeks): 1 to 2 square meters per chick in brooder

Shelter Requirements

Emus tolerate a wide temperature range but require shade in summer and windbreaks in winter. Open-sided sheds or pole barns oriented away from prevailing winds provide adequate protection. Flooring should be well-drained sand, gravel, or concrete with deep litter (straw or wood shavings). Wet or muddy conditions increase risk of foot infections and feather damage.

Biosecurity Measures

The USDA Animal and Plant Health Inspection Service provides guidelines for avian disease prevention (https://www.aphis.usda.gov/livestock-poultry-disease/avian). Implement these biosecurity practices:

  • Restrict visitor access to bird areas
  • Use dedicated footwear and clothing for each barn or paddock
  • Quarantine new birds for 30 days before introducing to the flock
  • Clean and disinfect equipment between groups
  • Control rodents and wild birds that may carry pathogens

Incubation and Hatchery Management

Emu eggs are large (500 to 700 grams) with a thick, dark green shell. Successful incubation requires precise temperature and humidity control.

Egg Collection and Storage

Collect eggs twice daily during the breeding season (typically October to March in the Northern Hemisphere). Clean eggs with a dry cloth, do not wash with water as this removes the protective cuticle. Store eggs at 13 to 16 degrees Celsius with 70 to 80 percent relative humidity for no more than 7 days before setting. Turn stored eggs once daily to prevent embryo adhesion.

Incubation Parameters

Set eggs in forced-air incubators with automatic turning. Maintain these conditions:

  • Temperature: 36.0 to 37.0 degrees Celsius (dry bulb)
  • Humidity: 25 to 40 percent relative humidity for first 45 days
  • Turning: 4 to 6 times daily at 90 degrees rotation
  • Candling: At day 14 and day 35 to remove infertile or dead embryos

During the last 3 to 5 days of incubation (days 48 to 52), increase humidity to 50 to 60 percent and stop turning. Eggs should be placed on their sides in hatching trays with adequate spacing.

Hatch Assistance

Emu chicks may take 24 to 48 hours to fully emerge after pipping. Do not assist unless the chick has pipped but made no progress for 24 hours. Assisted hatching increases risk of infection and should be performed only by experienced personnel using sterile technique.

Chick Rearing

The first 8 weeks are the most critical period for emu chick survival. Mortality during this phase can reach 20 to 30 percent on farms with suboptimal management.

Brooder Setup

Use a brooder with a heat source (infrared lamp or brooder stove) that maintains floor temperature at 32 to 35 degrees Celsius during the first week. Reduce temperature by 2 to 3 degrees per week until ambient temperature reaches 21 to 24 degrees Celsius. Provide a draft-free environment with good ventilation.

Chicks need:

  • Clean water in shallow, non-spill containers
  • Starter feed (22 to 24 percent crude protein) in shallow trays
  • Non-slip flooring (rubber matting or paper towels) to prevent leg splay
  • 24 hours of light for the first 3 days, then reduce to 16 hours light per day

Feeding and Nutrition for Chicks

Emu chicks have high protein requirements for rapid growth. Feed a commercial ratite starter or a formulated ration containing:

  • Crude protein: 22 to 24 percent
  • Lysine: 1.2 to 1.4 percent
  • Methionine plus cysteine: 0.8 to 1.0 percent
  • Calcium: 1.0 to 1.2 percent
  • Available phosphorus: 0.5 to 0.6 percent

Offer feed ad libitum for the first 8 weeks. Monitor feed intake daily, a healthy chick consumes 30 to 50 grams of feed per day by week 4.

Common Chick Health Problems

Leg deformities (splayed legs, rotated tibiotarsal joints) are common in emu chicks. Causes include slippery flooring, nutritional imbalances, and rapid growth. Prevent by providing non-slip surfaces and balanced rations. If leg problems appear, consult a veterinarian experienced with ratites.

Respiratory infections can occur if brooder ventilation is inadequate. Signs include nasal discharge, open-mouth breathing, and lethargy. The Merck Veterinary Manual provides guidance on poultry respiratory diseases (https://www.merckvetmanual.com/poultry).

Grow-Out Nutrition and Feeding

From 8 weeks to slaughter age (12 to 18 months), emus require a balanced diet that supports muscle growth and fat deposition for oil production.

Feed Formulation

Grower rations should contain:

  • Crude protein: 18 to 20 percent (weeks 8 to 24), then 14 to 16 percent (after 24 weeks)
  • Energy: 2,600 to 2,800 kcal metabolizable energy per kilogram
  • Fiber: 6 to 10 percent (emus utilize fiber better than chickens)
  • Calcium: 0.8 to 1.0 percent
  • Available phosphorus: 0.4 to 0.5 percent

Feed can be pelleted or in mash form. Emus prefer larger particle sizes, crumbles or pellets of 4 to 6 millimeters are suitable.

