Chicken and beef production are two of the most common forms of meat production, with poultry and cattle being the dominant livestock types. However, the production of chicken and beef comes with several environmental and ethical concerns. For instance, the feed conversion ratio (FCR) for beef is much higher than that of chicken, meaning it takes more feed to produce a pound of beef than chicken. This results in a higher land requirement for beef production, contributing to environmental issues such as deforestation and greenhouse gas emissions. While chicken production may have a lower FCR, it still contributes to environmental issues, particularly in communities where chicken farms are concentrated, with air pollution and waste buildup causing health issues for residents.

What You'll Learn
Feed conversion ratio
FCR is calculated by dividing the mass of the input (feed) by the output (body mass). In other words, it quantifies the amount of feed required to increase an animal's weight by a specific amount. For example, it takes 25 kilograms of feed to produce one kilogram of beef, resulting in an FCR of 0.04.
FCR values vary across different species of livestock. Chickens are more efficient at converting feed into body mass than cows. The FCR for broiler chickens in the US in 2011 was 1.6 based on body weight gain, while the global average in 2013 was around 2.0 for live weight and 2.8 for slaughtered meat (carcass weight). In contrast, beef cows have a significantly higher FCR, often cited as 25:1, indicating that they require substantially more feed to gain weight.
The improvement in genetics for meat production in chickens has led to a decrease in their FCR over time. From the early 1960s to 2011 in the US, broiler growth rates doubled, and their FCRs halved due to advancements in genetics and the rapid dissemination of improved chicken breeds.
It is important to note that the inherent loss of crops and natural resources in meat production highlights the inefficiency of the process. While chickens have a lower FCR than cows, they still consume more than twice as many calories and protein than they produce. This illustrates the inherent wastefulness of cycling crops through animals, as it results in a net loss of available global calories and protein.

Energy subsidies
Environmental Impact of Energy Subsidies
However, energy subsidies in the context of chicken and beef production have also been criticised for their environmental implications. The energy required for meat production, including feed production, farming, and transportation, contributes significantly to greenhouse gas emissions. By subsidising energy sources that are not environmentally sustainable, governments may inadvertently encourage higher emissions and contribute to climate change. This is particularly relevant when energy subsidies support intensive farming practices that require significant energy inputs.

Alternatives and Policy Reforms
There have been calls for policy reforms to address the environmental impact of energy subsidies in chicken and beef production. One proposed solution is to redirect energy subsidies towards renewable energy sources and sustainable agricultural practices. By incentivising the use of cleaner energy technologies and more efficient farming methods, governments can reduce the environmental footprint of the meat industry. Additionally, removing subsidies from fossil fuels used in meat production can help level the playing field for alternative protein sources, such as plant-based options, making them more competitively priced.
Global Impact and Trade
It is important to consider the global impact of energy subsidies in chicken and beef production, especially in the context of international trade. Energy subsidies in developed countries can influence the competitiveness of agricultural exports, affecting the global market. This can have both positive and negative consequences, as it may increase access to affordable protein sources in some regions, while also disrupting local agriculture and food systems in other parts of the world. Balancing the economic benefits of energy subsidies with their environmental and societal costs is a complex challenge for policymakers.

