Alternative Poultry Production Systems Enriched cages Cage-free Aviaries
Outdoor access • Allows birds to express natural behaviors (foraging, dustbathing). • Can provide a healthy environment • Ample space • UV sunlight • Fresh air • “Extensive production” vs. “intensive production”
USDA definition for free-range poultry; not very • specific • “Free-range” permitted on labels after review process • Producer submits description of production • Livestock have free access to out-of-doors for at least 51% of their lives”
Example of Definitions: European Union • Free-Range • Finishing feed must at least 70% cereal (low protein) • Minimum age at slaughter: chickens must be 56 days of • age or older • Maximum stocking density for indoor area: 13 chickens • per 10.8 ft2 (with a maximum of 59.5 lbs of total • liveweight) • 13 ft of pophole per 1076 ft2 of house • Outdoor area mainly covered by vegetation • Birds must have outdoor access for at least half of their • lifetime • Maximum stocking density for outdoor area: 1 chicken • per 10.8 ft2 (4033 chickens/ac)
Traditional Free-Range • Strains: only slow-growing • Minimum age at slaughter: chickens must be at least 81 days • Finishing feed must be at least 70% cereal • Maximum stocking density for indoor area: 12 chickens • per 10.8 ft2 (with a maximum of 55 lbs of total liveweight) • Maximum stocking density can be increased to 20 chickens • if doors are left open at night • 13 ft of pophole per 1076 ft2 of house • Flock size (house): House can’t have more than 4,800 chickens • Flock size (site): 17,222 ft2 of poultry houses at a single site • (limits number of birds) • Chickens must have outdoor access after 6 weeks • Maximum stocking density for outdoor area: 21.6 ft2 per chicken • (2026 chickens per acre)
Free-Range Production Systems: Fixed House and Yard
Large-scale Automated house Subdivide yards In order to rotate Or rest pasture
Portable housing Moved frequently or infrequently
On wheels Eggmobile
Pasture pens Cons: Very labor-intensive to move pens daily by hand, provide little protection from the elements Pros: Flexible, low-cost, good for beginners
Portable shelter Pasture pens are moved daily
Floorless Shelter
Integrated Poultry Production Poultry manure good for building soil fertility for gardens and pastures, organic fertilizer encourages earthworms Cattle parasite control Sheep manage sward for poultry Stagger species in paddock Graze simultaneously Cattle and goats may disturb poultry housing Exclusion feeding Complementary with vegetable production
“Chicken Tractor” Poultry raised with vegetable production for: fertility tillage weed control pest control
“Stack” enterprises: hoophouse overwinters rabbits and layers; grows early vegetables
Look back in history
Land Management Provide the same services outdoors as indoors Feed and water outside encourages birds to go outside
Provide shade and shelter Chickens do not like open range
Provide sufficient popholes so birds can find their way outside
Pasture management Poultry obtain limited nutrients from forage Keep forage short and vegetative
Forage is usually planned for the ruminants • Diverse pasture needed • Cool season: oats; warm-season: clover, alfalfa • Legume forages increase omega-3 fatty • acids in eggs and meat
Dryland provides little green forage but has other benefits of outdoor access
Rotate pastures every 2-3 months • Mobile house is ideal • If house is fixed, subdivide yard into • at least 4 yards
Multiple yarding Source: Thear, 1997
Consequences of • not rotating/resting: • Turf damage • Pathogens build up • Excessive nutrients
Predator Control • Ground predator control: • Electronet fencing • Humane traps • Overhead predator control: • Net covering • Interfere with flight • Long rectangle yards • String • Guardian dogs
Housing Housing protects chickens from rain, wind, sun, predators, Insulation reduces temperature extremes Many styles depending on Shelter vs. house Fixed vs. portable
Materials: • Built of wood, sheet metal, poultry wire • Concrete, brick • Developing countries: Adobe, bamboo, thatch • Roof: • Rainproof: Tarps, sheet metal, shingles, wood • Roof should have a large overhang to provide shade and • prevent rain from getting in • Insulated • Power
Orient so birds are not exposed to direct sunlight Floor: dirt, gravel with wire mesh to keep out rats, concrete Raised floor: wood, slats Solid floor: use litter Make house easy to clean
Ventilation Usually natural because popholes open Makes use of air movement (hot air rises, cold air falls) Build roof high above floor to create differential Open side walls or curtains for cross ventilation Mechanical ventilation (fans) can help exhaust air out building more quickly Ventilation tricky in winter because producers keep house more tightly closed
Temperature If house is not heated, birds eat more in cold weather to stay warm Heat stress is more of a problem Should not be over 85 F in house, birds pant Use a thermometer to display recent high and low
Lighting Dark period is needed for good health Usually natural in alternative poultry production Usually bright Reduce intensity if aggression occurs Incandescent or fluorescent Artificial light important for managing layers Electrical, battery-powered, kerosene
Litter Litter dilutes manure Wood shavings, rice hulls Keep litter in good condition; wet litter causes many problems 30% moisture Clean out Litter provides nutrients for crops and forage Compost is good soil amendment