Pasture and Forage

Emus can consume pasture grasses and legumes, which reduce feed costs and provide exercise. Good pasture species include alfalfa, clover, ryegrass, and orchard grass. Rotate paddocks to prevent overgrazing and parasite buildup. During winter or dry seasons, supplement with hay or silage.

Water Requirements

Provide clean, fresh water at all times. Adult emus drink 2 to 4 liters per day depending on temperature and feed intake. Water troughs should be cleaned weekly to prevent algae growth and bacterial contamination.

Monitoring Growth

Weigh a sample of birds (10 to 20 percent of the flock) monthly to track growth rates. Target weights:

  • 8 weeks: 1.5 to 2.5 kilograms
  • 6 months: 15 to 20 kilograms
  • 12 months: 30 to 40 kilograms
  • 18 months: 40 to 55 kilograms

If growth is below targets, evaluate feed quality, stocking density, and health status.

Breeding Management

Emus reach sexual maturity at 18 to 24 months. Breeding pairs or trios (one male with two females) are common. The male incubates eggs and cares for chicks.

Pair Selection

Select breeding birds based on:

  • Body conformation (straight legs, good muscle development)
  • Temperament (calm birds are easier to handle)
  • Fertility history (previous hatch rates above 60 percent)
  • Genetic diversity to avoid inbreeding

Genetic studies of emu populations in Japanese farms have used microsatellite DNA analysis to assess diversity (https://doi.org/10.1007/s11033-020-05335-4). Maintaining genetic diversity reduces the risk of inherited disorders and improves fertility.

Breeding Season Management

The breeding season lasts 4 to 6 months. Provide nesting areas with soft substrate (sand or straw) in quiet locations. Collect eggs twice daily to prevent breakage or contamination. Record egg weight, date, and parentage for each egg.

Fertility typically ranges from 60 to 80 percent. If fertility drops below 50 percent, evaluate nutrition (especially vitamin E and selenium), age of birds, and environmental stressors.

Incubation by Males

In natural incubation, the male sits on the nest for 48 to 52 days, leaving only to drink and eat briefly. During this period, the male loses 10 to 20 percent of body weight. Provide food and water within 3 meters of the nest. Do not disturb the male during incubation unless necessary.

Health Management and Disease Prevention

Emus are generally hardy but susceptible to several infectious and metabolic diseases. A preventive health program reduces losses and improves productivity.

Vaccination and Parasite Control

No commercial vaccines are specifically licensed for emus in most countries. Some veterinarians use poultry vaccines off-label for diseases like Newcastle disease and fowl pox. Consult a veterinarian for a vaccination schedule appropriate to your region.

Internal parasites (roundworms, tapeworms) can cause weight loss and diarrhea. Fecal egg counts should be performed quarterly. Treat with anthelmintics approved for poultry or ratites under veterinary guidance.

External parasites (mites, lice) cause feather damage and skin irritation. Dust baths with diatomaceous earth or approved insecticides help control infestations.

Common Diseases

Infectious Coryza: An outbreak of infectious coryza caused by Avibacterium paragallinarum was reported in an emu farm in Tirupati, Andhra Pradesh, India (https://doi.org/10.20546/IJCMAS.2019.803.167). Clinical signs included coughing, sneezing, and severe swelling of the infraorbital sinus. Mortality was high in chicks. Diagnosis was confirmed by PCR. Isolate affected birds and consult a veterinarian for treatment options.

Aspergillosis: An outbreak of Aspergillus fumigatus was reported in an organized emu farm in Indore, India (https://www.semanticscholar.org/paper/d021afdb532cbf309bd20d67e961fcb96c43856c). This fungal infection is associated with contaminated feed or bedding. Prevent by using clean, dry litter and storing feed in rodent-proof containers.

Eastern Equine Encephalitis (EEE): An EEE outbreak occurred at an emu farm in Atlantic County, New Jersey (https://www.semanticscholar.org/paper/780176ccc5b64f3bfb6afc5a0fa68565ddc02e4b). Mosquito-borne viruses can cause neurological signs and mortality. Control mosquitoes through environmental management and approved larvicides.

Erysipelothrix rhusiopathiae: This bacterium can cause septicemia in emus (https://pubmed.ncbi.nlm.nih.gov/19733019). Clinical signs include sudden death, depression, and skin lesions. Diagnosis requires bacterial culture. Consult a veterinarian for treatment and prevention.

