Broiler Production in the United States
• 8.0 Billion broilers Per Year
• Trend toward larger birds for processing(2.5 kg. and larger)
• Most broilers are deboned and meat is used for Fast food industry, restaurants, and prepared foods
Historical Drug Usage in Broiler Production
1. Ionophore Coccidiostats:MonensinSalinomysinNarrison
2. Chemical Coccidiostats:AmprolNicarbazineHalofuginoneDiclazaril
3. Sub-therapeutic AntibioticsBacitracinsVirginiamycinLincomysinBambermysins
American Consumer !
• Desire less drugs and antibiotic use in Food Animals
• Ultimate desire is Drug-Free and Antibiotic Free Products
Demand for Drug-Free and Organic Poultry are being met by:
• Small Poultry Companies• Gerber Poultry
(250,000 / week)• Petaluma Poultry
(250,000 / week)• Farmer’s Pride
(300,000 / week)
Demand for Drug-Free and Organic Poultry are being met by:
• Large Poultry Companies designating some production in specific operations
• Tyson FoodsVirginia Complex
• Fieldale FarmsGeorgia
Designated Terms as Defined by the United States department of Agriculture (USDA)
• Drug-Free” No ionophore Coccidiostat use
No sub-therapeutic or therapeutic antibiotic useUse of Chemical Coccidiostats
• Antibiotic – FreeNo sub-therapeutic or therapeutic antibiotic useMay use ionophore and chemical
Coccidiostats
Designated Terms as Defined by the United States department of Agriculture (USDA)
• Natural Chicken:No real meaning, has no restrictions
• Hormone – Free ( ?????)Hormones are not used in Poultry Production
• “Organic Chicken” All feed fed must be organically grown (define) No use of Antibiotics or ionophore coccidiostats Can use chemical coccidiostats
Main Obstacle in Drug-Free and Organic Production:
Coccidiosis Control
Secondary Clostridia Perfrengens Control
Current Coccidiosis Control is by use of Coccidiosis Vaccine
• All current vaccines are live vaccine which require cycling to develop immunity
• The developing of Immunity requires completion of life cycle of coccidia in the intestinal tract which can lead to clostridial invasion and resulting in necrotic enteritis
Use of Feed Additives to limit effects of Coccidial and Clostridial Invasion
• Organic Acids
• Oregano
• Probiotics
• Other Products
• None have shown good benefits in Commercial use
Management Changes to Limit effects of Coccidia and Clostridia
• Decrease number of Broilers per square meter
• Use of Litter Acidifiers
Solve The Problem
