Antibiotics in Broiler Chicken Production: An Overview
Antibiotics have been used in poultry farming for many years. They help chickens grow faster, fight off diseases, and change their gut and immune system. In North America, especially, many antibiotics are used, like tetracyclines, bacitracin, tylosin, salinomycin, virginiamycin, and bambermycin.
Antibiotic Use in Poultry Farming
In the U.S., tetracyclines make up more than two-thirds of animal antibiotics. But in the European Union, they are used in only 37% of veterinary antibiotics. The EU doesn’t allow antibiotics to be used as growth promoters.
Types of Antibiotics Commonly Used
There are many types of antibiotics used in poultry farming. These include tetracyclines, bacitracin, tylosin, salinomycin, virginiamycin, and bambermycin. They help chickens grow faster, fight diseases, and change their gut and immune system.
“Global antibiotic use increased by 39% between 2000 and 2015, with food animals consuming approximately 131,000 tons of antibiotics in 2013, a figure projected to rise to 200,000 tons by 2030.”
The use of antibiotics in poultry farming worries many. It could lead to antibiotic-resistant bacteria and harm human health. So, rules and practices are changing to use antibiotics more wisely.
The Role of Antibiotics in Broiler Chicken Production: Pros and Cons
Antibiotics have been key in broiler chicken production for a long time. They help in growth, improve feed use, and fight diseases. But, they also have downsides.
Now, more than 50% of chicken is raised without antibiotics. This shows a shift towards better practices. Antibiotics for humans are only for sick animals, not for growth. Yet, most chicken antibiotics are not for human use.
Despite progress, there’s a big worry about antibiotic resistance in food, especially in poultry. Antibiotics have been used to grow chickens in Europe. In the U.S., from 1998 to 2012, poultry was a major source of foodborne outbreaks. Salmonella and antibiotic resistance in broilers are big concerns for food safety.
Probiotics are being looked at as a safer option for chicken health. But, the link between bacteria in animals, humans, and the environment is complex. It shows we need a full plan to keep poultry food safe.

We need better ways to keep poultry food safe. The current issues with antibiotic resistance and foodborne illnesses are big challenges.
“The use of probiotics in poultry production has been explored as an alternative to antibiotics in promoting animal health.”
Promoting Growth and Feed Conversion
Antibiotics have been used in chicken farming to help chickens grow faster and use feed better. Studies show that chickens treated with antibiotics can grow up to 5% more than those without. This is because antibiotics help control infections and improve how the gut absorbs nutrients.
Impact on Weight Gain and Feed Efficiency
The use of growth promotion antibiotics in chicken farming boosts weight gain and feed efficiency. Chickens treated with antibiotics need less food to reach the same weight as those not treated. This makes farming more cost-effective and sustainable.
“Antibiotic growth promoters induce specific changes in the cecal microbiota membership of broiler chicken.”– Costa MC, et al., 2017
But, using antibiotics for growth has raised concerns about antibiotic resistance. This has led to debates about the ethics of using antibiotic-treated chickens. Many are calling for more eco-friendly and responsible farming methods.
Disease Prevention and Treatment
Antibiotics are key to keeping broiler chickens healthy. They help with growth and fight off diseases. This has made the poultry industry grow a lot over 50 years.
Antibiotics work best against bacterial infections. They either kill the bacteria or stop them from growing. This lets the chicken’s immune system fight off the infection better. Even though they don’t work on viruses or fungi, antibiotics are vital for treating infectious diseases, bacterial infections, and avian diseases in chickens.
- Two important antibiotics, fluoroquinolones and cephalosporins, are no longer used in chicken farming.
- By December 2016, antibiotics important for humans will only be used in animals for treating diseases, not for growth.
- FDA has removed 31 antibiotic products from the market in the United States.
Using antibiotics wisely, like bacitracin to stop necrotic enteritis, is important. Also, using non-antibiotic options like ionophores and coccidiostats helps. This way, we avoid overusing antibiotics in chickens. It’s key for keeping chickens healthy and productive.
“Restricting antibiotic use in food-producing animals can reduce antibiotic-resistant bacteria in these animals by up to 39%.”
Modifying Gut Microbiota and Immunity
Antibiotics in broiler chicken production deeply affect their gut microbiota and immune system. They change the types and amounts of microbes in the intestine. This helps the birds grow and develop better.
Changes in Intestinal Microbiome
Research shows antibiotics like salinomycin and virginiamycin change the chicken gut microbiome. For example, these antibiotics increase Lactobacillus species in the intestine. On the other hand, antibiotics like tylosin lower Lactobacillus spp. in the chicken ileum.
Effects on Immune System
Antibiotics alter the gut microbiota, affecting broiler chickens’ immunity and health. A 2012 study by Khodambashi Emami et al. looked at peppermint essential oil and fructooligosaccharides as antibiotic alternatives. They studied their effects on growth, gut health, and immune response.
“Phasing out antibiotic growth promoters (AGPs) in poultry diets is expected to alter the microbial profile of the intestinal tract, potentially influencing poultry flocks.”
Lee KW et al.‘s 2012 study explored how anticoccidial and antibiotic growth promoters affect broiler performance and immune status. It showed the complex relationship between gut microbiota, immunity, and production.
Food Safety and Contamination Risks
Antibiotics in chicken farming can worry us about food safety. Bacteria like Campylobacter, E. coli, and Salmonella are common in chicken and eggs. Antibiotics can make these bacteria grow more.
Studies show that bacteria in chicken and eggs can resist many drugs. This is because resistant bacteria spread in the intestines and along the food chain. Health agencies worldwide watch these infections closely. They affect millions of people every year.