Biosecurity and Record Keeping

Maintain a flock health record that includes:

  • Mortality and culling dates with causes
  • Treatments administered (product, dose, route, withdrawal period)
  • Vaccination dates and products used
  • Feed batch numbers and consumption rates
  • Water quality test results

The USDA National Agricultural Library provides resources on animal health and welfare (https://www.nal.usda.gov/animal-health-and-welfare). The FDA Animal and Veterinary resources cover medication use in food animals (https://www.fda.gov/animal-veterinary).

Oil Extraction and Processing

Emu oil is the most valuable product from emu farming, used in cosmetics and nutraceuticals. The oil is extracted from the fat pad located on the back of the bird.

Fat Harvesting

At slaughter, remove the fat pad (typically 2 to 5 kilograms per bird) and trim away muscle and connective tissue. Chill the fat to 4 degrees Celsius within 2 hours of harvest. Render within 24 hours or freeze for later processing.

Rendering Methods

Low-temperature rendering preserves the oil's bioactive compounds. Two common methods:

Wet rendering: Grind fat and heat with water to 60 to 70 degrees Celsius for 2 to 4 hours. Skim oil from the surface, filter through cheesecloth, and store in airtight containers.

Dry rendering: Grind fat and heat in a steam-jacketed kettle at 60 to 70 degrees Celsius for 3 to 5 hours. Strain through a fine mesh filter. Centrifuge to remove residual solids.

A study on chemical characterization and in vivo toxicological safety evaluation of emu oil confirmed its safety for topical use (https://pubmed.ncbi.nlm.nih.gov/35684037). The oil contains high levels of omega-3 and omega-6 fatty acids.

Quality Control

Test each batch for:

  • Free fatty acid content (should be below 2 percent)
  • Peroxide value (should be below 5 meq/kg)
  • Color (clear to light yellow)
  • Odor (mild, not rancid)

Store oil in amber glass or stainless steel containers away from light and heat. Shelf life is 12 to 18 months when stored properly.

Meat Processing and Marketing

Emu meat is lean, high in protein, and low in cholesterol compared to beef. It is classified as red meat despite being from a bird.

Slaughter and Processing

Emus should be processed at a USDA-inspected facility if meat is sold commercially. The slaughter process involves:

  • Stunning (electrical or captive bolt)
  • Exsanguination (bleeding for 3 to 5 minutes)
  • Scalding (60 to 65 degrees Celsius for 2 to 3 minutes)
  • Defeathering (mechanical or hand plucking)
  • Evisceration (remove internal organs within 30 minutes)
  • Chilling (cool carcass to 4 degrees Celsius within 4 hours)

Cuts and Yields

A 50-kilogram emu yields approximately:

  • 20 to 25 kilograms of meat (dressed weight)
  • 4 to 8 liters of oil
  • 1.5 to 2.0 square meters of leather
  • 1 to 2 kilograms of feathers

Primary meat cuts include:

  • Drumsticks (similar to turkey legs)
  • Fan fillet (tenderloin from the thigh)
  • Inside and outside rounds (from the thigh)
  • Oyster (small tender cut from the hip)

Marketing Channels

Identify target markets before slaughter. Potential channels include:

  • Direct sales to consumers (farm store, farmers markets, online)
  • Restaurants and specialty food stores
  • Wholesale distributors
  • Export markets (if certified)

Emu meat is not widely available in mainstream grocery stores. Educate customers on cooking methods (emus meat is very lean and benefits from marinating or slow cooking).

Leather and Feather Products

Emu leather is prized for its unique pattern (quill follicles create a raised dot pattern) and durability. Feathers are used in crafts and fashion.

Leather Processing

Raw hides must be salted or frozen within 2 hours of removal. Tanning is typically done by commercial tanneries specializing in exotic leathers. The leather is used for boots, belts, handbags, and upholstery.

Feather Uses

Emu feathers are used for:

  • Fly tying (fishing lures)
  • Millinery (hat decoration)
  • Costume design
  • Dusting tools (feather dusters)

Grade feathers by length and color. Natural colors range from brown to black. Dyed feathers command higher prices in some markets.

Records and Measurements

Accurate records are essential for evaluating farm performance and making management decisions.

Production Records

Track these metrics monthly:

  • Number of eggs laid per breeding female
  • Fertility rate (percentage of eggs with visible embryo at candling)
  • Hatch rate (percentage of fertile eggs that hatch)
  • Chick survival to 8 weeks
  • Mortality by age group
  • Feed conversion ratio (kilograms of feed per kilogram of gain)
  • Average daily gain

Financial Records

Maintain separate accounts for:

  • Feed costs (by age group)
  • Veterinary and medication expenses
  • Labor costs
  • Utilities (electricity, water)
  • Processing and marketing costs
  • Revenue by product (meat, oil, leather, feathers, eggs)

Benchmarking

Compare your farm's performance to published benchmarks. If mortality exceeds 15 percent in chicks or 5 percent in adults, investigate causes and consult a veterinarian. If feed conversion exceeds 5:1 in grow-out birds, evaluate feed quality and management practices.