Environmental impact
The global meat industry has significant environmental consequences, and as the industry grows, so does its environmental impact. Agriculture, including meat production, has a large environmental impact in three key ways: water usage, land use, and emissions.
Firstly, agriculture requires large amounts of freshwater, which can cause environmental pressures in regions with water stress. It also pollutes rivers, lakes, and oceans by releasing nutrients. For example, it takes 1,845 gallons of water to produce one pound of beef. In contrast, plant-based alternatives use less water and lack the water pollution caused by the accumulation of animals' manure. However, certain crops used in plant-based alternatives, such as soy and wheat, can contribute to waterway eutrophication and herbicide pollution.
Secondly, agriculture is a significant driver of climate change, responsible for around one-quarter of the world's greenhouse gas emissions. Within the meat industry, beef typically has the largest emissions, followed by lamb, pork, and chicken. This is because larger animals tend to be less efficient and have a higher carbon footprint. For instance, producing 100 grams of protein from beef emits 25 kilograms of carbon dioxide on average. Additionally, the feed-crop production and manure associated with Concentrated Animal Feeding Operations (CAFOs) contribute significantly to air and water pollution and climate-warming emissions. Chicken CAFOs, in particular, have been linked to water quality decline and a loss of biodiversity and ecosystem health due to their geographical concentration in delicate ecosystems.
Lastly, agriculture requires enormous land use, with half of the world's habitable land being used for this purpose. The land required for grazing and growing feed crops for livestock contributes to the loss of natural habitats and a reduction in biodiversity.
While switching from beef to chicken may seem like a more sustainable choice due to chicken's lower emissions per serving, it is not a climate-friendly option. The overall rise in cheap chicken consumption increases the environmental impact, as more animals are slaughtered for the same amount of protein. Therefore, adopting a more plant-based diet and reducing consumption of carbon-intensive foods such as meat and dairy is the most effective way for consumers to reduce their carbon footprint.

Meat consumption
Chicken and beef production have different requirements and impacts. For example, it takes more than seven times as much grain to produce 1 kg of beef compared to poultry, and beef production has a higher feed conversion ratio (FCR), meaning it takes more feed to create a pound of beef than a pound of chicken. However, chickens consume more than twice as many calories and protein than they produce, making them inefficient converters of crops.
The environmental impact of meat production is significant. Beef production is one of the least efficient forms of food production due to the high amount of feed and land required. Clearing land for pasture can lead to environmental impacts such as soil erosion and salinization. Factory farming of chickens can also have negative consequences, including waste buildup, pollution, and the displacement of local communities.
To address the environmental challenges associated with meat production, alternative production systems and dietary changes have been proposed. Well-managed pasture-raised beef can help build soil carbon and reduce greenhouse gas emissions. Organic poultry production aims to provide better welfare for chickens, but issues with densely stocked chicken houses remain. Reducing meat consumption and choosing more sustainable options, such as cultivated meat, can also help mitigate the environmental impact of meat production.
Cultivated meat is expected to have several benefits over conventional animal agriculture due to its controlled and efficient production process. It requires less land and causes less air pollution, soil acidification, and marine eutrophication. Additionally, it is produced without antibiotics, reducing the risk of foodborne illnesses. However, as of 2024, only a few cultivated meat products have been approved and sold in select markets.

Industrial chicken production
Chicken meat production began with the development of the broiler—a chicken raised specifically for its meat. The commercial broiler industry began its economic boom in 1952 when specially bred meat chickens ("broilers") surpassed farm chickens as the number one source of chicken meat in the United States. Factors in the geographic expansion of the industry included favourable weather conditions, adequate land and water, and access to supplies of corn and soybeans, which are the major components of poultry feed.
Broiler chickens are raised to maturity in grandparent growing and laying farms, where fertile eggs are produced. Pullets hatch from the fertile eggs and are sent to breeder houses, where they produce more fertile eggs, which are sent to hatcheries. Shortly after the eggs hatch, the chicks are sent to broiler farms, where they are raised according to company standards. When the broilers reach the desired processing weight, they are sent to processing plants. The finished chicken products are then sent to distribution centers and transported to customers.
Broiler farms are the final stage before processing for consumers, so the birds are closely monitored for health issues to ensure a wholesome product. Broiler houses are the most densely stocked poultry houses, with less than one square foot allocated per individual bird at their final weight. A modern 60 x 600-foot broiler house may grow 36,000 to 52,000 chickens. Broiler growers work under the supervision of company field technicians and must pay close attention to bird health, quickly communicating any health issues to company personnel and veterinary staff.
Chicken is the most efficient of the meat proteins in feed conversion. It takes less feed to create a pound of chicken than a pound of beef. In 1925, it took 16 weeks and almost 12 pounds of feed to grow a 2.5-pound chicken. Today, a chicken more than twice that size can be grown in less than half the time with only 11 pounds of feed. In addition to diet, advances in selective breeding, improved production technologies, and better management practices have enabled the industry to grow broilers faster and with less feed.