Antibiotic-Resistant Bacteria in Meat and Eggs
More people want food without antibiotics, up 25% from 2009 to 2012. But, even organic and “antibiotic-free” foods can have resistant bacteria. They just have a bit less than regular chicken.
- In 2011, 81% of ground turkey, 69% of pork chops, 55% of ground beef, and 39% of chicken had resistant bacteria in U.S. stores.
- Almost 25% of beef, poultry, and pork in U.S. stores had MRSA in 2011.
- Chicken without antibiotics still had antibiotic-resistant E. coli in a study.
The poultry industry is trying to use fewer important antibiotics. Now, over 50% of U.S. broiler chickens are raised without antibiotics. But, there are still worries about animal health and food safety. Diseases like coccidiosis and necrotic enteritis are concerns.
| Metric | Value |
|---|---|
| Sales of medically important antimicrobials for use in food-producing animals | Decreased by 38% from 2015 to 2018 |
| People infected with bacteria resistant to antibiotics annually in the U.S. | Around 2.8 million |
| People who die each year in the U.S. from infections caused by resistant bacteria | At least 35,000 |
“More than 50% of broiler chickens in the U.S. are now raised in ‘no antibiotics ever’ (NAE) programs.”
Antibiotic Resistance and Public Health Concerns
The use of antibiotics in raising broiler chickens has led to more resistant bacteria. This is a big worry for public health. Even though the term “superbug” might sound scary, the FDA says it’s a real problem.
Broiler farms have more resistant bacteria than other farms. They use more antibiotics on each chicken every year. In Tanzania, 75% of bacteria near chicken farms were resistant to many drugs. This is compared to 53.1% in areas without farms.
Rise of Multidrug-Resistant Pathogens
Using too many antibiotics in chicken farms has made some bacteria very hard to kill. These “superbugs” can get into our food and harm us. In the U.S., most antibiotics are used on animals, making the problem worse.
Even though chicken farms are using fewer antibiotics, the problem of resistance is still big. Up to 80% of antibiotics given to animals end up in manure and urine. This can spread resistant genes into the environment.
The FDA and health experts are watching this closely. They want antibiotics used wisely in animal farming. Chicken producers are trying new ways to fight disease without antibiotics. But, doctors, farmers, and the public must also help keep antibiotics working.
Regulatory Landscape and Industry Practices
Concerns about antibiotic resistance have led to changes in how antibiotics are used in broiler chicken production. In the United States, new rules in 2017 limited antibiotics important for humans to only treating diseases. This means these antibiotics can no longer be used to make chickens grow faster.
In the European Union, antibiotics to make animals grow have been banned since 2006. Poultry farms are now using antibiotics only when needed, with a vet’s approval. This is part of their effort to use antibiotics wisely.
Restrictions on Growth Promoters
Rules now limit the use of antibiotics to help chickens grow. This change aims to stop antibiotic-resistant bacteria from spreading. Now, farmers must get a vet’s okay before using antibiotics.
Veterinary Oversight and Responsible Use
Poultry farms are working hard to use antibiotics wisely. They have more vet checks, better cleanliness, and use new methods to keep animals healthy. They’re also looking into new ways to replace antibiotics.
“Antibiotics are a critical tool for protecting the health and welfare of animals, but their use must be carefully managed to preserve their effectiveness and minimize the risk of antibiotic resistance.”
The rules and practices around antibiotics in chicken farming are changing. This shift shows a focus on using antibiotics responsibly. By making these changes, the poultry industry aims to keep antibiotics effective for the future.
Alternatives to Antibiotics in Broiler Production
The poultry industry is looking for ways to use fewer antibiotics. They are exploring antibiotic alternatives to keep broiler chickens healthy and productive. These include probiotics, prebiotics, essential oils, vaccination, and better biosecurity practices.
Probiotics, Prebiotics, and Essential Oils
Probiotics and prebiotics are being studied for their benefits. They help keep the gut healthy and support the immune system in chickens. Probiotics, like Lactobacillus and Bifidobacterium, fight off harmful bacteria. Prebiotics, such as oligosaccharides, feed these good bacteria, boosting gut health.
Essential oils from plants are also being looked at as antibiotic alternatives. For example, cinnamon oil has shown to fight bacteria in the chicken’s gut.
Vaccination and Biosecurity Measures
Vaccination and better biosecurity are also key. Vaccines help prevent diseases like necrotic enteritis and coccidiosis. These diseases have become more common since antibiotics are used less.
Good biosecurity practices, like keeping facilities clean and controlling who enters, also help. These steps reduce the chance of disease and the need for antibiotics.
By using a mix of these alternatives and responsible antibiotic use, the poultry industry aims to keep animals healthy. They also want to fight antibiotic resistance and support sustainable poultry production.
“Consistency is vital for antibiotic-free poultry production. Producers must be willing to invest in alternative management strategies and continuously adapt their practices to ensure the long-term success of their antibiotic-free operations.”
Using antibiotics in broiler chicken production is a complex issue. It has both good and bad sides. Antibiotics help chickens grow and fight off diseases. But, they also lead to antibiotic-resistant bacteria, which is bad for public health.
To fix this, the poultry industry and regulators need to find a middle ground. They should use antibiotics wisely and explore other options like probiotics and vaccines. This way, they can keep chickens healthy and safe for us to eat.
It’s important for everyone involved to work together. This includes the industry, government, and scientists. They need to find ways to keep chickens healthy, protect the environment, and ensure our food is safe. By doing this, the chicken industry can meet our needs for affordable, healthy food without harming the planet or our health.