Common Failure Patterns

New emu farmers often encounter these problems:

High chick mortality: Caused by inadequate brooder temperature, poor sanitation, or nutritional deficiencies. Solution: Verify brooder temperature with a thermometer at chick height, clean brooder daily, and use a balanced starter ration.

Low fertility: Caused by inbreeding, poor nutrition, or stress. Solution: Introduce new genetics from unrelated flocks, supplement with vitamin E (100 IU per kilogram of feed) and selenium (0.3 ppm), and minimize disturbances during breeding season.

Leg problems in chicks: Caused by slippery flooring, rapid growth, or mineral imbalances. Solution: Use non-slip surfaces, slow growth by reducing protein to 20 percent after 4 weeks, and ensure calcium-to-phosphorus ratio of 2:1.

Respiratory disease outbreaks: Caused by poor ventilation, high ammonia levels, or introduction of infected birds. Solution: Increase ventilation, clean litter frequently, and quarantine new birds for 30 days.

Low oil yield: Caused by slaughtering birds too young or with insufficient fat cover. Solution: Slaughter birds at 14 to 18 months when fat pad is fully developed.

Welfare and Safety Context

Emu welfare is important for ethical production and product quality. The USDA Agricultural Research Service provides resources on animal production and protection (https://www.ars.usda.gov/animal-production-and-protection).

Welfare Indicators

Monitor these welfare indicators weekly:

  • Body condition score (1 to 5 scale, target 3 to 4)
  • Feather condition (smooth, intact feathers indicate good health)
  • Gait and leg health (no limping or swelling)
  • Behavior (active, alert birds are healthy)
  • Feed and water intake (should be consistent)

Handling and Transport

Emus can kick forward and downward with powerful legs. Use handling equipment designed for ratites (raceways, crush pens) to minimize stress and injury. Transport birds in well-ventilated vehicles with non-slip flooring. Maximum transport time without feed and water is 24 hours.

Worker Safety

Emus can cause serious injury to handlers. Follow these safety practices:

  • Wear steel-toed boots and long pants
  • Use a catching shield or board when handling adult birds
  • Never approach an emu from behind
  • Work in pairs when handling breeding males
  • Keep children away from adult birds

Frequently Asked Questions

What is the initial investment required for an emu farm?

Initial costs include fencing, shelter construction, incubators, brooder equipment, and purchase of breeding stock. A small farm with 10 breeding pairs may require USD 20,000 to 50,000 for setup, depending on location and existing infrastructure. Operating costs include feed, veterinary care, utilities, and labor.

How long does it take for emus to reach slaughter weight?

Emus reach slaughter weight of 40 to 55 kilograms at 12 to 18 months of age. Growth rate depends on genetics, nutrition, and management. Birds slaughtered at 14 to 16 months typically have the best balance of meat yield and oil content.

What is the profit potential for emu farming?

Profitability depends on market prices for meat, oil, leather, and feathers. A single emu can generate USD 500 to 1,500 in revenue from all products. Costs per bird (feed, processing, marketing) range from USD 200 to 400. Net profit per bird varies widely based on scale, efficiency, and market access.

Can emus be raised with other livestock?

Emus can be raised with other poultry or livestock if biosecurity measures are in place. However, they may compete for feed and can be aggressive toward smaller animals. Separate paddocks are recommended to prevent disease transmission and injury.

What are the main diseases affecting emus?

Common diseases include infectious coryza, aspergillosis, Eastern equine encephalitis, and erysipelas. Emus are also susceptible to internal and external parasites. A preventive health program with regular veterinary consultation reduces disease risk.

How is emu oil used?

Emu oil is used in cosmetics (moisturizers, anti-aging creams), nutraceuticals (joint health supplements), and topical treatments for skin conditions. The oil contains omega-3 and omega-6 fatty acids and has anti-inflammatory properties. It is applied topically or taken orally as a supplement.

What permits are needed for emu farming?

Permits vary by country and region. In the United States, emus are classified as poultry by the USDA. Farms selling meat must process at USDA-inspected facilities. Check with state agriculture departments for specific requirements regarding zoning, waste management, and product sales.

How do I market emu products?

Direct marketing through farm stores, farmers markets, and online platforms is effective for small farms. Build relationships with local restaurants and specialty food stores.
